Some of the significant causes of stomach bloating include swallowing air, constipation, gastroesophageal reflux, irritable bowel syndrome, lactic intolerance, overeating, and small bacterial growth. The most common cause of gas and bloating are constipation and eating fatty foods, which can perpetuate bloating.
Being bloated can cause you to feel full and your belly to swell up because of excessive gas located in the digestive tract. Bloating is routinely caused by eating gas-producing foods such as beans, and raw vegetables. Wearing too tight or too restrictive clothing can cut off the air supply and make you feel bloated.
