HEALTH CONDITIONS
Diabetes and ED. Blood sugar shapes your erections.
Men with diabetes are about three times more likely to develop erectile dysfunction, and often 10 to 15 years earlier. More than half of diabetic men experience ED. High blood sugar damages both the small blood vessels and the nerves that control erections. Good glucose control, exercise and weight loss lower the risk, and treatments like PDE5 inhibitors still help most men.
How common it is
Meta-analyses estimate around 50 to 60% of men with diabetes have some degree of ED, compared with far lower rates in men without it.
Why it happens
Chronically high glucose damages the endothelium and the autonomic nerves. Diabetes also often comes with obesity, high blood pressure and low testosterone, which all add risk.
An early clue
ED can appear before diabetes is diagnosed. Unexplained ED is a reason to check blood sugar and HbA1c.
What protects erections
Keeping HbA1c in target, losing weight, regular aerobic exercise, not smoking and controlling blood pressure and cholesterol. These also protect the heart.
Treatment options
PDE5 inhibitors work for most diabetic men, though sometimes at higher doses. If not, options include vacuum devices, injections and penile implants. Testosterone treatment helps when levels are truly low.

QUESTIONS
What people ask before signing up.
Can diabetic ED be reversed?
Sometimes, especially early, with better glucose control, weight loss and exercise.
Does Viagra work for diabetics?
Yes for most men, though success rates are somewhat lower than in men without diabetes.
Does type 2 diabetes cause ED?
Yes. Both type 1 and type 2 raise risk, through blood vessel and nerve damage.
Is ED a sign of diabetes?
It can be. Men with unexplained ED should have their blood sugar checked.
