Hi i want to ask you about my mum. she just had her pancreas and spleen removed recently for her surgery. She is now home. She has no strength, she lose a lot of weight before the surgery and even worst now. She s eating good but after she eat she throw up. I want to ask you. Losing weight and very tired she always go to sleep after she just have food, because she said she is very tired. Losing weight and throwing up is normal?
