Non-drug therapy in prevention and control of hypertension.

Non-drug therapy is a very vital aspect in prevention and treatment of hypertension. The successive reports of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of Hypertension, WHO scientific report on primary prevention of essential hypertension and national High Blood Pressure Education Program's working groups report on primary prevention of hypertension have stressed on the non-drug therapy. Today a busy family physician does not spend enough time to explain to the patient various dietary and lifestyle modifications but straightaway prescribes the drugs. Every patient of hypertension from the stage of pre-hypertension to grade 2 hypertension should follow non-drug therapy. If non-drug therapy is strictly adhered, one can prevent cases of pre-hypertension from progressing to hypertension stage and one can reduce or stop the medications in Grade I (mild) hypertension. We have discussed the role of low salt, high potassium diet, role of caffeine intake, calcium and magnesium supplements, fish oil intake, cigarette smoking, alcohol consumption, role of physical exercise, stress reduction and bio-feedback, yoga, meditation and acupuncture. These recommendations regarding diet and lifestyle modifications should be targeted to population at large through public health authorities, non-government organisations and news media.
