To clarify this question, we must first understand some knowledge about blood lipids, because many people are not clear about blood lipids. Blood lipids are actually a general term for various fats in the blood. These fats have different types. Different types have different effects in the body, and their effects in diseases are different and effective. Different types of fat are different for the occurrence of hypertension.
Usually, lipid tests mainly include four types, such as total cholesterol, triglycerides, low-density lipoprotein cholesterol (ldl-c) and high-density lipoprotein cholesterol (hdl-c). Total cholesterol is total cholesterol in the blood, which contains Low-density lipoprotein cholesterol (ldl-c) and high-density lipoprotein cholesterol (ldl-c), high cholesterol is therefore divided into high cholesterol, high triglycerides and mixed hyperlipidemia. So when high blood lipids occur, be sure to know which one is high because they are slightly different from the body’s injuries.
For example, low density lipoprotein is called “bad cholesterol.” When it rises, it delivers excess fat to the vascular endothelium, which is the main cause of atherosclerosis. High-density lipoprotein (HDL) transports fat from the blood back to the liver for catabolism, which helps prevent atherosclerosis. Therefore, it is called “good cholesterol.” Triglycerides are fats transported by low-density lipoprotein or high-density lipoprotein. They cannot directly enter the vascular endothelium, so they can only be counted as “accomplice” of atherosclerosis.
With this knowledge in mind, let’s look at the relationship between hyperlipidemia and hypertension.
One of the causes of elevated blood pressure, because the blood vessels produce atherosclerosis, the blood vessels become thicker, not only the elasticity decreases, the lumen also narrows, the blood flow resistance increases, and the blood pressure rises. In the development of atherosclerosis, the role of low-density lipoprotein increased the most, several studies found that as long as the control of a certain degree of low-density lipoprotein (below 2.1 trend / L), other types of fat increased Triglycerides, for example, even if it occurs significantly reduce the risk of atherosclerosis, hypertension can greatly reduce the probability of occurrence.
Therefore, whether high cholesterol can cause high blood pressure, and also see which kinds of increase, if only triglycerides are elevated, and low-density lipoprotein is lower than the above-mentioned tendency of 2.1 L (note that this value is lower than the low-density lipoprotein limit The normal trend is much lower at 3.37 / L, which leads to a lower risk of high blood pressure, which greatly increases the risk of the opposite. You can take out your blood lipids and check the results of these two tests to assess your risk of hypertension.
Most importantly, for hyperlipidemia or active intervention, the intervention is not just about controlling the diet, but eating less meat and oil. For example, in fact, the rise of low-density lipoprotein in blood lipids, the dietary factor is only 20%. The main reason is that the diet is unreasonable, lack of exercise, irregular life, smoking, excessive drinking leads to abnormal lipid metabolism in the body, so the formation of good habits is the root cause of hyperlipidemia, in order to better reduce blood leads to high The risk of blood pressure.
