Homocysteine 21.7 Is it serious and why?

Homocysteine 21.7μmol/L is serious and the cause needs to be judged according to the specific situation.

The normal value of homocysteine is 5-15μmol/L, while 21.7μmol/L is slightly higher than the normal value, indicating that the index is high. If it is only a simple index, it is usually considered to be related to bad eating habits. Because it is not accompanied by abnormal organic lesions and obvious discomfort symptoms, it is usually not serious. Special treatment is not needed. Pay attention to reasonable dietary collocation. However, if it is caused by pathological factors, such as coronary heart disease, myocardial infarction, cerebral infarction, etc., due to obvious discomfort symptoms, including precordial pain, chest distress, dyspnea, headache, etc., and may endanger life safety, clinically difficult to cure, usually more serious.
