Many reasons: Some people can be allergic to ingredients in the pizza such as the tomato sauce. Some people have a lactose negative condition and cannot digest milk products (like cheese) well; this makes them bloat. Another possible cause could be gluten sensitivity or celiac disease. You need to ask your doctor to help you decide what is causing it and how to treat it.
