Gastric Bypass weight loss surgery has proven benefits, and now, preventing heart attacks and strokes can be added to the list. A new study of 4000 patients has shown that over a fifteen year period, weight loss surgery reduced the risk of strokes, heart attacks and heart related deaths. The surprise in the data was that the reduction in illness and death was not related to the amount of weight loss, but rather to the fact that surgery was successfully performed.
Doctors have found in the past that diabetes begins to be reversed almost immediately after surgery, well before significant weight loss has occurred. It seems that the body’s biology is positively affected by the surgery, and these biologic changes may account for the heart protective effects shown in the new study.
This new study comes on the heels of a 2007 report which demonstrated a link between weight loss surgery and drops in deaths from any cause, and a later study which demonstrated a powerful link between weight loss surgery and resolution of diabetes. Combining these three studies raises the question as to whether weight loss surgery criteria should be modified so that lower weight patients might take advantage of the positive effects.
