Common symptoms of hypothyroidism include fatigue, sensitivity to cold, constipation, dry skin, weight gain, puffy face, hoarseness, muscle weakness, elevated cholesterol, muscle aches, tenderness, stiffness, joint pain, swelling, irregular or heavy menstrual periods in women, thinning hair, depression, impaired memory, and slowed heart rate (Mayo Clinic, 2018).

Clinical manifestations:

  • Fatigue and lethargy
  • Weight gain
  • Complaints of cold hands and feet
  • Temperature and pulse become subnormal; patient cannot tolerate cold and desires increased room temperature
  • Reduced attention span; impaired short-term memory
  • Severe constipation
  • Generalized appearance of thick, puffy skin; subcutaneous swelling in hands, feet, and eyelids
  • Thinning hair, loss of the lateral one-third of eyebrow
  • Menorrhagia or amenorrhea
  • Neurologic signs include polyneuropathy, cerebellar ataxia, muscle aches or weakness, clumsiness, prolonged deep tendon reflexes
  • Hyperlipoproteinemia and hypercholesterolemia
  • Enlarged heart on chest x-ray
  • Increased susceptibility to all hypnotic and sedative drugs and anesthetic agents
