Acid Reflux (Heartburn); Common Signs & Emergency Symptoms

3. Regurgitation

A feeling of food, bile or liquid moving upward towards your throat instead of moving downward, is known as regurgitation. In a few cases, vomiting may occur in adults. Children and infants having acid reflux disease may have repeated regurgitations. This condition can be completely harmless and quite natural in infants aged less than 18 months. As per the research of National Digestive Diseases Information Clearinghouse, around 50% of the infants have acid reflux during the first three months.

However, it is not entirely harmless in adults due to the maturation of the inner lining of the esophagus. Chronic regurgitation can lead to increased severity of the disease and also increase the risk of lower esophageal cancer.
