Must one pray and fast on days when there is intermittent bleeding due to polycystic ovaries, and what is the treatment for polycystic ovaries?

If the duration of the intermittent bleeding, combined with other bleeding, does not exceed 15 days, then all of it is considered menstruation, and she must refrain from prayer and perform ghusl (ritual bath) when it ceases. The intervening period of purity is considered a valid state of purity. However, if the duration of the intermittent bleeding and the bleeding thereafter exceeds 15 days, then she is considered to be experiencing istihada (non-menstrual vaginal bleeding). Doctors must be consulted regarding the treatment of the illness.
