Renal Tubular Acidosis Type II

Type II renal tubular acidosis, also called proximal, is a disorder in which the initial portion of the renal tubules does not adequately reabsorb bicarbonate, a substance that helps maintain the body's acid balance. It is part of the disorders of the kidney's tubular function.

Common symptoms: muscle weakness, fatigue, and, in childhood, difficulties growing as expected.

Common causes: it can be inherited or appear linked to other conditions that affect kidney function and, at times, along with other losses of substances through the urine.

Which specialist treats it? The pediatric nephrologist studies how the kidneys work and the chemical balance of the blood in children. If these abnormalities appear in routine tests or the child has weakness and poor growth, it is advisable to seek a specialized evaluation.
