High blood sugar can affect fluid levels in the eye and temporarily change the way the lens focuses. This may make vision blurry or cause eyesight to fluctuate during the day.
Some people notice that reading becomes harder, lights look strange, or their glasses seem less effective than before. In some cases, vision improves when blood sugar is brought under better control.
Blurred vision can also come from eye strain, dry eyes, cataracts, migraine, or other eye conditions. New or repeated vision changes should be checked, especially if they appear with thirst, frequent urination, or fatigue.
7. Increased Hunger
Feeling unusually hungry even after eating can be another possible sign of diabetes. When glucose stays in the bloodstream instead of entering the cells efficiently, the body may continue sending hunger signals.
