I've never posted here before but have a read a lot of helpful posts over the past 15 months and want to return the favor now that I believe I have some answers, and certainly hope that I can help someone else. I've been dealing with recurrent SIBO (alternating constipation and diarrhea, constant nausea, extreme bloating, gas, belching, weight loss of 14% of my body weight, insomnia, debilitating lower back pain, etc.) I saw my 7th doctor this week and she feels very confident that my recurrent SIBO is caused by Exocrine Pancreatic Insufficiency (EPI), which is a lack of pancreatic enzymes. Her theory is that the lack of ezymes caused me to be unable to digest any food, and that the undigested food traveling through my GI track provided an abundance of nutrients for my gut bacteria, causing them to overgrow. Apparently the condition is very common in dogs, but I haven't been able to find much about it in humans. I've now started treating with prescription pancreatic enyzme supplements with all meals and snacks, and will report back in a few weeks. My other doctors all seem to agree with this new diagnosis from the new doctor and all seem to think I'm on the right track. I sure hope so.
I did have a pancreatic enzyme stool test done almost six months ago and the levels came back within the normal range, but on the low side of normal. My new doctor believes that the "normal" range is very broad, and that a result on the low side of normal should warant further exploration, and that in my case given the recurrent SIBO, she feels the enzyme supplement is the key to knocking out the SIBO. This new doctor (who is a former professor at a top medical school and now travels around the country lecturing) said that most dotors associate EPI with chronic alcoholism and tend to only think about it with patients who are "middle-aged men with beer guts." I'm a female with a 15+-year history as an extreme underance athlete and very healthy diet, so she said most doctors just didn't put in my that "box" of patients for whom they suspect pancreatic problems, so never connected the dots. In my case she thinks the EPI was the result of a genetic predisposition that was tiggered by a severe, acute GI infection I developed while in Africa shortly before my symptoms began. I sure hope she's right, and that this information can help someone else!
