A few years ago I had a lot of unexpected weight loss. I could eat at least 5000 calories a day, but the weight just fell off me. I totally took advantage of the situation
. Eating a lot of sweets which normally would pack the pounds on. Sadly after 3 months I started to regain weight.
I was sent to a cancer center where they did not find cancer, and no reason was found for the weight loss. I regain most of the weight. Since I was 19 I thought I had cancer, (won’t explain here). Couple years ago, a doctor agree to send me back to the cancer center due to my belief.
This time the proper test was done, the cancer was diagnosed. But the weight loss I experienced was not connected to the cancer I have. Go figure
As for telling your daughter, I would tell her. I found my children want to be kept in the loop and resent when they are not told things. They are adults and hate being treated like a children. But your family may be different.
