OCD Cause's

The cause of obsessive-compulsive disorder isn't fully understood. Main theories include:

Biology. OCD may be a result of changes in your body's own natural chemistry or brain functions. OCD also may have a genetic component, but specific genes have yet to be identified.

Environment. OCD may stem from behavior-related habits that you learned over time.

Insufficient serotonin. An insufficient level of serotonin, one of your brain's chemical messengers, may contribute to obsessive-compulsive disorder. In addition, people with obsessive-compulsive disorder who take medications that improve the action of serotonin often have fewer OCD symptoms.
