Frequently asked questions about Heat Stroke

1) Which doctor should I consult for heat stroke?

You should consult a general physician for treating heat stroke

2) What are heat syndromes?

Heat syndromes are a group of six conditions, which occur on exposure to high environmental temperatures. They are:
  • Heat Stroke
  • Heat exhaustion type1
  • Heat exhaustion type2
  • Water depletion heat exhaustion
  • Heat syncope
  • Heat cramps

Heat exhaustion type 1: This is also called salt deficiency heat exhaustion. The condition occurs due to prolonged sweating. It occurs as a result of loss of salt from the body without sufficient replacement. The features are tiredness, nausea, vomiting, giddiness, cramps and dehydration. It can lead to shock if it is left untreated. Patients can be treated by bringing the salt-water ratio and blood volume back to normal.

Heat exhaustion type 2: This occurs after months of chronic exposure to hot and humid environment. The features are early tiredness, headaches, giddiness, and boils on the skin especially around the arms and the trunk, increased heart rate and a sudden increase in the body temperature to 102F. Asking the patient to rest in a cool room is generally enough to relieve the symptoms.

Heat syncope: This is also known as exercise induced heat exhaustion or heat collapse. This condition occurs in individuals who are not acclimatized to the heat. It manifests as syncope, giddiness and tiredness. Recovery results when the patient is placed in cool surroundings and steps are taken to restore the salt-water balance in the body.

Water depletion heat exhaustion: This condition results in prolonged sweating followed by inadequate replacement of water. There is pronounced thirst, tiredness, and reduced amount of urine production, fever, delirium and coma. A cool surrounding with adequate replacement of water helps the patient to recover.

Heat cramps: It is characterized by the development of painful muscular cramps with heavy sweating and salt depletion. Salt replacement helps to recover the patient from this condition.
