Oral Cavity (Mouth): The process begins here:

• Teeth for chewing
• Tongue for food manipulation
• Salivary glands for lubrication
• Hard and soft palate

Pharynx (Throat): Critical junction area:

• Receives food from mouth
• Routes food to esophagus
• Protects airway during swallowing
• Contains muscles that initiate swallow

Esophagus: The swallowing tube:

• 25 cm muscular tube
• Connects pharynx to stomach
• Peristalsis moves food downward
• Two sphincters control entry/exit

Upper Esophageal Sphincter (UES): Also called cricopharyngeus:

• Prevents air from entering esophagus
• Opens to allow swallow
• Prevents regurgitation

Lower Esophageal Sphincter (LES): At esophagus-stomach junction:

• Prevents acid reflux
• Relaxes to allow food entry
• Dysfunction causes reflux or achalasia

Digestive System: Primary system involved; any part from mouth to stomach can cause symptoms.

Respiratory System: Aspiration risk when swallowing fails; lungs can be affected by repeated aspiration.

Nervous System: Neurological conditions commonly cause dysphagia; cranial nerves control swallowing.

Musculoskeletal: Muscles of mastication, tongue, pharynx, and esophagus involved.

Q: Is difficulty swallowing the same as choking? A: No. Dysphagia is difficulty moving food through the throat/esophagus, while choking is airway blockage.

Q: Can anxiety cause swallowing difficulty? A: Yes, anxiety can cause globus sensation (lump in throat feeling), but persistent symptoms should be evaluated.

Q: Does GERD cause permanent damage? A: Untreated severe GERD can cause complications including strictures and Barrett's esophagus.

Q: Can swallowing problems be cured? A: Many causes are treatable; others can be managed with therapy and modifications.

Q: Are there exercises to help swallowing? A: Yes, speech-language pathologists can provide specific exercises.
