Symptoms are only occasional and do not occur everyday. They include:

- Food getting stuck in the throat
- Spooning of nails or sunken nails

- Esophageal dilation to widen the narrow part of esophagus
- Electrocautery to reduce the size of the ring through electric current
There is no way to prevent esophageal rings or webs.
