Response: Obesity and hypertension are highly prevalent diseases and when they are associated,  cardiovascular risk is almost double over patients with obesity alone. 60-70% of hypertension in adults may be attributable to adiposity.

To address both problems, we designed the GATEWAY TRIAL to evaluate the efficacy of Gastric Bypass in the reduction of antihypertensive medications in obese patients using at least 2 medications at maximum doses.

After 1 year, results were very consistent. 83.7 % of the patients submitted to Gastric Bypass reduced at least 30% of the total number of medications maintaining a controlled blood pressure (<140/90 mm Hg) and 51% remitted from hypertension, defined by controlled blood pressure without medications. When we evaluated the reduction of the medication maintaining the Systolic blood pressure below 120 mmHg (SPRINT TARGET), 22.4% of the patients showed remission of hypertension.
