12. Fecal Smell on Skin
If you feel like it has been a few days since your last bowel movement, you might have some constipation. Also, a foul smell on your skin that actually smells like feces may indicate you are constipated. Hopefully you figure out that you are constipated before the odor is present, especially if you plan to be in public. Talk with your physician if you are experiencing constipation so that you can receive proper care.
