Acidosis
Definition
Acidosis is excessive acid in the body fluids.
Causes
The kidneys and lungs maintain the body's acid/base (pH) balance. Acidosis occurs when acid builds up or bicarbonate (a base) is lost. The major categories of acidosis are respiratory acidosis and metabolic acidosis.
Respiratory acidosis develops when there is too much carbon dioxide (an acid) in the body, primarily caused by decreased breathing. Other names for this include hypercapnic acidosis and carbon dioxide acidosis.
There are several types of metabolic acidosis:
- Diabetic acidosis (also called diabetic ketoacidosis and DKA) develops when ketone bodies build up during uncontrolled diabetes.
- Hyperchloremic acidosis results from excessive loss of sodium bicarbonate from the body, as in severe diarrhea.
- Lactic acidosis is a buildup of lactic acid. This can be caused by:
- Alcohol
- Cancer
- Liver failure
- Low blood sugar (hypoglycemia)
- Medications such as salicylates
- Prolonged exercise
- Prolonged lack of oxygen from shock, heart failure, or severe anemia
- Seizures
Other causes of metabolic acidosis include:
