I am totally frustrated as I am unable to maintain a healthy weight. I am five feet, six and a half inches and I weigh only 118 pounds. I maintained a weight of approx 127 to 130 lbs for many years but when I developed IBS about 10 years ago I lost almost 10 lbs the first year. However my weight remained steady at around 120 lbs until these past few months. I can weigh as little as 116 pounds in the morning. I was under the belief that with IBS there is no weight loss as most nutrient absorption occurs in the small intestine and not the large intestine which is where most of the problems occur with IBS (ie the colon). In any case, am very wary of using imodium - will relent and take perhaps one half to one per week. It works for several days - constipation, and then I revert to the diaharrea again - often worse. We go out a great deal and travel a lot so it becomes a real obstacle trying to cope with this condition. I am getting quite worried about this weight loss and my current situation of watery D. It used to go away after a couple of days, but this time I cant seem to break the cycle. Is my IBS getting worse, and will this weight issue continue? I will be seeing my GI specialist in about a month. Had my last colonoscopy about 4 years ago, so not sure what he will do now. Any suggestions or information would be appreciated.
