How young can you be to have IBS?? Or gall baldder issues?

If it's happening with fatty foods (and I'm not an expert, I'm just drawing from personal experience), it could be IBS. I noticed, before I went full on vegan, that when I ate the fast foods, greasy foods, etc. I would have terrible bouts of diarrhea for hours and on occasion (though very rare) days. You should take him in to see a GI doctor. If anything, he can do some tests to rule out some. Also, he can do a test to see if it's the gallbladder by simply pressing on his right lower abdomen. It's basically the same test they do for appendicitis. Keep him hydrated. diarrhea can severely dehydrate people. And since he's ten, it's very dangerous. Also, you might want to try the old fashioned BRAT diet (Bananas, rice, applesauce, and toast). That might ease his pain and help with the diarrhea. But if he's too nauseated to eat, just make sure he's drinking lots of fluids. Pedia-lyte is fantastic for kids who are beginning to get dehydrated. But you can also do sports drinks to replenish his electrolytes. I hope this helps. Keep us posted.

This is interesting as my gastroenterologist states that there is no real condition known as IBS! He said it's a "cop-out" when the doctors are unable to make a diagnosis! I have proven this after being told by about 6 gastroenterologists that I have IBS, which it isn't. Gallbladder/stones usually take years to form, and I have never heard of a child being diagnosed with this.

Do hope your son has seen a doctor by now and that you both have a diagnosis and treatment. Very best of luck and health to him.
