Reflux-Related Adult-Onset Asthma - Causes & Symptoms
The esophagus and trachea (windpipe) are in close relationship. GERD is common in patients with asthma and has been identified as a potential trigger for asthma, and patients with GERD may have asthma-like symptoms.
There is a mutual cause-and-effect relationship between asthma and GERD. In some situations, reflux disease can actually cause the asthma, particularly adult-onset asthma. In other cases the GERD can potentiate existing asthma, making it difficult to control. In addition, asthma symptoms such as cough and wheezing magnify the difference in pressure between chest (negative pressure) and abdomen (positive pressure), encouraging GERD.
GERD can cause asthma-like symptoms via two mechanisms:
Thus, it is important for physicians to consider the possibility of GERD when treating patients with lung problems.
Patient may have the common symptoms of reflux, including heartburn, difficulty swallowing and regurgitation.
However, as a result of the close relationship between the esophagus and windpipe, many patients may present with uncommon breathing symptoms including:
Chronic aspiration of gastric acid and bile (non-acidic fluid), which typically occurs at night when patients are lying down, can severely damage the lungs and vocal cords. Long-standing aspiration can even cause severe pulmonary disease such as pulmonary fibrosis.
