The mouth and esophagus move food from the lips to the stomach. Disorders here threaten three things at once: airway protection, nutrition, and comfort. Swallowing problems raise the risk of aspiration and weight loss, so every client with an oral or esophageal disorder needs a swallowing and nutrition plan.

Oral disorders

Esophageal disorders

Mechanical obstruction (cancer, stricture) typically causes dysphagia to solids first. Motility disorders such as achalasia cause dysphagia to solids and liquids together.

Subjective

• Heartburn, regurgitation, sour taste, chronic cough or hoarseness (reflux), chest pain
• Dysphagia (where food sticks, solids vs liquids, progression), odynophagia (painful swallowing)
• Weight loss, anorexia, mouth pain, altered taste, dry mouth
• Tobacco, alcohol, betel chewing, hot-beverage habits; medications (NSAIDs, bisphosphonates, potassium tablets, doxycycline can injure the esophagus)

Objective

• Oral inspection with good light: color, lesions, white or red patches (leukoplakia, erythroplakia), ulcers lasting more than 2 weeks, loose teeth, denture fit
• Signs of aspiration: coughing or choking with meals, wet voice, fever, crackles
• Nutrition: weight trend, oral intake, hydration status
• Neck lymph nodes (oral and esophageal cancer)

Chest pain: rule out acute coronary syndrome first (ECG, troponin) before attributing chest pain to GERD or esophageal spasm.

Alarm features that need prompt endoscopy: dysphagia, odynophagia, weight loss, GI bleeding, anemia, persistent vomiting.

Nursing care for EGD: NPO before the procedure as ordered; after the procedure, monitor airway, SpO₂, and level of consciousness after procedural sedation; keep NPO until the gag reflex returns; monitor for sore throat (expected) versus perforation signs.

GERD

• Lifestyle changes first (see Client Education)
• Proton pump inhibitors (PPIs) — omeprazole, esomeprazole, pantoprazole: most effective acid suppressants. Take 30–60 minutes before the first meal of the day. Long-term risks: vitamin B12 deficiency, hypomagnesemia, fractures, Clostridioides difficile infection. Omeprazole and esomeprazole reduce activation of clopidogrel; pantoprazole is preferred when a PPI is needed with clopidogrel. Use the lowest effective dose and reassess the need regularly
• H2-receptor antagonists — famotidine: reduce dose in kidney impairment; confusion possible in older adults
• Antacids — for occasional symptoms: aluminum products constipate, magnesium products cause diarrhea; both magnesium and aluminum accumulate and are avoided or used cautiously in kidney failure; long-term aluminum use can cause hypophosphatemia; separate from other oral drugs by about 1–2 hours because they bind many drugs
• Metoclopramide (prokinetic) — boxed warning for tardive dyskinesia; avoid use longer than 12 weeks; contraindicated in GI obstruction, perforation, or bleeding and in seizure disorders
• Surgery: laparoscopic fundoplication for selected clients; post-op temporary dysphagia and inability to belch or vomit ("gas-bloat")

Barrett esophagus: long-term PPI and endoscopic surveillance; endoscopic ablation for dysplasia.

Achalasia: pneumatic dilation, laparoscopic Heller myotomy, or peroral endoscopic myotomy (POEM); botulinum toxin injection for poor surgical candidates. Dilation carries a risk of esophageal perforation.

Esophageal cancer: esophagectomy with gastric pull-up (the stomach is brought into the chest), chemoradiation, stenting or dilation for palliation of dysphagia.

Oral cancer: surgical excision (e.g., partial glossectomy, mandibulectomy, neck dissection) with reconstruction, radiation, chemotherapy. A dental evaluation before head and neck radiation reduces the risk of osteoradionecrosis.

Mucositis and xerostomia

• Bland rinses (saline or sodium bicarbonate), topical anesthetics before meals, systemic analgesics for severe pain
• Candidiasis: nystatin suspension (remove and disinfect dentures; swish for at least 1–2 minutes, then swallow) or fluconazole (QT prolongation and many drug interactions)
• Pilocarpine for radiation-induced dry mouth: causes sweating; avoid in uncontrolled asthma and narrow-angle glaucoma

Esophageal variceal ligation (band ligation): endoscopic banding stops bleeding and prevents rebleeding (full management in Liver Disorders).

Listed in priority order.

1. Airway and aspiration prevention
   • After oral or neck surgery: head of bed elevated, suction at bedside, monitor for stridor, swelling, and bleeding; tracheostomy care if present
   • Swallow screening before any oral intake; upright 90° for meals, small bites, thickened liquids if ordered
   • After EGD or dilation: nothing by mouth until the gag reflex returns
2. Detect perforation and bleeding early
   • After dilation or endoscopy: chest, neck, or back pain, fever, tachycardia, subcutaneous emphysema, dyspnea suggest esophageal perforation — notify the provider immediately and keep NPO
   • After variceal banding: monitor for hematemesis, melena, tachycardia, and hypotension; keep blood pressure stable and avoid straining, forceful coughing, and vomiting, which raise pressure in the varices; mild chest discomfort and dysphagia for a few days are common
3. Post-esophagectomy care
   • Semi-Fowler's to upright at all times (at least 30°) to prevent reflux and aspiration
   • Do not reposition or irrigate the nasogastric tube without an order — it lies near the anastomosis
   • Watch for anastomotic leak: fever, tachycardia, chest pain, new drainage or air on chest tube, sepsis
   • Pulmonary care: incentive spirometry, early ambulation, pain control
4. Nutrition
   • After extensive glossectomy: enteral feeding by nasogastric or gastrostomy tube until swallowing is safe; speech-language pathology referral
   • Small, frequent, high-calorie, high-protein meals; weigh regularly
5. Oral comfort and integrity
   • Soft toothbrush, frequent bland rinses; avoid alcohol-based mouthwash, hot, spicy, acidic, and rough foods
   • For dry mouth: frequent sips of water, sugar-free gum or lozenges, saliva substitutes, humidifier, fluoride
6. Communication and body image — writing board or device after glossectomy or laryngeal involvement; support for disfigurement

GERD

• Avoid lying down for 2–3 hours after eating; avoid late-night meals
• Raise the head of the bed about 15–20 cm (6–8 in) with blocks or a wedge (extra pillows alone bend the waist and can worsen reflux)
• Lose weight if overweight; stop smoking; limit alcohol
• Identify personal triggers (fatty meals, chocolate, caffeine, peppermint, carbonated drinks, spicy or acidic foods); avoid tight clothing and bending after meals
• Pills that can injure the esophagus (NSAIDs, bisphosphonates, potassium, doxycycline): take upright with a full glass of water and stay upright for at least 30 minutes (30–60 minutes for bisphosphonates, per product)
• Take the PPI before breakfast; do not stop long-term therapy suddenly without guidance (rebound acid)

After esophagectomy

• Eat small, frequent meals; stay upright for at least 1–2 hours after eating; sleep with the head elevated
• Report difficulty swallowing (stricture), weight loss, or symptoms of dumping (dizziness, sweating, diarrhea after meals)

Oral cancer prevention and self-examination

• Monthly self-examination in good light with a mirror: lips, gums, cheeks, tongue (top, sides, underneath), floor of the mouth, palate
• Hold the tongue with clean gauze to pull it to each side; use the fingers to feel the cheeks, floor of mouth, and neck for lumps
• Report sores that do not heal within 2 weeks, white or red patches, lumps, bleeding, numbness, or persistent hoarseness
• Avoid tobacco, betel quid, and excess alcohol; HPV vaccination reduces risk of HPV-related cancers
• Regular dental checkups

During head and neck radiation — rigorous oral hygiene, fluoride trays or gel if prescribed, lifelong dental follow-up.

• Most common acute oral complication of head and neck radiation: mucositis (stomatitis)
• PPIs: take 30–60 minutes before breakfast; long-term risks include B12 deficiency, low magnesium, fractures, C. difficile
• GERD: no lying down 2–3 hours after meals; elevate head of bed; weight loss, stop smoking
• Achalasia: solids and liquids dysphagia, bird's beak on barium swallow
• Esophageal cancer: progressive dysphagia (solids → liquids) and weight loss; Barrett esophagus → adenocarcinoma
• After dilation: chest pain and fever = suspect perforation
• After esophagectomy: stay upright, do not move the NG tube, watch for anastomotic leak
• Mouth care for mucositis/xerostomia: no alcohol-based mouthwash; bland rinses; soft brush
• After glossectomy: protect the airway; feed by tube until swallowing is safe
• After variceal banding: prevent rebleeding — stable blood pressure, avoid straining and vomiting
