Sexual problems

High blood glucose levels over a long period of time can cause damage to the blood vessels and nerves that supply blood to your sexual organs. This can lead to a loss of sensation which means that you may find it difficult to get aroused.

High blood glucose levels also make both male and females more susceptible to developing infections such as thrush or urinary tract infections (UTIs). This happens because there is a lot of sugar in the urine, which is a perfect breeding ground for bacteria and fungus to multiply.

You can reduce your risk of getting thrush by keeping your blood glucose levels under control, avoiding perfumed shower gels or wipes, wearing cotton underwear, using condoms to stop it spreading and taking showers instead of baths.

Issues that can affect men

For men, the most common occurrence is erectile dysfunction, which is sometimes known as impotence. This is when you are unable to get or maintain an erection and there are several reasons why this may happen.

It could be down to limited blood flow, nerve damage, damaged blood vessels, certain medications or because of emotional or psychological problems. Having diabetes for a long time can increase the risk and 50% of men with diabetes over 50 years old report problems with erections.

In the film below, Colin talks about his experiences with erectile dysfunction and Dr Debbie Wake discusses potential treatment options.

Issues that can affect women

For women, the damage to blood vessels and nerves caused by high blood glucose levels can affect the vagina and the vulva. These changes can lead to a loss of sensation in this area which means that you may find it more difficult to produce lubrication needed to help with sex.

This lack of lubrication can cause vaginal dryness which can make sex uncomfortable. Vaginal dryness can often be improved by using a sexual lubricant or vaginal moisturizer, but if it is causing you problems, speak to your GP or diabetes care team for further advice.
