Learning objectives
- Explain endoscopy, ph testing, and manometry.
- Explain meal timing and treatment.
Endoscopy, pH testing, and manometry
Evaluation begins with symptoms and history. Endoscopy inspects the esophageal and stomach lining and may include biopsy. Esophageal pH testing measures how frequently and how long acid reflux occurs. Manometry assesses esophageal movement during swallowing. Other imaging or thin-camera examinations may be selected. These investigations answer different questions about exposure to acid, movement, and damage, rather than every test serving an identical purpose. Smaller meals and avoiding lying down soon after eating can help.
Meal timing and treatment
Smaller meals and avoiding lying down soon after eating can help. Weight reduction when appropriate, stopping tobacco, raising the head of the bed, and avoiding personal triggers can also improve control. Medicines may include antacids or prescribed acid-reducing treatment. Surgery is used in selected cases, not routinely. Management aims to reduce symptoms and protect the lining; persistent swallowing problems or other concerning changes require assessment.
Key concepts
- Lower esophageal closure and backflow
- Reflux occurs when the muscle at the lower esophagus fails to close properly or relaxes at the wrong time.
- Heartburn and warning symptoms
- Heartburn is burning in the chest or throat, but reflux can occur without it.
