Hello, my nephew is 6 years old. he eats a lot of different stuff since the morning till about 4 pm, & then at 5 pm he starts vomiting. this has been happening for the last 10 days. we ordered a stool analysis & the only significant resuls were vegetable cells in stool, 1-3 pus cells, & 6-8 pus cells. no ova or parasites or any worms were found. the color is brown, smell offensive & it's semiformed. Could you please suggest the further steps we should take??? Thanks a lot.
