You must know the dangers of high blood sugar, and learn about it early!

Hyperglycemia, or abnormally high blood sugar levels, refers to a condition in which the blood sugar concentration in the body exceeds the normal range.

• The normal fasting blood sugar level is below 6.1mmol/L

• The normal blood sugar level two hours after a meal is below 7.8mmol/L

If it is higher than this range, but does not meet the criteria for diabetes, it means that the blood sugar is high (also known as prediabetes).

The following are the diagnostic criteria for diabetes in China ^[1] :

Typical symptoms of diabetes (“three mores and one less” – eating more, drinking more, urinating more, and losing weight) + any one of the following

• Random blood glucose ≥11.1 mmol/L;

• Fasting blood glucose ≥7 mmol/L;

• Oral glucose tolerance test 2 hours blood glucose ≥11.1 mmol/L;

• Glycated hemoglobin ≥6.5%.

1. High blood sugar: a health killer hidden in the details of life

In daily life, we may not be aware of our blood sugar levels, but it quietly affects our health. Imagine that when we frequently choose high-sugar and high-calorie foods, sit for a long time, or are too stressed to release effectively, our blood sugar levels may rise unknowingly, sowing the seeds of health risks for our bodies.

2. The dangers of high blood sugar: the health alarm has sounded

High blood sugar is not just a number, but also a potential health threat. Long-term high blood sugar status can damage blood vessels and the nervous system, increase the risk of cardiovascular disease, stroke, kidney disease, etc., and bring immeasurable impacts to our lives and work.

⚫ Increased risk of heart disease and stroke

Long-term high blood sugar levels can damage blood vessel walls and are a risk factor for atherosclerosis, increasing the risk of heart disease and stroke. Clinical data show that patients with high blood sugar levels are significantly more likely to develop cardiovascular disease than the normal population. ^[2]

⚫ Damage to the kidneys

High blood sugar can also cause serious harm to the kidneys. Diabetes is one of the main causes of kidney disease. High blood sugar can damage the kidneys and even cause renal failure.

⚫ Affects the nervous system

High blood sugar levels can also affect the normal function of the nervous system, leading to neuropathy and symptoms such as paresthesia, pain, and movement disorders. ^[3]

⚫ Vision loss

Long-term high blood sugar levels can lead to retinopathy, which can cause vision loss and even blindness.  ^[4]

3. In daily life, it is important to take preventive measures

Scientific management of blood sugar is essential for maintaining health. Regularly monitoring blood sugar levels and understanding your own blood sugar status can help detect problems early and adjust your lifestyle in time to prevent the occurrence of diseases.

Try to choose low-GI foods, such as whole grains, some vegetables and fruits, which can help stabilize blood sugar levels. In addition, controlling food intake and avoiding overeating are also effective ways to maintain stable blood sugar levels.

⚫ Moderate exercise

Exercise can increase the body’s utilization of glucose, which helps lower blood sugar levels while reducing insulin secretion. Both aerobic exercise and strength training can effectively help control blood sugar and improve the body’s metabolic rate. ^[5]

⚫ Regular medical check-ups

By testing blood sugar levels, timely identifying problems and intervening, it helps to avoid various complications caused by high blood sugar. Regular physical examinations can not only monitor blood sugar levels, but also assess other aspects of the body's health, providing a reference for comprehensive health management.

High blood sugar is a health problem that we need to pay great attention to. Through a proper diet, moderate exercise, regular physical examinations and small changes in daily life, we can effectively prevent and manage high blood sugar and keep the body healthy and stable. Let us pay attention to blood sugar management, make health the background of life, and lay a solid foundation for a better future.
