—such as vomiting involuntarily, blood flowing from cuts or boils, nocturnal emission, and similar occurrences that have no fixed time and therefore cannot be avoided. For that reason they were not deemed to conflict with the fast the way menstrual blood does.” End quote (25|251).

If she had a legitimate excuse, she is required only to make up the fasts. The same ruling applies to anyone who owes make-up fasts because she broke the fast on account of illness or travel; her case is identical to that of the woman who missed the fast due to menstruation, as detailed above.
