Type H hypertension refers to hypertension with elevated serum homocysteine (Hcy) (>10 μmol/L), the main causes of which are folate deficiency, reduced activity of methylenetetrahydrofolate reductase, and in most cases no symptoms. If you have H-type hypertension, you can use hydrochlorothiazide, metoprolol, amlodipine and other antihypertensive treatment, take folic acid to reduce homocysteine. At the same time, regulate diet, eat more food rich in folic acid and B vitamins as appropriate, control body weight, develop good living habits and keep a happy mood. If effectively treated under the guidance of a doctor and actively regulated, generally will not have an impact on life expectancy.
