Hello doctor, my son is 1 year and 10 mths old. He has severe diarrhea which is watery, brown and foul smelling for about 3 weeks about 3 to 4 times a day. Last night his stool was green with a pudding like consistency. He also vomits every day 2.5 weeks and has loss of appetite 3.5 weeks. He also has abdominal painI ve been giving him only gatorade and pedialyte to drink. He eats very bland foods and no sugary, acidic or dairy foods for about a week and a half. His attitude has also changed, he s cranky, sometimes doesn t want to be touched and he sleeps all the time. He s had an x-ray , abdominal ultrasound, and stools tested for rotavirus , o/p, bacteria and c- deficil, everything came back negative and clear. He was on zofran for a week. Please help.
