GERD stands for gastroesophageal reflux disease. You may also hear it called acid indigestion or heartburn. It happens when stomach contents flow back up (reflux) into the esophagus. The esophagus is the tube that connects the mouth to the stomach. This can irritate the esophagus. It can also cause problems with swallowing or breathing. In severe cases, GERD can cause pneumonia that keeps coming back or other serious problems.
A baby may have reflux if you see any of the following soon after eating:
- Spitting up
- Vomiting
- Frequent hiccups
- Coughing spells
- Unusual fussiness or irritability
Most babies show signs of some reflux during the first few weeks of life. This condition is often harmless. By 7 months, the valve in the esophagus should be more developed, and symptoms should ease. By the time a baby has been walking for 3 months, reflux normally has gone away.
Symptoms of GERD in older children include:
- Food or liquid coming up in the back of the mouth (spitting up)
- Feeling of burning in the chest (heartburn) or stomach pain
- Belching
- Bad breath
- Acid or bitter taste in the mouth
- Cough that continues, especially at night or on waking
