Hiatial Hernia & Two Ulcers - Pre-Op Question?

My WLS asked me to get a series of things done prior to them submitting my information for insurance approval. All are done now... and just have to send them the paperwork. One of the things on the list was an Upper GI because I had internal bleeding during the summer of 2005 (last summer) and was given 2 units of blood... and have been taking Iron. Here is my question. This recent Gastroscopy on Feb. 14th showed the hernia (large) with two ulcers - that were bleeding. The doctor said that since I am having WLS done - the surgeon can just repair the hernia during the operation. He said to continue with the iron and my Priolasac OT****il then. I am concerned about the internal bleeding and soon upcoming WLS. Also, the fact that I need Iron now... and many need Iron after WLS. Will that make me even MORE in need of Iron then? Has anyone else had this pre-exhisting condition prior to WLS? Is this a dangereous situation to be in for WLS? Hiatial Hernia & Two Ulcers - Pre-Op Question?
