Many of Dr. Berookim's patients suffer digestive issues, including bloating, because they're lactose intolerant. Try eliminating dairy for a few days, including milk, cheese, butter, and yoghurt, and see how you feel.
If your bloating goes away, it's an easy fix — avoid dairy and use these dairy-free alternatives instead. If you can't give up dairy, you can take Lactaid pills. These pills provide your gut with the digestive enzyme lactase, which is needed to break down the milk-sugar lactose.
