ED and diabetes

Why diabetes and ED are linked

Erectile dysfunction is common in men with diabetes. Over time, diabetes can damage the small blood vessels and the nerves that are needed for an erection. Other things that often go with diabetes - high blood pressure, high cholesterol, weight gain, lower testosterone - can add to the problem.

Because of this, ED in a man with diabetes is usually caused by several factors at once. Good care looks at all of them together.

ED can be an early warning

In men with diabetes, erectile dysfunction can be an early sign of wider blood vessel problems, including those affecting the heart. For this reason, the assessment usually includes a general health review as well, so any other risk factors can be picked up and managed.

How it is assessed

Assessment usually includes:

• A detailed history, including how well the diabetes is controlled, current medications, and the pattern of erectile difficulty.
• A physical examination.
• Blood tests, including a HbA1c (long-term sugar control), cholesterol, and a hormone profile (such as testosterone).
• A review of all current medications, since some can contribute to ED.
• A discussion about psychological and relationship factors.

The main treatment options

There is no one-size-fits-all answer. The plan is built around the person, their other conditions, and their preferences. It usually combines general health work with specific ED treatment.

Foundations

• Better blood sugar control, working with the GP or endocrinologist.
• Managing the heart risk factors: blood pressure, cholesterol, smoking, and weight.
• Lifestyle: regular physical activity and weight reduction where relevant.
• Reviewing medications that may be contributing.

Specific ED treatments

• Tablets (PDE5 inhibitors) are usually the first medical treatment. They can work well in men with diabetes, although the response rate is generally a bit lower than in men without diabetes.
• Vacuum pump devices - non-medication option, used alone or with other treatments.
• Penile injections - often effective when tablets are not enough. Training and support is provided by the men's health pharmacist. See the short version: penile injection therapy.
• Testosterone replacement - only if testosterone is clearly low on repeat tests, with appropriate monitoring.
• Penile prosthesis surgery - a surgical option when other treatments have not given a satisfactory result.

Working with your other doctors

Diabetic ED sits at the meeting point of urology, diabetes care, and heart care. The clinic coordinates with the GP and the diabetes team so that the plan is joined up rather than scattered.
