When you swallow, you are chewing food and moving it to the esophagus, a tube that connects to the stomach. Dysphagia, the medical term for difficulty swallowing, is characterized by the sensation of food or liquid getting stuck in the throat or chest. There are numerous factors that can cause swallowing difficulty, most of them fairly benign.
Symptoms & Causes
Swallowing disorders indicate persistent problems with chewing and swallowing. The main symptoms are discomfort when swallowing, chest pain, and the feeling that food or liquid is getting stuck in the throat or chest. Additionally, you may experience drooling, heartburn, nausea, wheezing, coughing, regurgitation, sore throat, and a sour taste in the mouth.
Causes of dysphagia are diverse. They may originate in the esophagus and include diffuse spasm, an improperly relaxed sphincter, weak esophageal muscles, a narrow esophagus or esophageal ring, the presence of foreign bodies, gastroesophageal reflux disease (GERD), a hardening of the tissues called scleroderma, and tumors. In addition, the muscles and nerves responsible for swallowing can weaken as a result of neurological disorders, pharyngeal diverticula or cancer. Children may have difficulty swallowing if they suffer from certain nervous system disorders or a cleft palate.
