Type 2 diabetes

Glucose tolerance test for what?
To diagnose the following diseases:
Red prediabetes (latent diabetes, impaired glucose tolerance)
Est gestational diabetes mellitus (gestational diabetes)

Who can determine the GTT?
Elev Advanced Roger Glucose detection of latent diabetes
Fasting to detect latent diabetes with normal fasting glucose but with risk factors for diabetes (overweight or obesity, hereditary diabetes, hypertension, predisposition, etc.) +
Everyone 45 years old
Ge to detect gestational diabetes at 24-28 weeks of gestation

What are the rules of eating?
Glucose tolerance is tested, strictly on an empty stomach, 10-12 hours after fasting at night. You can get water during Ramadan.
The last evening meal should contain 30-50 grams of carbohydrates. On the eve of the study, at least 3 days before the test, you need to eat thoroughly, do not follow a diet and do not limit yourself to carbohydrates. In this case, your diet should contain at least 150 grams of carbohydrates per day. Fruits, vegetables, bread, rice, cereals are good sources of carbohydrates.
After taking blood on an empty stomach (first point), you need to drink a special solution. It is prepared from 75 g of glucose powder and 250-300 ml of water. The solution you need to drink slowly, not faster than 5 minutes.
The solution is prepared separately for children - 1.75 grams of glucose powder per kg body weight, but not more than 75 grams. You may ask: Are children tested for glucose? Yes, there are indications for GTT to detect type 2 diabetes in children.
After 2 hours of practice, i.e. after drinking glucose, a second blood sample is performed (second point).
Please note: You will not smoke during the test. Better to spend these 2 hours in a quiet state (for example, reading a book).
The test should be performed on venous plasma. Contact your nurse or doctor if you are offered a blood transfusion from a finger.
When doing GTT for pregnant women for 24-28 weeks, one more point is added to detect gestational diabetes. Blood sampling was performed 1 hour after the sugar load. They were shown to take blood three times: on an empty stomach, 1 hour later, and 2 hours later.

Circumstances when glucose tolerance should not be tested:
Ac Against the background of acute disease - inflammatory or infectious. During an illness, our body fights by activating hormones - anti-insulin. It may cause an increase in glucose levels but is temporary. An acute illness test may not be accurate.
Against the background of short-term use of efforts to increase blood glucose (lactococci, beta-blockers, thiazide diuretics, thyroid hormone). If you have been taking these drugs for a long time, you can get tested.

Glucose tolerance detection steps:
The first blood donation is made on an empty stomach in the morning. The time elapsed since the last meal is strictly controlled. It should not be less than 8 hours, so that consuming carbohydrates can be used, and not more than 14 so that the body does not start starving and absorbing glucose in starving amounts.
Glucose load is a glass of sweet water that needs to be drunk in 5 minutes. The amount of glucose is determined strictly individually. Typically, 85 grams of glucose monohydrate is dissolved in water, which corresponds to 75 grams of pure. The required weight for 14-18-year-olds is calculated according to their weight - 1.75 grams of pure glucose per kg body weight. With a weight above 43 kg, the usual adult dose is approved for obese people, the load is increased to 100 g. When administered interconnectedly, the portion of glucose decreases, which leads to its loss during digestion.
Repeatedly donate blood 4 more times - every half hour after exercise. By the dynamics of sugar reduction, it is possible to judge the violation of its metabolism. Some laboratories take blood twice - on an empty stomach and 2 hours later. The results of this kind of analysis can be incredible. If blood peak glucose occurs at an earlier time, it will be recorded.
