Metabolic alkalosis

Metabolic Alkalosis

Metabolic alkalosis (/mɪˈtæbəlɪk ælkəˈloʊsɪs/) is a metabolic disorder that occurs when the body's pH level in the blood becomes elevated beyond the normal range (7.35-7.45), due to an excess of bicarbonate (HCO3-) or a loss of hydrogen ions (H+).

Etymology

The term "metabolic alkalosis" is derived from three words: "metabolic," from the Greek metabole meaning change; "alkalosis," from the Arabic al-qaliy meaning alkali, and the Greek -osis meaning condition or disorder.

Causes

Metabolic alkalosis can be caused by prolonged vomiting, which leads to a loss of hydrogen ions, or by the ingestion of too much bicarbonate from antacids. Other causes include diuretic use, hyperaldosteronism, and Cushing's syndrome.

Symptoms

Symptoms of metabolic alkalosis can include muscle twitching, hand tremor, nausea, vomiting, numbness, and tingling sensation in the extremities or around the mouth.

Treatment

Treatment of metabolic alkalosis involves correcting the underlying cause. This may involve stopping the use of diuretics, treating the underlying disease, or replacing lost electrolytes.
