Normal blood sugar range

The most important and only criterion for diagnosing diabetes is blood sugar. People with diabetes usually check their blood sugar when fasting and two hours after a meal. It is very important to check our blood sugar level in time, especially for diabetic patients. Changes in blood sugar levels can well explain changes in their condition. Let's take a look at the normal range of blood sugar values.

Many people want to know about the normal range of blood sugar values. Especially now that there are more and more patients with diabetes, many people are afraid that they will suffer from this disease, so they pay special attention to changes in their blood sugar. Everyone should understand the normal blood sugar value.

Generally, diabetics check their blood sugar: first, fasting blood sugar; second, blood sugar two hours after a meal. The normal range of fasting blood sugar is 3.9-6.1mmol/L (70-110mg/dL). If it is higher than 7.0mmol/L (126mg/dL), it is diagnosed as diabetes. The diagnostic standard for fasting diabetes is 7.0mmol or 126mg. You can see that there is a gap between the normal value and the fasting diagnosis of diabetes. Some people are neither normal nor have diabetes. We call this symptom impaired fasting glucose. In addition, blood sugar after meals is also very important. The normal blood sugar range two hours after a meal is 3.9-7.8mmol/L (70-140mg/dL). The diagnostic standard for postprandial blood sugar is 11.1mmol or above 200mg.

Experts say that knowing the normal range of fasting blood sugar can help us determine whether we have diabetes. Many people are very frightened after checking their fasting blood sugar levels and finding that their fasting blood sugar levels are high, fearing that diabetes will come knocking on their door. So, what are the causes of high fasting blood sugar?

One of the reasons for high fasting blood sugar is that the amount of exercise is significantly reduced:

The inability of insulin to fully and effectively exert its effect, excessive intake of sweets or sugary drinks, excessive obesity, and rebound hyperglycemia after hypoglycemia are called the SOMOGYI phenomenon. Drinking alcohol can cause both hypoglycemia and hyperglycemia. Medicines that can cause high blood sugar levels, such as certain cough syrups. After we figure out the cause of high fasting blood sugar, what we need to do is to control the total calories. The total calories should be determined based on the patient's nutritional status, weight, age, gender, physical activity, etc., so as to control blood sugar well.

There are two reasons for high fasting blood sugar:

Blood sugar is well controlled at night and no hypoglycemia occurs. Only for a period of time in the early morning is blood sugar very high, which is called the "dawn phenomenon." After hypoglycemia occurs at night, rebound blood sugar rises in the morning, which is called "Somogy reaction". Diabetic patients with "dawn phenomenon" can take oral hypoglycemic drugs during the day and add subcutaneous injection of intermediate-acting insulin before bedtime. This can achieve good therapeutic effects and control the high fasting blood sugar in the morning.

There are three reasons for high fasting blood sugar: insufficient dosage of hypoglycemic drugs:

Today we introduced the normal range of blood sugar values. Everyone should learn more about it. You should check your blood sugar levels regularly to avoid the occurrence of certain diseases. Nowadays, there are more and more diabetes patients. In our daily lives, we must be able to prevent the occurrence of diabetes in time and we must always understand our blood sugar levels.
