Gastroesophageal Reflux Disease (GERD)
GERD, or gastroesophageal reflux disease, is a condition in which the stomach contents are refluxed back into the esophagus. The acidic stomach contents can damage the delicate tissues in the mouth, leading to painful canker sores. Gastroesophageal Reflux Disease can also cause heartburn and other symptoms. In addition, people with GERD are at an increased risk of developing canker sores and other mouth problems, such as dry mouth and cracked lips.
The exact cause of canker sores is unknown, but they are thought to be related to an underlying problem with the immune system. People with GERD may be more likely to develop canker sores due to the irritation caused by stomach acids backing up into the esophagus.
Treatment for canker sores usually relieves pain and protects the sore from further irritation. In some cases, medications may be prescribed to reduce stomach acid production. Making lifestyle changes such as quitting smoking and losing weight may also help. Your doctor may refer you to a specialist for additional treatment for severe or recurring canker sores.
