Blood Sugar
Monday, February 8, 2010
In medicine, blood sugar is a term that refers to the level of glucose in the blood. Blood sugar concentration, or serum glucose level, tightly regulated in the body. Glucose is channeled through the blood is the main source of energy for body cells.
Blood sugar levels are generally held on the limits of narrow throughout the day: 4-8 mmol / l (70-150 mg / dl). This level increased after meals and are usually located at the lowest level in the morning, before the meal.
Diabetes mellitus is the most prominent disease caused by the failure of blood sugar regulation.
Although called "blood sugar", in addition to glucose, we also find the types of other sugars, like fructose and galactose. However, only glucose levels are regulated by insulin and leptin.
Direct Influence of Blood Sugar Problems
When blood sugar levels dropped too low, which could be developed fatal condition called hypoglycemia. The symptoms are feeling tired, mental function declined, feeling irritable, and lost consciousness.
If the levels remain high, which is called hyperglycemia, appetite will be depressed for a short time. Hyperglycemia in the long term can cause health problems with prolonged also associated with diabetes, including damage to the eyes, kidneys, and nerves.
Mechanism of Blood Sugar Regulation
Blood sugar levels regulated through negative feedback to maintain balance in the body. Level of glucose in the blood are monitored by the pancreas. When the concentration of glucose decreased, because the consumed to meet the energy needs of the body, the pancreas releases glucagon, a hormone which targets cells in the liver (liver). Then these cells change glycogen into glucose (this process is called Glycogenolysis). Glucose is released into the bloodstream, to improve blood sugar levels.
If the virgin sugar levels increase, either because of changes glikoen, or because the digestion of food, another hormone released from the cell grains found in the pancreas. This hormone, called insulin, causing liver convert more glucose into glycogen. This process is called gliogenosis), which reduces blood sugar levels.
Type 1 diabetes mellitus caused by insufficient or do not produce insulin, while type 2 is caused by an inadequate response to insulin is released ( "insulin resistance"). Both types of diabetes result in too much glucose in the blood.
Low Blood Sugar
Some people feel drowsy or declining cognitive function several hours after eating, that they believed related to a decreased level of blood sugar, or "low blood sugar".
