What is Alkalosis

Excessive alkalinity (elevated pH) of body fluids caused by either an accumulation of alkaline substances or a reduction in ACIDS. Alkalosis is thus more general than ALKALEMIA (alkaline blood). Respiratory alkalosis occurs with hyperventilation, aspirin poisoning, abnormal brain function, or inadequate oxygen supply, as may occur during exertion at high altitudes. Metabolic alkalosis occurs with severe VOMITING due to losses of hydrogen ions and chloride ions (STOMACH ACID); losses of POTASSIUM due to diuretic therapy; and ingestion of BAKING SODA (or other alkaline substances). Symptoms of both types of alkalosis include shallow breathing, a tingling sensation at fingertips and toes, muscular cramps, and convulsions. Like prolonged ACIDOSIS, alkalosis requires medical intervention.
