Unmasking Distal Renal Tubular Acidosis in a Young Female: A Case of Metabolic Acidosis With Hypokalemic Paraparesis.

This case report aims to highlight the diagnostic challenge and clinical significance of type 1 distal renal tubular acidosis (dRTA) in young patients presenting with hypokalemic paralysis. A 19-year-old female presented with vomiting, progressive lower limb weakness, and severe hypokalemia. Investigations revealed normal anion gap metabolic acidosis, elevated urinary pH, and renal potassium loss. After ruling out other causes, a diagnosis of dRTA was made. She responded well to potassium and bicarbonate therapy. Early recognition and treatment are essential to prevent complications and ensure full recovery.
