Many gastric bypass patients undergo bariatric surgery to alleviate and eliminate some of the symptoms of obesity. High blood pressure, an increased risk for diabetes and stroke, heart problems and heart failure are some of the effects of carrying excess weight, and gastric bypass surgery is often the only option for those who are severely overweight or obese. A new study suggests that gastric bypass surgery can reduce blood pressure significantly because this type of bariatric surgery helps to improve the efficiency of the kidneys after eating and drinking.
The thesis was developed by the Sahlgrenska Academy at the University of Gothenburg and points to the link between the digestive tract, kidneys and renal elimination. Researcher Peter Hallersund from the Sahlgrenska Academy states, "My research shows that this elimination of urine starts already when salt and water reach the upper part of the digestive tract…So there’s a link between this part of the body and renal elimination.”
1,750 patients were involved in the study, and either underwent gastric bypass or gastric banding surgery. The results of the study show that the more urine is created after gastric bypass surgery than after gastric banding surgery, primarily because food and drink completely bypass the upper part of the digestive tract and relieve the kidneys from working hard to process everything. As a result, blood pressure is reduced and the patient may experience a better state of health overall.
Gastric bypass surgery continues to be among the most popular types of bariatric procedures because it can help obese patients lose weight very quickly. This procedure involves disconnecting the stomach and a part of the small intestine so that food goes directly into the small intestine, bypassing the stomach. Weight loss is achieved because of the resulting reduction in appetite and the inability to eat large amounts of food at any given time.
