my mom had nissen surgery about a month and a half ago. two weeks later she developed an abscess and became septic. They had to go in and remove the infection. we almost lost her. she has been in the hospital now for 3 weeks. She gets so worked up when it is time to eat. She has no appetite and only can eat a few bites before she gets sick. She lost a good bit of weight. She is week. My question is why do you think she has no appetite, and cannot eat. Instead of mesh to close the hernia. He put I think he said pigs skin. does that MAKE a difference?
