Not every regurgitation is disease. Not every child needs a pill.
At the 20th Brazilian Congress of Pediatric Gastroenterology and Hepatology, clinicians gathered around a question as old as parenthood itself: when does a child's discomfort cross the threshold from the ordinary into the pathological. Dr. Adriana Aguiar offered a framework for distinguishing physiological reflux—a normal feature of infant life—from true GERD, a condition defined not by the presence of reflux but by its consequences on a child's wellbeing. Her guidance reflects a broader wisdom in medicine: that restraint, careful listening, and graduated response often serve patients better than the reflexive reach for intervention.
- Parents and clinicians alike struggle to tell apart harmless infant spit-up from a condition that genuinely threatens a child's growth and comfort—and the stakes of getting it wrong run in both directions.
- Because GERD symptoms shift dramatically with age—from vague irritability in infants to reported heartburn in teenagers—no single diagnostic test can reliably confirm the disease across all presentations.
- Certain children face meaningfully higher risk: those born prematurely, those with neurological or genetic conditions, lung disease, or structural anomalies of the esophagus demand closer scrutiny rather than simple reassurance.
- The recommended path forward begins with the least invasive steps—adjusting feeding frequency, thickening formula, eliminating cow's milk protein, managing weight—before any medication enters the picture.
- Proton pump inhibitors, widely used in adult gastroenterology, are positioned as a last resort for children, reserved only for cases where conservative measures have genuinely failed.
On June 4th, at the 20th Brazilian Congress of Pediatric Gastroenterology and Hepatology, Dr. Adriana Aguiar addressed one of the most common sources of parental anxiety in early childhood: the spitting-up infant. Her central task was drawing a clear line between physiological reflux—a normal, harmless backward flow of stomach contents that occurs many times daily in healthy infants—and gastroesophageal reflux disease, which is defined not by reflux itself but by its consequences: poor weight gain, feeding refusal, or distress significant enough to affect a child's quality of life.
The diagnostic challenge, Aguiar explained, is that GERD in children is a clinical judgment with no gold-standard test to confirm it across all ages. Symptoms evolve with development: infants present with irritability and feeding difficulties, while older children and adolescents describe heartburn and chest pain. This shifting picture means a three-month-old's post-feeding spit-up is almost always normal—but knowing when to move from reassurance to investigation requires recognizing specific red flags, including weight loss, severe irritability, and difficulty swallowing. Children at elevated risk—those born prematurely, or living with neurological conditions, lung disease, genetic syndromes, or structural esophageal anomalies—warrant closer attention.
Treatment, Aguiar emphasized, follows a deliberate hierarchy. For infants, the first interventions are behavioral: adjusting feeding volumes and frequency, considering thickened formula, and trialing a cow's milk protein elimination if allergy may be mimicking reflux. For older children, weight management, dietary modifications, and postural guidance after meals form the foundation. Medication—specifically proton pump inhibitors—enters only when these measures fail. The congress's message was one of calibrated restraint: not every regurgitation signals disease, not every child needs pharmacological treatment, and medicine serves children best when its response is proportionate to the actual severity of the problem.
On June 4th, during the 20th Brazilian Congress of Pediatric Gastroenterology and Hepatology, Dr. Adriana Aguiar took the stage to untangle one of pediatrics' most common diagnostic puzzles: when a baby's spit-up is just a baby being a baby, and when it becomes a disease that needs treating.
The distinction matters because parents worry, and doctors need to know whether to reassure or investigate. Physiological reflux—the simple backward flow of stomach contents—happens many times a day in infants and is entirely normal. It causes no harm. Disease, by contrast, occurs when that same reflux produces symptoms severe enough to damage a child's quality of life: poor weight gain, feeding refusal, or genuine distress. The problem is that telling them apart isn't always straightforward, especially in the first years of life when a baby cannot say what hurts.
Aguiar emphasized that diagnosing gastroesophageal reflux disease, or GERD, in children is fundamentally a clinical judgment call. There is no single test—no gold standard—that works across all ages and presentations. Symptoms shift with development. Infants show vague signs: irritability, crying, refusing to eat. Older children and teenagers report heartburn, chest pain, and stomach discomfort. This age-dependent variation is precisely what makes diagnosis challenging. A parent sees their three-month-old spit up after feeding and fears something is wrong. Most of the time, nothing is.
When should a doctor move beyond reassurance to actual investigation? Aguiar outlined red flags that warrant closer attention: weight loss, difficulty swallowing, severe irritability, persistent feeding refusal. Certain children carry higher risk for worse outcomes: those born prematurely, those with neurological conditions, lung disease, genetic syndromes, or a history of esophageal atresia, hiatal hernia, or diaphragmatic hernia. Obesity and chemotherapy exposure also increase risk. These are the patients who need more than watchful waiting.
The treatment approach Aguiar described follows a clear hierarchy, with medication at the bottom rung. For infants, the first moves are behavioral: avoid overfeeding, adjust how often and how much the baby eats, consider thickened formula. If symptoms persist, a two-to-four-week trial eliminating cow's milk protein sometimes helps, since allergy can mimic reflux disease. For older children and adolescents, weight management, reducing fatty and large meals, and postural adjustments—like not lying flat immediately after eating—form the foundation. Only when these measures fail should doctors reach for proton pump inhibitors, the powerful acid-suppressing drugs that have become reflexive in adult medicine but should be reserved in children for cases that genuinely need them.
What emerged from the discussion was a call for restraint and precision. Not every regurgitation is disease. Not every child needs a pill. The art lies in listening carefully to what the symptoms are telling you, knowing which children are at risk, and starting with the simplest interventions first. Medicine works best when it matches the problem's actual severity.

The diagnosis of GERD is essentially clinical and can be challenging, since symptoms vary by age and there is no diagnostic method considered gold-standard for all presentations— Dr. Adriana Aguiar
La Conversación del Hearth Otra perspectiva de la historia
Why does it matter so much to separate normal reflux from actual disease in babies? Isn't it safer to treat everything?
No, because most infants who spit up are fine, and treating them exposes them to medication risks and costs without benefit. The real skill is knowing which ones actually suffer.
How do you tell the difference if a baby can't talk?
You watch for the things that matter: Are they gaining weight? Do they seem in pain? Are they refusing to eat? Normal reflux doesn't stop a baby from thriving.
What about the parents who are terrified?
That's real, and it's why the conversation matters. A doctor who explains what's normal and what's not, and who has a clear plan if things change, gives parents something better than a prescription—they give them confidence.
So the drugs come later?
Only if the simpler things don't work. Thickened formula, smaller meals, positioning—these work for most babies. The acid blockers are for the ones who still struggle after that.
And older kids are different?
Completely. They can tell you their chest hurts. They have different symptoms. The approach shifts from watching and waiting to active management, but still starting without pills.
