Acid Reflux (GERD): Causes and Treatments

Many people have to deal with mild acid reflux or heartburn from time to time. Also known as gastroesophageal reflux disease (GERD), it occurs when stomach acid flows back into the esophagus from the stomach. A circular band of muscles called the lower esophageal sphincter (LES) is located at the opening where the esophagus leads into the stomach, and normally, the LES is open only when food or liquid is being swallowed.

This valve prevents stomach acid from flowing back the wrong way, so if it relaxes or weakens at the wrong time, acid reflux can occur. As the stomach acid comes in contact with the lining of the esophagus, it can cause severe pain and discomfort that feels like a burning sensation in the chest or throat. Acid reflux can also cause the regurgitation a food and unpleasant liquid, and in some cases even make it difficult to swallow.

What triggers acid reflux?

GERD is a complex medical condition that can be triggered by many potential factors, some of which may occur simultaneously. That said, one of the most common factors with acid reflux is being overweight. And while the science is unclear about why excess weight is linked to GERD, one theory is that it puts pressure on the abdomen, which in turn puts pressure on the LES, causing it to weaken.

Certain foods and eating habits can also trigger GERD, including:

• Greasy, fatty foods. Foods high in fat, especially high in saturated fat, take longer to digest. That means the food stays in the stomach longer and the stomach produces more gastric acid, increasing the likelihood that it will flow backward through the LES.
• Spicy food. While the science is unclear, there is plenty of anecdotal evidence that spicy food can make the symptoms worse if you already have acid reflux. Because the acid irritates the lining of the esophagus, the tissue becomes raw so it’s like putting jalapeno juice on an external cut or scrape. Cayenne, chili powder, curry, and black pepper are among the foods that can cause problems.
• Caffeine. Whether it’s in coffee, tea, or soda, caffeine can cause the LES to relax, allowing other food and liquid into the esophagus. Additionally, caffeine can stimulate an increase in the production of stomach acid.
• Alcoholic beverages. Alcohol in any form can make it difficult for your body to clear acid out of the esophagus. This is especially true when you lie down after having a few drinks. Plus, if you mix alcohol with something high in acid, like certain fruit juices, it can make the acid reflux even worse.
• Overeating. When you eat a large meal to the point of feeling full, your stomach expands. This puts pressure on the LES and, if it happens repeatedly over a long period of time, causes long-term damage. Plus, large meals stimulate the production of more stomach acid.

What you should do.

Mild acid reflux can usually be managed with a few lifestyle changes and the occasional use of over-the-counter medications. Clearly, losing weight will help if you have a few extra pounds or more. Also, avoiding some of the known trigger foods will help bring the symptoms of GERD under control.

If you experience heartburn and it’s accompanied by pain in other areas of the chest, or in your arm or jaw, call 911 immediately because this could be signs of a heart attack. You should make an appointment with a physician if your symptoms are severe or if you have frequent episodes of acid reflux. For example, if you are taking OTC heartburn medication more than twice a week, you should see a doctor.
