Which of the following are potential complications of chronic regurgitation?

• A. Dehydration and electrolyte disturbances only.
• B. Weight gain and improved appetite.
• C. Aspiration pneumonia, malnutrition, dehydration, electrolyte disturbances, weight loss.
• D. No complications occur.

Answer: (C)

Chronic regurgitation can affect multiple body systems because repeated backflow of stomach contents can be aspirated into the lungs and also leads to ongoing loss of fluids and nutrients. The most important complication is aspiration pneumonia, which occurs when regurgitated material enters the airways and causes infection. At the same time, persistent regurgitation often results in malnutrition and weight loss due to inadequate intake and loss of nutrients, while the repeated loss of fluids in regurgitated material can cause dehydration and electrolyte disturbances. Together these problems reflect the broad impact regurgitation can have on nutrition, fluids, and respiratory health. Options that mention only dehydration or electrolytes miss the nutritional and respiratory risks, while suggesting weight gain or no complications contradicts the expected effects of chronic regurgitation.
