Metformin in diabetes mellitus

Metformin is one of the best antidiabetic drugs to date. It is very effective in the treatment of type 2 diabetes, it can be taken in combination with insulin, and the dose is selected depending on the amount of glucose in the blood.

In the treatment of diabetes, it suppresses glucogenesis, without affecting the level in the blood of insulin. It also increases blood circulation in the liver, so that glucose quickly turns into glycogen.

In the treatment of the second type of diabetes, "Metformin" can be prescribed for life. If it is prescribed in conjunction with other hypoglycemic agents, it is necessary to monitor the level of glucose in order to avoid hypoglycemia. With a separate intake of the drug, hypoglycemia does not develop.

In addition, it is used in the treatment of obese patients, which often accompanies diabetes, as it suppresses the appetite and reduces the absorption of glucose from food in the digestive tract.

In the first type, the drug is used as a supplement to insulin and other diabetic drugs, it can be taken separately only with type 2 diabetes. At the beginning of treatment "Metformin" the intake of other hypoglycemic drugs must be stopped.

Treatment with Metformin also has a beneficial effect in the presence of metabolic syndrome and lipid metabolism disorders.

Metabolic syndrome is a condition of the body in which a number of factors are combined: a carbohydrate metabolism is disrupted, the patient suffers from arterial hypertension, obesity, etc. The syndrome accompanies an increased risk of developing cardiovascular diseases. This condition is based on insulin resistance, which, according to recent scientific studies, is closely related to diabetes and vascular damage.

As for lipid metabolism disorders, as a result of the conducted studies it was found out that the level of triglycerides, total cholesterol and LDL is reduced if you take tablets from Diabetes Metformin. The scientists' comments on this preparation also contain information about its effectiveness in the prevention of type 2 diabetes mellitus in violation of tolerance to carbohydrates.
