Dysphagia is a swallowing disorder. It is caused by mechanical obstructions in the upper part of the digestive tract (pharynx, esophagus ), damage to its walls, violation of innervation or a combination of these causes. Dysphagia occurs in inflammatory and tumor processes in the tongue, throat, esophagus or in the surrounding tissues and lymph nodes, as well as when the walls of the upper part of the digestive tract are ulcerated. Less often, dysphagia develops in the trigeminal neuralgia, lingual-pharyngeal, overturned nerves and functional spasm of the musculature. Dysphagia can be observed in vascular, infectious and tumor processes in the brain. Treatment is the elimination of the cause that caused dysphagia.
