What does low LDL mean?

A low LDL generally indicates better health or good efficacy of lipid-lowering medications.
If a person with no previous history of hyperlipidemia is found to have a low LDL, it is a sign that the patient is generally in good health. This is because low LDL is good for the cardiovascular system.
Generally speaking, a high level of exercise, high consumption, and low fat intake in daily life will help to keep LDL at a low level, which will have a protective effect on the cardiovascular system.
If a person who has been diagnosed with hyperlipidemia and had a high LDL is found to have a low LDL after treatment, it means that the lipid-lowering drugs are more effective.
However, it is important to note that the lower the LDL, the better. Studies have shown that a level of less than 1.0 mmol/L may be due to liver disease. Because LDL is synthesized by the liver, liver abnormalities can often cause low LDL.
Therefore, low LDL needs to be evaluated by a physician based on the patient’s specific medical condition and appropriate interventions should be made.
