Unique, where on your body do you feel that your smell is worse? Can you identify areas that seem worse. If so I would start looking at these areas first. It’s easier for a medical professional to focus there and begin some research in that area. Do other people tell you what the bad odour smells like? This could be an objective clue. Ask people what your smell is like. Let them know that you welcome their comments. Let a good friend smell you from head to foot and tell you where the smell is worse. One suggestion, check and make sure you have not left a tampon inside you by accident as this can apparently create a bad smell that would get worse as time moves on. Keep looking for the cause, don’t give up. The answer is out there.

Unique I am sorry that it has been so difficult for you to identify the problem. It’s too bad that there isn’t a scent meter that could analyse the scent and give answers with respect to where the scent comes from. Maybe there such a test I don’t know. Try enquiring at university medical centres. The other thought that I had is also far fetched but you talk about a fecal odour and it made me think about a friend who had intestinal surgery. He had to wear a bag and change it when it was full and I asked him about whether the fact that fecal matter was outside the body would him to have a odour that other people might be able to smell. He said that he took pills that prevented any odour. Just as a thought, maybe if you could try these type of pills whether it might have an effect on reducing odour unknown odour. A shot in the dark maybe. The other question is whether your hormones are out of whack. That might have an impact on you. Also, do you have any skin problems or scalp problems? Would you consider eliminating personal care products or changing brands to see whether you are allergic which might set up a secondary effect on your body resulting in a noxious odour. I think you should be in the care of a specialist, perhaps starting with a dermatologist. Not sure whether you mentioned seeing an ear, nose and throat specialist, and an endocrinologist might be helpful. I am not a medical professional, just throwing out suggestions that might be helpful.

Maybe what you are actually smelling is the inside of your own nasal cavity.

I'm sorry for what you're going through. Could it be an abnormal strain of bacteria growing in your stomach or airways? I don't know how to even check for that.

This post is quite old but I am experiencing the same problem for about 2 years. I’ve given up on doctors and I’ve been prescribed 17 different medications for the pain in my stomach and antibiotics for something I’ve never been diagnosed with. 2 colonoscopy’s and 2 endoscopy’s, countless other tests being done, doctors can’t/don’t care to help me with my problem. I’ve been suicidal several times in the past 2 years. I am severely depressed and insecure and my marriage is falling apart. I don’t know what to do anymore. I’ve spent hundreds of dollars trying supplements and supposed cures online. I have gone through 3 doctors and 4 separate specialists and therapy doesn’t help any

I think the issue is functional , i mean something wrong with your pelvic muscles or nerves , try strenght your abs core pelvic muscles by kegel or other methods.

Also meanwhile try Devrom tablets till your get your pelvic floor strong.

Have you had your liver checked? I heard about a young man in the U.K. who had a body odor problem caused by problems with his liver. (His odor was that of fresh, hot urine but maybe they're related to yours?) Anyway good luck; hope for the best for you.

He/She mentions that the smell is like shit, not urine smell, and if he/she has done all the tests and they are negative, it means that the problem is functional, do an electromyography of the pelvic floor, your muscles are failing.

I know this is an old post and hopefully you’ve found some help, but in case you’re still looking for answers, I noticed you mentioned SIBO but didn’t mention any follow-up for it. I don’t know if SIBO can cause odors to exude other than as flatulence, but do you know what bugs you have proliferating in your small intestines that led to the diagnosis? I have SIBO, I don’t have the odor problem you have, but I have found the most help from a registered dietitian/nutritionist I’ve been working with. The traditional, allopathic medicine practiced by most MDs around where I live has not been helpful. They perform procedures and run tests, but the help I get managing the results comes from my nutritionist. It’s another avenue for you to consider if you’re still looking for help and haven’t already consulted one. I’d say find one that is a GI or SIBO specialist, that will give you the most targeted help. Best wishes.
