For adults, the normal value of total cholesterol is between 2.9 and 6.0 mmol/L. If the total cholesterol is within this range, the patient is considered to have normal cholesterol. If the total cholesterol is 6.2 mmol/L, the patient is considered to have mild hyperlipidemia, also known as hypercholesterolemia. In this case, patients should change their daily habits, such as eating less cholesterol-containing foods, such as egg yolks, animal offal, animal fats, and seafood squid, because these foods contain high cholesterol, and if patients consume them excessively for a long period of time, they may cause the possibility of hypercholesterolemia in patients. If the cholesterol content in the body is too high, it will further induce the possibility of the patient’s biliary system to develop stones, and the patient may further develop the possibility of gallbladder polyps. For patients with mildly elevated cholesterol, it is appropriate to consider taking deep-sea fish oil and other health care products for treatment, and usually pay attention to more exercise and moderately eat more food rich in vitamin C. Clinically, if there is hyperlipidemia, it is recommended to have a physical examination of the carotid artery ultrasound to find out whether there is atherosclerosis or even plaque formation.
