Last week, he participated in a regular physical examination organized by the unit. Originally, Lao Zhang was worried about his fatty liver or something, but the physical examination results showed that Lao Zhang's fasting blood sugar was as high as 7.8mmol/L. Lao Zhang knew that

" fasting blood sugar has reached 8.1mmol/L, blood sugar 12.4mmol/L 2 hours after meals, you are definitely diabetes !"

"How is it possible? My family has no history of diabetes, and I don't feel anything abnormal in normal times, so why do you get diabetes directly?"

Lao Zhang has been frightened recently. Because of busy work and overtime work every day, Lao Zhang often eats midnight snacks, which makes him become more and more obese. Last week, he participated in a regular physical examination organized by the unit. Originally, Lao Zhang was worried about his fatty liver or something, but the physical examination results showed that Lao Zhang's fasting blood sugar was as high as 7.8mmol/L. Lao Zhang knew that the fasting blood sugar of a normal person should not exceed 6.0mmol/L, so he hurried to the hospital for a follow-up examination.

After a series of examinations, Lao Zhang's fasting blood sugar had reached 8.1mmol/L, and his blood sugar was 12.4mmol/L for 12 hours after meals. After a series of detailed examinations, Lao Zhang was diagnosed with diabetes, and he was very puzzled. But the doctor said that some abnormal symptoms in the body indicate that blood sugar has risen. If you have these three symptoms in your body, you must be careful if there is something wrong with your blood sugar.

1. What is the blood sugar value? Diabetes

Diabetes diagnostic criteria are "three more and one less" (drinking more, eating more, urine, weight loss) diabetes symptoms and meeting one of the following three items, they can be diagnosed as diabetes;

① Fasting plasma glucose ≥7.0mmol/L;

② Random (any time of day) plasma glucose ≥11.1mmol/L;

③ Oral glucose tolerance test : Plasma glucose ≥11.1mmol/L 2 hours after meals.

And if the fasting blood sugar is between 6.1 and 7.0 mmol/L, and the blood sugar is between 7.8 and 11.1 mmol/L 2 hours after the meal, this can be diagnosed as impaired sugar regulation, which is a manifestation of early diabetes and should also be taken seriously!

2. Three physical manifestations, be careful of diabetes!

1. Very easy to hungry

In normal three meals, you won’t feel very hungry after meals. If you always feel hungry again soon after meals, it is very likely that your body is abnormal. Because the islet function of diabetic patients is destroyed, the ingested glucose cannot be completely absorbed and utilized by the muscles, and the muscles and organs will not receive energy supply and will cause a wrong feeling of hunger. If you eat full every meal and still feel a strong sense of hunger not long after, be careful if it is due to diabetes.

2. Numbness of hands and feet

About 40% of diabetic patients will have numbness of hands and feet, and some people will feel like they are walking on cotton. If there is numbness in hands and feet for unknown reasons, you must not ignore the blood sugar and urine sugar . Because diabetic patients have increased blood sugar, peripheral vascular lesions are easily triggered. This causes the patient's peripheral blood vessels to gradually become narrow and hardened, and the inner membrane becomes thicker and thicker, which will affect the normal blood circulation of the limbs. The hands and feet are the end of the limbs and are also the part where the blood circulation will eventually reach. Therefore, once the blood circulation is abnormal and the limbs are seriously lacking in blood oxygen supply, the patient may experience symptoms of limb numbness.

3. Skin itching

If the skin itching before going to bed is unbearable, the cause is unknown and unbearable, the itchy parts are generally concentrated in the hands, feet and calves. At this time, you should consider whether it is a risk of diabetes. According to research statistics, about 20% of diabetic patients will experience skin itching, especially large-scale skin itching. The main reasons for are as follows: diabetic patients have a high sugar content in their blood, and the water in epidermal cells will spread to tissue fluid and plasma, resulting in dehydration of epidermal cells and causing skin itching; the increase in glucose concentration in the skin will stimulate nerve endings and autonomic nerves, causing the patient's nerve function to be disordered, thereby causing skin itching; yeast infection will lead to mild skin color changes, itching, and scaly rash. Diabetic patients have a high risk of developing yeast infection, and the degree of infection is often more serious.When diabetic patients have too high blood sugar levels, excess sugar will be secreted in mucus, sweat and urine. These secretions will cause yeast to overpropagate and cause yeast infection.

If skin itching occurs for unknown reasons, blood sugar testing should be carried out in a timely manner to check for diabetes.
