Reflux is a common digestive disorder that occurs when the contents of the stomach are regurgitated back up into the esophagus, resulting in uncomfortable symptoms such as heartburn, nausea, and chest pain. The severity of reflux symptoms can vary significantly from person to person, but there is often an age at which reflux is the worst.
Generally, reflux is most severe in infants and young children, usually between the ages of two and four. During this period, the lower esophageal sphincter (LES) is immature and not as effective at preventing the reflux of stomach contents into the esophagus. As a result, infants and young children are particularly vulnerable to reflux and suffer from more frequent and severe episodes. In addition, infants and young children may not be able to verbalize the discomfort they are experiencing, making it even more difficult to diagnose and treat.
In older children and adults, reflux can be just as uncomfortable, but is usually more manageable. As people age, the LES matures and becomes more effective at keeping stomach contents where they belong. However, certain lifestyle risk factors such as diet, obesity, and smoking can contribute to worsening reflux symptoms in older children and adults.
Overall, reflux is often worst during infancy and early childhood, but can still be a problem for older children and adults. Reflux can be managed with lifestyle modifications, diet changes, and medications, and it is important to talk to your doctor if you or your child are experiencing persistent or severe reflux symptoms.
