Blood test for sugar, blood sugar level - Causes, symptoms and treatment. MF.
Diagnosis of "diabetes mellitus" is made to the patient on the basis of symptoms: increased intake and excretion of fluid in the urine, weight loss, increased blood glucose levels) and blood sugar analysis.
A blood test for sugar can detect diabetes in its two forms: insulin-dependent and insulin-dependent.
The analysis for sugar is prescribed for suspected diabetes mellitus in the presence of symptoms: constant thirst, sudden weakness, weakening of immunity. The blood test for sugar determines the level of glucose in the blood. The interval between the last meal and the time of taking the sugar test should be at least eight hours. Juice and tea in this case are also considered food.
The analysis for sugar is periodic in the event that a person is registered with an endocrinologist. Regular checks of glucose level contribute to the proper selection of diet, medications and a dose of insulin. Referral to the analysis for sugar can be obtained from your doctor.
How is the blood sugar test and preparation for the
analysis? Whichever method is used for blood sugar analysis, it is necessary to take it in the morning, most often( if the doctor has not agreed otherwise) on an empty stomach. Blood for the assay for sugar is taken from the finger, or from the vein simultaneously with blood sampling for other assays. The blood taken from the patient is sent to the laboratory for a series of tests.
Decoding of the blood test for sugar
In a laboratory blood test for sugar, the fasting blood glucose is determined, if it is equal to not less than 6.7 mmol / l when it is repeatedly determined, this indicates the presence of diabetes mellitus. The normal blood glucose level is 70-100 mg / dl or 3.8-5.5 mmol / l .
Even after getting good results, you should make sure that you do not have a predisposition to diabetes( that is, risk factors or other symptoms of the disease).The fact is that in some people the sugar in the blood taken on an empty stomach is within the norm, after the same meal it grows extremely fast. Tolerance( insensitivity) to glucose is one of the main symptoms of a dangerous disease - diabetes mellitus.
In controversial cases, as well as for the detection of glucose tolerance, is conducted with a sample of .To do this, take the blood on an empty stomach , the patient is given a drink of 250-300 ml of water, with dissolved glucose in it and every 30 minutes for 2 hours, blood is taken from the finger for laboratory analysis. In healthy people with normal glucose tolerance, fasting glycemia( blood glucose) is less than 5.6 mmol / L, less than 11.1 mmol / L between the 30th and 90th minute of the test, and less than 7 minutes after taking glucose, 8 mmol / l.
Impaired glucose resistance is fixed if fasting glycemia is less than 6.7 mmol / l, between the 30th and 90th minute corresponds to either 11.1 mmol / L and 11.8 mmol / L in 2 hours. Also study detailed tables with blood sugar norms for children and adults, women and men, on an empty stomach and after meals.
The so-called current blood test for glucose level has gained wide popularity. That is, the visitor of the laboratory does not abstain from eating when he is sent for research. In this case, if the sugar level exceeded the figure of 200 mg / dl( 11.1 mmol / l), most likely, this indicates the presence of the disease. You urgently need to see a doctor endocrinologist.
Before submitting a blood test for sugar, please check with your doctor how you need to prepare for the analysis, with different methods, the preparation for analysis for sugar varies.
Hyperglycemia and hypoglycemia
The blood sugar level is called glycemia , and the elevated level of sugar is by hyperglycemia .Hyperglycemia is the main symptom of diabetes mellitus. In the presence of hyperglycemia, the high sugar content in a person's blood must be reduced to normal. If the sugar in the patient's blood reaches high levels all the time, then this, in addition, worsens the well-being, but also leads to the development of chronic complications of diabetes. These complications affect, as a rule, the eyes, kidneys and legs of a diabetic patient.
In the treatment of insulin, under certain conditions, the blood sugar level may drop lower than is determined by the norm. This condition is called hypoglycemia .Diabetes patients usually raise the sugar content in the blood, eating something sweet in very small amounts. In healthy people, hypoglycemia often arises from improperly selected diets, alcohol abuse, carbonated beverages, flour and sweet, and also with strong physical overloads.
