Hi. Yes, erectile dysfunction is quite common with diabetics. Ask your doc for advice and Viagra/Cialis on prescription if needed. The important thing for blood sugar and ED is to reduce your carbs and portion sizes to a level that keeps the blood sugar within the good, NICE, range. Many of us will go for maximum total daily carb intake of, say, 150gm/day or even less. See what level works for you keeping blood sugar and weight down. This in turn avoids blood vessels getting blocked long-term increasing ED and the loss of feeling in limbs etc.
