Dysphagia is a medical condition characterized by difficulty in swallowing. It can occur at any stage of the swallowing process, from the mouth to the esophagus. Dysphagia is a symptom rather than a disease and can result from various underlying conditions.

Causes

Dysphagia can be caused by a wide range of conditions, which can be broadly categorized into two types: oropharyngeal dysphagia and esophageal dysphagia.

Oropharyngeal Dysphagia

Oropharyngeal dysphagia involves difficulty in initiating the swallowing process. It is often due to neurological disorders such as stroke, Parkinson's disease, or multiple sclerosis. Other causes include muscular disorders like myasthenia gravis and structural abnormalities such as Zenker's diverticulum.

Esophageal Dysphagia

Esophageal dysphagia occurs when there is a problem in the esophagus. Common causes include gastroesophageal reflux disease (GERD), esophageal stricture, and achalasia. Tumors and foreign bodies can also obstruct the esophagus, leading to dysphagia.

Symptoms

The primary symptom of dysphagia is difficulty swallowing. Other symptoms may include:

• Pain while swallowing (odynophagia)
• Regurgitation of food
• Sensation of food being stuck in the throat or chest
• Drooling
• Coughing or choking during eating
• Unexplained weight loss

Diagnosis

The diagnosis of dysphagia typically involves a combination of patient history, physical examination, and diagnostic tests. Common tests include:

• Barium swallow
• Endoscopy
• Esophageal manometry
• Videofluoroscopic swallow study

Treatment

Treatment for dysphagia depends on the underlying cause. Options may include:

• Dietary changes, such as modifying food texture
• Swallowing therapy with a speech-language pathologist
• Medications to reduce acid reflux or relax the esophagus
• Surgical interventions to remove obstructions or repair structural abnormalities

Complications

If left untreated, dysphagia can lead to serious complications, including:

• Malnutrition and dehydration
• Aspiration pneumonia
• Reduced quality of life
