Control of hypertension after roux-en-y gastric bypass among obese diabetic patients.
BACKGROUND
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.


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


METHODS
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.


RESULTS
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.


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