question: I have a protruding abdomen which has been getting bigger with the passing years. I am a 63 year old female and moderately active, I dont drink but I do look like I am 9 months pregnant. My weight has not increased but the size of my abdomen has. I have had several abdominal surgeries and have had a mesh inserted under my navel. I would really like to know what is causing this. There is a history of colon cancer in my family. Would this cause this increase in size?
