Patient discussion about Megace.

Q. What do you think are the chances of an 85 year old lady that gained a lot of weight recently to lose it? She takes hormones (megace) for cancer treatment which make her hungry. She gained about 20 Kilos in the last two years. She needs to lose it. Any ideas what is the best way to handle this problem and where can I find a good dietitian that can come to her place and support her. She lives in Jerusalem, Israel.
