When the muscle that is supposed to prevent stomach acid from escaping up into the esophagus gets to weak to do its job and the acid keeps on gushing back to the esophagus, that is called acid reflux. It is a lot like heart burn but a lot more uncomfortable as generally there is much more acids and pepsins pushing back to the esophagus.

Summary : Excellent Book for Acid Reflux Sufferers
As a 4-year sufferer of acid reflux I found this book a mine of useful information. I now understand what Acid Reflux is and how to change my life style.
This book also gave me the ability to discuss the problem with my doctor, on a more equal footing.
It is not confirmed that chiropractic manipulations will help with acid reflux. In fact, some doctors don’t recommend chiropractic treatments for acid reflux at all. However, some patients claim that these types of manipulations help them greatly with their acid reflux symptoms. So, if you are interested in alternative therapies for your acid reflux, you can certainly give chiropractic manipulation a try and see if it helps you.
The most popular and largely used drug for this disease is PPI (Proton Pump Inhibitors), this is the drug which is generally prescribed by the doctors for relief from the pains causing due to the attacks of Acid Reflux. PPI helps in stopping the production of the acidic contents in the stomach which pushes into esophagus and cause acid reflux.

Summary : The book is about alternative medicine rather than heartburn
This book is not about heartburn. The first part of the book is about all manner of digestive problems, and then even about disorders purportedly related to digestive disorders. The second part of the book suggests that good diet (especially yogurt), enemas, and something called probiotics will cure all diseases, and therefore incidentally also heartburn (which thus has served only as a marketing come-on to lure in buyers). I believe there is much to be learned from alternative medicine, but this book actually offers very little rigorous (supported) information. For entertainment, and in closing, let me quote a tidbit. "Make the coffee enema by boiling six heaping tablespoons of ground coffee (not instant) in two quarts of water for fifteen minutes, cooling to a comfortable temperature, and straining..." It is probably a very good idea to let that boiling coffee cool a little before the anal consumption, but why is instant coffee not good, and how does this fix heartburn?
