What medical condition has peristaltic contractions as one of its symptoms?

The medical condition that has peristaltic contractions as one of its symptoms is gastroesophageal reflux disease (GERD). GERD occurs when stomach acid flows back into the esophagus. This can cause a burning sensation, pain, and difficulty swallowing. Peristaltic contractions are the wave-like muscle movements that help move food through the digestive tract. In the case of GERD, these contractions can be weak or ineffective, which can lead to stomach acid reflux.
