Choking phobia: a review of the literature.

Choking phobia is characterized by fear and avoidance of swallowing food, fluids, or pills. Most individuals with this phobia suddenly acquire their fear after an episode of choking on food. Fear of choking appears to occur somewhat more often in females than in males, and has a variable age of onset ranging from childhood to old age. Its prevalence is unknown. Choking phobia appears responsive to antipanic medication and to certain cognitive and behavioral therapies.
