About Dr. Farkas →

Health anxiety — formerly called hypochondriasis, now classified under Illness Anxiety Disorder or Somatic Symptom Disorder in DSM-5-TR — involves persistent preoccupation with having or developing serious illness, despite limited or no actual physical symptoms (illness anxiety) or with disproportionate response to mild symptoms (somatic symptom disorder).

Health anxiety is highly treatable when properly recognized, but often persists for years because patients cycle through medical evaluations without addressing the anxiety itself.

DSM-5-TR Classifications

Illness Anxiety Disorder

Per DSM-5-TR criteria:

  • Preoccupation with having or acquiring serious illness
  • Somatic symptoms not present or mild; if medical condition present, preoccupation is excessive
  • High level of anxiety about health
  • Excessive health-related behaviors (checking) or maladaptive avoidance (avoiding medical care)
  • Illness preoccupation present at least 6 months
  • Not better explained by another mental disorder

Somatic Symptom Disorder

Per DSM-5-TR:

  • One or more somatic symptoms that are distressing or disrupt daily life
  • Excessive thoughts, feelings, or behaviors related to symptoms (disproportionate thoughts, persistently high anxiety, excessive time and energy devoted to symptoms)
  • Persistent symptomatic state, typically more than 6 months

Common Presentations

Checking behaviors

  • Frequent self-examination — checking skin for cancer, palpating lymph nodes, monitoring heart rate
  • Body scanning for symptoms
  • Mirror checking
  • Weighing repeatedly
  • Blood pressure monitoring

Information-seeking

  • Internet symptom searching (“cyberchondria”)
  • Medical literature reading
  • Symptom journaling
  • Multiple medical evaluations

Reassurance-seeking

  • Repeatedly asking family/friends
  • Multiple doctor visits
  • Seeking second/third/fourth opinions
  • Phone calls to medical providers

Avoidance patterns (subtype)

  • Avoiding medical appointments to avoid bad news
  • Avoiding situations that trigger health worry
  • Avoiding information about illnesses

The Reassurance Cycle

Health anxiety has a characteristic reinforcement cycle:

  1. Physical sensation or external trigger
  2. Anxious interpretation — could be serious
  3. Anxiety increases
  4. Checking, searching, or reassurance-seeking
  5. Temporary relief
  6. Anxiety returns — often heightened
  7. Cycle repeats with shorter intervals

Each reassurance-seeking event temporarily reduces anxiety but reinforces the pattern — making the next episode more likely and often more intense.

Comorbidities and Differential

Health anxiety frequently coexists with or must be distinguished from:

  • Generalized anxiety disorder (worry about many things, with health being one focus)
  • Obsessive-compulsive disorder (health-focused obsessions)
  • Panic disorder (which can produce significant health fears)
  • Major depression
  • Actual medical conditions causing anxiety

Evidence-Based Treatment

CBT

Cognitive Behavioral Therapy for health anxiety has the strongest evidence base. Components include:

  • Cognitive restructuring around catastrophic illness interpretations
  • Behavioral experiments testing predictions
  • Exposure to illness-related cues without checking/reassurance
  • Response prevention (reducing checking, searching, reassurance-seeking)
  • Identifying core beliefs about health vulnerability
  • Building tolerance of bodily sensation uncertainty

Medication

  • SSRIs — particularly when health anxiety coexists with depression or other anxiety conditions; off-label for health anxiety alone, but reasonable evidence base
  • SNRIs — similar role
  • Generally not first-line as monotherapy; CBT typically first

Coordination with primary care

Effective treatment typically involves coordination with primary care:

  • Limiting reassurance-providing evaluations
  • Structured rather than reactive medical care
  • Clear communication about what reassessment is appropriate vs. excessive
  • Avoiding unnecessary testing that perpetuates anxiety cycle

The Problem

Endless medical cycle

Patients with health anxiety often cycle through medical evaluations and testing for years — addressing symptoms rather than the underlying anxiety.

Common Questions About Health Anxiety

What if I actually have something wrong?

Health anxiety doesn’t mean you don’t have real medical conditions — many patients with health anxiety also have actual medical issues. Treatment doesn’t ignore real conditions; it addresses the disproportionate anxiety response that produces suffering and impairment.

Should I stop seeing my doctor?

No — but structured medical care typically works better than reactive care driven by anxiety episodes. Coordinated approach can establish appropriate evaluation patterns.

Will reading less help?

Reducing Internet symptom searching is often part of treatment — but typically more effectively through structured behavioral approach than willpower alone. See our related articles on anxiety disorders and generalized anxiety.

Do I need medication?

Not necessarily. CBT alone often works well for health anxiety. Medication can help when depression or other anxiety conditions coexist.
