Nutritional Supplements for Dysphagia:

Dysphagia occurs when there is a problem with the neural control or the structures involved in any part of the swallowing process. People with dysphagia have difficulty swallowing and may even experience pain while swallowing (odynophagia). 

Often seen with infants and older adults, people who cannot swallow thin liquids may need to add special thickeners to their drinks in order to keep fully nourished.
