I ve had digestive issues for several years. I was diagnosed with IBS and have had a colonoscopy and endoscopy that showed a small diverticuli. Lately (month or more) I may not have a bowel movement for 2 weeks. I cannot eat or drink very much and tend to only be able to take in at most 900 calories a day. My stomach is distended also. I take daily fiber, a womens multi-vitamin, B-12, Digestive Advantage, eat mostly raw vegetables and fruits, drink 96oz. of water on average everyday. If I try a laxative, even prescribed, it causes me to vomit violently and will cause days of diarrhea. Then it starts all over again with the constipation. There must be something more to this than simple diverticuli? Or IBS. My family has a history of autoimmune issues, but my doctor can find nothing wrong after blood work, ultrasounds and CT scans showed nothing. I have lost nearly 80 lbs in the past year also. My sister and neice have a condition called gastroparesis, but I can t afford the testing.
