Effects of Laparoscopic Sleeve Gastrectomy on Hypertensive Morbidly Obese Patients

Background: bariatric surgery is the standard way for obtaining a sustainable weight reduction in morbidly obese patients and it is a beneficial in lowering hypertension (both on the short and long terms)and improving other metabolic parameters. LSG is a relatively safe, simple and effective procedure which gained more popularity and became the most commonly performed bariatric operation. Aim: this prospective, randomized study designed to evaluate the outcomes of laparoscopic sleeve gastrectomy (LSG) on hypertensive morbidly obese patients. Patients and Methods: this prospective, randomized study was performed between January 2015 and December 2018 on 50 morbidly obese patients for whom a laparoscopic sleeve gastrectomy for treating morbid obesity was done in the department of general surgery, Al-Azhar University Hospital, Damietta. Results: the comorbidities among the 50 patients included hypertension (40), dyslipidemia (20), sleep apnea (18) and diabetes mellitus (15). These preoperative comorbidities significantly improved within 6 months after LSG and at the end of follow-up period which was one year after operation, nearly all comorbidities were resolved or improved.There was also a significant short-term effect on obesity and hypertension following surgical treatment and the decrease of blood pressure occured prior to significant reduction of weight. Conclusions: laparoscopic sleeve gastrectomy can improve and resolve elevated blood pressure in morbidly obese patients not only on the long term but also on the short term. It is a relatively safe and effective method not only for reduction of excessive body weight but also for improving and resolving many other comorbidities of morbid obesity.
