Weight reduction, moderate salt restriction and alcohol reduction are
effective in lowering blood pressure (BP), and are feasible interventi
ons for long-term management of hypertension. When used in combination
these non-pharmacological measures are significantly inferior to drug
therapy in anti-hypertensive effect. When they are implemented as a f
irst step in the treatment of mild hypertension, resorting to drug the
rapy only if non-pharmacological measures fail, anti-hypertensive drug
s can be avoided in about 40% of patients. However, BP control is agai
n significantly inferior with this strategy compared with drug therapy
without nonpharmacological advice. Those given advice on nonpharmacol
ogical measures may therefore have suboptimal protection against cardi
ovascular complications. This is particularly so when the threshold fo
r drug treatment is set at a DBP of greater than or equal to 100 mm Hg
, as many patients will be left untreated with DBPs between 90 and 99
mm Hg as a result of non-pharmacological measures. Non-pharmacological
treatment may thus stand between patients and anti-hypertensive drug
therapy, which nowadays is simple, well-tolerated, safe and proven eff
ective in preventing cardiovascular disease. The role of non-pharmacol
ogical therapy needs to be reconsidered.
