Patients often ask, “I’m thin, but my blood lipids are high, could the labs be wrong?” But what’s wrong if I still have high lipids after retesting? High blood lipids are not exclusive to fat people, thin people can also get high blood lipids. If you have the test done in a regular hospital or medical check-up and strictly follow the precautions before the test, then the result is informative. Why do thin people also get hyperlipidemia? A. What are lipid indicators Lipid indicators mainly include the four items of blood lipids: total cholesterol, LDL, HDL, triglycerides. Among them, HDL is a good lipid, which can prevent cardiovascular disease, while the other three lipids are bad lipids, which can aggravate cardiovascular disease. Usually we refer to high blood lipids: one or more of total cholesterol, LDL and triglycerides are elevated. Second, the causes of high blood lipids in lean people 1, familial hypercholesterolemia “familial hypercholesterolemia” is a dominant genetic disease that occurs on the autosomes, with familial characteristics, although the patient is not fat, some even very thin, but very high cholesterol. The most characteristic clinical manifestations of the disease are elevated LDL levels, yellow tumors, corneal arch and early-onset coronary artery disease. 2.Lifestyle abnormalities There are many risk factors for high blood lipids, including smoking and drinking, unreasonable diet, lack of exercise, genetics, obesity, diseases and so on. If you are a thin person, but you still like to eat fried food, fatty food, or eat more steamed rice, but you are not fat. But not fat does not mean that the blood lipids will not be high, as long as you eat more of these foods, triglycerides will still be high, so if a lean person has high triglycerides also need to pay attention to diet. The reason why cholesterol and LDL are elevated in thin people is because most of the cholesterol and LDL comes from our own metabolism, and a small portion comes from dietary intake. Simply put, even if a lean person does not eat greasy food, meat, animal offal, etc., your cholesterol and LDL will be elevated if you are a metabolic abnormality with high cholesterol. Long-term smoking, dislike of exercise, long-term mental stress may cause the body metabolic abnormalities resulting in elevated blood lipids. It can be seen, if you exist in addition to obesity other risk factors, may also get high blood lipid. 3, liver function abnormalities liver, is the body’s largest “chemical processing plant”, involved in the metabolism and synthesis of various nutrients, such as fat, protein, carbohydrates, etc., in the liver under the action of the relevant enzymes, metabolism. If the liver is damaged, liver function will be abnormal, resulting in abnormal lipid metabolism, affecting the decomposition and synthesis of fatty acids, cholesterol, phospholipids, etc., resulting in imbalance of blood lipid metabolism in the body. 4, caused by taking special drugs (1) Some antipsychotics such as chlorpromazine can affect the activity of certain lipoprotein metabolizing enzymes and cause dyslipidemia, resulting in a significant increase in serum triglyceride and total cholesterol levels. (2) Oral contraceptives are synthetic steroid hormone preparations composed of estrogen and progestin in different proportions. Studies have found that LDL cholesterol and triglyceride levels are significantly elevated in people taking oral contraceptives; the effect on HDL depends on the ratio of estrogen to progestin contained in oral contraceptives. (3) Diuretics Long-term heavy use of diuretics dihydrochlorothiazide and chlorothiazide can increase the levels of total serum cholesterol and triglycerides. It will have a certain impact on the smoothness of blood lipids. High blood lipids are not exclusive to fat people! People who are thin in stature must also be careful about their elevated blood lipids. Do not eat and drink indiscriminately and lead a poor lifestyle, and be aware of your blood lipid profile through annual medical checkups. Generally speaking, there are no obvious symptoms of high blood lipids, but long-term elevated blood lipids can bring many hazards, inducing fatty liver, coronary heart disease, hypertension, atherosclerosis and other diseases, so once elevated blood lipids are found, timely intervention is necessary.
