Case 2: Generalized Anxiety with Somatic Symptoms

Patient Presentation

Demographics: 31-year-old male financial analyst

Chief Complaint: "Something is seriously wrong with my heart — I keep having chest pain and palpitations, and I'm convinced I'm going to have a heart attack."

History of Present Illness: Mr. Kowalski presents to his primary care physician for the fourth time in six months with concerns about his heart. He reports recurrent episodes of chest tightness, palpitations, shortness of breath, dizziness, and diaphoresis occurring 3-5 times per week, each lasting 20-45 minutes. He has visited the emergency department twice, where cardiac workup was negative both times. Despite reassurance, he remains convinced that something is being missed.

Between these acute episodes, he describes persistent worry that dominates his waking hours. He worries about his health (convinced he will develop his father's heart disease), his job performance (despite being recently promoted), his relationship (fears his girlfriend will leave him), and global events (financial markets, climate change, geopolitical conflict). He describes his worry as uncontrollable — "my mind is like a computer running 100 tabs." He reports difficulty concentrating at work, irritability that has caused conflict with his girlfriend, and muscle tension causing chronic neck and back pain.

He has developed extensive safety behaviors: he checks his pulse 20-30 times daily using a smartwatch, avoids exercise for fear of cardiac events (he was previously a recreational cyclist), avoids caffeine, and has started sleeping with a pulse oximeter. He has researched his symptoms extensively online, which invariably increases his anxiety. He has missed 8 work days in the past 3 months due to his symptoms.

Past Medical History:

• Mitral valve prolapse (incidental finding on echocardiogram during ED visit; trivial regurgitation, hemodynamically insignificant)
• No other medical conditions
• No psychiatric history (no prior treatment for anxiety or depression)

Medications:

• None prescribed
• Self-medicating with OTC antihistamines for sleep (diphenhydramine 50 mg nightly)
• Magnesium supplement
• CBD oil (self-directed)

Social History:

• Financial analyst at investment bank; high-pressure work environment
• In a 2-year relationship; partner is supportive but "exhausted" by reassurance-seeking
• Non-smoker; quit caffeine 3 months ago (anxiety management)
• Former recreational cyclist (stopped 6 months ago)
• No alcohol (stopped due to health anxiety)
• No recreational drugs
• Family of origin: grew up with an "anxious mother who always thought something was wrong"

• Affect: Anxious, wide-eyed, hypervigilant
• Thought process: Linear but perseverative on somatic symptoms
• Thought content: No suicidal or homicidal ideation; health-focused catastrophic cognitions
• Insight: Partial — "I know logically my heart is fine, but I can't make my body believe it"

Workup and Results

Validated Assessment Tools:

Laboratory Studies:

Prior Cardiac Workup (from ED visits and cardiology):

• ECG x3: Normal sinus rhythm; no ST changes; no arrhythmia
• Troponin x2: Negative
• Echocardiogram: Mitral valve prolapse with trivial regurgitation; normal LV function (EF 65%); no structural abnormality
• Exercise stress test: Negative for ischemia; normal chronotropic response; no arrhythmia; excellent functional capacity (13.2 METs)
• 14-day Holter monitor: Sinus rhythm throughout; occasional PACs (< 1%); no sustained arrhythmia
• Coronary calcium score: 0 Agatston units

Clinical Image

Cognitive-behavioral model of health anxiety and somatic symptom amplification: normal bodily sensations (e.g., benign palpitations from MVP) are catastrophically misinterpreted, triggering anxiety, which produces additional somatic symptoms (tachycardia, chest tightness, dyspnea), reinforcing the catastrophic belief in a self-perpetuating cycle maintained by safety behaviors (pulse-checking, ED visits, avoidance).

Diagnosis

Generalized Anxiety Disorder with Prominent Somatic Symptoms and Health Anxiety (ICD-10: F41.1, F45.21)

Key Diagnostic Criteria:

• Excessive, uncontrollable worry about multiple domains (health, work, relationships, world events) for > 6 months
• Six of six associated features present: restlessness, fatigue, concentration difficulty, irritability, muscle tension, sleep disturbance
• High somatic symptom burden (PHQ-15: 16) with health-focused catastrophic cognitions
• Significant functional impairment (missed work, relationship strain, activity avoidance)
• Exhaustive medical workup excludes organic cardiac pathology
• Anxiety sensitivity (fear of anxiety sensations themselves) perpetuating the cycle
• Family history supporting genetic vulnerability (mother with GAD, brother with panic disorder)

Treatment Plan

1. Psychoeducation (Foundation): Explain the cognitive-behavioral model of somatic symptom amplification; validate that symptoms are REAL (not "imagined") but are generated by the nervous system in response to anxiety, not by cardiac disease; draw the vicious cycle diagram with the patient
2. Cognitive Behavioral Therapy (First-Line): Weekly CBT sessions with a therapist experienced in health anxiety; specific techniques: cognitive restructuring of catastrophic health beliefs, interoceptive exposure (deliberately inducing feared sensations — e.g., hyperventilation, exercise, caffeine), behavioral experiments (exercise without checking pulse), gradual reduction of safety behaviors (smartwatch pulse-checking, ED visits, reassurance-seeking)
3. Safety Behavior Reduction Protocol: Collaboratively reduce pulse-checking from 30x/day to set check-in times (3x/day), then eliminate; remove pulse oximeter from bedroom; establish a rule of "no Googling symptoms"
4. SSRI Medication: Initiate sertraline 25 mg daily (start low — patients with anxiety sensitivity are prone to somatic side effects and may discontinue prematurely); titrate to 50-100 mg over 4 weeks; counsel that initial worsening of anxiety is possible and expected for 1-2 weeks before improvement; target dose 100-200 mg
5. Exercise Reintroduction: Graded reintroduction of cycling with interoceptive exposure framework — the physical sensations of exercise (elevated HR, sweating, breathlessness) serve as therapeutic exposure to feared sensations; start with 15 minutes at low intensity; this is both exercise AND therapy
6. Mindfulness Training: Body scan meditation to develop non-reactive awareness of bodily sensations; mindfulness-based cognitive therapy (MBCT) techniques to observe thoughts without engagement; 10 minutes daily guided practice initially
7. Discontinue Diphenhydramine: Chronic use of anticholinergic antihistamines for sleep is associated with cognitive impairment and rebound insomnia; transition to sleep hygiene practices and CBT-I if insomnia persists
8. Partner Involvement: Invite partner to a session to provide psychoeducation; teach partner how to avoid inadvertent reassurance that maintains the anxiety cycle while remaining supportive
9. Follow-up: Biweekly psychiatric visits for medication management; weekly CBT; reassess GAD-7 and PHQ-15 monthly; target: GAD-7 < 5, return to full work functioning, resumption of exercise

Key Learning Points

• Generalized anxiety disorder (GAD) has the highest rate of somatic symptom presentation of all anxiety disorders — over 70% of GAD patients present initially to medical settings rather than mental health settings, and the average patient undergoes extensive (and expensive) medical workup before receiving a psychiatric diagnosis
• Health anxiety exists on a spectrum and is best understood through the cognitive-behavioral model: normal bodily sensations are catastrophically misinterpreted, generating anxiety, which produces additional somatic symptoms, which are further misinterpreted — creating a self-perpetuating cycle
• Safety behaviors (reassurance-seeking, body-checking, repeated medical visits, avoidance of activities) provide short-term relief but maintain anxiety long-term by preventing the patient from learning that feared outcomes do not occur
• Interoceptive exposure — deliberately inducing feared bodily sensations in a therapeutic context — is the most effective behavioral intervention for patients with high anxiety sensitivity and somatic-focused anxiety
• Mitral valve prolapse (MVP) is found in 2-3% of the general population and is almost always hemodynamically insignificant; however, it is diagnosed more frequently in anxiety patients due to increased medical evaluation, and the benign palpitations it can cause become a focus for catastrophic misinterpretation
