Difficile or other pathogen, lactose intolerance, gallstones, ovarian cancer, pancreatic problems, an obstructive problem w/ the colon, inflammation anywhere in the abdomen or urinary tract leading to an ileus(slow down in the contractility of the colon), etc..Go back to ur doc for a more thorough evaluation. ...Read more

I was recently sick with stomach flu and I ate pizza today and now I'm passing gas every minute. Is it just from pizza or because I was sick?

I was recently sick with stomach flu and I ate pizza today and now I'm passing gas every minute. Is it just from pizza or because I was sick?

Probably both: It's common for people who normally tolerate milk to have gas, cramps, loose stools, etc with milk, cheese, etc after viral gastroenteritis ("stomach flu"). The infection reduces the intestinal enzyme lactase, which digests milk sugar. Poorly digested milk gives intestinal bacteria a feast -- and whey THEY digest it, acid and gas are produced, with symptoms like yours. It should improve soon. ...Read more

I have horrible smelling bowel movements and gas after gastroenteritis. Stool looks a little loose. It has been about 8 days. Muscle weakness too. ??


I have horrible smelling bowel movements and gas after gastroenteritis. Stool looks a little loose. It has been about 8 days. Muscle weakness too. ??

Gastroenteritis: I don't think that the horribly smelling stool is of concern but the loose stools of viral gastroenteritis usually resolve after a week although it can be followed by an irritable bowel syndrome. If significant diarrhea is prolonged the stool should be cultured to check for pathogens that need treatment. In the meantime avoid harsh roughage,take kaopectate (kaolin and pectin) as needed. ...Read more

Gut bacteria: Digestion problems after a recent illness may be due to alterations of the natural bacteria in the gut. This can occur due to antibiotics taken for an infection or the infection itself. Typically the natural bacteria will repopulate over time however taking a good quality probiotic supplement may help. ...Read more

Recovering from stomach flu, still have gas and diarrhea. Will pepto bismol (bismuth subsalicylate) help or make things worse?

I had stomach flu 5 days ago. The vomiting/diarrhea stopped, but now I eat anything and get massive gas and have yellow stool, or diarrhea again. ?

I had stomach flu 5 days ago. The vomiting/diarrhea stopped, but now I eat anything and get massive gas and have yellow stool, or diarrhea again. ?

Still healing: Even though you've recovered from your gastrointestinal infection, some effects still remain. It may take a while for the inner lining of the intestines to heal and for normal digestion to return. During this time, you should increase fluid intake, eat bland foods and avoid alcohol, beans, fatty foods & raw veggies. Limit dairy products to yogurt, lactaid & a bit of cheese. You'll be fine soon. ...Read more
