Okay guys I'm gonna start by saying this, I've had a foul smell of fecal Body Odor for the past 4 years to the point where I wanted to give up on life. I got bullied all the time in high school and got told all the time and heard "who farted" "it smells like shit" came across these forums and wanted to tell you all that there is no reason to ever give up on your self. Keep telling your self it will get better.
I found the solution to my problem as well you guys should give it a shot
Take probiotics daily!!
Take laxatives to help your bowel movements. Not too much just enough to get it flowing on a daily basis. If you don't poop it basically sits and rots and comes through your pores or breath. Make sure you go once a day at least! If you can't after laxatives a few times to clear you out than see a doctor.
It worked for me it could work for you! Please give it a shot!!
