What Does Hyperglycemia Mean?
Hyperglycemia is the medical term used to describe high blood sugar. The condition is often associated with diabetes. Hyperglycemia is diagnosed through use of a blood test that measures the level of glucose in a person's blood.
A person is considered to have hyperglycemia if he or she has a fasting blood sugar level that is 130 milligrams per deciliter (mg/dl) or higher. A blood glucose level of 180 mg/dl when measured 2 hours after a meal also indicates hyperglycemia. Generally, a healthy person's blood sugar level 2 hours following a meal should be approximately 140 ml/dl, depending on what was eaten.
Some of the symptoms of hyperglycemia include excessive thirst, blurred vision, headaches, fatigue, frequent urination, and weight loss. Chronic hyperglycemia can lead to nerve and tissue damage. The symptoms of ongoing hyperglycemia include recurring skin infections, slow healing, nerve damage, digestive problems, and impaired vision. Hyperglycemia is sometimes referred to as high blood sugar or high blood glucose.
