What is difficulty swallowing (dysphagia)?
Difficulty swallowing is also called dysphagia. It is usually a sign of a problem with your throat or esophagus—the muscular tube that moves food and liquids from the back of your mouth to your stomach. Although dysphagia can happen to anyone, it is most common in older adults, babies, and people who have problems of the brain or nervous system.
There are many different problems that can prevent the throat or esophagus from working properly. Some of these are minor, and others are more serious. If you have a hard time swallowing once or twice, you probably do not have a medical problem.

He or she may also check your reflexes, muscle strength, and speech. Your doctor may then refer you to one of the following specialists:
To help find the cause of your dysphagia, you may need one or more tests, including:
How is it treated?
Your treatment will depend on what is causing your dysphagia. Treatment for dysphagia includes:
In rare cases, a person who has severe dysphagia may need a feeding tube because he or she is not able to get enough food and liquids.
