Is it obligatory to make up two months of Ramadan or just one, if fasting for two months was prohibited due to a doctor's prescription of "insulin" resulting from diabetes during two consecutive pregnancies?

Whoever missed two months of fasting must make up those two months: one month for the previous Ramadan (definition) and one month for the current Ramadan, based on the Almighty's saying: "then a [like] number of other days." An insulin injection does not break the fast of a fasting person. Whoever delays making up for Ramadan without a valid excuse until another Ramadan begins, must make up the missed fasts and feed one poor person for each day.
