Difficulty swallowing (dysphagia) means it takes more time and effort to move food or liquid from your mouth to your stomach. Dysphagia may also be associated with pain. In some cases, swallowing may be impossible.
Occasional difficulty swallowing, which may occur when you eat too fast or don't chew your food well enough, usually isn't cause for concern. But persistent dysphagia may indicate a serious medical condition requiring treatment.
Dysphagia can occur at any age, but it's more common in older adults. The causes of swallowing problems vary, and treatment depends on the cause.
