It is important to distinguish between bloating and belching.

Bloating is the feeling that the abdomen is larger than normal. Thus, bloating is a symptom akin to the symptom of discomfort.

In contrast, belching (distention) is the physical finding that the abdomen is larger than normal. It can be determined by observations such as the inability to fit into clothes or looking down at the stomach and noting that it is larger than usual.

In some instances, bloating may represent a milder form of belching since the abdomen does not become physically (visibly or measurably) enlarged until its volume increases by one quart. Nevertheless, bloating should never be assumed to be the same as belching.
