Question

Earliest symptom of gastroesophageal reflux disease (GERD) that becomes pathological in an infant is?

• A. Respiratory distress
• B. Upper GI bleed
• C. Regurgitation and vomiting
• D. Food bolus obstruction

Hint:

Normal infants only spit up; once frequent vomiting starts, reflux has turned pathological.

Answer 1

The Correct Option is C

Reflux of gastric contents is near-universal in young infants, so the clinical challenge is deciding when ordinary spitting up has crossed into disease. The key marker of that transition is the character and persistence of what comes back up. A baby with simple physiological reflux brings up small amounts of milk after feeds without effort, stays comfortable, and gains weight normally. When the same baby starts to vomit and regurgitate frequently, that change is the first clinical flag that the reflux has become GERD rather than a benign developmental phase. We can rule out the alternatives by timing: respiratory distress, when it occurs, follows aspiration or chronic airway irritation and therefore appears late in the course. An upper gastrointestinal bleed reflects established erosive esophagitis, and food bolus obstruction reflects a peptic stricture, both being downstream complications that take time to develop. Because the question specifically asks for the earliest symptom marking pathology, the answer must be the frequent regurgitation and vomiting that first separates GERD from normal infant reflux. $\text{Frequent regurgitation and vomiting} = \text{earliest pathological sign}$.\[\boxed{\text{Regurgitation and vomiting}}\]
