Homocysteine 20µmol/L, which is 15µmol/L above the threshold, is mildly elevated and generally does not require medication. Mild hyperhomocysteinemia does not usually require treatment with specific medications. Elevated homocysteine is mainly associated with vitamin deficiencies. It can be improved by adjusting lifestyle, mainly by eating more green vegetables and fruits, supplementing folic acid and vitamin B6. In addition, active control of blood pressure and blood glucose can help keep homocysteine at normal levels. For patients with hyperhomocysteinemia, it is necessary to seek medical attention to identify the cause and treat according to medical advice.
