High LDL cholesterol may not be inherited, but there are some that are. For those who have high LDL cholesterol due to heavy intake of high-fat food, alcohol abuse, strenuous exercise before checkups, obesity, etc., it is usually not hereditary. For those with transient high LDL cholesterol due to the above reasons, most of them will return to normal on their own after adjusting their diet, abstaining from alcohol, taking proper rest, and losing weight reasonably, so there is no need to worry too much. If high LDL cholesterol is caused by hepatitis, hypertension, coronary heart disease, nephrotic syndrome, diabetes mellitus, familial hypercholesterolemia, hypothyroidism and other diseases, there is a certain chance of heredity, which needs to be taken seriously. For people with high LDL cholesterol, further detailed examination should be done to clarify whether it is hereditary. For those who have high LDL cholesterol due to diseases, they should actively take treatment measures under the guidance of their doctors, and regularly consult their doctors for review, so as to improve the prognosis of the disease and enhance their quality of life.
