Why do people with ketoacidosis hyperventilate?

People with ketoacidosis hyperventilate primarily to compensate for the metabolic acidosis that occurs due to elevated ketone bodies in the blood. This condition leads to an increase in carbon dioxide (CO2) levels, which the body attempts to expel through rapid breathing, or hyperventilation. By doing so, the body aims to restore normal blood pH levels and reduce acidity. This respiratory response is part of the body's effort to maintain homeostasis in the face of significant metabolic disturbances.
