Have been fasting for the last 10 days or so due to ramadan. I usually break my fast with limited amount of greasy/oily food and fruits such as papaya. In the last few months, I have experienced indigestion, vomiting and severe diarrhea twice after having outside food. Recently, since I began fasting, I am noticing that I am suffering from excessive flatulence and sometimes watery flatulence. What can be the cause and should I be worried?
