大量饮酒可引起直立性低血压

Body art from the West, male body is mainly a reflection of the strength of the United States. While the female body is mainly a reflection of the kind of a female-specific negative of tender.
Body art is static human form, does not contain sexual intercourse is exposed genitals or other to tease of limb movements. Good photographs focus on the human body is the use of light and shadow. The body was naked from the arts, the human body art is not carnal desire , vulgar. Accurately speaking, and now, the "body art" is not very precise. Art classification is based on the auditory,
美国衣阿华大学和梅奥医院内科Somers博士认为,饮酒可明显抑制直立时心血管系统的调节能力(Circulation 2000,101∶398)。

  即使是健康的年青人大量饮酒后,直立时亦可引起同样刺激,会使血压明显下降。

  Somers以14名年青健康志愿者为对象(男13例,女1例,平均年龄26岁),进行随机对照双盲试验,结果验证了酒精的影响。

  通常,当人体直立时,回到心脏的血液量急剧减少,但通过血管收缩可使血压维持,从而可适当保持流入脑部或其他脏器的血液量。如在1小时内饮用与2~3杯啤酒等量的酒精,则通常不会引起血压下降。

  大量饮酒者血压下降严重时会导致晕厥和意识丧失。老年人、糖尿病或心脏病患者虽有程度差异,但都有过直立时眩晕的体验,而饮酒造成的降压作用更加明显。因此,有心脏病、糖尿病等危险因素者和服降压药的老人,原来直立时就会感到眩晕,易发生血压降低,如果大量饮酒,晕厥的风险更大。
