Medical evaluation is important if reflux symptoms are persistent or if you develop warning signs such as:
* Difficulty or pain when swallowing
* Persistent vomiting
* Unexplained weight loss
* Loss of appetite
* Vomiting blood
* Black or tarry stools
* Ongoing chest pain
These symptoms can indicate complications or a condition other than ordinary reflux.
Chest pain deserves particular caution because heart problems can sometimes resemble severe heartburn.
## Can Untreated GERD Cause Complications?
Yes, although most people do not develop serious complications.
Long-term reflux can sometimes contribute to:
* Esophagitis
* Esophageal ulcers
* Narrowing of the esophagus
* Barrett’s esophagus
This is another reason persistent reflux should not simply be ignored.
