T17.31

Clinical Causes: Gastroesophageal reflux disease (GERD), where stomach acid frequently flows back into the esophagus and may reach the larynx Dysphagia, or difficulty swallowing, that increases the risk of food or liquids entering the airway Impaired or delayed swallowing reflex, often seen in neurological conditions such as stroke or Parkinson's disease Sleep-related disorders such as sleep apnea, which can increase the likelihood of aspiration during sleep Procedural or surgical interventions involving the upper digestive or respiratory tracts that may disturb normal protective mechanisms Chronic coughing or excessive vomiting that can lead to accidental inhalation of gastric contents

Key Symptoms: Persistent cough, especially after eating or lying down Sensation of a lump or something stuck in the throat Hoarseness or voice changes Difficulty breathing or shortness of breath Throat irritation or sore throat Episodes of choking or coughing during meals In some cases, signs of aspiration pneumonia, including fever, chest discomfort, or increased respiratory rate

Diagnosis Path: Flexible laryngoscopy to visualize the larynx and identify aspirated material Barium swallow studies to assess swallowing mechanics and identify reflux pH monitoring to detect acid reflux episodes Imaging studies like chest X-ray if aspiration pneumonia or other lung issues are suspected Esophageal manometry to evaluate swallow function and esophageal motility

Treatment Protocols: Lifestyle modifications such as elevating the head of the bed, avoiding late meals, and dietary changes to reduce reflux Medications like proton pump inhibitors (PPIs) or H2 receptor blockers to decrease stomach acid production Speech and swallowing therapy to improve swallowing safety and reduce aspiration risk Surgical interventions in severe cases, such as fundoplication, to reinforce the lower esophageal sphincter Managing underlying neurological or structural conditions that contribute to impaired swallowing
