Glucose is a major source of energy for most cells of the body, including those in the brain. It comes from the food you eat. Carbohydrates are found in fruit, cereal, bread, pasta, and rice. They are quickly turned into glucose in the body; this raises the blood glucose level. Hormones made in the body called insulin and glucagon help control blood glucose levels. Blood glucose can be too low or too high. Too much glucose can cause complicated issues.
Low insulin levels and/or insulin resistance prevent the body from converting glucose into glycogen (a starch-like source of energy stored mostly in the liver), which in turn makes it difficult or impossible to remove excess glucose from the blood.
Hyperglycemia, or high blood sugar, is a condition in which an excessive amount of glucose circulates in the blood plasma. Sustained higher levels of blood sugar cause damage to the blood vessels and to the organs they supply, leading to the complications of diabetes.
A blood glucose test measures the amount of a sugar called glucose in a sample of blood. As a general guide, test results after fasting for at least 8 hours, is as follows:
- Normal range: 4 to 6 mmol/l or 80 to 110 mg/dl
- Hyperglycemia: consistent range above 7 mmol/l or 126 mg/dl
- Hypoglycemic: consistent range below 4 mmol/l or 70 mg/dl
Chronic hyperglycemia can be measured via the HbA1c test. The definition of acute hyperglycemia varies by study, with mmol/l levels from 8 to 15.
Symptoms which may be associated with high blood sugar are frequent hunger, frequent thirst, frequent urination, blurred vision, fatigue (sleepiness), weight loss, poor wound healing, dry mouth, dry or itchy skin, tingling in feet or heels.
You can still lower your glucose through heart-healthy lifestyle changes, includes a heart-healthy eating plan, weight management, and regular physical activity. And, check out the glycemic index of your foods.
Healthy blood glucose, healthy body!
Clinical evidence has shown that essential nutrients help to support healthier body and blood glucose.
