What is contraction alkalosis associated with?

Contraction alkalosis is primarily associated with a condition where there is a loss of fluid from the body, which leads to a relative increase in the concentration of bicarbonate in the blood. This is most commonly observed in situations where there is significant fluid loss, particularly through vomiting. In the case of induced vomiting, such as that which occurs in bulimia, the stomach acid (hydrochloric acid) is expelled, leading to a decrease in hydrogen ions and thus causing an alkalotic state. The body also compensates for the loss of volume by concentrating bicarbonate, further exacerbating the alkalosis.

In contrast, while conditions like congestive heart failure, dehydration, and diabetes mellitus can impact fluid and electrolyte balance, they are not specifically linked to the mechanisms that define contraction alkalosis in the same way that induced vomiting is. Congestive heart failure typically leads to fluid retention rather than loss, dehydration can lead to a decrease in bicarbonate but does not inherently cause alkalosis. Diabetes mellitus can lead to various disturbances in acid-base balance, but it does not have a direct association with contraction alkalosis as seen with vomiting. This highlights the unique connection that induced vomiting has with contraction alkalosis through the loss of stomach acid and subsequent changes in bicarbon
