  • What exactly is obsessive-compulsive disorder (OCD)?
    MedlinePlusMay 2026

    OCD is a mental disorder where you have unwanted thoughts (called obsessions) and feel driven to do repetitive actions (called compulsions) over and over. These thoughts and actions interfere with your daily life, but you can't control or stop them even though you want to.

  • Why do I have OCD if it runs in my family?
    MedlinePlusMay 2026

    Having a family member with OCD increases your risk of developing it, but it doesn't mean you will definitely get it. Genetics is just one factor—your brain chemistry, environment, and other things also play a role in whether OCD develops.

  • How does OCD affect daily life and routines?
    MedlinePlusMay 2026

    OCD can make it hard to focus on school, work, or spending time with friends because the obsessions and compulsions take up so much time and mental energy. Daily routines like getting ready, eating, or sleeping may become difficult or take much longer than usual.

  • Can stress or trauma trigger OCD symptoms?
    MedlinePlusMay 2026

    Stress and trauma can sometimes trigger or worsen OCD symptoms, though the exact cause of OCD isn't fully understood. Factors like genetics, brain chemistry, and environment all play a role in developing OCD.

  • Are there different types of obsessions and compulsions?
    MedlinePlusMay 2026

    Yes, there are many different types of obsessions (like fears of germs, harm, or unwanted thoughts) and compulsions (like excessive cleaning, checking, arranging, or counting). People with OCD may have one type or a combination of different obsessions and compulsions.
