Diabetes is one of several diseases that can cause body odor, according to HealthTap. In the case of diabetes mellitus, ingested sugars raise the level of glucose in the blood. Having an elevated blood glucose level is the definition of the disease itself.
Fungal infections can cause body odor that develops in skin folds. Uncontrolled blood glucose levels can initiate infections, says HealthTap. Sugars that aggravate glucose levels can be either simple or from complex carbohydrates.
Symptoms of diabetes include frequent urination, fatigue, excessive hunger and excessive thirst, notes HealthTap. The disease can contribute to many medical issues and events, including heart attack, kidney failure, blindness and limb loss.
