  • E89.0 Post-procedural hypothyroidism


  • Autoimmune disease
  • Thyroid gland is gradually destroyed
  • Results in hypothyroidism
  • Enlargement of the thyroid

Essentials of Diagnosis

  • Thyroid gland becomes lobulated
  • Decreased activity tolerance
  • Sensitivity to cold
  • Abnormal thyroid function tests
  • Often misdiagnosed as fibromyalgia and depression

General Considerations

  • Diagnosis for more occult problems may take time and require intensive medical diagnostic testing
  • May cause pathology in multiple organ systems
    • Cardiovascular: heart, peripheral circulation, blood pressure
    • Integumentary
  • May result in secondary problems indicating the need for PT intervention depending on severity
    • Aerobic capacity and muscle endurance impairment
    • Sarcopenia
    • Weakness/impaired muscle performance
    • Musculoskeletal problems
    • Neuromuscular problems
    • Weight gain, indicating the need for physical therapy intervention depending on severity
  • Gradual onset
  • Hyperlipidemia


  • Can occur in anyone
  • Higher incidence in women, primarily middle aged
  • Tends to run in families
  • Between 0.1% and 5% of all adults

Signs and Symptoms

Functional Implications

  • Severe symptoms such as immediacy of need to urinate may be disabling, resulting in the inability to leave home
  • Inability to afford testing and medications
  • Fatigue
  • Drowsiness
  • Infertility
  • Miscarriage
  • Heart disease
  • Decreased sex drive
  • Increasing weight with inability to exercise or move well
  • Sarcopenia resulting in
    • Weakness
    • Muscle mass loss
    • Inability to ambulate or perform self-care
    • Aerobic capacity limitation secondary to inactivity
  • Decreased exercise tolerance
  • Sleep disturbances
  • Changes in lifestyle
  • Eating disorders
  • Anxiety and depression
  • Can lead to problems with liver
  • Limitations in ADLs or IADLs
  • Systemic infection
  • Skin lesions from dryness
  • Neuropathy, increased risk for falls
  • Vision impairment, most often retinal
  • Prone to infections such as bacterial in the skin, fungal, urinary tract infections (UTIs), kidney
  • Potential for ...
