Frequent acid reflux when walking is mainly considered to be related to dietary stimulation, abnormal esophageal dynamics and peptic ulcer. 1. Dietary stimulation: In daily life, frequent overeating or consumption of spicy and stimulating food will cause gastrointestinal stimulation and trigger acid reflux. Walking and other exercises will aggravate gastrointestinal peristalsis, further aggravating the symptoms of acid reflux. 2. Abnormal esophageal dynamics: diseases such as pancreatic achalasia and reflux esophagitis can also trigger acid reflux. When walking, as gastrointestinal peristalsis intensifies, it can cause an acute attack, which in turn leads to the symptoms of acid reflux. 3. Peptic ulcer: diseases such as gastric ulcer can also cause acute attacks and symptoms such as acid reflux when walking. The appearance of such symptoms may also be associated with chronic gastritis, stomach cancer and other tumors. Patients are advised to seek medical advice to confirm the diagnosis and treat the cause.
