Is it obligatory to make up for past years of fasting or to offer expiation, due to the inability to make up for days not fasted in Ramadan because she was occupied with her menstrual cycle, knowing that she is able to fast in Ramadan despite her illness?

Fasting that was broken due to menstruation or other reasons must be made up. It is not permissible to substitute it with expiation unless the illness is incurable. In that case, it is permissible to break the fast in Ramadan and substitute making up the fast with expiation.
