I'm new to the BB, though not to IBS. Here's my question. When I read about the symptoms of IBS versus other diagnoses, it always says IBS is not associated with weight loss. I've had IBS for about 10 years, and I can tell you, during my episodes, which may last a few months, I lose major weight (at least 8-10 pounds). Does this happen for other people? I do cut way back on what I eat, to avoid the "D". Should I just go ahead and eat more, and just use more Imodium, or do other people find they lose weight, too? I really need two sets of sizes of clothes.

Don't panic!! My first major episode of IBS I lost 40lbs in 5 weeks, they put me in the hospital, ran every test even to ct-scan, and found nothing but NERVES and IBS!!!! I loose weight when I'm having episodes all the time....

Same thing with me---lost 20lbs. in 4 days, another 20 lbs. the next month. Did all the tests, came back with IBS--my family thought I had cancer or something. My doc said it wasn't the IBS, it was that I refused to eat since everytime I did I had a D attack. I finally got back on an even keel and my weight has been pretty steady for the last year or two.

Yes, I lost weight too. I guess about 25 pounds in 3 months. The weight is not due to IBS but the anxiety, nerves, and drastic diet change that comes along with having IBS. I had blood tests, GI work, and nothing found. My weight has now been stable for the past 4 months. Wish I could soem back though.

This isinteresting.... I have the opposite problem. I think it has to do with individual metabolism.When I have a prolonged period of D, I actually gain weight. I think my body says "Hey, were losing a bunch of fluid here!" and retains water. Then, when my D clears up, I lose the water weight gain. I can go up and down 4 to 5 pounds within 24 hours.There is so much individual variation with this disease, and so many feedback mechanisms within our bodies that we don't know about.Keeps life intersting!

What made me go for the colonoscopy and "official diagnosis" was weight loss. I lost between 20-30lbs and was sure I had cancer. I had IBS long before that but it seemed to peak when my son was about 3. I had trouble gaining weight when I was pregnant, only could manage 17 lbs, Peter was 3 weeks early and 5lbs3oz. Whatever I ate came back almost immediately to the point where I didnt want to eat anything. I gained back that weight ( a long, slow process) but during a real bad flareup of D, I can loose weight again. I feel like my bowel is sometimes just packed with you know what, somedays I go and go so much(not D-hoselike huge stools) that I feel that I must have dropped 10 lbs! but definately a dress size. After a bad bout of D or even just before it I notice that I am sort of puffy feeling, my wedding ring gets tight and my ankles feel alittle swollen. I guess I just noticed it in the last year or so, I am getting older and am perimenopasual(isn't life grand? LOL)so I always thought it was that. My gyn told me a month ago that all my wonderful PMS symptoms (which IBS is one of)will probably get even more intense as I approach menopause. What a life.------------------Nancy
