Blood sugar, or glucose, is the main sugar found in the blood. It is derived from the food we eat and is the body's primary source of energy. Blood carries glucose to all cells in the body for use as energy. Diabetes is a medical condition in which blood sugar levels are too high.
An MCG system is especially beneficial for people who use insulin and have issues with low blood glucose levels. Healthcare providers rely on more than one blood glucose test to diagnose diabetes or any other condition. Before people develop type 2 diabetes, they usually have higher than normal pre-diabetic blood glucose levels, but not yet high enough to be diagnosed with diabetes. It can be adjusted to deliver more or less insulin depending on meals, activity level, and blood sugar level.Since food intake affects blood sugar, fasting blood glucose tests show a more precise picture of the baseline blood sugar level.
The most common use of a blood glucose test is to detect type 2 diabetes (T2D), which is a common condition. If your healthcare provider has asked you for a fasting blood glucose test, you won't need to eat or drink anything except water (on an empty stomach) for eight to 10 hours before the test. Your blood sugar goals may vary depending on your age, any additional health problems you have, and other factors.Driving with low blood sugar levels can be dangerous, so make sure to check your blood sugar level before getting behind the wheel. The A1C test is a simple blood test that measures average blood sugar levels over the past 2 or 3 months.
How much you can have and stay within your target blood sugar range depends on your age, weight, activity level, and other factors. For some people with prediabetes, early treatment can bring blood glucose levels back to normal levels.It measures the percentage of blood sugar bound to hemoglobin, the oxygen-carrying protein in red blood cells. Many things can cause high blood sugar levels (hyperglycemia), such as being sick, being stressed, eating more than expected, and not taking enough insulin. Your provider will also order a blood glucose test if you have symptoms of high blood sugar (hyperglycemia) or low blood sugar levels (hypoglycemia).
Low blood sugar (also called hypoglycemia) has many causes, including skipping a meal, taking too much insulin, taking other diabetes medications, exercising more than usual, and drinking alcohol.
