T18.11

Clinical Causes: Gastroesophageal reflux disease (GERD): a chronic condition where stomach acid frequently flows back into the esophagus. Hiatal hernia: a condition where part of the stomach pushes up through the diaphragm into the chest cavity, facilitating reflux. Obesity: excess body weight increases abdominal pressure, promoting reflux. Dietary factors: consumption of fatty foods, caffeine, alcohol, and spicy foods can weaken the lower esophageal sphincter. Certain medications: such as muscle relaxants and antihistamines, which may relax the esophageal sphincter. Smoking: reduces the effectiveness of the esophageal barrier to reflux. Delayed gastric emptying: causes contents to back up and increases the chance of reflux.

Key Symptoms: Usually include the sensation of acid or food backing up in the throat or mouth (heartburn). Regurgitation of gastric contents, often described as a sour or bitter taste. Chest pain or discomfort that may mimic heart issues. Difficulty swallowing or a sensation of a lump in the throat. Coughing, hoarseness, or sore throat caused by acid irritating the vocal cords. Nausea or vomiting, sometimes with vomitus containing food or gastric contents. Persistent sore throat or bad breath due to reflux.

Diagnosis Path: Medical history review focusing on symptoms and risk factors. Physical examination to assess signs of reflux or complications. Endoscopy: allows direct visualization of the esophagus and stomach to identify inflamed tissue or damage. Esophageal pH monitoring: measures acid exposure in the esophagus over 24 hours. Esophageal manometry: assesses the function of esophageal muscles and sphincters. Barium swallow radiography: X-ray imaging to observe the movement of esophageal contents.

Treatment Protocols: Lifestyle modifications: maintaining a healthy weight, avoiding trigger foods, eating smaller meals, and refraining from lying down after eating. Medications: antacids to neutralize acid, H2-receptor blockers and proton pump inhibitors to reduce acid production, and prokinetics to enhance gastric emptying. Surgical options: procedures such as fundoplication may be considered in severe or refractory cases. Endoscopic treatments: emerging minimally invasive options to improve the function of the lower esophageal sphincter. Monitoring and follow-up: regular check-ups to assess response to treatment and adjust as necessary.
