Veteran actor Dilip Kumar is doing better now. Nephrologist of Lilavati Hospital Dr Jalil Parkar said today that Kumar's kidneys are functioning well and he is not on dialysis. The 94-year-old actor was admitted to Mumbai's Lilavati Hospital on Wednesday morning for treatment of dehydration and a urinary tract infection. Hospital officials had earlier said because of his age, Kumar would be under observation and remain in the ICU for the next two or three days, depending on how his body responds to treatment.
