10 Diabetes Symptoms
Symptom #9: Blurred Vision
Excess sugar in the bloodstream can damage the blood vessels in the eyes, including rupture. It may also elevate fluid pressure in the eyes. This interferes with the functioning of the retina and the optic nerve, responsible for transmitting images to the brain, causing blurred vision. High blood sugar can also cause other vision problems like retinopathy, cataracts, glaucoma and diabetic macular edema.
While vision damage may be rectified if addressed early, if the diabetes treatment does not commence soon, the eyes may be further, and permanently damaged. New blood vessels may grow inside the eyes, blocking out light and images from reaching the retina and the optic nerve in particular. This worsens the vision problem and may even lead to blindness.
