What is OCD and Its Symptoms

Obsessive-compulsive disorder (OCD) features a pattern of unwanted thoughts and fears (obsessions) that lead you to do repetitive behaviours (compulsions). These obsessions and compulsions interfere with daily activities and cause significant distress.
OCD often centres around specific themes — for example, an excessive fear of getting contaminated by germs. To ease your contamination fears, you may compulsively wash your hands until they’re sore and chapped.
If you have OCD, you may be ashamed and embarrassed about the condition, but treatment can be effective.

Symptoms

Obsessive-compulsive disorder usually includes both obsessions and compulsions. But it’s also possible to have only obsession symptoms or only compulsion symptoms. You may or may not realize that your obsessions and compulsions are excessive or unreasonable, but they take up much time and interfere with your daily routine and social, school or work functioning.
Obsession symptoms

OCD obsessions are repeated, persistent and unwanted thoughts, urges or images that are intrusive and cause distress or anxiety. You might try to ignore or eliminate them by performing a compulsive behaviour or ritual. These obsessions typically intrude when trying to think of or do other things.

Obsessions often have themes to them, such as:

• Fear of contamination or dirt
• Doubting and having difficulty tolerating uncertainty
• Needing things orderly and symmetrical
• Aggressive or horrific thoughts about losing control and harming yourself or others
• Unwanted thoughts, including aggression or sexual or religious subjects

Examples of obsession signs and symptoms include:

• Fear of being contaminated by touching objects others have touched
• Doubts that you’ve locked the door or turned off the stove
• Intense stress when objects aren’t orderly or facing a certain way
• Images of driving your car into a crowd of people
• Thoughts about shouting obscenities or acting inappropriately in public
• Unpleasant sexual images
• Avoidance of situations that can trigger obsessions, such as shaking hands Compulsion symptoms

OCD compulsions are repetitive behaviours that you feel driven to perform. These repetitive behaviours or mental acts are meant to reduce anxiety related to your obsessions or prevent something bad from happening. However, engaging in the compulsions brings no pleasure and may only temporarily relieve anxiety.

You may make up rules or rituals to help control your anxiety when you have obsessive thoughts. These compulsions are excessive and often are not realistically related to the problem they intend to fix. As with obsessions, compulsions typically have themes, such as:

• Washing and cleaning
• Checking
• Counting
• Orderliness
• Following a strict routine
• Demanding reassurance

Examples of compulsion signs and symptoms include:

• Hand-washing until your skin becomes raw
• Checking doors repeatedly to make sure they’re locked
• Checking the stove repeatedly to make sure it’s off
• Counting in certain patterns
• Silently repeating a prayer, word or phrase
• Arranging your canned goods to face the same way

When to see a doctor

There’s a difference between being a perfectionist — someone who requires flawless results or performance, for example — and having OCD. OCD thoughts aren’t simply excessive worries about real problems in your life or like to have things clean or arranged in a specific way. See your doctor or mental health professional if your obsessions and compulsions affect your quality of life.
