Guidelines on the timing of blood lipid testing: High-risk groups should undergo blood lipid screening as early as possible.

Don't wait until your condition worsens to check your blood lipids: Because many people still lack awareness of the dangers of hyperlipidemia, and because hyperlipidemia itself often presents with few or no symptoms, many neglect it. The disease is more likely to be discovered when it progresses to the middle stages, leaving patients unsure of what to do. To prevent this, if you have any of the following conditions: a family history of hyperlipidemia, obesity, hypertension, xanthoma, coronary heart disease, stroke, diabetes, kidney disease, are middle-aged or elderly, postmenopausal women, or have a long-term high-sugar diet, please have your blood lipids checked as soon as possible. Young adults should have their blood lipids checked every two years; middle-aged and elderly people should have them checked annually; high-risk groups and patients with hyperlipidemia should follow their doctor's instructions and have regular checkups.

If you experience dizziness, headaches, insomnia, chest tightness, shortness of breath, memory loss, poor concentration, forgetfulness, obesity, heaviness in the limbs, or numbness in the limbs, hyperlipidemia may be a possibility. People with these symptoms should take preventative measures. People falling into any of the following categories also need to have their blood lipids checked:

(1) Middle-aged and elderly men and postmenopausal women, who are also at high risk for coronary heart disease or atherosclerosis.

(2) Patients with hypertension, diabetes, obesity, or who smoke.

(3) Patients with existing coronary heart disease, stroke, or peripheral atherosclerosis.

(4) Individuals with a family history of coronary heart disease or atherosclerosis, especially those with early onset or early death in immediate family members, or those with a family history of hyperlipidemia, xanthoma, or xanthelasma.

(5) Children with hyperlipidemia should also be included in the list. Researchers on hyperlipidemia include children over 2 years old with high-risk factors for coronary heart disease in their blood lipid tests, including those whose parents or grandparents were diagnosed with coronary heart disease by coronary angiography before the age of 55 and those whose parents have hyperlipidemia.

For other healthy individuals, blood lipids can be checked every 3-5 years.
