High blood pressure is a serious health problem and a primary risk factor for both stroke and heart disease. Many studies have strongly assessed short-term effects as well as long-term effects of bariatric surgery on type2 diabetes mellitus, whereas little attention has been paid to the effect on hypertension. This review study was designed to evaluate the impact of Bariatric Surgery and weight loss on obese patients with hypertension, and whether the hypertension improved or resolved post-surgery. Relevant papers were searched using MEDLINE, Science Citation Index, Pub Med, and Clinical Evidence, by using the searched terms (Hypertension, Bariatric, Obesity, and Surgery). The association between weight reduction and Hypertension control is hard to analyze. And well-organized studies with a long term follow up are required to determine the effect of Bariatric Surgery and Hypertension control.
