My 85 year old mother has lived with my husband and I the past 3 years. I have never seen an elderly person with this kind of appetite. She does have vascular dementia but unsure it would cause this. If I didn't monitor what she was eating, I think she would eat all day. To make matters worse, she doesn't have any teeth. When she moved in she had ill fitting dentures that she wasn't able to wear. We had a new set of dentures made and they do not fit properly either because she has too much bone loss.
All she likes to eat is junk. She thinks eating 3 or 4 hot dogs at a time is normal ?? She can eat half of a large pan pizza by herself. It's a chore to feed her. Drives me nuts !
However, I realize it would be bad if she didn't eat.
