Yes, onion can create gas in the stomach, this is because onions contains a natural sugar called fructose. Our bodies cannot use fructose as energy, so it need to be broken down into simple sugars (glucose) which can be used as energy. During the brake down of fructose in the intestines, a gas is produced which occupies the stomach.
