After I started taking Xarelto I have gained 25 pounds and my stomach is so bloated and distended I look like I am pregnant. It bloats and gets so hard that at times I feel like it is going to burst. I am a 79 year old woman. I have been to my gastroenterology doctor and he has performed several tests on my stomach and cannot find out why it is so bloated. I have tried dieting and even to the point of not eating but a 1000 calories a day and I cannot lose the weight.
