What is the term for excessive acidity of body fluids?

The term for excessive acidity of body fluids is acidosis. This condition occurs when the pH level of the blood and other fluids in the body falls below the normal range, indicating an excess of hydrogen ions or a deficiency of bicarbonate. Acidosis can result from various factors, including respiratory issues or metabolic disturbances, and can lead to significant health problems if not addressed.

Alkalosis, in contrast, refers to a condition where there is an excess of base (alkali) in the body fluids, resulting in a higher pH. Hemorrhoid is unrelated, as it pertains to swollen veins in the lower rectum or anus. Adenoma refers to a type of benign tumor that originates in glandular tissue, which is also not connected to the acidity levels in body fluids. Understanding these distinctions helps clarify why acidosis specifically denotes an increase in acidity, making it the correct choice for this question.
