Doctor, Subject: Grandson has ongoing bouts of constipation since 8 mo old. He is now 3 years-10 months and still is being treated by taking a prescribed laxative and a special diet. He is still battling the issue though. Either severe bouts of diarrhea or constipation. He is all of 28 lbs and catches any visus or illness daycare dishes out. My Question is: Why won t his Physician test him and see what the real problem is instead of just treating the symptoms for so long. The child is under-weight, under-height and it s plain to see his body don t seem to be getting the nutrients it needs from what he does eat. He is ahead as for comprehension and skills for his age though.
