If you are obese, you have an increased risk of erectile dysfunction (ED). Obesity causes insulin insensitivity in the body which leads to high blood glucose levels. Over a period of time high glucose levels cause damage to blood vessels that carry blood to the penis. It can also cause damage to the nerves that innervate the penis.
Also, weight gain can be a result of increased blood cholesterol. Increased levels of cholesterol is responsible for the deposition of lipids in the walls of vessels. This in turn reduces the supply of blood to vital organs. The flow of blood is important for erections to occur. When a person has the problem of erectile dysfunction, the penile artery gets affected.
Obesity can also lead to abnormal testosterone level which can also cause erectile dysfunction.
