Metabolic Alkalosis.

Metabolic alkalosis is one of the four cardinal acid-base disorders and perhaps the least well understood by students. Taking a mechanistic approach to etiologies and management can be very helpful in such cases. Particularly, one should focus on the factors that generate the alkalosis (source of fluid loss and composition, less commonly alkali administration) and the factors (extracellular fluid volume status, hormonal systems) that maintain the abnormality.
