2. Difficulties Swallowing
If you feel a scratching, clawing, and narrowing of your throat when attempting to swallow, Healthline notes that you may suffer from acid reflux.
The source explains that chronic reflux can lead to benign esophageal stricture, a condition that can result when stomach acid irritates and damages the lining of the esophagus with time, causing scar tissue and esophagitis (or inflammation) to develop.
3. Unexplained Pneumonia
Research from 2009 that was published in the National Institutes of Health notes a link between gastroesophageal reflux disease (GERD) that can trigger or worsen existing pulmonary diseases (i.e., chest congestion, asthma, and pneumonia).
The NIH study found that local irritation due to stomach acid backlash in the esophagus can result in abdominal pain as well as coughing, wheezing, and chest discomfort that develops as unexplained pneumonia in the lungs.
Like unexplained pneumonia, chronic breathing difficulties such as asthma can be the result of acid reflux, according to research from WebMD.
The source also notes that roughly 75-percent of treatment-resistant asthma patients also suffer with gastroesophageal reflux disease (GERD), which is why asthma patients are twice as likely to suffer from acid reflux compared to non-asthma patients.
5. Excess Saliva Production
I can’t speak for anyone else, but I usually associate the mouth watering with the tantalizing scent of fresh baked bread. On the negative side, the mouth can produce excess saliva associated as a warning signal that you’re about to vomit.
However, Dr. Joseph Murray, GI researcher and doctor with the Mayo Clinic, notes that excess saliva production can be a symptom of acid reflux as well. Dr. Murray explains that similar to when you’re about to vomit, with acid reflux the salivary glands are triggered due to irritation in the esophagus.
