Lactic acidosis is when lactic acid builds ups in the blood stream faster than it can be removed. Lactic acid is produced when oxygen levels in the body drop.
The most common cause is intense exercise. However, it can also be caused by certain diseases, such as sepsis, respiratory failure, AIDS, cancer, and kidney failure.
Metformin, a common medicine used to treat diabetes, can also cause lactic acidosis. People taking this medicine should have their electrolyte levels checked 1 - 2 weeks after starting it.
The primary treatment for lactic acidosis is correcting the underlying medical problem that causes the condition.
