    1. Acute edema related to heat exposure
  3. Epidemiology
    1. More common in older patients
  4. Pathophysiology
    1. In warm environments, body shunts warm blood to periphery via peripheral vasodilation
    2. Increased peripheral fluid results in microvascular transudate
    3. Despite edema, patients are typically intravascularly volume depleted
    4. May be provoked by rapid transition from cold to hot environments
  5. Symptoms
    1. Abdominal bloating
  6. Signs
    1. Weight gain up to 5 kg over several days
    2. Distribution
      1. Ankle edema (most common)

  7. Differential Diagnosis
    1. See Edema
  8. Labs
    1. Serum Sodium decreased (Hyponatremia)
  9. Management
    1. Move to cooler environment
    2. Elevate extremities
    3. Do NOT administer Diuretics (not helpful and potentially harmful in a volume depleted patient)
  10. Course
    1. Onset within 48 hours of arriving in warm climate
    2. Resolves with acclimatization diuresis in a few days
