How can I tell the difference between low and high blood sugar, and what should I do for each?
Type 2 diabetes means your blood sugar is too high. Signs can include increased thirst and urinating more often. You may feel tired or have blurry vision.
Type 2 diabetes means blood glucose — your blood sugar — stays too high. Signs can include increased thirst and urination. Hunger, tiredness, and blurry vision are other signs. You may also notice numbness or tingling in your feet or hands. Some people have wounds that are slow to heal. But many people have no symptoms at all. Symptoms can develop so slowly over years that you may not notice them. The A1C is a blood test that shows your average blood sugar over about 3 months. Your care team uses it to track your blood sugar. Your provider will tell you how often to check your blood sugar and what to do when you notice changes.
