I am a 23 yr old female. 5'4 and 135lbs. I have been experiencing stomach aches and bloating now for 4 weeks. After I eat my stomach feels really bloated and sticks out so I look pregnant. Also, my bowels have been irregular also for the past weeks. At first I couldn't go for a few days, then would have diarrhea for couple days. Now, I go a few times a day but only a very little amount of soft stool. I have also felt a little nautious and tire in the evening, but it may be due to stressing out of it. I did have an ulcer when I was 12 and they said it was due to an hpylori bacteria? Not sure if this could be related... Do you have any answers?
