10 Causes of Belly Bloat

7. Sudden Fiber Increase

Dietary fiber is critical to overall health, as it decreases appetite and encourages digestion. However, consuming too much fiber too soon can result in a bloated stomach. While it is important to eat fiber-rich foods every day, making an immediate switch after a period of low fiber intake -- whether due to poor eating habits or for a medical reason -- requires gradual increases over a few days or weeks. Any sudden increases are likely to result in digestive and bowel changes, which can include bloating.
