Onion is an allium vegetable, all of which are gas forming. By cooking and chopping the onions you will reduce some of the gas formation it causes but this will not go away completely.

Onions contain fructose, which during digestion, breakdowns into the sugar causing gas. This happens specially with raw anions. If you have any digestion issue, avoid onions or take them cooked.

Onion is a food that can generate gases both in the stomach and in the intestine. You should limit onion consumption if you feel discomfort or intestinal pain.
