People with OCD experience intrusive and persistent thoughts, impulses, or images (obsessions) and often feel compelled to perform certain rituals or routines (compulsions).

Common obsessions associated with OCD include a fear of contamination by germs, the need for order or symmetry, the fear of harm coming to oneself or others, and the need for excessive control over thoughts and feelings. Common compulsions include counting rituals, excessive washing and cleaning, organizing activities such as straightening objects in specific ways, repeating words in one's head over and over again, and seeking reassurance about issues repeatedly.

These obsessions and compulsions cause anxiety for those who have OCD which can be overwhelming and debilitating. If left untreated, OCD can interfere with daily activities and disrupt relationships with friends and family members. Thankfully, there are treatment options available that can help people manage their symptoms. Cognitive-behavioral therapy is the most common form of treatment for OCD but medications like antidepressants may also be used in combination with therapy. With proper treatment many people find relief from their symptoms allowing them to live a more fulfilling life.
