Symptoms such as cardia relaxation, reflux and heartburn may indicate gastro-oesophageal reflux disease (GERD), which is a condition in which the reflux of gastric acid, pepsin, unconjugated bile salts, pancreatic enzymes and other refluxed material directly damages the oesophageal mucosa and presents with reflux and heartburn as typical symptoms, along with chronic cough and oesophageal spasm.
If these symptoms occur, prompt medical attention is required to identify the cause and treat it promptly.
