Hyperglycemia, or high blood sugar (glucose), is a serious health problem for those with diabetes. Hyperglycemia develops when there is too much sugar in the blood. In people with diabetes, there are two specific types of hyperglycemia that occur:
Fasting hyperglycemia is defined as a blood sugar greater than 130 mg/dL (milligrams per deciliter) after fasting for at least 8 hours.
Postprandial or after-meal hyperglycemia is defined as a blood sugar usually greater than 180 mg/dL. In people without diabetes postprandial or post-meal sugars rarely go over 140 mg/dL. However, occasionally after a large meal, a 1-2 hour post-meal sugar level can reach 180 mg/dL. Consistently elevated high post-meal blood sugar levels can be an indicator that a person has or is at high risk for developing type 2 diabetes
When a person with diabetes has hyperglycemia frequently or for long periods of time as indicated by a high HbA1c blood test, damage to nerves, blood vessels, and other body organs can occur. Hyperglycemia can also lead to more serious conditions, including ketoacidosis -- mostly in people with type 1 diabetes -- and hyperglycemic hyperosmolar nonketotic syndrome (HHNS) in people with type 2 diabetes or in people at risk for type 2 diabetes.
Diabetes is a serious disease that can cause debilitating nerve pain.

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.

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