I am having surgery next week because of suspected endometriosis but I have noticed that for the last 4 to 6 weeks that I have been having some unusual symptoms. First, I have lost about 11 pounds without really trying. I have realized I have been eating less but because I seem to feel full much sooner than I normally would. I almost feel like I eat half as much at once as I used to and my stomach feel like its completely stuffed! I also have been having looser stools, regular diarrhea, and dull pains in my right abdominal area right under my rib cage. I seem to have the pains in the evening maybe once or twice a week...and there seems to be no correlation as to what I eat or anything else. At first I chalked it up to stress about the whole endo thing, but now I am not so sure. I am going to talk to my doctor about it obviously, but I just wanted a few other opinions.
