How Diabetes Can Affect Erectile Function in Men
Diabetes can affect how a man’s body works in several ways.
When blood sugar stays high for a long time, it can harm blood vessels and nerves.
Erections need good blood flow and clear nerve signals, so these changes may make erections harder to achieve or maintain.
Some men may also have lower testosterone.
But diabetes is not the only possible cause: stress, smoking, alcohol, medicines, and other health problems can contribute too.
A doctor can help look for the causes.
Keeping blood sugar, blood pressure, and cholesterol under control, staying active, and eating a balanced diet can support overall health.
The article says men with ongoing erectile difficulties should talk with a healthcare professional.
Prolonged high blood sugar can harm blood vessels and nerves involved in erectile function.
Reduced blood flow to the penis and disrupted nerve signals may affect erections and arousal.
Some men with diabetes and related metabolic concerns may have lower testosterone.
Erectile difficulties can have other causes, including stress, smoking, alcohol, medications, and other health conditions.
The doctor recommends discussing persistent difficulties with a healthcare professional and managing blood sugar and other health factors.
