Many pregnant muslims women fast during Ramadan Since fasting during Ramadan is one of the five pillars of Islam and is a central part of Muslim culture, many women may fear a loss of connection with their communities or would feel guilty if they did not observe Ramadan. Each year, about 400 million out of 1 billion Muslims do this duty. Such tasks like eating, drinking, and smoking are forbidden from sunrise until sunset. Fasting during pregnancy has been always considered as a debatable condition.
