Hello, I just wanted to find a solution to an ongoing problem of fecal odor

Gut dysbiosis. It sounds like your gut flora is out of balance and you may have some food intolerances and possibly a yeast overgrowth problem. You can do labs , including stool to check or you could implement a standard protocol and then follow up with your provider. Probiotics , vit d and omega 3 supplementation as well as removing dairy and grains from your diet should be tried for 4 to 6 weeks for benefit.
