|This is due to excessive sweating in an atmosphere of high
temperature when there is both fluid and salt depletion and
the subject has not taken enough fluid or salt to make good
the loss. Heat exhaustion may be of two types:
Heat exhaustion due to loss of salts (heat cramps):
This is characterized by weakness, headache, giddiness, nausea,
vomiting, cramps in the legs and irritability. Gradually the
BP falls and the patient becomes pale. The pulse becomes weak
and quick and the patient collapses. Chloride and sodium levels
and the urinary choloride levels are very low.
Andydrotic heat exhaustion:
This is seen in association with prickly heat. The patient
feels extremely weak, becomes irritable and the BP is low.
A little effort may cause the patient to collapse. There
may be localized sweating in the axilla, hands and forehead.
This condition may lead to heat stroke.
Keep the patient in a cool environment. Water replacement
may be done by giving adequate water to drink. Bryonia, Glonine
china, Natrum mur and Avena sat are good homoeopathic medicines
