There are many reasons for the repeated elevation of blood lipids, the common one is the lack of good control of diet. Generally speaking, patients should be advised to have a low salt and low fat diet, eat more fresh fruits and vegetables, and do appropriate weight loss exercises, all of which can help to control blood lipids well. If the patient’s blood lipids are repeatedly elevated and the diet and exercise have been well controlled, then it is possible that the patient has a family history of hyperlipidemia, which requires lifelong use of lipid-lowering medication to control the blood lipids. For example, patients with hypothyroidism may have elevated blood lipids due to slow metabolism, so it is important to improve thyroid function while lowering blood esters to better control blood lipids. There are also some elderly people whose body metabolism slows down as they get older, which will gradually increase their blood lipids, so they need to gradually increase their exercise, but they cannot exercise strenuously for a long time, so they can take oral statins for a long time, which can not only improve atherosclerosis, but also lower blood lipids and stabilize arterial plaques, which is a secondary prevention drug for cardiovascular diseases.
