Sexual Dysfunction
Sexual dysfunction is among the lesser-known signs of undiagnosed diabetes. High blood sugar in men can result in damage to the nerves and small blood vessels responsible for controlling the blood flow to the penis. This can result in erectile dysfunction and is especially common in individuals with type 2 diabetes. For women, diabetes can cause a lower sex drive and vaginal dryness caused by nerve damage, poor blood circulation, and an imbalance of hormones.
