Acidosis - metabolicDefinition Return to top
Metabolic acidosis is a disturbance of the body acid-base balance in which there is excessive acidity of the blood. Metabolic acidosis can occur as a result of many different conditions, such as kidney failure, poisoning, diabetic ketoacidosis (DKA), and shock.
Many of these conditions are life-threatening. If severe, metabolic acidosis may lead to shock or death. In some situations, metabolic acidosis can be a mild, chronic condition.
Causes, incidence, and risk factors Return to top
Many different diseases and medical conditions can lead to metabolic acidosis. For example, diabetes mellitus type 1 (juvenile diabetes), when out of control, leads to diabetic ketoacidosis.
Kidney failure is another important cause of metabolic acidosis. Ingestion of toxic substances, such as antifreeze or excessive amounts of aspirin, can also lead to metabolic acidosis. Shock (extremely low blood pressure) can also cause this condition.
Symptoms Return to top
Most symptoms are caused by the disease or condition that is causing the metabolic acidosis. Metabolic acidosis itself usually causes rapid breathing. Confusion or lethargy may also occur.Signs and tests Return to top
Blood tests to diagnose metabolic acidosis may include:
Treatment Return to top
Treatment is aimed at the underlying condition. In certain circumstances, sodium bicarbonate (baking soda) may be given to improve the acidity of the blood.Expectations (prognosis) Return to top
The prognosis of metabolic acidosis depends on the underlying disease.Complications Return to top
When very severe, metabolic acidosis can lead to shock or death.Calling your health care provider Return to top
Call your health care provider, or go to the nearest emergency room if symptoms of any disease that causes metabolic acidosis appear.Prevention Return to top
Keeping diabetes mellitus type 1 under control may avoid many cases of metabolic acidosis. Avoid ingesting toxic materials.
