Subglottic stenosis or upper airway scarring is the narrowing and scarring of your upper trachea, which may cause difficulty breathing.

UES dysfunction occurs when the upper esophageal segment (UES) — the muscular segment separating the throat from the esophagus — is either open or too loose, which allows food to back up into the throat from the esophagus, or too tight, which prevents food from moving from the throat to the stomach.

Esophageal dysmotility is when there is a problem with moving food through the esophagus from throat to stomach. The esophagus is the muscular tube leading from the throat to the stomach. Normally, contractions move food from the throat to the stomach through the esophagus.

Diverticulum is a weakness in the wall of the esophagus (food tube leading to the stomach) that results in the development of a pouch that can trap food and cause pain and discomfort when swallowing.

Dysphagia is the term for trouble swallowing. Dysphagia in adults may be caused by tumors, gastroesophageal reflux disease or conditions that cause the throat or esophagus to narrow or weaken.
