My grandmother is in her late 70s and was recently diagnosed with Non-Hodgkins Lymphoma. She is now on chemotherapy, but during the course of her illness and her treatments which she has not completed yet, she has lost a lot of weight. She has a very small apetite and has difficulty consuming solid foods. She needs to gain weight but she doesn't have the apetite to simply eat more, what can our family do to make sure she puts weight back on? Diet suggestions? Health supplements of some sort?
