Tabitha, I don't know what big difference there is within a few days on your dad's situation. When I lost about 10 pounds,my oncologist admitted me to hospital by order already. I was still in the middle of my treatment. I could neither eat nor drink. At least in the hospital, I was closely watched by nurses and doctors day and night. I was discharged after three weeks when my weight stopped dropping and could handle some congee and milk.
