For keeping good health, it is important that we maintain a safe blood sugar level. Safe blood sugar level would be the optimum range that safely provides the body with adequate amounts of energy. For the average person, it is 70 to 105 mg/ dl in a fasting state. Diabetes is diagnosed when the fasting blood glucose level is at or above 126 mg/dl. Glucose values vary depending on the time of day, our activity level and our diet. If there is any elevation in the monitoring of blood glucose level, then one must resort to lifestyle modification, diet and exercise. If these strategies are not adequate to control our blood glucose level, then physician may prescribe oral medicines or insulin.
On a daily basis, our body changees food into sugar and transports it into the Blood. Then insulin moves the sugar from Blood to Cells. The cells burn the sugar to make energy. This process occurs in our body all the time.
Before the onset of diabetes, our insulin worked fine. It transports sugar to the cells and also left a little to our blood.
Sugar left in our blood is called "Blood Sugar". Our blood sugar level can be measured with a simple blood test. It is measured in milligrams per deciliter (mg/dL).
For those who donot have diabetes, blood sugar stays in a :Safe Range" because Insulin keeps it there. Safe Range Level is from 80 mg/dL to 150 mg/dL.
The reason to keep our glucose level within a normal range is because an excess of glucose in the bloodstream causes various chemical changes that lead to damage to our blood vessels, nerves and cells. Each cell in the body has a function that requires energy and this energy comes primarily from glucose. The energy allows us to perform various tasks, including talking and walking. It allows our heart to beat and our brain to produce chemicals and signals that help us think, breathe, regulate our internal temperature and digest and absorb food. The body is a veritable industrial complex. But this complex is also quite delicately balanced. The very cells that process glucose and convert it to energy can be damaged by excess glucose. A lack of glucose is also extremely detrimental to the body and can have serious consequences - including death. Without a source of energy to fuel the vital functions of the body, these functions cease.
