Zenker's diverticulum is associated with which of the following symptoms?

Zenker's diverticulum primarily presents with dysphagia, which is difficulty swallowing. This condition involves the formation of a pouch (diverticulum) at the upper esophagus, leading to a disruption in the normal swallowing process. Patients often report that they have difficulty swallowing solid foods or may experience a feeling of a lump in the throat. This can be attributed to the diverticulum itself catching food, which can lead to further complications such as aspiration or regurgitation.

Although chest pain, heartburn, and odynophagia may be associated with various esophageal disorders or conditions affecting the gastrointestinal tract, they are not the hallmark symptoms of Zenker's diverticulum. Instead, dysphagia is the most defining symptom that directly relates to the mechanical obstruction and physiological changes occurring due to the diverticulum formation. Consequently, recognizing dysphagia in the context of this condition is critical for diagnosis and management.
