Renal tubular acidosis is usually associated with chronic renal conditions and is rarely encountered in pregnancy. It may be inherited causing osteomalacia and rickets in children or acquired following autoimmune diseases or following exposure to nephrotoxic agents. It is known to worsen during pregnancy and if left untreated may cause maternal and foetal morbidity or death. We report a 28-year-old woman, gravida 3 para 2, who presented at 30 weeks gestation with lethargy, weakness and generalized myalgia. Investigation revealed severe hypokalaemia and a systemic metabolic acidosis due to proximal renal tubular acidosis. Her previous pregnancies were both complicated by foetal losses at term. Following prompt correction of her electrolyte disturbance and metabolic acidosis, she went on to deliver a healthy female infant at term. Regular evaluation up to 1 year post-partum revealed mild persistence of her hypokalaemia. At 1 year, the infant showed no signs of the disorder and is growing normally.
