How does dysphagia occur?
A. Dysphagia occurs when there is a problem during any part of the swallowing process, a complex procedure that includes 50 pairs of muscles and numerous nerves working to move food from the mouth to the stomach. If we were to analyze the swallowing process, we’d recognize three distinct stages. First, the tongue moves food around in the mouth for chewing, which makes the food the right size to swallow, and helps mix the food with saliva.
