Hi Carol, I weighed 116 lbs (5'4" tall) before treatment and lost 16 lbs down to just 100 when treatment ended. Even though eating and swallowing were very painful, I insisted on feeding myself through mouth with 3 meals a day and a pack of milk in between meals. I had cereal as breakfast and fish congee for both lunch and dinner. I added different kinds of veggies in the congee to prevent constipation. I have no idea about the calories I got but I managed to increase weight gradually and returned to my previous weight in about 6 months. I am almost 3 years post diagnosis and I can eat almost all the food provided it is not too dry like nuts and chips or spicy. With small sips of water, even bread or cookies is easy to go down.I am happy with my weight now and need to exercise regularly to maintain it. Everyone's progress is different, some slower and some faster. Hope your sister is doing better and better.
Karen.
