That will depend on how bad you GERD is. If you have mild to moderate gerd meaning you only get gerd after eating certain types of foods. You are okay to have the sleeve most of the gerd is probably caused by being over weight. If your gerd is currently being treated with one antacid that controls it well, you are also okay to have the sleeve. If your gerd is severe, meaning you take two or more different types of antacids then the sleeve may make your gerd worse. You do not have to have a bypass. You can also have the sleeve with duodenal switch (SADI-S). Its safer than the bypass, and the weight loss is better. Look into it. I am in Altamonte Springs, if you have any more questions, stop by.
