I interpret that question as "what can I do to stop smelling it, because she is old, stubborn, and is never going to change anything she does and will smell like this 'til the day she dies?"

I have a mother that is a Type-2 diabetic because for decades she refused to eat right or exercise like the doctors told her. She has tracked down every medication known to man to treat the symptoms just so that she doesn't have to give up junk food. And she will never change.
