GERD causes are not always apparent, though generally the condition stems from a problem with a muscle situated at the bottom of your esophagus where it meets the stomach. This muscle is the lower esophageal sphincter (LES). The LES may be considered like a gate - it opens to let food into your stomach, and it closes to prevent any acid washing back up into your esophagus.
For people with GERD the LES has become weakened, allowing stomach acid to pass back into the esophagus, which is how GERD causes the symptoms of heartburn.
Other GERD causes may include:
There are a number of risk factors which are known to increase your likelihood of developing GERD. These are:
We can see then that GERD causes may seem varied but the underlying physical condition is a mechanical problem with the LES.
