Bloating can be caused by too much gas in the intestines, although you can also feel bloated and have a normal amount of gas. You can also feel bloated if you have an intestinal disorder, such as irritable bowel syndrome (IBS), which makes you more sensitive to the presence of gas in your intestines.
A Honor Society of Nursing (STTI) answered. There are some medications that can cause bloating. Bloating is an enlarged abdomen caused by excess gas. A few medications contain sugars that some people cannot completely digest, which can cause excess gas and bloating. Other medications include ingredients that stop the enzymes in your body from digesting your food. Talk to your doctor about switching medications if you are taking any that are causing bloating.
