Bloating is one of the symptoms of trapped wind, and you’ll often hear them spoken about almost interchangeably.
This is because bloating is usually caused by gas build up in the stomach that makes your stomach expand — essentially, trapped wind in your stomach.
It can happen for lots of different reasons, including indigestion, IBS, and constipation.
Some people also experience bloating around their period, when it’s caused by hormonal changes throughout their monthly cycle.
