My sister started having intestinal problems a couple of years ago. She would go from being constipated to having diarrhea. Her doctor told her that she had IBS and started her on some medication. It was hard for her to work sometimes because if she ate lunch, it could be a disaster. She would often have horrible stomach cramps.
A few months ago, she started having more trouble. She was having very bad stomach cramps and was extremely constipated. She was admitted to the hospital and they started running tests. They told her that she had a swollen colon and was very impacted. She had to have a small surgical procedure done to remove the impaction.
She is doing much better now and can finally eat and not worry about the consequences.
