Gastroesophageal reflux in infants

Definition

Gastroesophageal reflux is a condition in which stomach contents travels backward from the stomach to the esophagus, rather than down through the digestive system. This article discusses reflux in infants.

Alternative Names

Reflux - infants

Causes

In infants, a small amount of gastroesophageal reflux is normal. Persistent reflux with frequent vomiting leads to irritation of the esophagus. Reflux associated with weight loss or reflux that causes breathing difficulty is considered abnormal.

Symptoms

• Chronic cough
• Excessive crying as if in pain
• Excessive vomiting during the first few weeks of life
• Extremely forceful vomiting
• No breathing or breath-holding spells
• Slow growth
• Weight loss
• Wheezing

Exams and Tests

The baby may have a history of breathing in foods or fluids into the lungs, leading to aspiration pneumonia.

Tests that may be done include:

• Esophageal pH monitoring to determine how often and for how long stomach acid enters the esophagus
• X-ray of the esophagus

Treatment

If your baby has reflux problems, hold him or her upright for 1 to 2 hours after feeding.

When the infant begins to eat solid food, thickened foods are preferable to thin foods.

Sometimes medicines are used to help reduce symptoms, such as antacids or a prescription drug called metoclopramide (Reglan).

Outlook (Prognosis)

The majority of infants outgrow this condition. In unusual cases, reflux may persist into childhood and can cause varying degrees of esophageal damage.

Possible Complications

• Aspiration pneumonia caused by stomach contents passing into the lungs
• Irritation and swelling of the esophagus
• Scarring and narrowing of the esophagus

When to Contact a Medical Professional

Call your health care provider if your baby is vomiting frequently, especially if the vomiting is forceful or if other symptoms of reflux occur.

Prevention

Hold your baby upright for some time after meals. Hold your baby upright for some time after meals.
