Eye Problems That May Indicate You Have Type 2 Diabetes

One of the type 2 diabetes symptoms is blurred vision. If you have this condition, you might lose sharpness in your eyesight and may not be able to see the fine details of an object. According to Diabetes UK, around one in three people predisposed to the condition will suffer complications with their eyesight by the time doctors diagnose them with type 2 diabetes.

In the case of blurred vision, it can happen unilaterally (one eye) or bilaterally (both eyes). Doctors point to high blood sugar levels as the culprit of this condition. The high levels of sugar cause the lens inside the eyes to become inflamed or swell.

A Permanent and Serious Damage

If you are experiencing blurred vision, it might indicate you already have this chronic ailment and that it is not being properly managed. Consistent high levels of blood sugar can cause damage to the back of your eye or retina. This is known in medical circles as diabetic retinopathy.

The retina requires a steady supply of blood to function properly. This blood supply is delivered to it using a network of miniature blood vessels. With time, uncontrolled type 2 diabetes, characterized by consistently high levels of blood sugar, can cause damage to the blood vessels delivering blood to the retina. This occurs in three major stages, namely, background retinopathy, pre-proliferative retinopathy, and proliferative retinopathy.

Background Retinopathy

This happens when small bulges develop in the tiny blood vessels, causing them to bleed slightly. This does not oftentimes affect your vision.

Pre-Proliferative Retinopathy

In this situation, the blood vessels sustain widespread and more severe changes. This includes the occurrence of considerable bleeding into the eye.

Proliferative Retinopathy

This condition is marked by the scarring of tissue and the development of new blood vessels on the retina. These new blood vessels, however, are weak and can easily bleed, causing more damage and loss of some vision.

The National Health Service, in an advisory, said it often takes many years for diabetic retinopathy to reach that point where your sight is already threatened. If left unchecked and untreated, it can lead to partial or total blindness.

Common Symptoms of Diabetes

Other symptoms of diabetes that people need to be aware of are feeling more tired than normal, itching in the genitals, and with wounds taking a longer time to heal. There is also an urgent need to go to the toilet more often than usual, particularly at night. Some diabetes patients also report losing weight without undergoing a diet or weight loss program.
