Symptoms of chronic non-atrophic sinusitis include stomach pain, bloating, acid reflux and belching, loss of appetite, nausea, and vomiting. Chronic non-atrophic sinusitis is a relatively common gastric disease caused by congestion and edema in the mucosa of the sinus. The mucosal protective barrier of the sinus is easily attacked by gastric acid, which affects the peristaltic function of the stomach, and most patients suffer from stomach pain and bloating. The gastric glands in the sinus region are relatively abundant, and when inflammation of the sinus occurs, the gastric glands are stimulated, causing excessive secretion of gastric acid, which is accompanied by acid reflux and belching in the stomach. Chronic non-atrophic sinusitis affects the emptying of food by the stomach, causing food to remain in the stomach for a longer period of time, and the disease develops chronically, affecting the appetite of patients, many of whom experience a loss of appetite. In some patients, the condition is relatively severe, and the mucous membrane of the stomach wall will spasm and contract when stimulated, causing nausea and vomiting when the food in the stomach is squeezed.
