Renal Tubular Acidosis

Your body’s cells use chemical reactions to carry out tasks such as turning
food into energy and repairing tissue. These chemical reactions generate acids.
But too much acid in the blood—acidosis—can disturb many bodily functions.
Healthy kidneys help maintain acid-base balance by excreting acids into the
urine and returning bicarbonate—an alkaline, or base, substance—to the blood.
This “reclaimed” bicarbonate neutralizes much of the acid that is created when
food is broken down in the body.

Renal tubular acidosis (RTA) is a disease that occurs when the kidneys fail
to excrete acids into the urine, which causes a person’s blood to remain too
acidic. Without proper treatment, chronic acidity of the blood leads to growth
retardation, kidney stones, bone disease, and progressive renal failure.
