UPMC研究发现：肥胖患者体重减轻能够降低血压

 
 
一项最新研究发现，重度肥胖患者在胃旁路手术之后，血压出现显著而长久的改善。

Pittsburgh大学医学中心(UPMC, Pennsylvania, USA)体重控制中心的研究人员，分析了347例肥胖患者，开始体重指数(BMI)大于40，在1992-2001年期间在1992-2001年UPMC接受了胃旁路手术。半数患者在手术之前诊断为高血压，但是只有少数患者曾经接受过高血压治疗。在资料分析的时间点，术后18个月，他们的BMIs稳定在35左右，仍然属于肥胖。

在术前没有接受过手术治疗的患者，血压出现了显著下降，一直持续至术后18个月。在术前接受过高血压治疗的患者，在术后大约有1/3能够减少或者不再使用药物治疗。血压正常的患者术后血压没有显著改变。这些研究结果发表在20063月份的《手术档案》。
 

Blood Pressure Drops Along With Weight
 
A new study finds that severely obese patients may experience significant, long-term improvements in blood pressure after gastric bypass surgery.

Researchers at the University of Pittsburgh Medical Center (UPMC, Pennsylvania, USA) Weight Management Center analyzed data from 347 obese patients, with an initial body mass index (BMI) greater than 40, who underwent gastric bypass surgery at UPMC between 1992 and 2001. Half of the study patients were diagnosed as hypertensive prior to surgery, but only some of them were being treated for their hypertension. At the time of data analysis, 18 months after surgery, their BMIs had stabilized to about 35, still categorized as obese.
 
The patients who were not being treated for hypertension prior to surgery experienced significant blood pressure decreases that continued to remain low 18 months after surgery. Of the patients under active drug treatment for hypertension prior to surgery, about one-third were able to reduce or eliminate their blood pressure medications after surgery. The group of patients with normal blood pressure showed insignificant changes following surgery. The results were published in the March 2006 issue of the Archives of Surgery.
