What is the link between blood pressure, blood sugar and eye health?

Having problems with your eye health can be related to having high blood pressure and high blood sugar.

It’s important to keep your blood sugar levels under control. People who do not control their blood sugar levels are four times more likely than people with close to normal levels to develop eye health problems, according to the American Diabetes AssociationOff Site Icon (ADA).

Your vision can also become temporarily blurry if you have high blood sugar levels, according to the ADA.

High blood pressure can cause damage to the blood vessels in the retina, according to the National Institutes of HealthOff Site Icon (NIH). The higher your blood pressure is and the longer it has been high, the worse the damage to your eyes can be.

The other issues high blood pressure can cause to your eyes, according to the NIH, include:

  • Blocking the blood supply in the arteries that go to the retina
  • Blocking the veins that carry blood from the retina
  • Damaging eye nerves because of poor blood flow

Smoking adds another risk to damaging your eye health, so if you have diabetes and smoke, choosing to quit smoking would be the best option, according to the ADA.

For more information about how eye health is affected by blood pressure and blood sugar, talk with your doctor.
