The anxiety caused by a phobic disorder can interfere with daily living because people avoid certain activities and situations.
The diagnosis is usually obvious based on symptoms.
Treatment usually consists of exposure therapy.

The most common specific phobias include fear of animals (zoophobia), fear of heights (acrophobia), and fear of thunderstorms (astraphobia or brontophobia).

Some specific phobias cause little inconvenience. For example, a city dweller who is afraid of snakes may have no trouble avoiding them. Other specific phobias greatly interfere with functioning. For example, a city dweller who fears elevators may encounter them frequently and thus be routinely faced with a difficult choice: avoid an important work situation, climb many stairs, or endure the elevator ride with great discomfort.

Treatment of Specific Phobic Disorders
Some people do well without treatment because the situation or object they fear is easy to avoid. Bats and caves are examples. If situations or objects (such as thunderstorms) are commonly encountered, treatment is often needed.
Exposure therapy, a type of psychotherapy, is the treatment of choice. Exposure therapy involves exposing people gradually and repeatedly—in their imagination or sometimes in reality—to whatever triggers their fear. People are also taught relaxation and/or breathing techniques to use before and during exposure. Exposure therapy is repeated until people become very comfortable with the anxiety-provoking situation. A therapist can help ensure that the therapy is carried out correctly, although people can do it on their own.
Exposure therapy helps more than 90% of people who do it faithfully. It is almost always the only treatment needed for specific phobias. Even people with a phobia of blood or needles respond well to exposure therapy. For example, such people might begin the exposure by just visiting a doctor's office (or perhaps just walking by the office). The next day (or week), they might sit in an exam room with no intention of getting any blood drawn. The next step might be allowing a needle to be brought close to their skin. Exposure may increase quickly or slowly, but eventually people should allow blood to be drawn.
Drug therapy is not very useful in helping people overcome specific phobias. One exception is the use of benzodiazepines (antianxiety drugs) for some specific phobias. For example, people with flying phobias may use a benzodiazepine prior to boarding the plane. The benzodiazepine alone does not generally eliminate the phobia, but it does allow the person to fly.
