I fared well through my treatments, only losing 4 lbs. Yet the recent terminal illness and subsequent death of my father 3 months out of my treatment, and the caregiving it required, caused me to lose another 10 lbs which I cannot seem to regain. I am eating fine--no problems there. My MO said that radiation therapy increases one's metabolism. This is the first I have heard of this. Was anyone else told this? The inability to gain the weight back while being able to eat anything is frustrating me. I know 10 lbs. doesn't sound like a lot, but I am pretty small.
