What is a common fallacy about nutrition and hydration in terminally ill patients, and what evidence counters it?

• A. A common fallacy is dehydration is thought to be an uncomfortable state; at the end of life, patients rarely complain of thirst, and aggressive artificial nutrition and hydration can be more harmful and can produce life-threatening symptoms.
• B. A common fallacy is dehydration is harmless; evidence shows thirst is rare.
• C. Dehydration leads to increased endorphin levels; evidence shows endorphins decrease.
• D. Dehydration has no effect on comfort; evidence shows dehydration worsens discomfort.

Answer: (A)

Dehydration at the end of life is often approached with the assumption that it’s an uncomfortable, tolerated state and that patients won’t report thirst, leading to withholding fluids. But evidence shows thirst and dry mouth can be distressing for many terminally ill patients, and withholding hydration can worsen discomfort in some cases. At the same time, aggressive artificial nutrition and hydration can bring harmful effects—pulmonary congestion from fluid overload, increased secretions that irritate the airway, edema, nausea, vomiting, or risk of aspiration—without reliably improving comfort or prognosis. The best approach is to focus on comfort and symptoms, offering hydration carefully and only to relieve thirst if it improves the patient’s comfort, while avoiding large volumes or invasive measures that could cause harm.
