FAQs About Stomach Bloating

Here are some frequently asked questions about stomach bloating.

Why do I have a bloated stomach after eating?

You may have abdominal bloating after eating if you have consumed a particularly gas-inducing foods. These include meats and cheeses and anything more difficult to digest that will leave a significant amount for bacteria in the gut to digest. Beans may also produce bloating as they contain compounds that are much easier for bacteria in the gut to digest and produce H2 gas from.

What foods are good to reduce stomach bloating?

Insoluble fibers like rice, carrots, certain types of beans and legumes, tomatoes, and live cultures like yogurt and kefir can reduce gas by slowing down digestion, helping establish a more preferential balance of bacteria in the gut and diluting out gas-causing compounds.

Why does my stomach bloat before my period?

Bloating of the stomach or abdomen is often attributed to both the swelling of the uterus before menstruation as well as the retention of fluids during the premenstrual phase due to changes in the relative amounts of progesterone and estrogen. Usually the excess water that builds up dissipates during the term of the menses.

Why does my stomach bloat without eating?

Bloating can occur without eating for individuals that drink substances that increase bloating like alcohol, carbonated beverages, or sugary beverages. It can also be significantly increased in individuals with slow small gut motility (the speed at which substances travel through the small intestine).
