Gastroesophageal Reflux Disease and Bad Breath
Q: I have gastroesophageal reflux disease and have been taking over-the-counter omeprazole once a day for several years. My concern is that I have bad breath. Can this odor be caused by the medication or by the acid reflux itself? I would also like to know the symptoms of acid reflux and the other potential causes of bad breath.
A: There are many potential causes of halitosis, or bad breath. While most commonly caused by poor dental hygiene and/or gum disease, bad breath can also result from gastroesophageal reflux disease. Additionally, some medications used to treat reflux can “dry” the tissues inside the mouth and indirectly lead to mouth odor. In fact, one small but limited study released in 2006 on omeprazole rasied the possibility that the category of drugs known as proton pump inhibitors could lead to an overgrowth of bacteria, and subsequently, bad breath.
Common causes of bad breath
Finding the source of your bad breath and taking measures to minimize or eliminate the odor is important for many reasons, including personal well-being and your social life. That said, the most common causes of bad breath include the following:
A visit with your family dentist for a full dental and oral health examination would provide the expertise needed to diagnose and potentially eliminate the source of your problem. In the meantime, try these ideas to help minimize bad breath:
Reflux symptoms
While the cause of your mouth odor may very well be linked to gastroesophageal reflux disease, symptoms vary and are often dependent upon body type (whether you’re thin or obese), social history (if you’re a drinker or smoker) and personal medical concerns (such as diabetes or an autoimmune disorder). Additionally, if you eat just prior to going to bed or eat large meals instead of small ones, you might be contributing to your reflux symptoms. Food choices like chocolate, peppermint, fatty foods and caffeinated drinks can also play a role.
The following symptoms can occur with other medical conditions, including heart disease, and should be discussed with your doctor. But in general, gastroesophageal reflux disease symptoms include the following:
Putting it all together
If you have been taking gastroesophageal reflux medication for several years, it’s important that you undergo a full medical evaluation. This disease may cause a narrowing of the esophagus, as well as a pre-cancerous condition known as Barrett’s esophagus. There’s also the potential that it can lead to an infection of the lungs known as aspiration pneumonia. A visit with your physician may indicate the need for specific tests such as an upper endoscopy or barium swallow radiograph.
