Acid Reflux in Babies

Acid reflux, also known as gastroesophageal reflux (GER), is a common condition that affects many babies. It occurs when stomach acid flows back up into the esophagus, causing discomfort and other symptoms.

Causes of Acid Reflux in Babies

Acid reflux in babies is often caused by:

  • Immature digestive system: Babies' digestive systems are still developing, which can lead to acid reflux.
  • Weak lower esophageal sphincter (LES): The LES is a muscle that separates the esophagus and stomach. If it's weak, stomach acid can flow back up into the esophagus.
  • Overfeeding or feeding too quickly: This can put pressure on the stomach, causing acid to flow back up into the esophagus.
  • Lying down after feeding: This can cause stomach acid to flow more easily back up into the esophagus.

Symptoms of Acid Reflux in Babies

Common symptoms of acid reflux in babies include:

Diagnosis of Acid Reflux in Babies

A doctor may diagnose acid reflux in babies based on:

  • Physical examination: The doctor will examine the baby's overall health and look for signs of acid reflux.
  • Medical history: The doctor will ask about the baby's feeding habits, vomiting, and other symptoms.
  • Tests: In some cases, the doctor may order tests such as a pH probe or an upper GI series to confirm the diagnosis.

Treatment of Acid Reflux in Babies

Treatment for acid reflux in babies usually involves:

  • Lifestyle changes: Feeding the baby smaller, more frequent meals, burping them regularly, and keeping them upright after feeding can help alleviate symptoms.
  • Medications: In some cases, the doctor may prescribe medications such as antacids or acid reducers to help reduce stomach acid.

Home Remedies for Acid Reflux in Babies

Some home remedies that may help alleviate acid reflux symptoms in babies include:

  • Keeping the baby upright after feeding: This can help prevent stomach acid from flowing back up into the esophagus.
  • Using a wedge pillow: Placing a wedge pillow under the baby's mattress can help keep them at an angle, reducing symptoms of acid reflux.
  • Avoiding overfeeding: Feeding the baby smaller, more frequent meals can help reduce pressure on the stomach and alleviate symptoms.

When to Seek Medical Attention

If a baby is experiencing any of the following symptoms, it's essential to seek medical attention:

  • Vomiting blood or black tarry stools
  • Difficulty breathing
  • Refusal to feed or showing signs of dehydration
