			| Definition | A narrowing of the esophagus (the tube from the mouth to the stomach) which causes  swallowing difficulties  . | 
			| Alternative Names |  | 
			| Causes, incidence, and risk factors | Esophageal stricture can be caused by:Gastroesophageal reflux    (GERD), where stomach secretions irritate the esophagus    Prolonged use of a nasogastric tube while under medical care    Ingestion of corrosive substances    Viral or bacterial infections    Treatment of   esophageal varices   Injuries caused by endoscopes (small cameras used during surgery or certain tests) | 
			| Symptoms | Difficulty swallowingPain with swallowingWeight loss   Regurgitation of food | 
			| Signs and tests | A   barium swallow   shows narrowing of the esophagus.    An   endoscopy   shows narrowing of the esophagus. | 
			| Treatment | Dilation (stretching) of the esophagus is the preferred treatment. Repeated dilation may be necessary to prevent the stricture from returning.  Proton pump inhibitors (acid-blocking medicines) can keep a peptic stricture from returning. Surgical treatment is rarely necessary. | 
			| Support Groups |  | 
			| Expectations (prognosis) | The patient may develop the stricture again in the future. | 
			| Complications | Swallowing difficulties   may keep the patient from getting enough fluids and nutrients. There is also an increased risk (with regurgitation) of having food, fluid, or vomit enter the lungs and cause choking or  aspiration pneumonia  . | 
			| Calling your health care provider | Call your health care provider if  swallowing difficulty   persists. | 
			| Prevention | Prevention is related to the causes. For example, use safety measures to avoid ingestion of corrosive substances. (Keep dangerous products out of the reach of children). Persistent reflux disease should be evaluated by a physician. |
