Sexual dysfunction is any problem that regularly interferes with an individual’s ability to perform sexual intercourse. Changes in sexual functioning are common as people age. Having diabetes, however, can result in earlier onset and increased severity of sexual problems. 

Diabetic men and women are more likely than nondiabetics to experience sexual dysfunction. Depending on the cause of sexual dysfunction, its onset may be sudden and (usually) temporary, or gradual and permanent. Many diabetic patients experience a slow and steady decline in sexual functioning.

Sexual dysfunction in individuals with diabetes typically results from damage to the blood vessels (diabetic angiopathy) or nerves (diabetic neuropathy), and poor control of glucose (blood sugar). Many people with diabetes also suffer from high blood pressure, obesity, unhealthy cholesterol levels, fatigue, infections, hormonal conditions, bladder problems or depression, all of which can also contribute to sexual problems.

Because of differences in anatomy, men and women experience different types of sexual dysfunction. Patients experiencing sexual difficulties are encouraged to discuss issues openly with their partner and seek appropriate treatment.
