Disorders of the nervous system (e.g. multiple sclerosis, Parkinson’s disease) or immune system can weaken the muscles of the throat and esophagus, preventing proper swallowing. Scleroderma, esophageal spasms, and injuries of the brain or spinal cord can also affect muscle control.
Blockages of the throat or esophagus may occur as a result of gastroesophageal reflux disease (GERD), inflammation of the esophagus, diverticula, hiatal hernias, or tumors.
To determine the cause of your swallowing trouble, your doctor may order a barium swallow study or fluoroscopy. X-rays, laryngoscopy, and other tests can help pinpoint the source of the problem. Treatment will vary depending upon the cause. Medications, surgery, lifestyle changes, and swallowing exercises are all popular treatment methods. Severe cases might require use of a feeding tube.
