IntroductionObesity‑related hypertension is a life threatening medical condition that significantly increases the risk of cardiovascular diseases and premature mortality. Effective treatment of obesity may be achieved by laparoscopic sleeve gastrectomy (LSG). This surgical method contributes not only to sustained weight loss but also to normalization of blood pressure.ObjectivesTo evaluate the effect of weight loss after LSG on partial or full control of blood pressure.Patients And MethodsA retrospective analysis of medical and clinical data of 305 patients who had undergone LSG was performed. The bariatric effect of LSG was assessed by calculating percentage of total weight loss (%TWL), percentage of excess weight loss (%EWL), and percentage of excess BMI loss (%EBMIL). Blood pressure status after surgery was categorized as partial or full hypertension resolution.ResultsA total of 143 patients (46.9%) were diagnosed with hypertension preoperatively with median (IQR) hypertension duration of 7.52 (1.88-13.16) years. Hypertensive patients were older (49 vs 38.5 years) and had higher prevalence of coexisting diseases (type 2 diabetes, dyslipidemia, and obstructive sleep apnea) than patients with normal blood pressure. During 1‑year follow up, 90 patients (63%) used lower doses of antihypertensive medications and 33 patients (23%) discontinued the therapy. Twelve months after the surgery, median (IQR) %TWL in the control group was 32.5% (28.1%-37.7%), while in the hypertensive group, 29.1% (25.9%-33.6%) (P <0.001); %EWL was 62.9% (53%-74.6%) and 54.8% (47.4%-68.2%), respectively (P = 0.001), and %EBMIL 73.9% (59.5%-91.2%) and 63% (55%-80.5%), respectively (P = 0.002).ConclusionsLaparoscopic sleeve gastrectomy is an effective method for the treatment of obesity‑ related hypertension. However, weight loss induced by LSG does not affect the blood pressure status after the surgery.
