I don't have fecal BO, but I've suffered from fecal BB for almost 4 years now (I'm 31).
*I've had IBS since I was in high school (16-19).
*I took Antibiotics for Acne for 4.5 years in college (age 19-24).
*My fecal BB varies from fecal to sewage to garbage to even Female BO. And it's strong enough to smell as if it's coming from my body.
*I'm not taking anything now except Betaine HCL and Super Enzymes (from Vitamin Shoppe). When taken 15 minutes before a meal, the fecal BB is greatly reduced but not eliminated.
*I'm never sick (cold, flu, etc). Like, NEVER.
*Everyone smells it, but people with sensitive noses are absolutely tortured by it.
*I used to eat lots of sugars/carbs/fats, but for the last year I haven't eaten bread/pasta/gluten and have drastically cut out sugar, fast food, etc. Doesn't seem to affect the fecal BB at all. And if I don't eat anything, the smell gets 3 times worse!! Strange...
