Is it obligatory for a woman to make up the days she missed in Ramadan due to pregnancy and childbirth, given that she is now afflicted with diabetes, and is she able to fast?

The sister who asked the question must make up the days she missed due to postpartum bleeding (nifas) before the next Ramadan. If she delays making them up without a valid excuse until the next Ramadan, then she must repent, and she must feed a poor person for each day she missed and whose making up was delayed, in addition to making up the fasts if fasting does not harm her due to her illness. However, if doctors determine that fasting is harmful and her illness is not expected to be cured, then the obligation to make up the fasts is waived, and she must feed a poor person for each day.
