The dangers of elevated cholesterol include atherosclerosis, gallbladder stones and fatty liver. Atherosclerosis is the most common risk of elevated cholesterol. High cholesterol will penetrate into the inner wall of blood vessels, leading to the occurrence of arterial plaques, and prolonged elevation of cholesterol will lead to the occurrence of atherosclerosis, which may ultimately lead to cerebral infarction, myocardial infarction, and other diseases. Elevated cholesterol can also lead to lipid aggregation in the gallbladder, the formation of cholesterol stones, cholesterol stones can lead to acute cholecystitis, some patients may also trigger biliary obstruction, acute abdominal pain. Elevated cholesterol can also induce fatty liver, resulting in increased fat content in the liver, abnormal liver function, and may even lead to cirrhosis. Elevated cholesterol is very harmful to the human body, and should be strictly controlled by diet, if necessary, under the guidance of a physician to give treatment.
