Can gastric reflux trigger asthma?
Yes, gastric reflux can act as an irritant which triggers asthma. Reflux, properly known as gastroesophageal reflux, occurs when the liquids in the stomach pass up the esophagus, or feeding tube. Because these liquids are usually highly acidic, they can irritate and inflame the esophagus, and also the airways of the lung, should any of this liquid be aspirated. This irritation can trigger an asthma attack. Asthma flares caused by reflux are more common at night, for it is easier for material to pass up the esophagus when one is lying down. Some simple treatments to prevent reflux include raising the head of the bed, not eating close to bedtime, or using either antacids or medications such as ranitidine (Zantac) which reduce the amount of acid produced by the stomach.
