Dysphagia: A Common Reason for Tube Feeding

3 min read

According to medical resources, dysphagia, or difficulty swallowing, is one of the most common reasons for tube feeding. This can be caused by various medical conditions, leading to an inability to safely consume enough nutrients orally and necessitating enteral nutrition to prevent malnutrition and dehydration.

Quick Summary

Enteral nutrition via a feeding tube is often necessary for patients with dysphagia, neurological conditions like stroke, and severe malnutrition to ensure adequate nutrient intake and prevent aspiration.

Key Points

Dysphagia: Difficulty swallowing, often caused by stroke, neurological disorders, or head/neck cancers, is the most common reason for tube feeding due to the risk of aspiration.
Diverse Indications: Beyond swallowing problems, tube feeding is used for severe malnutrition, critical illness (trauma, burns), unconsciousness, and certain gastrointestinal issues.
Tube Types: The duration of nutritional support determines the tube type. Short-term needs use nasogastric (NG) tubes, while long-term needs require surgically placed gastrostomy (G-tube) or jejunostomy (J-tube) tubes.
Benefits of Enteral Nutrition: When the gut is functional, tube feeding is preferred over intravenous nutrition because it costs less, has a lower infection risk, and preserves gut health.
Potential Complications: Risks associated with tube feeding include aspiration pneumonia, tube blockages, infections at the site, and gastrointestinal side effects like diarrhea or constipation.
Team-Based Decision: The decision for tube feeding is a collaborative effort between the patient, family, and a healthcare team, focusing on the patient's individual nutritional needs and overall well-being.

Dysphagia, or difficulty swallowing, is a major reason for needing a feeding tube. Swallowing is complex, involving many muscles and nerves. When it's impaired, there's a risk of aspiration, where food or liquid enters the lungs, potentially causing pneumonia. Tube feeding delivers nutrients directly to the stomach or small intestine, ensuring adequate nutrition and hydration. The decision to use a tube is made carefully, balancing benefits and risks.

Medical Conditions Requiring Tube Feeding

Various medical conditions necessitate tube feeding when a patient cannot eat or cannot eat enough.

Neurological and Muscular Disorders

Conditions affecting nerves and muscles often impair swallowing.

Stroke: A frequent cause of dysphagia.
Motor Neurone Disease (ALS): Causes progressive swallowing muscle weakness.
Parkinson's Disease: Can affect swallowing muscles.
Dementia: May require tube feeding in advanced stages if oral intake is severely compromised.

Critical Illness and Trauma

Severe illness or injury increases nutritional needs while preventing oral intake.

Severe Burns or Trauma: Leads to increased metabolic needs unmeet by oral intake.
Mechanical Ventilation: Prevents eating by mouth.
Unconsciousness or Coma: Patients cannot eat safely.

Gastrointestinal (GI) and Digestive Issues

Problems can occur in the digestive tract beyond swallowing.

Obstruction: Blockages in the throat or esophagus prevent food passage.
Malabsorption: Conditions like Crohn's or celiac disease hinder nutrient absorption.
Surgical Recovery: Temporary tube feeding may be needed after head, neck, or GI surgery.

Other Factors

Failure to Thrive (FTT): Used in children unable to take enough oral nutrition.
Prolonged Anorexia: Can cause severe malnutrition in chronic illness or eating disorders.

Types of Feeding Tubes and Their Placement

The tube type depends on the patient's condition, expected duration, and stomach function.

Comparison of Common Feeding Tube Types


Type of Tube	Insertion Method	Duration of Use	Typical Patient Profile
Nasogastric (NG)	Through the nose into the stomach.	Short-term (less than 4–6 weeks).	Temporary swallowing issues or inability to eat for a limited time.
Gastrostomy (G-tube / PEG)	Surgically placed into the stomach.	Long-term (more than 4–6 weeks).	Neurological disorders, chronic swallowing difficulties.
Jejunostomy (J-tube)	Surgically placed into the small intestine.	Long-term.	Patients with impaired stomach motility or high aspiration risk.
Gastro-Jejunal (GJ-tube)	Tube with ports in stomach and jejunum.	Long-term.	Allows stomach drainage and jejunal feeding.

Potential Complications and Patient Considerations

Tube feeding has potential issues requiring careful management.

Common complications include:

Aspiration Pneumonia: Risk of formula entering lungs, especially with NG tubes. Keep head elevated.
Tube-Related Problems: Blockages, dislodgement, or leakage.
Gastrointestinal Distress: Diarrhea, constipation, nausea.
Refeeding Syndrome: Metabolic issue in severely malnourished patients if feeding starts too fast.
Infection: Requires proper hygiene and site care.

Living with a feeding tube requires adjustment. Support organizations like The Oley Foundation offer resources.

Benefits of Tube Feeding vs. Intravenous Feeding

Enteral nutrition is preferred over intravenous when the GI tract works.

Key benefits of enteral nutrition:

Preserves Gut Integrity: Maintains digestive tract health.
Lower Infection Risk: Less risk than IV nutrition delivered to the bloodstream.
Reduced Cost: Less expensive than IV nutrition.

The Decision for Nutritional Support

The decision involves the patient, family, and healthcare team, including doctors, dietitians, and speech pathologists. They assess nutritional status, swallowing ability, and the underlying condition to create a plan that supports healing and improves quality of life. Tube feeding can be temporary or long-term.

Conclusion

Dysphagia is a common reason for tube feeding, particularly after stroke or with progressive neurological disease. Tube feeding provides safe, effective nutrition when oral intake is compromised. Understanding the reasons, types, complications, and support resources is crucial for informed care.

Frequently Asked Questions

Early signs can include noticeable weight loss, persistent coughing or choking during meals, and a physician's assessment revealing a high risk of aspiration during swallowing.

The decision is based on a comprehensive evaluation by a healthcare team. They assess the patient's ability to swallow, their nutritional status, and the underlying medical condition that is preventing adequate oral intake.

Yes, in many cases, a patient can continue to eat and drink small amounts by mouth, if it's deemed safe. The feeding tube serves to supplement their oral intake and ensure they receive sufficient nutrients.

The duration varies. For short-term issues like recovering from surgery, a tube may only be needed for a few weeks. For chronic conditions like advanced neurological disorders, it may be a long-term solution.

An NG tube is a temporary, non-surgical tube inserted through the nose into the stomach, while a G-tube is surgically placed directly into the stomach through the abdominal wall for longer-term use.

Proper care involves cleaning the site daily with soap and water, keeping it dry, and checking for signs of infection such as redness, swelling, or unusual discharge.

First, try to flush the tube gently with warm water using a syringe. If that doesn't work, contact a healthcare provider immediately. Never attempt to unclog the tube with a wire or other objects.
