I am 40 years old and found out I had a haitel hernia 3 years ago. I have extreme bloating where I look like I'm 7 months pregnant. I am of medium weight. The bloating is getting unbearable. I also have nauseau. My doctors told me it is Irritable Bowel Syndrome. I don't think it is. I think it's the hiatel hernia but they told me it wasn't anything to worry about, it was small.
