About one in 25 adults develops a swallowing problem every year. About 3-9% of the general population seek treatment for a voice disorder, but the experts believe many more people develop voice changes yet don’t get medical care.
What are Voice and Throat Disorders?
Throat disorders primarily include two types of problems, voice disorders and swallowing disorders:
- Voice Disorders: Your vocal cords are two folds of tissue in your larynx (voice box). When you breathe, your vocal cords stay open; when you speak or sing, they come together. As air flows over the closed vocal cords, they vibrate to produce sound. The quality of your voice changes when a problem affects the way your vocal cords vibrate. When that happens, you have a voice disorder.
- Swallowing Disorders: Difficulty swallowing, which is called dysphagia, occurs when it’s hard to move food or liquid from your mouth into your stomach. Proper swallowing involves multiple steps, such as:
- Thoroughly chewing your food
- Using your tongue to move food to the back of your mouth
- Muscles open at the back of your throat, so food goes into the esophagus
- Muscle contractions propel food down your esophagus
- Muscles open at the bottom of your esophagus to let food into your stomach
Problems can occur at any step of the process, which can make it hard to swallow.
