It can do if you don’t control your blood glucose level.
Over time, high blood glucose levels damage your nerves (known as neuropathy) and blood vessels. This can restrict blood flowing to your sexual organs causing erectile dysfunction in men and loss of sensation in women.
Men are more likely to develop erectile dysfunction if they also have other problems such as obesity, high blood pressure or high cholesterol. Psychological problems such as feeling anxious or stressed can also influence your sex drive and ability to get and keep erections.
If you’re having sexual problems, contact your GP for help and advice.
