The main fuel for the body energy is simple sugar or glucose. It is transported from the liver or the intestine through the bloodstream to the cells in the body. The cells use glucose as the source of energy by the means of the hormone insulin. This hormone is responsible for the level of glucose in the blood. The pancreas is the gland that produces insulin.
The chart of the normal blood sugar levels serves to show whether a person has low, normal or high level of glucose in the blood. When a person has low or high blood sugar level, then he/she suffers from hypoglycemia (low blood sugar level), or hyperglycemia (high blood sugar level). There is also a chart of the high blood sugar levels. This chart is very helpful since it serves to show us whether a person has pre-diabetes, also called bordering diabetes, or diabetes.
Normal blood sugar level
In children, the normal blood sugar level ranges between 70 and 100 milligrams per deciliter, while in adults, it is between 70 and 150 milligrams per deciliter. The blood sugar level below 70 milligrams per deciliter is considered to be low blood sugar level in children as well as in adult. In children, the blood sugar level above 140 milligrams per second is considered to be high blood sugar level, while in adults the high blood sugar level is considered to be over 180 milligrams per deciliter.
Low blood sugar levels
Hypoglycemia is a condition marked by the level of glucose under 70 milligrams per deciliter in children, as well as in adults. This level can be less than 50 milligrams per deciliter in the case of insulin shock, or if the test is taken in the morning or before a meal. The people who suffer from hypoglycemia need extra sugar. Hypoglycemia occurs when the level of insulin in the blood is too low. This happens because the pancreas does not produce enough amounts of insulin, or when the body cells do not recognize insulin and do not respond to it.
High blood sugar levels
Hyperglycemia is a condition marked by the high blood sugar levels. The pre-diabetes blood sugar level in the morning or before a meal is between 101 and 126 milligrams, while two hours after a meal, it is between 140 and 200 milligrams per deciliter. The diabetes blood sugar level in the morning or before a meal is over 126 milligrams per deciliter, while 2 hours after a meal it is above 200 milligrams per deciliter.
