Somatic-Dominant Type

🧠 Overview — What is Somatic-Dominant Type? 

Somatic-Dominant Type is a pattern of expressing stress, anxiety, or depression in which the brain chooses to send signals of distress through the body before it shows up as emotions — put simply, it is “the body speaking for the mind.” Instead of crying or saying “I’m stressed,” the brain communicates through pain, tightness, numbness, or dizziness directly, as if the body were a loudspeaker for worries that the mind doesn’t know how to put into words.

Clinically, people in this group often come to see doctors with chronic physical symptoms with no clear medical cause, such as headaches, muscle tension, chest tightness, shortness of breath, palpitations, dizziness, bloating, acid reflux, alternating diarrhea and constipation, feeling exhausted and drained all the time, or strange sensations like numbness, tingling, burning, or electric-shock-like feelings in different parts of the body — even though all test results come back normal.

What confuses doctors and people around them is that this group often firmly believes they have a physical illness, not an emotional or mental problem. When asked, “Are you stressed lately?” they often answer, “I’m a bit stressed, but that’s not it — this must be some real disease.” Some don’t even realize that they’re stressed at all, because their entire focus is glued to the body, to the point that they don’t notice the emotional changes happening inside.

The mechanism of this condition arises from the brain’s emotional-processing systems, such as the insula and anterior cingulate cortex, which control internal sensation awareness (overactive interoception) and are working in overdrive. As a result, the brain amplifies small bodily signals into something much louder than they actually are, making pain, tightness, and discomfort feel intense even though the organ itself is structurally normal. At the same time, the amygdala–HPA axis stress-response circuit releases cortisol and adrenaline, leading to palpitations, shortness of breath, cold hands and feet, or digestive disruption — and the brain takes this as further “evidence” that “Something is seriously wrong; I must be sick.”

The outcome is a continuous cycle of “worry → symptom monitoring → increased bodily tension → symptoms intensify → even more worry” that keeps spinning. This eventually turns into behaviors like repeatedly going to doctors, requesting more tests, switching hospitals, obsessively searching symptoms on Google, or trying all kinds of supplements on their own.

From a diagnostic classification standpoint in DSM-5-TR and ICD-11, this condition overlaps with Somatic Symptom Disorder, Illness Anxiety Disorder, or the “somatic presentations” of Depression, Anxiety, and PTSD. But using the term Somatic-Dominant Type helps explain things more clearly in practice: this refers to patients who do have an underlying emotional or mood disturbance, but what stands out most are the physical symptoms.

Another key dimension is culture — in societies where talking openly about mental health isn’t welcomed, saying “I have stomach pain and chest tightness” is much more acceptable than saying “I’m sad,” “I’m anxious,” or “I’m emotionally overwhelmed.” So the body becomes a safer communication channel. And when the brain learns that showing physical illness gets more attention, care, and concern from others, this cycle gets reinforced even more.

Overall, Somatic-Dominant Type is therefore a “translation of the language of stress into bodily symptoms”, while the person themselves may have no idea that the true origin lies in the brain and mind, not in the organs. Understanding this point is crucial, because it leads to a more integrated treatment approach — combining psychotherapy with balanced physical care — instead of endlessly searching for a new hidden physical disease.

Put visually, Somatic-Dominant Type is not “overthinking” or “making it up.” It is the brain asking for help through the body — and once we learn to understand this language, we can begin by treating the mind, so that the body can gradually calm down as well.

🧩 2) Core Symptoms — Core Symptoms of Somatic-Dominant Type 

The symptom profile in this group is highly complex and deceptive, because the brain and body are working so tightly together that it becomes hard to tell “what is a physical disease?” and “what is the brain expressing through the body?”
In general, symptoms fall into three major dimensions: Somatic, Cognitive-Emotional, and Behavioral Symptoms.

2.1 Somatic Symptoms (Physical Symptoms)

This is the most visible part — “the body speaking for the mind.”
They are very real symptoms — the pain is real, the discomfort is real — but they cannot be fully explained by pure physical pathology alone.

Examples include:

• A dull, chronic headache; a tight band-like pressure around the head; or the feeling of a weight pressing on the back of the head or nape.

• Muscle pain and stiffness in the neck, shoulders, and back, feeling tense every day as if carrying something heavy all the time, even without physical exertion.

• Chest tightness and the feeling of not being able to take a full breath; needing to sigh deeply repeatedly; or feeling like “food won’t go down,” as if something is stuck in the middle of the chest.

• Heart palpitations, hand tremors, easy sweating, unexplained hot flashes; in some people, feeling like they might faint every time they get stressed.

• Stomach pain, abdominal tightness, bloating, acid reflux, alternating diarrhea and constipation (similar to IBS).

• Dizziness, vertigo, or the sensation that “the world is tilting” without any abnormality found in the inner ear.

• Numbness, tingling, electric-shock-like sensations, or “strange burning” in the arms, legs, or face, even though EMG/nerve conduction studies are normal.

• Chronic fatigue that cannot be explained — waking up already tired despite sufficient sleep.

• These symptoms clearly worsen under stress, sleep deprivation, or emotional conflict.

Laboratory tests or imaging studies often come back “normal”, or show only mild findings that cannot fully account for the severity of the symptoms — for example, slight gastric acidity, but the person feels so tight and bloated they can hardly eat. This indicates that the brain has amplified these bodily signals beyond their actual intensity.

---

2.2 Cognitive-Emotional Symptoms (Thoughts and Emotions)

This dimension is about the brain misinterpreting bodily signals — an over-interpretation process.
The brain starts to believe that small, benign sensations are actually signs of a serious illness.

Examples include:

• Constant worry or preoccupation with having heart disease, cancer, or stroke, even when all test results are normal.

• Repetitive thinking (rumination) focused on bodily symptoms, such as: “Why do I still have this headache? Did the doctor miss something?”

• Repeated checking behaviors, such as palpating the pulse, checking blood pressure, or measuring blood oxygen levels many times a day.

• Searching for disease information in detail via Google or YouTube; the more they read, the more scared they become.

• Mood often fluctuates along with the fear — they are stressed, but refuse or fail to recognize that they are stressed.

• Some have masked depression — no clear sadness, but significant fatigue, poor appetite, and a pervasive sense of having no energy for life.

• They often say things like, “I’m not depressed, I’m just sick and no one has figured out what it is yet.”

• Fear of illness becomes a central force controlling their life, keeping the brain locked into a continuous “threat surveillance” mode.

---

2.3 Behavioral Symptoms (Behaviors Driven by the Symptoms)

These are the downstream consequences of fear and the intense need to “get an answer” about what is happening in the body.

Examples include:

• Frequent hospital visits within short periods of time.

• Switching doctors and hospitals repeatedly to “find someone who agrees with my fear.”

• Repeated investigations, such as requesting CT scans, MRIs, or ultrasound, even when previous tests were normal.

• Spending large portions of the day monitoring symptoms, searching for information, or complaining about physical problems.

• Avoiding physical activities, such as running or brisk walking, out of fear of causing a heart attack.

• Taking frequent sick leave from work or school due to the belief that the body is not strong enough.

• Taking multiple medications at once — conventional medicine, herbal remedies, and supplements — “in case one of them helps.”

• Feeling frightened or dismissed by doctors who say, “There’s nothing wrong with you,” and feeling safe only with doctors who “order more tests.”

• Over time, these behaviors form a cycle of “treat → feel a bit better → symptoms return”.

• This cycle exhausts both the patient and those around them because it appears as if they “only trust their body, and don’t trust anyone else.”

---

⚙️ 3) Diagnostic Criteria — Diagnostic Criteria 

The term Somatic-Dominant Type does not appear as an official disorder name in DSM-5-TR.
Instead, it is used more as a descriptive specifier for depression, anxiety, or other mental disorders when physical symptoms are the leading feature — typically overlapping with:

• Somatic Symptom Disorder (SSD)
• Illness Anxiety Disorder (IAD)
• and the “somatic presentations” of Depression / Anxiety / PTSD

3.1 Somatic Symptom Disorder (SSD) — Core DSM-5-TR Criteria

• There is one or more physical symptoms (e.g., pain, discomfort, or abnormal sensation in any bodily system) that cause genuine distress.

• These symptoms cause significant distress or impairment in daily functioning.

• At least one of the following three patterns is present:

• Excessive thoughts about the seriousness of the symptoms.
• Persistent high anxiety about health or symptoms.
• Excessive time and energy devoted to these symptoms or health concerns.

• The disturbance typically persists for at least 6 months, even if specific symptoms may change over time.

In Somatic-Dominant Type, most cases will meet SSD criteria — but what stands out is that “the body speaks first, emotions appear only as a shadow in the background.”

---

3.2 Illness Anxiety Disorder (IAD)

This is a condition in which there are few or minimal physical symptoms,
but there is an overwhelming fear of having a serious illness that is hard to control.

Key features include:

• Fear of serious diseases such as cancer, heart attack, or stroke, even when all test results are normal.
• Medical check-ups do not provide reassurance — they feel compelled to repeat tests with multiple doctors.
• Some avoid hospitals altogether because they are “afraid of hearing bad news.”
• This fear persists for more than 6 months.
• There are two subtypes: “Care-seeking” (frequent testing) and “Care-avoidant” (so fearful they avoid testing).

---

3.3 Specifiers or Types Related to Somatic-Dominant Presentations

In modern clinical psychiatry and research, the term “Somatic-Dominant” is often used to qualify existing disorders, for example:

Somatic-Dominant Depression

• The patient doesn’t say, “I feel sad,” but instead says,
  “My body feels like the battery is dead. I ache all over, I have headaches, I can’t eat, I can’t sleep — it’s like I have some weird disease that no doctor can find.”

• In reality, this is a full-blown depressive episode, but the brain uses the body as the primary stage instead of emotional language.

Somatic-Dominant Anxiety

• The patient does not feel subjectively “afraid,” but experiences palpitations, sweating, shortness of breath, shaking, and a sense of impending doom.
• All of this is the expression of an overactive panic–fear circuit, translated into bodily language.

Somatic-Dominant PTSD

• The stress from past traumatic events does not appear as classic flashbacks, but as physical symptoms — e.g., stomach pain, breathlessness, or full-body tension whenever the person hears a sound or smells something reminiscent of the trauma.

Somatic-Dominant Mixed Type

• Multiple bodily systems are involved together — for example, the digestive system, cardiovascular system, and autonomic nervous system — as if the entire body is “crying out all at once.”

---

3.4 Additional Clinical Assessment

Doctors will combine questionnaires and psychiatric interviews, such as:

• PHQ-15 (Patient Health Questionnaire – Somatic Symptom Scale)
• Health Anxiety Inventory (HAI)
• Somatic Symptom Scale-8 (SSS-8)

along with depression and anxiety scales such as PHQ-9 and GAD-7 to map the relationship between brain and body.

It is crucial to differentiate Somatic-Dominant presentations from:

• True physical illnesses such as hyperthyroidism, autoimmune disorders, or cardiac arrhythmias.
• Other psychiatric conditions such as Conversion Disorder, Factitious Disorder, or Malingering.

Once a thorough assessment is complete, only then can clinicians conclude whether this is a “Somatic-Dominant Type” tied to emotional or mood disturbance, or a genuine physical disease requiring specific medical treatment.

🧬4. Subtypes or Specifiers — Subgroups of Somatic-Dominant Type

For content and explanatory purposes, Somatic-Dominant Type can be broken down into the following subtypes:

4.1 Pain-Dominant Subtype

• Main symptom = pain (headache, back pain, muscle pain, joint pain), where:
• No clear pathology is found, or
• The severity of pain is disproportionately greater than what the physical condition would normally cause.
• Often linked to central sensitization — the brain lowers the threshold for pain perception, making the person feel pain more easily and intensely.

4.2 Autonomic-Dominant Subtype

Main symptoms include:

• Heart palpitations, racing heart.
• Easy sweating, hot flashes, or chills.
• Dizziness, lightheadedness, and fluctuating blood pressure.

This picture overlaps with GAD, Panic Disorder, or Dysautonomia that is closely tied to stress.

4.3 Gastrointestinal-Dominant Subtype

• Very similar to Irritable Bowel Syndrome (IBS) plus Functional Dyspepsia.
• Symptoms include stomach pain, abdominal tightness/bloating, diarrhea/constipation, acid reflux.
• Symptoms clearly worsen under stress, sleep deprivation, conflicts with significant others, etc.

4.4 Health-Anxiety Dominant Subtype

• Somatic symptoms are present, but fear of illness is more prominent than the symptoms themselves.
• Fear of cancer, heart attack, stroke, etc.
• Regardless of how many normal results they get, they remain unsatisfied and request even more tests.

🧠5. Brain & Neurobiology — Brain and Biological Mechanisms (Fully Expanded)

When we talk about Somatic-Dominant Type, at its core it is a story of:

“How the brain receives, interprets, and amplifies bodily signals beyond their real intensity.”

It is not faking, not “just overthinking,” but a brain network involving interoception, pain, and threat detection running in overdrive.

Let’s go circuit by circuit:

5.1 Insular Cortex & Anterior Cingulate Cortex (ACC) — The “Internal Sensing + Meaning-Making” System

Insula = the central hub for sensing “the internal state of the body.”

This brain region constantly listens to signals from the heart, lungs, gut, muscles, etc., such as:

• Is the heart beating faster?
• Is breathing shallow or rapid?
• Is the gut contracting strongly?
• Are muscles tense, tight, or burning anywhere?

In most people, the brain listens only to signals that are truly important — intense pain, bleeding, difficulty breathing, and so on.

But in Somatic-Dominant Type, Somatic Symptom Disorder, Health Anxiety, etc.:

• Multiple studies suggest that the insula is hyperactive.
• This means the brain “hears” small bodily signals too clearly, like having a microphone picking up every tiny sound in a house when normally it should filter most of them out.

Result = symptoms like:

• Feeling every heartbeat.
• Sensing every tiny spot of muscle tension.
• Noticing every minor irregularity in gut movement.

— even though other people “feel nothing at all” in those same bodily states.

---

Anterior Cingulate Cortex (ACC) = the system that attaches meaning and “danger labels” to those signals.

If we liken the insula to the microphone receiving bodily sounds,
→ then the ACC is the person listening and deciding:

• “Is this sound dangerous?”
• “Should I panic or stay calm?”

The ACC connects to emotion circuits (amygdala) and decision-making circuits (prefrontal cortex),
→ so it becomes the key structure that turns bodily signals into the subjective experience of suffering.

In Somatic-Dominant Type:

• The insula sends frequent, strong signals.
• The ACC tends to interpret them as “this is serious, we must pay close attention.”

Therefore, small sensations like mild chest tightness or a slightly faster heartbeat:

• Are interpreted by the brain as “very dangerous.”
• The person feels intense distress, pain, and fear — genuinely, not imagined.

In summary:

• Insula = “Something is happening in the body.”
• ACC = “And it might mean something is seriously wrong.”

When both systems are overactive together → the Somatic-Dominant picture becomes very clear.

---

5.2 Somatosensory Cortex & Pain Matrix — Why “Mild Pain” Feels “Unbearable”

Somatosensory Cortex

• This is where the brain’s body map resides.
• It translates signals of touch, pain, temperature, and body position from the skin, muscles, and joints.

Pain Matrix

• Not a single location but a network including:

• Somatosensory cortex
• Insula
• ACC
• Thalamus
• Prefrontal cortex

• Together, they determine:

• Where it hurts
• How much it hurts
• How much we should focus on it
• Whether we should flee, rest, or ask for help

In Somatic-Dominant Type / central sensitization:

• The pain matrix develops sensitization.
  → Nerves and brain circuits become “over-tuned”.

So:

• Mild signals that would normally be registered as “slightly annoying”
  → are experienced as “very painful / unbearable.”

It’s like:

• The volume knob for pain has been turned up by 2–3 levels.
• At the same time, the brain’s noise-cancelling system that usually filters out minor signals is working less effectively.

In real life:

• Patients feel pain, tightness, fatigue, and heaviness more intensely than test results can explain.
• Where is the error? → Not in them “lying,” but in the fact that:

“The brain’s sensory circuits have been recalibrated to a higher sensitivity than normal.”

---

5.3 Amygdala & Fear Circuit — The Alarm System That Loves Hitting the “Red Alert” Button

Amygdala

• The brain’s “threat detection center.”
• It constantly scans everything around and asks:
• “Is this dangerous?”
• “Should I be afraid?”

In health anxiety and Somatic-Dominant Type:

• The amygdala is often overactive — it labels nearly everything as “potentially dangerous.”

Fear Circuit

The amygdala connects to:

• Hypothalamus → activates the HPA axis → releases stress hormones.
• Brainstem → increases heart rate, speeds up breathing, and triggers sweating.
• Prefrontal Cortex → fuels repetitive threat-related thinking.

This means that even minor bodily changes, such as a slightly faster heartbeat from climbing stairs,

→ may be interpreted by the amygdala as “my heart might be failing.”
→ leading to mini-panic or intense health-related fear.

And importantly:

Conditioned Fear (Learning by Association)

• The first time:
• You’re in a crowded place → your heart races → you feel like you might faint.
• Even if nothing truly dangerous happened, the experience was terrifying.
• The brain immediately records:

“Racing heart + shortness of breath = nearly died / nearly had a serious medical event.”

• Next time, just feeling a slightly faster heartbeat (even from heat, caffeine, or normal exertion)
  → the amygdala slams the red button again.
  → the person feels like something terrible is happening all over again.
  → they begin to fear their own bodily sensations.

End result:

• The person starts avoiding various situations:

• No exercise.
• No heights.
• No crowded places.
• This pattern reinforces the belief in the brain that:

“See? We really are fragile and in danger; that’s why we must avoid these things.”

---

5.4 HPA Axis & Stress Hormones — When Chronic Stress Throws the Whole System Off

HPA Axis = Hypothalamus–Pituitary–Adrenal axis

• The hypothalamus detects stress.
• It sends signals to the pituitary gland.
• The pituitary tells the adrenal glands to release stress hormones like cortisol, adrenaline, and noradrenaline.

In chronic stress:

• Cortisol levels swing irregularly.
• The sympathetic nervous system (fight–flight) stays switched on.
• The parasympathetic nervous system (rest & digest) is underactive.

Physical consequences:

• Constant muscle tension → neck, shoulder, and back pain.
• Slightly elevated heart rate all the time → subjectively felt as palpitations.
• Gut function dysregulation → bloating, acid reflux, abnormal intestinal contractions (gut–brain axis).
• Immune system changes → chronic low-grade inflammation
  → resulting in unexplained aches, pains, and fatigue.

From a Somatic-Dominant Type perspective:

• Patients often view all this as signs of some “mysterious physical disease.”
• But from a brain–hormone view, it is:

“A stress circuit that has been left on for too long, pulling the whole body into a new abnormal baseline.”

Simply put:

• The body is not failing one organ at a time.
• The entire system has been shifted into a chronic stress mode, and the brain waves a sign saying, “This must be a serious disease,” making us believe it.

---

🧩6. Causes & Risk Factors — Causes and Risk Factors (Fully Expanded)

Somatic-Dominant Type does not arise from a single cause. It is the product of a combination of:

• Genetics
• Brain and nervous system characteristics
• Personality
• Life experiences
• Culture
• The modern social environment

Think of it like this:

“We are born with a particular kind of nervous system,
we grow up in a certain kind of home,
we go through particular life events,
and we live in an era flooded with health information and scary stories about disease.”

All of this combines, and the brain ends up choosing the body as its primary communication channel.

---

6.1 Biological Factors

1) Genetics and Nervous System Sensitivity

Families with a history of:

• Depression
• Anxiety
• Somatic Symptom Disorder
• IBS or chronic pain conditions

tend to show a higher prevalence of Somatic-Dominant patterns than the general population.

This means the brain and nervous system in such families are “more sensitive” by default.

Some people are simply born with a nervous system that is more sensitive to subtle sensations than others.

2) Pain Sensitivity

Some individuals naturally have a lower pain threshold.
→ What others can tolerate easily feels much more intense to them.

When combined with stress and catastrophic thinking,
→ minor symptoms become experiences of “pain so intense it feels unendurable.”

3) Neurotransmitter Imbalances

Neurotransmitters such as:

• Serotonin
• Norepinephrine
• Dopamine

are involved in both:

• Mood regulation
• Pain modulation

In depression, anxiety, and chronic pain, these systems are often dysregulated.

Certain SSRIs and SNRIs can help with both mood and somatic symptoms because they modulate these circuits.

4) HPA Axis & Autonomic Nervous System

People whose sympathetic system (fight–flight) is strong and whose parasympathetic system (rest–repair) is weak

→ will easily feel tense, have palpitations, and breathe shallowly.

When stress accumulates over time → this imbalance worsens → somatic symptoms become more prominent.

---

6.2 Psychological Factors

1) Personality Traits

People with high neuroticism tend to:

• Have easily shifting moods.
• Worry easily.
• Be more vulnerable to stress.

Combined with perfectionistic tendencies:

• Fear of making mistakes.
• Fear of losing control.

And in some, alexithymia — difficulty identifying and describing their own emotions:

→ They don’t know they’re sad, stressed, or angry.
→ So the body has to “speak instead” through pain, tightness, or pressure.

2) Cognitive Style

• Catastrophic thinking
• Chest pain = not “muscle tension,” but “I’m definitely having a heart attack.”
• Headache = not “stress or lack of sleep,” but “I must have a brain tumor.”
• Selective attention to bodily sensations
• Constantly focusing on bodily abnormalities all day.
• Noticing every little thing — slight redness of the skin, a brief flutter or “weird feeling,” etc.
• Confirmation bias
• Reading only stories of young people who died suddenly.
• Reading accounts of people having cancer without any clear symptoms.
• The more they read, the more they believe, “I’m probably like them too.”

3) Health-Anxious Coping Style

When stressed, other people might talk to someone, exercise, or rest.

But people in this group will:

• Listen intently to their body.
• Check symptoms.
• Count their pulse.
• Search for diseases online.

So the brain learns a pattern:

“Encounter stress = check the body.”

And each time it checks, it always finds “something” in the body → reinforcing the cycle again and again.

4) Past Experiences of Serious Illness

• Having been seriously ill or nearly died.
• Or witnessing close others suffer or die suddenly from disease.

The brain forms a powerful imprint:

“The body can betray at any moment; I must always stay on guard.”

From then on, every minor symptom is viewed through a highly fearful lens.

---

6.3 Social / Cultural Factors

1) Cultures That Forbid Emotional Weakness but Accept Physical Illness

In many societies (including Thailand), people are more accepting of phrases like:

• “My stomach hurts, I have headaches, I’m sick a lot”

than they are of:

• “I’m depressed / I’m anxious / I feel emotionally weak.”

As a result, the mind learns:

• “Talking about emotions = seen as weak.”
• “Talking about the body = receives empathy and care.”

Somatic-Dominant patterns become a safer language of the heart in such cultures.

2) Family Patterns

In families that give extra attention when a child is “sick”:

• Being sick = receiving love, gifts, and special care.
• Not being sick = being left more alone.

The child’s brain unconsciously learns:

“Being ill = a way to receive love and acceptance.”

Later in life, when stressed, the body automatically pulls this pattern back up.

3) Healthcare Systems and Past Experiences with Doctors

• If the health system normalizes “more tests = better care,”
  → health-anxious individuals feel they must investigate deeply, repeatedly, and thoroughly.

• If someone has previously had a serious disease missed by doctors,
  → they may strongly fear that, “Any doctor could be missing something important.”
  → leading them to distrust the word “normal” on test results.

• Conversely, if doctors say only, “You’re overthinking it,” without explaining brain–nervous system mechanisms,
  → patients feel misunderstood and invalidated, and often go doctor-shopping indefinitely.

---

6.4 Modern Environmental Factors

1) Internet / Dr. Google

Type “chest tightness” into a search bar → results range from acid reflux to sudden cardiac death.

People predisposed to health anxiety will:

• Focus on the worst-case scenarios.
• Imagine themselves as identical to the horror cases in the news.

So “a small physical symptom” → becomes “a full-blown death script” in their mind.

2) Social Media & Emotionally Charged Health News

• News about young people having heart attacks.
• Stories of young adults diagnosed with cancer without warning signs.
• Celebrities developing fatal illnesses with no obvious initial symptoms.

These stories go viral because they’re dramatic —
but the side effect is that many people start believing:

“Serious diseases can strike anytime, with no patterns at all.”

Those who already have a Somatic-Dominant predisposition are strongly triggered by such narratives.

3) Economic and Social Stress

• Insufficient income, lack of stability, strained relationships.

All of these add weight to the HPA axis,
→ keeping the nervous system in a state of chronic high alert.

When the brain has no safe channel to express emotional stress,
→ the body inevitably becomes the main stage on which that stress is expressed.

---

Summary of Sections 5 + 6 in Brief

• Section 5 (Brain & Neurobiology) explains:

How the brain receives, amplifies, and interprets bodily signals,
→ and why small bodily sensations can turn into major suffering.

• Section 6 (Causes & Risk Factors) explains:

Why some people have a brain–body system that “chooses to speak through symptoms”
instead of through words like “I’m stressed / I’m scared / I’m sad.”

Together, this helps us understand that:

Somatic-Dominant Type = the collaboration of a sensitive brain, suppressed emotions, life experiences, and a culture that dislikes hearing about feelings.
It is not weakness, not faking, and not “just overthinking.”

---

🧮7. Treatment & Management — Approaches to Care

The key principle is to “break out of the cycle of fearing illness → checking symptoms → increased fear,” without dismissively telling the person “you’re just overthinking it” (which usually makes things worse).

7.1 Medical Evaluation and Communication

• Perform appropriate physical examinations to avoid missing real disease.

• When results are normal, it is crucial to explain that:

• “The symptoms are real; the pain is real — but the brain is amplifying the signals.”
• Emphasize that this is a “disorder of the brain’s signal-processing system,” not “imagining things.”
• The goal must be framed as: reducing distress and improving daily functioning, not “finding 100% of the cause before anything can be done.”

---

7.2 Psychotherapy

CBT for Somatic Symptoms / Health Anxiety

• Identify and challenge catastrophic thought patterns.
• Train cognitive reappraisal = changing the way symptoms are interpreted.
• Conduct exposure with response prevention (e.g., reducing checking behaviors or unnecessary doctor visits).

Mindfulness-Based Therapy

• Teach the person to observe bodily sensations without judgment.
• Formerly: headache → “I must have a brain tumor.”
• Now: headache → “My body is sending some kind of signal, and I choose to take care of myself instead of panicking.”

Psychodynamic / Trauma-Focused Approaches

• In cases where somatization is tied to past conflicts or trauma.
• Gradually help the person see that unspoken emotions may be emerging through the body.

---

7.3 Medication

• If depression/anxiety is present, SSRIs / SNRIs have evidence for reducing both emotional symptoms and many somatic symptoms.

• In pain-dominant groups, some medications can help both mood and pain modulation (under medical supervision).

• Long-term use of strong painkillers or benzodiazepines should be avoided unless clearly necessary, due to risks of dependence and reinforcing illness behavior.

---

7.4 Self-Management

• Build basic routines: adequate sleep, light-to-moderate exercise, and balanced nutrition.

• Limit time spent “checking symptoms online” — for example, restrict to 10–15 minutes per day.

• Keep a log of symptoms alongside daily events → to detect patterns such as “stress = symptom flare-up.”

• Communicate with family/close others so they understand that “the symptoms are real, but not necessarily the catastrophic illnesses they fear,” in order to reduce unhelpful reinforcement.

---

📝8. Notes — Key Points

• People with Somatic-Dominant Type are not faking it, and they are not “weak.”
• Their pain and exhaustion are real — the issue lies in the brain/nervous system’s processing, not in moral strength.

• If you just say “You’re overthinking” →
• they often feel invalidated and dismissed, and become more “doctor-resistant” →
• leading them to seek out doctors who will do more scans and tests instead.

• Successful treatment usually requires:
• A teamwork approach among primary care physicians, psychiatrists/psychotherapists, and family.

• The goal is not “eliminate every single physical symptom 100%”, but rather to:
• Reduce distress from the symptoms.
• Restore the ability to live, work, and spend time with significant others as close to normal as possible.
