Dizziness is due to anemia, frequent leg cramps are due to calcium deficiency, frequent tinnitus and hard of hearing are ear problems …… Many people have this perception, but in fact, these are incomplete or even wrong perceptions. All these symptoms are likely to point to the same problem – dyslipidemia. Dyslipidemia refers to plasma levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TG) that are above the normal range, or high-density lipoprotein cholesterol (HDL-C) that is below the normal range. Hypercholesterolemia is diagnosed when the total cholesterol level in the blood exceeds a certain concentration. Cholesterol exists in the blood mainly in the form of LDL cholesterol, and hypercholesterolemia can cause systemic atherosclerosis and even cardiovascular and cerebrovascular accidents. Hypertriglyceridemia has become an invisible life-threatening killer among hyperlipidemia. Blood triglycerides over 1.7 mmol/l is considered hypertriglyceridemia, and studies have shown that hypertriglyceridemia is an independent risk factor for coronary heart disease. Six signs indicate abnormal blood lipids, at this time must be timely medical care, under the guidance of the doctor standardized medication, even if the blood lipids to normal, can not arbitrarily stop the drug, otherwise blood lipids quickly back to the original level, and sometimes may rebound even higher. 1, dizziness is one of the common early symptoms of hyperlipidemia, especially in middle-aged and elderly people, who often feel not clear-headed after waking up in the morning, which can be improved after breakfast, and are extremely sleepy in the afternoon, but very awake at night. This point needs to be focused on. 2. Yellow, orange or brownish-red nodules, patches or rashes appear on certain parts of the body. More dark spots appear on the face and hands in a short period of time. 3, legs often cramp and often feel muscle tingling, or cold, numb calves. This is a sign of cholesterol accumulation in the leg muscles. This should be distinguished from calcium deficiency symptoms in particular. 4. Blurred vision, or loss of vision. This is the result of the blood becoming viscous and slowing down the flow rate, causing temporary ischemia and hypoxia in the optic nerve or retina. 5.Recurrent episodes of transient abdominal pain after a full meal can be seen as a result of mesenteric arteriosclerotic gastrointestinal ischemia caused by hyperlipidemia. 6. Frequent tinnitus and hard of hearing are also associated with hyperlipidemia, because hyperlipidemia makes the narrower inner ear vessels more narrow and blood supply is impaired.
