Someone told me that IBS tends to go into "remission" and then relapse--that you can seem to be over it, and then it will come back. Is this true? Because I seem to be getting gradually better. I had a bad stomach virus in April of last year, with 2 bad relapses--only to be told that it was IBS, not a virus. Since then, like I said, I have been improving. I only had the really bad diarrhea in April, May, and June--for 2 weeks each time, with nausea so bad I could not eat. I got very weak during each of these attacks. But I thought I was SICK, the kind of SICK that you get over. Are those periods of acute sickness going to come back? I hope not; I really thought I was dying when I was that sick. I can't stand to lose another 20 pounds either--I am only 120, at 5'5". Is it possible those really bad attacks WERE aftereffects of a virus? I didn't think IBS lasted 2 or 3 weeks without relenting; I thought an IBS "attack" only lasted a few hours or so and then went away.
