Diabetes is a disease that stems from high levels of sugar in the blood. On average, a person needs only between 80-100mg/dL of sugar. But with the current increase of convenience store foods and snacks that are over-processed with high levels of sugar, you are probably consuming more than is necessary for your body to thrive.
This is bad for you because such foods encourage the onset of diabetes, which affects your body in a slow, degenerative manner. You might even be prediabetic for a long time without knowing it and then one day you become diagnosed with type 2 diabetes.
Diabetes adversely affects the brain, pancreas, legs, and eyes. Here are five ways that diabetes affects your eyes:
1. Puffy eyelids
Fluids follow sugar. Puffy eyelids result from fluid retention in your eyes. When you have too much sugar, you end up keeping excess fluid (oedema) in your eyes and other parts of your body.
When high sugar levels are present in the body, it can cause the walls of blood vessels to weaken, leading to leaking fluids and the formation of thin, fragile blood vessels. When the fragile blood vessels around the area where fluid drains out of the eye break, they clog the drainage and cause the pressure in the eyes to rise, ultimately leading to glaucoma.
High levels of sugar will also cause your proteins to misfold themselves, and this causes the lenses of your eye to turn opaque (cloudy).
High blood sugar also destroys blood vessels that surround the nerves of your eye. This cuts off oxygen to your nerves and, in the long run, destroys the nerves, which will leave you blind.
5. Dry eyes
By now you know that Vitamin A is good for your eyes. But did you know that your body needs Zinc to process Vitamin A? But that isn’t all, one of the leading causes of zinc deficiency is not the lack of zinc in the foods you eat, but the high levels of sugar in your blood. This causes the malabsorption of Zinc which causes the no absorption of Vitamin A, and this causes your eyes to become dry.
Your entire body functions optimally when it works the way it should, with little or no external interference. When one part of the body is affected, most likely all parts will be too. So, to minimize adverse effects on your body, always schedule eye examinations as part of your regular yearly check-up.
