To determine whether your blood sugar is normal, you need to measure it by drawing venous blood.
Patients with diabetes generally have certain signs. If the following conditions occur, you may develop diabetes.
1. Hunger, dry mouth, polyuria
Without obvious inducement, you eat more and have a better appetite, but you feel hungry again soon after eating, or you haven’t eaten yet. Obvious hunger during mealtimes. Because you will become more and more thirsty when you urinate more frequently, you will become thirsty and drink more and urinate more.
2. Weight loss
In a short period of time, there was no obvious reason for weight loss, about 9 to 10 pounds.
3. Blurry vision
When diabetes has elevated blood sugar, vision may be blurry or there may be black spots in front of the eyes, like mosquitoes flying around.
4. Other symptoms
General fatigue, or accompanied by dizziness and headache. Some people suddenly develop dry skin and itchy skin under the neck and armpits. Women are prone to vaginitis. A small wound on the body will take a long time to heal.
Diagnostic criteria for diabetes
Two consecutive times of fasting blood glucose greater than 7.0 mmol per liter
Two hours after a meal blood glucose greater than 11.1 mmol per liter
Or the random blood sugar is greater than 11.1 mmol per liter
Normal blood sugar
Normal blood sugar, fasting blood sugar, 3.9~6.1 mmol per liter, two-hour postprandial blood sugar , not exceeding 7.8 mmol per liter.
Prediabetes
Fasting blood sugar exceeds 6.1 mmol per liter, and blood sugar two hours after a meal exceeds 7.8 mmol per liter, but has not yet reached the standard of diabetes is called prediabetes symptoms.
Diabetes examination
1. Fasting blood glucose
Suitable for ordinary routine screening to detect diabetes. Fasting blood glucose refers to after 9:00 pm. Stop eating.
2. Glycated hemoglobin
It can be used in conjunction with fasting blood sugar to detect diabetes more sensitively. And it can monitor the average level of blood sugar control in the past three months.
3. Glucose tolerance test
For those whose initial test results show abnormal blood sugar, but it is still unclear whether they have diabetes, a glucose tolerance test is required.
The glucose tolerance test requires drinking 75 grams of sugar powder specially prepared by the hospital on an empty stomach, and then monitoring the blood sugar level for one and two hours. If the blood sugar is greater than 11.1mmol/l, diabetes can be diagnosed.
People at high risk of developing diabetes
Age over 40 years old, have a family history of diabetes, are obese, suffer from high blood pressure, hyperlipidemia, and cardiovascular and cerebrovascular diseases.
