Course Summary

Gastroesophageal reflux can occur in the first months of life, and it often resolves by age one. As individuals age, consistent symptoms of gastroesophageal reflux disease or heartburn can lead to complications. Successful management includes an understanding of the disorder, medication, dietary approaches, and education on managing symptoms. Several drugs are used for the treatment of gastroesophageal reflux disease. Patients should be investigated for symptoms and followed up through recommended diagnostic testing and treatment.
