My mother is 80 years old and has early onset dementia and Osteoporosis. She has lost a lot of weight and is down to 93 pounds. She doesn't feel like eating and says she isn't hungry even when her stomach is growling. My sister and I have tried everything to get her to eat more including having her try Ensure and other similar drinks which she refuses. Recently we took her to the doctor who is very concerned about her weight loss. He also said that my sister and I should discuss whether or not to have surgery on my mother to remove an enlarged artery sitting on her abdomen. The doctor is keeping an eye on any development but is concerned because it could enlarge and burst and kill her. He said we could decide on surgery but because of her weight and the fact that she has no 'reserves' left for her body to fight against any kind of infection it might make the surgery risky. There is the possibility of infection, stroke or a fatal heart attack with any surgery but especially surgery on an artery in the abdominal area. He told my sister and I to think about it and discuss it with my mom (which isn't easy considering that her dementia makes her easily confused and frightened about everything). My concern is that her low body weight might make her surgery riskier than it normally would be. My fear, of course, is that if we leave it alone the artery could swell and burst and kill her instantly. I have no idea what to do.
