If one is sick, nursing or traveling, one is considered exempt from fasting. Any fasts broken or missed due to sickness, nursing or traveling must be made up whenever the person is able before the next month of Ramadan. According to the Quran, for all other cases, not fasting is only permitted when the act is potentially dangerous to one's health - for example; those elderly who are too weak to fast for extended periods of time, diabetics, nursing, and pregnant women, but this must be made up by paying a fidyah which is essentially the iftaar, dinner and suhur for a fasting person who requires such financial help.
