...I feel for you and hope you get the tests/results/help soon. I have had "ibs-D" for many years since radiation treatment to pelvic area , as has husband, and we both have bowel issues .. I also had c.diff few years ago and now fecal incontinence... we are both Seniors: is your medical problem mostly stomach or bowel? Our diets are very limited, eg no fresh veggies or fruit except bananas and him apples; mostly potatoes, carrots etc. its horrible as I used to love cooking and both of us enjoyed eating , and miss salads and fruits and many other things, but when we do eat something not on our lists we pay for it with cramps, diarrhea etc. Even eating plainly still have issues but only take Imodium. Wishing you the best....J. p.s. Can you tolerate those nutritional drinks like Ensure etc. Hope you get some helpful answers here...... take care.
