2. Reflux
You might notice that you have slight acid reflux and think nothing of it. Again, there are many different things that can cause reflux, and so you shouldn’t necessarily instantly assume that it is hernia. However, this is one of the early signs and when it presents with other symptoms on this list, then hernia is a likely explanation.
The reason for reflux caused by a hernia, is that the stomach is protruding upward and thus pushing the diaphragm and the chest. The diaphragm is a sheet of muscle that lines the top of the abdominal cavity and sits beneath the lungs and stomach, thus this can push the stomach and make food more likely to travel the wrong way up the oesophageal canal.
