I've had severe IBS C&D (C-predominant) for 17 yrs. Maintaining a healthy weight has always been a problem. I exercise, meditate and eat a restricted diet. I have a great appetite, the food just won't go through the system fast enough for me to put more in. I eat 4 or 5 small meals a day. Colonoscopy, endoscopy, biopsies etc all clear. I'm not reaching a point where I can't even maintain my low weight and I'm becoming dangerously weak. Any suggestions appreciated.
