My mum has colon cancer and seems to have an obstruction higher up. Her belly has been very swollen, she has been sick and feels sick and in pain low down. The GP came out and agreed she seemed to have a blockage and that it was making her breathless as the diaphragm was pushed up. All she suggested was laxido but she already takes 2 ducolase a day. I think all this is not helping she has dioreah but still very bloated. I have started on fluids only diet. Should we drop the ducolase etc until her swelling and nausea improve? Thanks
