How is a belly button yeast infection diagnosed?

Your healthcare provider may perform a physical examination. They may be able to tell you have a yeast infection by looking at the skin of your navel area. A bright red rash is a common sign of a belly button yeast infection.

Your healthcare provider may want to test a sample of the infected area. They’ll use a tongue depressor or scalpel to lightly scrape some of the skin from your navel area. A lab technician will examine the sample under a microscope. Or they may place the sample in a culture. A culture is a substance that allows the sample to grow so the fungus can be identified.

If you do have a yeast infection, your healthcare provider may recommend testing for diabetes. High blood sugar levels in people with diabetes are used as food for yeast and help it grow.
