Having trouble with heartburn? Well, research shows that you are not the only one suffering from this condition. In fact, studies indicate that approximately 1 in every 10 adults in the United States or an alarming 10% suffer every day from this condition and the numbers are expected to rise in the near future!

The occurrence of heartburns usually denotes that the person has a condition commonly known as acid reflux. Acid reflux, medically termed as "reflux esophagitis" or "gastroesophageal reflux disease" (GERD), is a condition whereby the contents of the stomach are regurgitated or are returned back into the esophagus.

What causes acid reflux?

To understand this disease, we must be aware of how our digestive system works. As food enters the stomach, it is acted upon by the stomach acids and various digestive enzymes whose primary function is to break down the food so that the body can use it. The partially digested food, which is now acidic in nature, is then transported to the small intestine for further digestion.

However, this is not the case in patients afflicted with acid reflux. Those with this condition have a weakened lower esophageal sphincter (LES) which makes the regurgitation or passing of acidic gastric juices back from the stomach and up into the esophagus possible. In some cases, the acidic gastric contents even rise up as high as the mouth of an affected individual.

Among the factors which may contribute to the development of acid reflux are obesity, pregnancy, delayed emptying of stomach contents and the excessive intake of fatty foods. Smoking and drinking increase the body's caffeine and alcohol load which are also known causes of acid reflux.

Acid reflux is not only painful and annoying. Frequent regurgitation irritates the lining of the esophagus, which may lead to ulceration and scarring. At worst, it may even lead to the development of esophageal cancer.

What are the other symptoms associated with acid reflux?

Aside from frequent and painful heartburn, a person suffering from acid reflux may have the following symptoms:

. Regurgitation or the rising up of partially digested food in the stomach back into the esophagus or at times, even as high as the mouth
. Chest pains
. Difficulty in swallowing

. Difficulty in sleeping after eating
