Hi Doc, My 4 and a half month old baby boy is suffering from loose motios from last 3 days. There is mucus in his stool as well. The motion is very thin and watery as well. He is doing motion as early as he is taking mother feed or anything else. We tested his stool and the report is that he has redusing substance positive. could you please explain what excatly is that. Also the doctos to which we have consulted suggested not to give him milk for another 2-3 days not even mother feed. he said he has diarreaha due to lactose intolrence

### output:

Hi... Thank you for consulting in Chat Doctor .1. This is not infective diarrhea.2. This is not lactose intolerance either.3. In any exclusively breastfed baby, presence of reducing substances in the stool sample is normal. One cannot diagnose lactose intolerance based on this. What your kid is having is not a diarrhea and is only a gastronomic reflux. It is quite common for babies of this age group t pass small amount of diarrhea or loose stools soon after feeds. This need not be treated as diarrhea and especially antibiotics are not indicated. When the baby takes milk, the stomach expands - then when it is contracting it sets off a wave form which moves down the intestines and when that wave reaches the lower down rectum, a small quantity of the stool is evacuated out. This is the basis for gastronomic reflex. Do not worry. Unless the kids having low urine output or very dull or excessively sleepy or blood in motion or green bilious vomiting...you need not worry. Hope my answer was helpful for you. I am happy to help any time. Further clarifications and consultations on Chat Doctor are welcome. If you do not have any clarifications, you can close the discussion and rate the answer. Wish your kid good health.
