Verified step by step guidance

Understand the concept of acid-base balance: The body maintains a delicate balance between acids and bases, primarily through the bicarbonate buffer system, respiratory system, and renal system.

Identify the cause of the imbalance: Vomiting leads to the loss of stomach acid (hydrochloric acid), which is a significant source of hydrogen ions (H+). This loss reduces the acidity in the body.

Determine the type of acid-base imbalance: Since vomiting results in a loss of acid, the body becomes more alkaline. This condition is known as alkalosis.

Differentiate between metabolic and respiratory causes: Metabolic alkalosis is caused by an increase in bicarbonate or a loss of hydrogen ions, while respiratory alkalosis is due to hyperventilation leading to a decrease in carbon dioxide (CO2). Since vomiting involves the loss of hydrogen ions, it is a metabolic process.

Conclude the type of imbalance: Based on the understanding that vomiting leads to a loss of hydrogen ions and an increase in bicarbonate, the acid-base imbalance resulting from vomiting is metabolic alkalosis.
