Factors that may increase the risk of developing or triggering obsessive-compulsive disorder include:

  • Family history. Having parents or other family members with the disorder can increase your risk of developing OCD.
  • Stressful life events. If you've experienced traumatic or stressful events or you tend to react strongly to stress, your risk may increase. This reaction may, for some reason, trigger the intrusive thoughts, rituals and emotional distress characteristic of OCD.
