Gastroesophageal reflux disease is a disorder that results from stomach acid moving backward from the stomach into the esophagus. The esophagus is the muscular tube that connects the mouth to the stomach by the way.
If your acid reflux and heartburn is worse at night, try raising the head of the bed. That way your esophagus is higher up than your stomach and less acid would trickle back up the wrong way. But before you start chopping off two legs of the bed, or put bricks under two others, adding another pillow or two could do the trick too.
It is worth cutting back on tomato based foods like chilli, pasta and pizza sauces with tomatoes in it as tomatoes are known to cause an increase in stomach acids, which in turn can trigger heartburn and GERD symptoms.

Summary : Everything you ever wanted to know about your heartburn
I began searching for educational materials on heartburn after I had lived with it for several years and had poured all kinds of antiacids into my stomach. This book is very informative, explaining the causes, treatments, and even the long-range effects of continuing heartburn. It educated me to where I was able to discuss my condition knowledgeably with my physician and had no "fear of the unknown" when it came time to begin treatment.

I cannot tell you enough how good this book is - after ploughing through trees of print, here is one that just gets to the point and is interesting as well. It is also set out so that you do not have to read the first half to understand one page near the end.
Very readable, even just for information. People without problems should find the details in this text interesting and good guidance.
People can change their diets to actually eliminate or reduce the effects of Acid Reflux. A proper routine can be made to reduce the problem which generally causes due to the irregular habits of eating or eating more junk food and also from excessive drinking. These bad habits cause a rise in the stomach acids, which in turn adds more pressure on the muscle that is trying to stop the stomach acid from escaping.
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.
