Heavy sweating may lead to the occurrence of potassium deficiency, as it is one of the causes of hypokalemia. Heavy sweating and extensive burns and prolonged hot work are among the causes of potassium ion loss through the body surface. In addition to this, other causes of hypokalemia include inadequate potassium intake or loss through the digestive tract, hyperthyroidism, renal potassium loss, familial periodic paralysis, drug-related potassium loss, and other medical procedures such as ascites drainage, dialysis, and abdominal drainage. Insufficient intake or loss of potassium through the gastrointestinal tract, which in turn includes under-eating or violent vomiting or diarrhea, causes a large loss of potassium through the gastrointestinal tract. Hyperthyroidism is one of the causes of hypokalemic periodic paralysis, while renal tubular acidosis and primary aldosteronism are the main diseases that lead to renal potassium loss, and drug-related potassium loss, such as dihydrocotrimoxazole and tachyphylaxis, can cause hypokalemia.
