2. An abnormal increase in the acidity of bodily fluids due to either acid accumulation or bicarbonate depletion.
Strictly speaking, the term acidemia would be more appropriate to describe the state of low blood pH, reserving acidosis to describe the processes leading to these states; however, most physicians use the terms interchangeably.
Too much acid in the body is a distinctly abnormal condition resulting from the accumulation of acid or from the depletion of alkaline reserves.
In acidosis, the pH of the blood is abnormally low and is associated with diabetic ketoacidosis, lung disease, and severe kidney disease.
The opposite of acidosis is alkalosis in which there is too high a pH factor due to an excess base or insufficient acid in the body.
