Yeast and other fungi use glucose for energy and thrive in an environment that is high in sugar. Yeast infections can occur in both men and women. Infections can grow in any place on the body that is a warm, moist fold of the skin, including:
Between fingers and toes
Under breasts
In or around sex organs
People with high blood sugars also have a high risk of developing bacterial infections like urinary infections, chest infections, and skin infections and boils. The cells that fight infections are called neutrophils and their function is impaired if the glucose level is above 11mmol/l (or 200mg/dl).
