Bread can cause bloating to you only when you have a sensitivity to one or other ingredients listed in the bread. Most of the time, it is gluten sensitivity, or in medical terms, it is known as celiac disease. It may also happen that you have weak immunity or a weak digestive system due to which you are not able to digest grains. If bread cause bloating to you, then it is highly possible that other grains may do the same. However, do not come to conclusions by reading online or listening to what friends or family are saying. You should consult the doctor and get to the root cause of your problem.
