Thank you. My 20 y.o. Nephew felt congested and fatigued all day. No hx. Of any medical conditions. He is not prescribed any message/TX. He ate a large bowl of pasta/ziti, clamp chowder, two glasses of iced Tea and a few entree pieces. Then stood up and lost consciousness. Ems came, sugar level, blood pressure and his awareness/responses were normal. Could his blackout be from a carbohydrate overload?
