Why does blood sugar increase?

Glucose is the most important source of nutrition and energy for our body. Entering the stomach food is then sent to the intestines, where it is completely digested. Glucose is absorbed into the bloodstream from food, and then diverges throughout the body and is spent on obtaining energy through which we can move, think and create. To make it clearer, the experts most often use the term "blood sugar", although it is quite clear that these are not at all identical concepts. The blood glucose level should normally be from 3.5 to 5.6 mmol / l, and after meals - 7.9 mmol / l. Blood sugar can differ depending on the technique of taking blood (venipuncture or blood from the finger), and its content may be different in the plasma and in the blood itself.

Reduced and elevated blood sugar have completely different symptoms and require different treatments, but they are caused both by a violation of the ratio between the level of glucose in the blood and insulin. Each person during the day the sugar level should fluctuate only in the minimum range. Stability of this process is due to the fact that it provides a number of complex regulatory mechanisms that take part in carbohydrate metabolism. A special role in this is played by endocrine glands, liver, nervous system. Violation of one of these links will inevitably affect such an indicator as blood sugar. The most frequent manifestation of carbohydrate metabolism in the body is diabetes mellitus, but the level of sugar in the blood can not at the same time indicate the severity of the disease. However, according to this indicator it is possible to talk about the prognosis for the patient for the nearest period of time.

Glucose comes to us in the body with various foods, as well as independently produced by the body in the muscles and liver. To deliver glucose to cells requires insulin, which is a hormone. If the body retains high blood sugar for several hours, then the body can develop complications, such as dehydration. Moreover, even a small hyperglycemia can lead to damage to the tissues of the brain, arteries and kidneys. If a person has an increase in blood sugar, then he should immediately seek help from doctors and seriously pay attention to this problem. Thanks to the normalization of nutrition, it is possible to cure diabetes and bring the sugar level to normal, this is evidenced by the stories of many people. To begin with, it is necessary to remove from the diet those foods that have a high glycemic index.

If the body is a violation of metabolic processes, then most often this is manifested in an increase or decrease in the level of glucose in the blood. Hyperglycemia is also harmful by the fact that it can cause severe metabolic disturbances in the body, and thus release toxic products of metabolism, thereby severely poisoning the body. An easy degree of hyperglycemia to the body can not do much harm, but when sugar exceeds all norms, a person can experience severe thirst, dry mouth, itching on the palms and feet, in the perineum. Because of this, frequent urination occurs, which leads to the release of sugar in the urine, the mucous membranes become dry and the itching grows. A person becomes sluggish and slowed, nausea, vomiting. This is the beginning of a hyperglycemic coma, which can result in a fatal outcome. The state of hyperglycemia is often characteristic of endocrine diseases, with prolonged such a state in the body, a violation of metabolic processes begins

The state of hypoglycemia is characterized by a decrease in blood sugar. It is not so dangerous for the body, but it can also lead to undesirable consequences. A sharp drop in blood sugar may be manifested as weakness. Cold sweat, trembling in the limbs. If the patient is not given something sweet, then the state of hypoglycemic coma may develop, the consequences of which are very deplorable. Everyone should control the blood sugar, this will allow him to stay healthy for many years.
