4. Blurred Vision:
As we know, our body dilutes blood to remove excess sugar from the body, for which it uses the fluids present in the body. Sometimes due to the movement of fluids some fluid goes into the lenses of the eyes, causing the lens to swell.
Due to bloating, the shape of the lens changes and it is unable to focus properly. So, things look blurred.
Sometimes the opposite is also true, that is, the fluids present in the lens are pulled and even then, the shape of the lens deteriorates and things appear blurred.
