What is a common presentation of metabolic alkalosis due to vomiting?

In cases of metabolic alkalosis resulting from vomiting, a common presentation is Boerhaave's syndrome. This condition is characterized by a rupture of the esophagus, which can occur due to extreme pressure changes, often related to forceful vomiting. The underlying mechanism involves a significant loss of gastric acid due to vomiting, leading to increased alkalinity in the body.

When vomiting occurs, the hydrochloric acid in the stomach is lost, which contributes to the development of metabolic alkalosis. Consequently, the body may react to this severe loss of gastric contents, leading to complications like Boerhaave's syndrome, where the esophageal wall is compromised and can lead to esophageal perforation.

The other options, such as acid reflux, abdominal pain, and pneumonia, may not specifically arise directly due to metabolic alkalosis but rather due to other mechanisms or underlying issues that are not as directly related to the vomiting-induced metabolic state. While abdominal pain can be associated with vomiting or other gastrointestinal complaints, it does not specifically indicate a complication linked to the metabolic alkalosis itself as Boerhaave's syndrome does.
