Blurred Vision
Blurry vision is often one of the first warning signs of diabetes. If your blood sugar is too high, fluid may be pulled from the lenses of your eyes. This may make it more difficult for your eyes to focus so things become blurry. A blurred field of vision, flashes, and spots of light will disappear once blood sugar returns to normal. If blood sugar levels are uncontrolled, blood gets thicker. Thicker blood pulls in more fluid from surrounding tissues including the lenses of the eye thus impacting the ability to focus. High blood sugar can cause the lens of the eye to swell. The ultimate consequence could be blindness.
