Metabolic alkalosis can be caused by repeated vomiting, [2] resulting in a loss of hydrochloric acid in the stomach contents. Severe dehydration, and the consumption of alkali, [3] are other causes. It can also be caused by administration of diuretics [2] and endocrine disorders such as Cushing's syndrome.
Low potassium is caused by increased excretion of potassium, decreased consumption of potassium rich foods, movement of potassium into the cells, or certain endocrine diseases. [3] Excretion is the most common cause of hypokalemia and can be caused by diuretic use, metabolic acidosis, diabetic ketoacidosis, hyperaldosteronism, and renal tubular ...
Metabolic alkalosis is an acid-base disorder in which the pH of tissue is elevated beyond the normal range (7.35–7.45). This is the result of decreased hydrogen ion concentration, leading to increased bicarbonate (HCO − 3), or alternatively a direct result of increased bicarbonate concentrations.
Diagnosis of contraction alkalosis is made by correlating laboratory data with clinical history and examination. Metabolic alkalosis in the presence of decreased effective circulatory volume, loop diuretic use, or other causes of intravascular depletion such as profound diarrhea should raise suspicion for contraction alkalosis as a likely etiology in the absence of other causes.
Blood biochemistry should be monitored regularly until it is stable. Although clinical trials are lacking in patients other than those admitted to intensive care, it is commonly recommended that energy intake should remain lower than that normally required for the first 3–5 days of treatment of refeeding syndrome for all patients.

Milk-alkali syndrome (MAS), also referred to as calcium-alkali syndrome, is the third most common cause of elevated blood calcium levels (hypercalcemia). [2] [3] Milk-alkali syndrome is characterized by hypercalcemia, metabolic alkalosis, and acute kidney injury.
The clinical findings characteristic of Bartter syndrome is hypokalemia, metabolic alkalosis, and normal to low blood pressure. These findings may also be caused by other conditions, which may cause confusion. When diagnosing a Bartter's syndrome, the following conditions must be ruled out as possible causes of the symptomatology: [citation needed]
Pseudohyperaldosteronism (also pseudoaldosteronism) is a medical condition which mimics the effects of elevated aldosterone (hyperaldosteronism) by presenting with high blood pressure, low blood potassium levels (hypokalemia), metabolic alkalosis, and low levels of plasma renin activity (PRA).
