Knowledge about blood sugar.


Knowledge about blood sugar

In medicine, blood sugar is a term that refers to the level of glucose in the blood. Blood sugar concentration, or serum glucose level, with a tight set in the body. Glucose which flowed through the blood is the main source of energy for body cells.

Generally, the blood sugar level stand on the borders of the narrow throughout the day: 4-8 mmol / l (70-150 mg / dl). This level increased after meals and usually are on the lowest level in the morning, before the meal.

Diabetes mellitus is the most prominent disease caused by the failure of blood sugar

Although called "blood sugar", in addition to glucose, we also find the kind of sugar, such as fruktosa and galaktosa. However, only glucose levels are regulated through insulin and leptin.

Direct influence of blood sugar problems

When the blood sugar level is too low to decrease, berkembanglah fatal condition that can be called hipoglikemia. Symptoms are feeling tired, a decreased mental function, feeling resentful, and loss of consciousness.

When the level stays high, which is called hiperglikemia, appetite will be depressed for a short time. Hiperglikemia in the long term can cause health problems that are drawn related to diabetes, including damage to the eyes, kidneys, and nerves.

The mechanism of blood sugar

Blood sugar level is set through a negative feedback to maintain balance in the body. Level of glucose in the blood monitored by pancreas. When the glucose concentration decreased, because the consumption of energy to meet the needs of the body, release glukagon pancreas, the hormone target cells in the lever (the heart). Then the cells glikogen this change into glucose (this process is called glikogenolisis). Glucose is released into the blood stream, to improve blood sugar levels.

When the blood sugar level increases, either because of changes glikogen, or because the digestion of food, another hormone that is released from the grain that there are cells in the pancreas. This hormone, called insulin, causing the heart to be more glucose glikogen. This process is called glikogenosis), which reduce the blood sugar level.

Diabetes mellitus type 1 is caused by not enough insulin or does not dihasilkannya, while type 2 is caused by the inadequate response to the insulin that is released ( "insulin resistance"). Both types of diabetes lead to too many is that there is glucose in the blood.
