DiaphoresisDiaphoresis is an excessive sweating, or perspiration, which is typically due to shock, a medical emergency, or may be medically or artificially induced. It is also often associated with excessive sweating due to exercise or stress (emotional, physical, or mental).


The sweating in diaphoresis may be attributed either to normal or abnormal causes.

Normal causes

  • Eating spicy foods
  • Exercise or exertion
  • Fever
  • High-heat conditions
  • Menopause
  • Strong emotions
  • Trauma

Abnormal causes

  • Alcohol or withdrawal from it
  • Caffeine
  • Diabetes mellitus
  • Ectopic catecholamine
  • Gout
  • Heart attack (myocardial infarction)
  • Heart failure
  • Hyperthyroidism
  • Hypoglycemia (low blood sugar)
  • Infections
  • Lymphoma
  • Malaria
  • Obesity
  • Parkinson’s disease
  • Pheochromocytoma
  • Pregnancy
  • Rheumatoid arthritis
  • Serotonin syndrome
  • Shock
  • Tuberculosis


Generally, the underlying cause of the diaphoresis should be treated in order to reduce the sweating. This is particularly the case when the cause itself may be dangerous. In circumstances of normal perspiration, a treatment may not be necessary, however depending upon the cause, the underlying condition may require treatment.


In some cases, the cause of the sweating cannot be determined, but external causes that are environmental or pathological have been discarded as possibilities. When this occurs, the condition is known as hyperhidrosis. Essentially, hyperhidrosis is a condition involving abnormally increased sweating.

Night sweats

One common form of perspiration is night sweats. This itself may come from any one of a number of underlying causes.
