Common Causes of Acid Reflux


Acid RefluxAcid reflux, which is occurs when stomach acid backs up into the esophagus, can be caused by numerous factors. Some of the common causes of GERD include; pregnancy, hiatal hernia, smoking and alcohol consumption, asthma, weak sphincter muscles in the esophagus, and medication.


Pregnancy is a common acid reflux cause in women who are in their 3rd trimester. This is because as the baby grows, the stomach is pushed up, causing the acid to go back in the esophagus. Most of the time, medication will not alleviate GERD symptoms in pregnant women; however, the condition should improve once birth takes place. Eating smaller meals throughout the day can help manage acid reflux caused by pregnancy.

Hiatal Hernia

The hiatus is a tiny opening in the diaphragm in which the esophagus goes through the stomach. A healthy hiatus fits just right, but in certain cases it can become loose and swell. When this occurs, some of the muscles in the stomach may bulge and turn into a hiatal hernia. This condition is seen in adults over 60 years of age in 50% of GERD cases.

Smoking & Alcohol Consumption

Another common cause of acid reflux is smoking and drinking alcohol. Smoking can cause acid reflux in many ways including;

* Decreasing the production of saliva, which is necessary for balancing levels of acid
in the body.

* Reducing reflexes in the throat muscles.

* Causing damage to the mucous membranes.

* Boosting the secretion of acid.

Not only does smoking and alcohol cause acid reflux, the combination also maximizes the risk of esophageal cancer.


It isn’t clear whether asthma is another cause of acid reflux or vice versa, but it has been determined that there is a definite link between the two conditions. Some people state that coughing or sneezing during an asthma attack triggers acid reflux, while others say it’s their medication that causes the symptoms. There are also people who believe that GERD triggers an asthma attack because of the acid that leaks back into the esophagus. When this happens, the nerves in the chest are stimulated and cause constriction of the bronchioles.

Weakened Esophageal Sphincter

The LES muscle plays an important role in maintaining stomach contents separated from the esophagus. It is in charge of opening and closing the bottom part of the esophagus so that contents can pass through. In order to work properly, different hormones and muscles need to interact. If the LES muscle becomes weak or damaged, it may not fully close, causing acid to go back in the esophagus. Factors that cause weak LES muscle include; drug use, medication side effects, certain foods, and health conditions related to the nervous system.


NSAIDs (non-steroidal anti-inflammatory drugs) are known to cause peptic ulcers as well as acid reflux in some people. These drugs can also worsen the condition in people who already have GERD. Some of the medications that can lead to acid reflux include; naproxen, ibuprofen, and aspirin. Although it isn’t anti-inflammatory, acetaminophen is a good option for people with GERD. It is not an NSAID, but it will decrease pain without causing acid reflux symptoms.
