A lot of people
don't understand what heartburn is, but it's real simple to explain. The
esophagus goes from the mouth down into the stomach. There's a connection
there and there's a valve that keeps the stomach acid in the stomach. The
stomach has lots of acid in it because it has to churn up the food in there and
do its job. Sometimes, that acid pushes up, but, that valve keeps it from
going into the esophagus. If you have a problem with the valve, or maybe
you lay down and it can leak in, it gets into that esophagus which does not
have a lining for acid and it hurts and you feel heartburn.
