When a person is bloating after eating bread it usually means that the person has a wheat allergy which causes the bread to make the person bloat.
If the bread continues to make you bloat then you should see a doctor and let the doctor know that bread makes you bloat then they can test you for wheat allergies.
A bloated stomach may actually occur because of a wheat sensitivity, which is also known as wheat intolerance.
It's usually nothing serious when you get bloating from bread but it's a good idea to get tested for the wheat allergy or wheat sensitivity.
If so you may need to stop eating bread or slow down on the amount of bread you eat.
