It is known to cause symptoms from asymptomatic to life threatening conditions. The management mainly depends on the severity of the disease and the size of the diverticulum and there is no specific treatment for an asymptomatic patient. We reported a case of 58-year-old gentleman who presented with dyspepsia secondary to gastric diverticulum. The diagnosis was made based on medical history and an outpatient Oesophagogastroduodenoscopy (OGDS). Patient was treated non surgically with proton pump inhibitors and prokinetics. https://acta.tums.ac.ir/index.php/acta/article/view/10975 https://acta.tums.ac.ir/index.php/acta/article/download/10975/5931
