Eating lipid-lowering drugs with low blood lipids can be temporarily suspended, through dietary control of blood lipids, patients with clear cardiovascular and cerebrovascular disease, still need to continue to take medication. Patients with hyperlipidemia should be assessed for risk before treatment. For patients with simple elevated lipids and no risk factors for cardiovascular disease, the medication can be discontinued after the blood lipids return to normal, and the diet can be controlled in normal times to reduce the intake of high-fat foods and keep the blood lipid level within the normal range. For patients with high risk of cardiovascular disease, such as patients smoking, hypertension, diabetes and other risk factors, or has clearly occurred in cardiovascular disease, need to keep blood lipids at a lower level, after taking lipid-lowering drugs to reduce blood lipids, but still need to continue to take medication, otherwise the blood lipid level will rise again. Patients with hyperlipidemia should formulate a treatment plan under the guidance of a physician and decide on a specific cycle of medication.
