CAZZO, Everton et al. CONTROL OF HYPERTENSION AFTER ROUX-EN-Y GASTRIC BYPASS AMONG OBESE DIABETIC PATIENTS. Arq. Gastroenterol. [online]. 2014, vol.51, n.1, pp.21-24. ISSN 0004-2803.


Hypertension is a common disorder in general practice and has a widely known association with type 2 diabetes mellitus. Low adhesion to clinical treatment may lead to poor results. Obesity surgery can bring early and relevant resolution rates of both morbidities.


To describe hypertension evolution after Roux-en-Y gastric bypass in patients with type 2 diabetes mellitus.


Descriptive observational study designed as a historical cohort of 90 subjects with hypertension and diabetes who underwent Roux-en-Y gastric bypass and were evaluated before and after surgery.


It was observed a hypertension resolution rate of 85.6% along with markedly decrease in anti-hypertensive usage. Mean resolution time was 3.2 months. Resolution was associated with homeostasis model assessment – insulin resistance, preoperative fasting insulin, anti-hypertensive usage, hypertension time, body mass index and percentage of weight loss. Resolution of hypertension was not statistically associated with diabetes remission within this sample.


Roux-en-Y gastric bypass was a safe and effective therapeutic tool to achieve hypertension resolution in patients who also had diabetes mellitus.
