How to test for diabetes
Predisposition to diabetes
The risk group for diabetes includes:
- people over the age of 45;
- people suffering from overweight;
- people who have diabetics in their family.
If you are in this risk group, then it is mandatory to regularly monitor blood sugar levels. This will allow to identify the initial stage of development of diabetes mellitus and thereby promptly start the appropriate treatment.
But even if you are not predisposed to diabetes, there are a number of risk factors and symptoms that you should pay attention to. These include a sedentary lifestyle, cardiovascular diseases, arterial hypertension, high levels of triglecerides, and low levels of lipoproteins. You should also check for diabetes in women, if gestational diabetes was found in their pregnancy, or they gave birth to a child weighing more than 4 kg.
Symptoms of diabetes are excessive thirst, constant fatigue, frequent urination, sudden weight loss, increased appetite and blurred vision.In addition, constant painful tingling in the limbs, infections of the feet or nails, thrush and irritation of the genital area should alert you. If your wounds do not heal for a long time, it also does not interfere with checking the level of sugar.
Blood test for glucose level
This analysis is done on an empty stomach, i.e. You must not eat or drink for at least 8 hours before donating blood. In case of strong thirst, you can drink some water, but it is better to just moisten the lips and mouth for relief. In addition to the glucose level, this analysis shows the level of cholesterol and enzymes produced by the kidneys and liver. All these indicators are very important. If high levels of sugar indicate the presence of diabetes, then the remaining data allow us to estimate how much the disease has progressed.
The blood sugar level is 70-99 mg / dl.
If the analysis showed a level from 100 to 125 mg / dl, then you will be diagnosed with prediabetes. This means that you are at risk for developing the disease. Prevent this by changing your lifestyle. Get rid of excess weight, follow a special diet, increase physical activity, etc.
An indicator of diabetes is the level of glucose in the blood above 126 mg / dl. To clarify the result and exclude laboratory errors, the doctor may order a second blood donation, as well as conduct additional tests that confirm or deny the presence of the disease.
Glucose Tolerance Test
This analysis requires training. Ideally, the subject should maintain a diet of at least 150 grams of carbohydrates for three days prior to blood collection. If you maintain a low-carb diet, your results will be underestimated. Also affects the performance of oral contraceptives, thiazide diuretic and glucocorticosteroids. All this should be excluded for a few days before the examination. 10-12 hours before the test can not drink alcohol, smoke and eat. A small amount of water is allowed.
In the morning on an empty stomach blood for sugar level is given. After that, the patient should drink a glucose solution, prescribed by a doctor, in 5 minutes. Walk 2 hours. Normal physical activity is recommended at this time. After the appointed time, donate blood again.According to the data obtained, the level of glucose and the presence of diabetes are assessed.
The rate is less than 140 mg / dl 2 hours after taking a glucose solution. This indicates a normal reaction of the body. If the glucose level is from 140 to 199 mg / dl, then the subject is given prediabetes, and above 200 mg / dl - diabetes mellitus.
