There are five heart disease risk factors you need to know – blood sugar (blood glucose) is one of them. But you can prevent or lessen the effects of heart disease by staying informed about your body and measuring your blood sugar levels at home. A blood sugar test measures the amount of a type of sugar, called glucose, in your blood. Glucose comes from carbohydrate foods which is the main source of energy used by our body. Normally, your blood glucose levels increase slightly after you eat. This causes your pancreas to release insulin so that your blood glucose levels do not get too high. But if they remain high over time they can end in diabetes. There are different types of blood glucose tests. They are done to check for diabetes, monitor treatment of diabetes, or determine if an abnormally low blood sugar level (hypoglycemia) is present. Today you are able to do some tests at home using a blood glucose monitor. Here you can find some of the most recommendable models.
