Gastric asthma

Gastroesophageal reflux is a manifestation of gastrointestinal diseases. Due to the stimulation of gastric acid, it can cause diseases such as esophagitis and upper respiratory tract inflammation. When gastric juices are inhaled into the airways, an asthma attack can occur. Animal test results show that even inhalation of small amounts of gastric fluid can stimulate airway receptors and induce asthma. In asthma patients, the incidence of gastroesophageal reflux symptoms is 45% to 60%; the symptoms of gastric burning are about 77%, and those with acid reflux are about 55%. Any factor that can cause lower esophageal sphincter tone can increase reflux. But about 23% of patients are asymptomatic, also known as ldquo; silent reflux rdquo ;.
