What causes bloating in the stomach?
You might be wondering what causes stomach bloating. There are dozens of different sneaky reasons you might develop a bloated stomach — allergies, hormonal imbalances, thyroid dysfunction, gut troubles and more. Show more text
Bloating itself is usually a problem with digestion. Making it more confusing, many different things can affect gut health, the ability to metabolize food properly and our body’s way of naturally eliminating waste. Because so many different factors can contribute to stomach bloating — including some that seem totally unrelated, like sleep or stress — it’s possible to become bloated any time of the day or month.
Contrary to what most people think, bloating is not the same as carrying around extra fat mass or even “water weight.” Fluids can’t actually accumulate in your stomach, although you might be bloated and have water retention in other parts of your body (like your ankles, face and feet) at the same time as having stomach bloating if you have a condition that’s causing both.
For many people, the cause of excessive gas in the intestines boils down to: inadequate protein digestion (causing some foods to ferment), inability to break down sugar and carbohydrates fully (certain complex sugar compounds need the presence of enzymes to be digested fully, yet people can be lacking these), and imbalances in gut bacteria. In the digestive tract, there are trillions of healthy and unhealthy bacteria that compete, and when “bad bacteria” outweigh the good for one reason or another, an imbalance can lead to a bloated stomach and excessive gas.
