Why does my mother abuse herself? It's cold in winter, but she wears spring and autumn clothes. There are vegetables and meat on the table, so she doesn't eat pickles. Two meals a day are salty.
This should be a psychological problem or a personal habit problem. Communicate with your mother first to show that you care about her, not interfere with her habits. If she doesn't accept it, you can go to a psychological adjustment institution, and you'd better take your mother with you. If mom doesn't want to, go to the psychological adjustment institution to explain mom's situation clearly and see if there is any good way.
