An intense, persistent fear of a specific object, situation, or activity that is out of proportion to the actual risk.
A phobia is an intense, persistent fear of a specific object, situation, or activity—such as flying, certain animals, or medical procedures—that is out of proportion to the actual risk. Phobias often lead to avoidance, which can shrink a person's life over time. Therapy approaches that include gradual, supported exposure are often very effective.
