6. Blurred Vision
High blood sugar can temporarily change the shape of the eye's lens, making vision appear blurry.
Some people notice their eyesight fluctuates throughout the day, especially when blood sugar levels are poorly controlled.
In many cases, vision improves once blood glucose is brought back under control.
7. Increased Hunger
Despite eating regular meals, people with diabetes may feel unusually hungry.
Because glucose cannot efficiently enter the body's cells, the brain continues receiving signals that the body needs more energy, leading to persistent hunger.
