Table 2 Causes of hypothermia (from [10])

From: Association between thymoma and persistent hypothermia: a case report

Likely Mechanism Cause of Hypothermia
Decreased heat production Hypothyroidism
  Hypopituitarism
  Hypoadrenalism
  Malnutrition
  Hypoglycemia
  Neuromuscular inefficiency
Increased heat loss Accidental (exposure to cold ambient temperature)
  Drug-induced vasodilatation
  Burns
  Exfoliative dermatitis
  Severe psoriasis
  Iatrogenic (e.g. treatment of pyrexia, large volume infusions of non-warmed fluid)
Impaired thermoregulation Central nervous system trauma
  Acute spinal cord transection
  Stroke/Intracranial haemorrhage
  Central nervous system tumour
  Parkinson's disease
  Multiple sclerosis
  Wernicke's disease
Combination of mechanisms Sepsis
  Ethanol intoxication
  Hypnotics
  Phenothiazines
