I am still in the beginning phase. My consultation is on Feb 24 but I have done lots of researching. More so on the gastric bypass and some sleeve research. I suffer from gastritis and have been scoped many times. My ENT tells me that in my case gastric bypass will be better for me because I currently suffer from gastritis and heartburn . I also run low in Iron but my primary doctor says it wasnt alarming enough for her to say when I do have surgery that I had to choose the sleeve or that the sleeve was the best choice. I also have a problem with maintaining my electrolytes. With the bypass I would have be on top of this along with the common deficiencies that may occur. So, far two of my doctors believe I will stay on top of it. Its very important to get your blood monitored. I have been on you tube viewing videos of people who decided on doing the bypass instead of the sleeve because they already were dealing with gastritis. I have viewed videos of those who have gastritis before the sleeve and had no problems after the surgery and or mediciation helped it so much that it wasnt a problem . So it seems like a wait and see. I read that some doctors have done revision on some sleeve patients when the gastritis got too bad that medication didnt help and it was so bad they could not eat so it had to be revised. It just depends. You may not have a problem and that could be the case. No one can predict if gastritis will be a big or small problem after a sleeve. I would just continue to do more research to prepare yourself and be informed of all of the possibilities. I am still researching on the bypass and when I come across information on the sleeve I read that too. I want the bypass but I still keep research open to what the sleeve offers too. So every surgery has its pro and cons. Either way get all the information you can get so you can feel confident in your choice. The research continues for me.
