High Blood Sugar and Diabetes

How Is It Treated?

If you have diabetes and notice any of the early signs of high blood sugar, test your blood sugar and call the doctor. He may ask you for the results of several readings. He could recommend the following changes:

Drink more water. H20 helps remove excess sugar from your blood through urine, and it helps you avoid dehydration.

Exercise more. Working out can help lower your blood sugar. But under certain conditions, it can make blood sugar go even higher. Ask your doctor what kind of exercise is right for you.

Caution: If you have type 1 diabetes and your blood sugar is high, you need to check your urine for ketones. When you have ketones, do NOT exercise. If you have type 2 diabetes and your blood sugar is high, you must also be sure that you have no ketones in your urine and that you are well-hydrated. Then your doctor might give you the OK to exercise with caution as long as you feel up to it.

Change your eating habits. You may need to meet with a dietitian to change the amount and types of foods you eat.

Switch medications. Your doctor may change the amount, timing, or type of diabetes medications you take. Don’t make changes without talking to him first.

If you have type 1 diabetes and your blood sugar is more than 250 mg/dL, your doctor may want you to test your urine or blood for ketones.

Call your doctor if your blood sugar is running higher than your treatment goals.

How to Prevent It

If you work to keep your blood sugar under control -- follow your meal plan, exercise program, and medicine schedule -- you shouldn’t have to worry about hyperglycemia. You can also:

  • Know your diet -- count the total amounts of carbs in each meal and snack.
  • Test your blood sugar regularly.
  • Tell your doctor if you have repeated abnormal blood sugar readings.
  • Wear medical identification to let people know you have diabetes in case of an emergency.
