Mechanical Dysphagia

Mechanical dysphagia is a condition that affects a person’s ability to swallow food and liquids due to physical blockages or problems with the structures involved in swallowing. In this article, we will provide simplified explanations for various aspects of mechanical dysphagia, including its types, causes, symptoms, diagnostic tests, treatments, and drugs.

Types of Mechanical Dysphagia:

Mechanical dysphagia can be classified into two main types:

1. Oropharyngeal Dysphagia: Oropharyngeal dysphagia occurs when there are issues with the mouth and throat muscles, making it difficult to initiate swallowing. Common causes include nerve damage, muscle weakness, or neurological disorders.
2. Esophageal Dysphagia: Esophageal dysphagia arises when there are obstructions or problems within the esophagus itself. It can be caused by conditions like strictures, tumors, or inflammation.

Common Causes of Mechanical Dysphagia:

Understanding the underlying causes of mechanical dysphagia is crucial for effective management. Here are 20 common causes in plain language:

1. Achalasia: A condition where the lower esophageal sphincter doesn’t relax properly, causing difficulty in food passage.
2. Esophageal Strictures: Narrowing of the esophagus due to scar tissue formation, often caused by acid reflux.
3. Hiatal Hernia: Part of the stomach pushes up through the diaphragm, causing swallowing difficulties.
4. Esophageal Tumors: Growths in the esophagus, which can block the passage of food.
5. GERD (Gastroesophageal Reflux Disease): Frequent acid reflux can irritate and damage the esophagus, making it hard to swallow.
6. Stroke: Neurological damage from a stroke can affect the muscles used in swallowing.
7. Multiple Sclerosis (MS): MS can disrupt nerve signals that control swallowing.
8. Parkinson’s Disease: This condition can lead to muscle stiffness and difficulty in coordinating swallowing muscles.
9. Cervical Spine Issues: Problems with the neck’s bones or discs can impact the nerves responsible for swallowing.
10. Scleroderma: A rare autoimmune disease that can affect the esophagus and cause stiffness.
11. Radiation Therapy: Radiation treatment for cancer in the chest or neck can damage the esophagus.
12. Esophageal Diverticula: Pouches that form in the esophagus and trap food.
13. Cricopharyngeal Dysfunction: A problem with the upper esophageal sphincter that makes it hard to initiate swallowing.
14. Foreign Bodies: Accidentally swallowing objects can obstruct the esophagus.
15. Esophageal Webs: Thin membranes that can form in the esophagus and obstruct food flow.
16. Schatzki’s Ring: A narrowing at the lower end of the esophagus that can cause difficulty swallowing large pieces of food.
17. Zenker’s Diverticulum: A pouch that forms in the throat, collecting food and causing swallowing difficulties.
18. Systemic Sclerosis: A connective tissue disorder that can affect the esophagus.
19. Medications: Certain medications can cause dry mouth or throat spasms, leading to swallowing problems.
20. Infections: Infections in the throat or esophagus can cause inflammation and make swallowing painful.

Common Diagnostic Tests for Mechanical Dysphagia:

Diagnosing mechanical dysphagia involves various tests to pinpoint the underlying cause. Here are 20 common diagnostic tests explained simply:

1. Barium Swallow Test: A liquid containing barium is swallowed, and X-rays are taken to observe the flow of barium through the esophagus.
2. Endoscopy: A thin tube with a camera is inserted through the mouth to visually examine the esophagus.
3. Manometry: Measures the pressure in the esophagus and how well it moves food.
4. Esophageal pH Monitoring: Monitors acid levels in the esophagus to detect reflux.
5. CT Scan: Cross-sectional images are taken to identify structural issues.
6. MRI: Uses magnetic fields and radio waves to create detailed images.
7. Esophageal Biopsy: A small tissue sample is taken for examination.
8. Video Fluoroscopy: Real-time X-ray images are used to assess swallowing.
9. Upper GI Series: X-rays are taken while the patient swallows barium.
10. Esophageal Manometry: Measures muscle contractions in the esophagus.
11. Electromyography (EMG): Records muscle activity during swallowing.
12. Transnasal Endoscopy: A smaller endoscope is passed through the nose for examination.
13. pH Impedance Testing: Measures acid and non-acid reflux episodes.
14. FEES (Fiberoptic Endoscopic Evaluation of Swallowing): A flexible scope is passed through the nose to evaluate swallowing.
15. Ultrasound: Uses sound waves to create images of the esophagus.
