Causes And Cures For Passing Gas

4. Medication

FDA

There are some medications that cause stomach irritation, and sometimes this can result to gas buildup in the intestines.  This is especially true for persons with sensitive stomachs.  Some antibiotics, while intended to kill bad bacteria, will also kill good bacteria.  With the reduction of good bacteria, there will expectedly be a reduction in digestive system function.  Bacteria produce gas as they die off, plus undigested food ferment and produce gas.  These two factors combine to cause a gas buildup that will then have to be released, sometimes through a burp, often through a fart.
