The sugar level


a Normal level of glucose in the bloodthe Level of sugar in blood - very important indicator in terms of human health. People don't usually think much about what an important role our body plays a glucose. And it represents the main source of energy for cells. This is its primary function and the secondary one is involved in the synthesis of building blocks of tissues.

the Energy that is used for the activity of the cells of the body, is released during the breakdown of glucose. And whether it is normal, depend on the biochemical processes in the cells, that is, for the human condition responds to the concentration of sugar in the blood.

What should be the blood sugar levels in a healthy person, in other words - what is the normal glucose level? Normal concentration of glucose within the boundaries of 3,3-5,5 mmol/l. during the day this figure will surely rise, as in the body from food carbohydrates do. The digestive process leads to absorption in blood simple carbs immediately after eating, and a little later they are joined and split to simple and complex carbohydrates.

Even a glass of sweet tea will quickly raise the glucose level, not to mention a full dinner. It is clear that after eating sugar increases significantly. And his normal 2 hours after eating - 7.8 mmol/L.

How the body manages during the day to maintain a normal glucose level? This helps the hormone insulin. A short-term increase of sugar does not affect health, but when the glucose level remains above normal for a long time, it causes throughout the body irreparable harm. Diabetes blood sugar cannot be regulated physiologically, and the person is required or enter additional insulin or taking glucose-lowering drugs. And in fact, and in another case requires must be assigned to a special diet in which simple carbohydrates are minimized.

People with diabetes should try to achieve the following results of glucose in fasting blood - to 6.5 mmol/l 2 hours after a meal - not more than 8,0 mmol/l. In these figures the risk of complications is minimal.

Why is it necessary to maintain correct blood sugar? How low he and high dangerous to humans. If its level will decrease to 3.3 and less than mmol/l, may disrupt brain activity and all organs. It starts a condition called hypoglycemia, weakness, incredible hunger, dizziness. Consciousness becomes confused, there is a trembling of the limbs. In its progression, that is, if it is not quickly increased, there may be a hypoglycemic coma.

No less dangerous and high glucose levels. If this condition is permanent, affected almost all human organs. Diabetes affects, primarily, the eyes, blood vessels, kidneys, and nervous system that leads to the development of angiopathy, retinopathy and nephropathy.

Most people are unaware that they have diabetes, because it is very insidious. Drops from 4 to 10 mmol/l of a person is not felt. And when, at any examination he has blood tests and found elevated levels, is that its diabetic "experience" is already quite high, and the disease gave irreversible complications.

this is why all people is important from time to time to check the level of sugar in their blood. If in the family the person was not diabetic, he should be examined at least once in five years. If you have relatives who are diabetics, need to take at least once every three years, preferably every year. If you have symptoms of this disease should immediately consult an endocrinologist, since the early diagnosis of diabetes allows them to adjust the power, to prescribe treatment and to avoid serious harm to health.
