Acidosis - Definition

Ask a question


Acidosis is the excessive acidity of the blood when the pH becomes inferior to its normal level (between 7.38 and 7.42). Acidosis appears in people whose bodies have difficulties efficiently eliminating the acid by-products produced by the body or who have a high accumulation of these acids. Different types of acidosis can be distinguished: the most frequent are metabolic acidosis most often in the case of diabetes, but also in severe cases of diarrhea or fasting; respiratory acidosis is due to poor elimination of respiratory by-products (carbon dioxide or CO2) by a decrease in pulmonary activity; renal acidosis is due to poor elimination of acid by-products by the kidneys.
