Dysphagia is difficulty swallowing — Dysphagia indicates a delay in the passage of solids or liquids from the mouth to the stomach.
Dysphagia should be distinguished from odynophagia which is discomfort or pain on swallowing hot or cold liquids, and occasionally alcohol. In some cases, swallowing is impossible.
Occasional difficulty swallowing, such as when you eat too fast or don't chew your food well enough, usually isn't cause for concern. But persistent dysphagia can be a serious medical condition requiring treatment.
