High Blood Sugar and Diabetes

Blood sugar control is at the center of any diabetes treatment plan. High blood sugar, or hyperglycemia, is a major concern, and can affect people with both type 1 and type 2 diabetes . There are two main kinds:

  • Fasting hyperglycemia. This is blood sugar that's higher than 130 mg/dL (milligrams per deciliter) after not eating or drinking for at least 8 hours.
  • Postprandial or after-meal hyperglycemia. This is blood sugar that's higher than 180 mg/dL 2 hours after you eat. People without diabetes rarely have blood sugar levels over 140 mg/dL after a meal, unless it’s really large.

Frequent or ongoing high blood sugar can cause damage to your nerves, blood vessels, and organs. It can also lead to other serious conditions. People with type 1 diabetes are prone to a build-up of acids in the blood called ketoacidosis.

Diabetes is a serious disease that can cause debilitating nerve pain.

Here's some helpful information:

If you have type 2 diabetes or if you’re at risk for it, extremely high blood sugar can lead to a potentially deadly condition in which your body can’t process sugar. It's called hyperglycemic hyperosmolar nonketotic syndrome (HHNS). You’ll pee more often at first, and then less often later on, but your urine may become dark and you could get severely dehydrated.

It's important to treat symptoms of high blood sugar right away to help prevent complications.

Your level is currently

If the level is below 70 or you are experiencing symptoms such as shaking, sweating or difficulty thinking, you will need to raise the number immediately. A quick solution is to eat a few pieces of hard candy or 1 tablespoon of sugar or honey. Recheck your numbers again in 15 minutes to see if the number has gone up. If not, repeat the steps above or call your doctor.

People who experience hypoglycemia several times in a week should call their health care provider. It's important to monitor your levels each day so you can make sure your numbers are within the range. If you are pregnant always consult with your health care provider.

Congratulations on taking steps to manage your health.

However, it's important to continue to track your numbers so that you can make lifestyle changes if needed. If you are pregnant always consult with your physician.

Your level is high if this reading was taken before eating. Aim for 70-130 before meals and less than 180 two hours after meals.

Even if your number is high, it's not too late for you to take control of your health and lower your blood sugar.

One of the first steps is to monitor your levels each day. If you are pregnant always consult with your physician.
