The G6PD enzyme deficiency, common among the Parsis, makes them highly susceptible to certain drugs. The deficiency may cause jaundice in the newborn and severe Homolytic crisis (destruction of red blood cells) in adults. Ask your family doctor to arrange for a blood test to detect whether you have G6PD enzyme deficiency. If you happen to be a G6PD patient, it is essential that you carry your card at all times so that in any emergency you would receive appropriate treatment.
