Recently, I’ve been experiencing severe kidney pain. After visiting the hospital for evaluation, my doctor diagnosed me with renal tubular acidosis (RTA). Could you please explain what renal tubular acidosis is?

Renal tubular acidosis (RTA) is a syndrome resulting from impaired renal acidification due to various underlying causes. It is classified into several types—including distal RTA, proximal RTA, mixed RTA, and hyperkalemic (type 4) RTA—all of which ultimately manifest as metabolic acidosis. Treatment strategies include alkali supplementation to correct acidosis, potassium supplementation (particularly in hypokalemic forms), or combined approaches; the specific therapeutic plan must be tailored based on the confirmed etiology.
