This is Dr. David
you should see a doctor and get some testing.
diabetes can cause you to be in ketoacidosis which can cause odor
stomach infection of H Pylori infection can cause bad odor
bowel infection of small bowel bacterial overgrowth can cause you to have bad odor
if you eat a lot of garlic, this can cause body odor.
you could also have excessive sweat glands in your hands or arm pits which could cause bad odor
surgery or botox injections into excessive sweat glands can help decrease their function and help decrease odor.
you may need antifungal powders or baby powders for your bottom as well to help dry the area and decrease odor and moisture and decrease risks for skin fungal infection.
