Hi-My Dr. suggested I take a Lactose intolerance test and was tested positive. after taking dairy enzymes for 2wks I was completely odor free. Because I could not digest dairy foods I developed SIBO Small intestine bacterial overgrowth in my gut which after years cause my odor. From feces smells to garbage, rotten eggs but mostly sour milk. I went thru this for twenty years and now I am completely odor free. Please get tested for Lactose. Good luck and please let me know if you have any questions.
