饮酒是否会影响血压？
回答 Francisco Lopez-Jimenez 博士
饮酒过量会使血压升高到不健康的水平。一次饮酒超过三杯，血压就会暂时升高。反复饮酒过量则会令血压长期升高。
至于多少饮酒量才算过量，我们有必要了解饮酒过量的定义。
- 饮酒过量定义为女性在两小时内喝四杯或更多酒，男性在两小时内喝五杯或更多酒。
- 少量饮酒是指女性每天最多喝一杯，男性每天最多喝两杯。
- 饮酒过量是指女性每天喝三杯以上，男性每天喝四杯以上。
酗酒者适度减少饮酒量，即可令收缩压（血压读数的顶部数字）降低 5.5 毫米汞柱（mm Hg），并令舒张压（血压读数的底部数字）降低 4 毫米汞柱（mm Hg）。
高血压患者应避免饮酒或适度饮酒。对于健康成人，女性每天最多喝一杯，男性每天最多喝两杯。
一杯酒是指 355 毫升（12 盎司）啤酒、148 毫升（5 盎司）葡萄酒或 44 毫升（1.5 盎司）80 度蒸馏酒。
请注意，酒精含有热量，会导致体重增长。体重增长是高血压的一个风险因素。酒精可能会与某些降压药发生相互作用，还可能会影响体内的药物水平或增加副作用。
