If you have diabetes, it's important to keep your blood sugar level within a healthy range. Lots of things can cause your blood sugar level to change like food, alcohol, exercise, sickness, and medications. Be sure to check your blood sugar often, and watch out for warning signs that your levels may be swinging too high or too low.

When your blood sugar drops too low, it's called hypoglycemia. This can happen when you skip a meal, take too much medication, or exercise more than usual. You may feel weak, hungry, anxious, cranky, or confused. Sweating, shakiness, headache, and blurred vision are also warning signs of low blood sugar.

When your blood sugar swings too high, it's called hyperglycemia. This can happen when you eat too much, are sick, stressed, or don't take enough diabetes medication. With high blood sugar, you might have nausea, dry mouth, blurry vision, being thirsty more often, or feeling tired.

Knowing the warning signs of a blood sugar swing will help you manage your diabetes and get you back in your target range.
