Modified Atkins diet for drug-resistant epilepsy and the risk of urolithiasis.

KD has been increasingly used in epilepsy management and beyond. The potential side effects of such diet should be highlighted while valuing the merits. KD increases the risk of renal stones because of hypercalciuria among other causes. We recommend initiation of prophylactic measures once KD is commenced by maximizing fluid intake and urine alkalinization with estimation of urinary calcium/creatinine ratio and renal ultrasound in patients with relevant symptoms.
