I have a very active 10 y/o daughter. After any meal she eats she goes right to the bathroom within 3 minutes and has diarrhea. She then becomes extremely pale and weak. It does not matter what she eats happens with all kinds of food. She can drop 5 lbs easy in a week. Peds Dr has already done blood work and stool samples nothing shows up. No allergies to foods, no celiac, IBS, crohn s, lactose, gluten, glucose absolutely nothing wrong with her. Does not take any meds and weighs about 64 lbs. Please help!
Hi... Thank you for consulting in Chat Doctor. What your kid is having is not a diarrhea and is only a gastronomic reflux. It is quite common for kids to 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 some kids take food, 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.
