Metabolic acidosis is a medical condition characterized by an imbalance in the body's acid-base balance, leading to an increase in acidity. This occurs when the body produces too much acid or when the kidneys are unable to remove enough acid from the body. Common causes include diabetes, kidney disease, and severe dehydration. Symptoms of metabolic acidosis can include fatigue, confusion, and rapid breathing. Diagnosis typically involves blood tests to measure the levels of bicarbonate and pH. Treatment focuses on addressing the underlying cause and may involve administering bicarbonate or other medications to restore balance.
