[|Human|] Hello my 2 1/2 year old often has diarrhea. His poos go from dark and sticky to sand and grainy to watery with undigested food. Its not uncommun for him to go 10 to 12 times during the week-end. We had him tested for celiac disease and his results came back negatif. We also tried to cut all milk products thinking that maybe he was lactose intolerant and then again the mustard smelling loose stool keeps on coming back. He recently had a grow spurr and is now back in the 50 th percentile and he is struggling to stay in the 10th percentile for weight. he currently weighs 26 pounds. Could you please help us figure out what might be wrong with our son. Thank you kindly
