Obsessive-compulsive disorder (OCD) features a pattern of unwanted thoughts and fears known as obsessions. These obsessions lead you to do repetitive behaviors, also called compulsions. These obsessions and compulsions get in the way of daily activities and cause a lot of distress.

Ultimately, you feel driven to do compulsive acts to ease your stress. Even if you try to ignore or get rid of bothersome thoughts or urges, they keep coming back. This leads you to act based on ritual. This is the vicious cycle of OCD.

OCD often centers around certain themes, such as being overly fearful of getting contaminated by germs. To ease contamination fears, you may wash your hands over and over again until they're sore and chapped.

If you have OCD, you may be ashamed, embarrassed and frustrated about the condition. But treatment can be effective.
