Introduction

The normal range for high-density lipoprotein cholesterol (HDL-C) should be interpreted considering population differences. Reference standards vary for healthy adults, children, adolescents, and special populations. Reference values may slightly differ between testing facilities, and the specific range will be indicated on the report. If there are concerns about the results, consult a healthcare provider. Maintaining regular作息 (作息 should be translated as "sleep patterns" or "daily routines"), quitting smoking, and limiting alcohol consumption can also help support healthy HDL-C levels.

Generally, the normal range for high-density lipoprotein (HDL) cholesterol should be assessed considering population differences. The reference standards may vary for healthy adults, children and adolescents, and special populations. A detailed explanation is as follows:

For healthy adults, the ideal HDL cholesterol level is above 1.04 mmol/L, and levels between 1.04-1.55 mmol/L are also considered normal. Regular moderate-intensity exercise for 150 minutes per week, such as brisk walking or jogging, combined with a diet low in sugar and fat and rich in oats and fish, can help maintain HDL cholesterol within this range.

For children and adolescents, the recommended normal HDL cholesterol level is generally above 1.04 mmol/L. Developing healthy habits during this stage is crucial, including eating fewer fried foods and sugary beverages, consuming more fruits and vegetables, and ensuring adequate sleep to help maintain normal HDL cholesterol levels.

Patients with chronic conditions such as diabetes and hypertension are advised to maintain higher HDL cholesterol levels, often above 1.04 mmol/L, with some requiring levels exceeding 1.55 mmol/L. In addition to lifestyle modifications, these individuals should follow medical advice to manage their underlying conditions and regularly monitor their HDL cholesterol levels.

Reference values may vary slightly between different testing institutions, and the specific normal range will be indicated on the test report. If there are concerns about the results, individuals should consult a healthcare provider and adopt healthy lifestyle practices such as regular sleep patterns, smoking cessation, and limiting alcohol consumption to support healthy HDL cholesterol levels.

What does it mean to have low HDL cholesterol?

In general, low high-density lipoprotein (HDL) levels may be associated with factors such as lack of physical activity, obesity, hypothyroidism, hyperlipidemia, and diabetes. Patients are advised to seek timely medical evaluation at a hospital and receive appropriate treatment under a doctor's guidance. In daily life, it is important to maintain a balanced diet, ensure adequate intake of vitamins and protein, and consume more vegetables and fruits.

What does high HDL cholesterol indicate?

High levels of high-density lipoprotein (HDL) typically indicate that HDL levels in the blood exceed the normal range. HDL is considered a beneficial type of cholesterol that helps transport cholesterol from blood vessel walls and other peripheral tissues to the liver for metabolism and excretion. This process aids in reducing cholesterol deposition in blood vessel walls and helps prevent cardiovascular diseases such as atherosclerosis.
