Five weeks ago, I came down with what I think is a stomach virus (stoll samples all came back negative for parasites and bacteria). I am 6 months pregnant, and had no trouble eating almost anything before this sudden disease occured, although I have had intermitant periods of diarrhea in the last year. My symptoms this time were only diarrhea, and almost always at night. No fever above 99. The diarrhea itself was yellow, flaky, and full of mucus and undigested food for two weeks (no blood at all). I did become dehydrated, and was given an IV at my doctors office. After that, I felt somewhat better. I then went into a pattern of two days of constipation and then a very painful, sometimes normal, sometimes diarrhea at night again for one night. It is no longer yellow (brown now), however, it it sometimes flaky after starting out normal and has some trace of mucus. I have been on the BRAT diet for this entire month, consume only water or electrolyte solution for drinks, and any introduction of a few bites of pureed vegetables or plain cooked chicken have given me severe gas pains and the painful movements.
My nurse beleives that my intestinal villi have been damaged by a virus or that I have colitis or other IBS and that is why any foods other than very mild ones cause the trouble. My question is, Once the intestinal villi are damaged, how long does it normally take for them to heal? Does it appear that I did indeed have a virus that caused all this? Because I am pregnant, I cannot have a colonoscopy to diagnose IBS or another disorder, although I plan on it once the baby is born. In the mean time, I need to know what to do to get adequate nutrition and would feel better mentally if I had a timeline for healing.
