8. Blurred vision
Abnormally high blood glucose levels can cause changes in the eyes, altering the shape of the lens which then results in blurred vision. In addition, seeing occasional “flashes” of light and seeing “floaters” may also be a warning sign. Fortunately, vision problems like these are often reversible after blood sugar levels are returned to normal levels. Failure to address these symptoms could cause permanent damage as well as blindness.
