Diabetes and Fungal Infections
The culprit in fungal infections for people with diabetes is often Candida albicans. This yeast-like fungus can create itches rashes of moist, red areas surrounded by tiny blisters and scales. Problem areas include moist folds of the skin, such as under the breasts, around the nails, between fingers, and toes, in the corners of the mouth, under the foreskin (in uncircumcised men), and in the armpits and groin. Common fungal infections include jock itch, athlete’s foot, ringworm (a ring-shaped itchy patch) and vaginal infection that causes itching. If you think you have a yeast or fungal infection, call your doctor. These infections are treatable with medication.
