Somatic Symptom & Related Disorders: A Clear & Simple Guide
Do you experience strong, persistent body symptoms—like pain, fatigue, or dizziness—but medical tests find nothing? It's incredibly frustrating and even scary.
Today, we'll explain exactly why this happens. We'll explore how mind and body constantly communicate. You'll learn why your distress is absolutely real. Most importantly, you'll discover treatments that actually help.
Real symptoms • Real distress • Real help
You are not imagining it. There is a path forward.

Clear blueprint for evaluation and evidence-based interventions

The Big Idea: These symptoms are not faked. Your body's alarm system has become overly sensitive. It's ringing when there's no fire. The good news? We can recalibrate that alarm.
The Mind-Body Connection Made Simple
Think of Your Body as a High-Performance Car
Sometimes, the alarm system gets set too high. A small bump sets it off, blaring loudly even when there's no actual damage.
Your brain constantly predicts and scans your body. When you're stressed, your brain turns up the scanner's sensitivity. Normal sensations suddenly feel loud, dangerous, and alarming.
The Cycle That Keeps You Stuck
Body Sensation
A normal feeling gets noticed
Scary Thought
"What if it's a heart attack?"
Anxiety Rises
Fear creates more tension
Increased Focus
You monitor your body more
Stronger Sensation
The feeling intensifies
This creates a loop that reinforces itself. Our goal in treatment is to break this loop, not just chase individual symptoms.
Quick Quiz: Are these symptoms faked? Answer: No. The distress is absolutely real; the body's alarm system is just too sensitive.
Somatic Symptom Disorder (SSD)
What Is SSD?
To be diagnosed with SSD, a person must have at least one bothersome physical symptom disrupting daily life. The key is their reaction: excessive thoughts, feelings, or behaviors about that symptom. This pattern must last at least 6 months.
Physical Symptom
At least one bothersome symptom present
Excessive Reaction
Disproportionate thoughts, feelings, or behaviors
Duration
Symptoms persist for 6 months or longer
Asha's Story
Asha has persistent chest pain. She's had multiple ECGs, all normal. But she's terrified she's missing something.
She checks her pulse constantly. She avoids stairs for fear of straining her heart. She spends hours Googling symptoms every night.
Her anxiety is skyrocketing. Her life is shrinking because of it.
Why It Persists
1
Sensation
Chest tightness noticed
2
Catastrophic Thought
"I'm having a heart attack"
3
Anxiety
Fear and panic increase
4
Checking
Pulse checked repeatedly
5
Short Relief
Brief calm, then cycle repeats
When Asha checks her pulse and it's normal, she gets temporary relief. But her brain learns that checking is the only way to feel safe. The urge to check gets stronger, and the alarm gets louder.
Treatment for SSD
Psychoeducation
Explain the "sensitive alarm" model. Validate that pain is real, even without disease.
Cognitive Behavioral Therapy
Challenge scary thoughts. Reduce checking behaviors. Use graded activity to slowly increase function.
Regular Visits
See one primary doctor regularly. Build trust. Reduce panic visits.
Medications
SSRIs or SNRIs can help with anxiety and depression.
Lifestyle Changes
Good sleep, gentle exercise, stress management are foundational.
Quick Quiz: Name two CBT tools for SSD. Answer: Reducing checking behaviors and using graded activity.
Illness Anxiety Disorder (IAD)
What Is IAD?
IAD is what used to be called hypochondriasis. The key difference from SSD: the person has no or very minimal physical symptoms. Their primary problem is high anxiety about having or getting a serious illness. This must last at least 6 months.
Care-Seeking Type
Constantly seeks medical tests and reassurance from doctors
Care-Avoidant Type
So terrified they avoid doctors altogether
Why It Happens: The Availability Bias
News stories and social media make rare diseases feel incredibly common. This is called the availability bias. Normal sensations are misinterpreted as danger.
1
News Story
Celebrity dies from rare cancer
2
Normal Sensation
Mild tension headache occurs
3
Misinterpretation
"This must be cancer"
4
Panic Spiral
Repeated calls for reassurance
Rohan's Story

Rohan reads a news story about a celebrity who died young from rare cancer. Suddenly, his mild, normal tension headache feels like a death sentence. He spirals into panic and starts calling clinics repeatedly for reassurance.
Treatment for IAD
1
Behavioral Experiments
Wait 24 hours before calling a doctor. See if anxiety naturally decreases.
2
Reassurance Limits
Create a contract: ask "do I look okay?" once daily, not ten times.
3
Attention Training
Shift focus outward into the world, not inward scanning the body.
4
Accepting Uncertainty
Learn to live with unavoidable small health uncertainties.
5
Media Diet
Limit time reading health news or watching medical dramas.
Quick Quiz: What bias makes rare diseases feel common because we see them in the news? Answer: The availability bias.
Conversion Disorder (Functional Neurological Disorder)
What Is Conversion Disorder?
Also known as Functional Neurological Disorder (FND), this involves real neurological symptoms. These include weakness, paralysis, blindness, or non-epileptic seizures. But symptoms don't match recognized structural disease patterns.
It's a Functional Problem
Software issue, not hardware damage. The brain is capable, but signals get scrambled.
It's Real
These are involuntary, genuine experiences. Not faked or imagined.
It's Reversible
With proper treatment and retraining, symptoms can improve significantly.
How It Works
Think of it as an override. Attention, expectation, and the brain's predictive coding can block normal motor or sensory signals.
Stress or past trauma can make this system more likely to misfire. It often involves a degree of dissociation.
Clinical Clues
Doctors look for specific "positive signs," not just absence of disease.
  • Hoover's sign: "Weak" leg finds strength when other leg is active
  • Tremor variability: Changes rhythm when person is distracted
  • Seizure features: Eyes tightly closed, steady breathing during episode
Fatima's Story
Fatima experiences sudden episodes where she collapses and shakes. During these episodes, her EEG is normal. Her eyes are tightly closed, unlike most epileptic seizures. Her breathing is steady. These are clues pointing to non-epileptic, functional seizures.
Treatment for Conversion Disorder
Positive Explanation First
"You have a software problem, not hardware. Your brain is okay. These symptoms are reversible."
Physiotherapy Retraining
Exercises that shift attention away from symptom. Walking while counting backward. Tossing a ball.
Cognitive Behavioral Therapy
Reduce focus on symptoms. Manage underlying stress or trauma.
Treat Comorbidities
Address any PTSD, depression, or anxiety disorders.
Quick Quiz: What is the key message for patients with conversion symptoms? Answer: It's a functional problem, not structural damage. It is real and reversible.
Psychological Factors Affecting Medical Conditions
When Stress Makes Real Illness Worse
This category is exactly what it sounds like. A person has a real, diagnosed medical illness—like asthma or diabetes.
But psychological factors are making it significantly worse. These include severe stress, denial, or poor coping strategies.
Example: Asthma
Severe stress triggers more frequent attacks. Poor inhaler adherence due to denial worsens control.
Example: Diabetes
Anxiety about checking blood sugar leads to avoidance. Blood sugar control deteriorates rapidly.
Example: Heart Disease
Depression reduces medication adherence. Stress increases cardiac events significantly.
Treatment Approach
Treatment involves CBT for stress management. We work to improve medication adherence. Problem-solving skills are taught to address barriers to care.
Factitious Disorder vs. Malingering
Let's clear up a common confusion: people who intentionally fake symptoms. These are fundamentally different from the disorders we've discussed.
Factitious Disorder
Intentional Faking
Person deliberately produces or fakes symptoms
Internal Motivation
Wants to assume the "sick role" and receive care and attention
Mental Disorder
Recognized as a psychiatric condition requiring treatment

Warning: Factitious Disorder Imposed on Another (like on a child) is severe abuse. It requires immediate safeguarding action.
Malingering
Intentional Faking
Person deliberately fakes symptoms
External Motivation
Wants money, drugs, to avoid work or military duty
Not a Mental Disorder
Considered a behavior, not a psychiatric condition
Quick Quiz: Internal gain vs. external gain. Which belongs to which? Answer: Internal gain = Factitious Disorder. External gain = Malingering.
Assessment Blueprint & Treatment Summary
The Assessment Blueprint
When assessing these disorders, follow this structured approach:
01
Validate
Start by saying, "I know your pain is real."
02
Review Medical History
Ensure medical causes have been reasonably ruled out. Avoid endless re-testing.
03
Map the Cycle
Help them see the link between sensations, thoughts, and behaviors.
04
Screen Comorbidities
Check for anxiety, depression, trauma, and substance use.
05
Assess Function
How is this affecting work, school, relationships, and sleep?
06
Risk Assessment
Always check for self-harm or unsafe avoidance behaviors.
Treatment Framework
Education First
Psychoeducation is the first intervention. Explain the mind-body connection clearly.
CBT Gold Standard
Break the cycle of checking and avoidance. Challenge catastrophic thoughts.
Physiotherapy
Crucial for functional motor symptoms. Attention-shifting exercises work.
Medications
SSRIs or SNRIs can help with comorbid anxiety or depression.
One Lead Clinician
Coordinate care to prevent conflicting messages and repeated testing.
