I was diagnose with IBS 2 years ago, and I have dairy intolerance.It started after H.pylori infection and dissapear after 2 months. I hade alot of viruses but my stomach was perfectly fine.3 months (almost) ago I got stomach flu, I was having D for 2 weeks. after those 2 weeks I also got upper abdominal pain.it took month and a half for the upper abdominal pain to calm down.now my upper abdominal pain nearly never come, but all this time I ate very little, I had D on & off, and I was in a lot of stress.the last 3 weeks I started eating well and was calm but my stomach just doesn't get it.I have D for every tipe of food she doesn't like (too many).things got better butI still don't digest well.is it normal? really? 3 months???when will it go away?
