Understanding OCD

Obsessive-Compulsive Disorder (OCD) is a mental health condition involving obsessions and compulsions that can cause significant distress and interfere with everyday life.

Obsessions are unwanted thoughts, images, urges or doubts that repeatedly enter someone’s mind and can create anxiety or discomfort. Compulsions are behaviours or mental acts someone feels driven to perform, often in an attempt to reduce that distress or prevent something feared from happening.

OCD is much more complex than simply liking things clean, organised or arranged in a particular way. Understanding this is an important step towards challenging common misconceptions about the condition.

What Are Obsessions?

Obsessions can involve intrusive and unwanted thoughts, images, urges or doubts. They can feel upsetting, frightening, confusing or completely inconsistent with someone’s values and personality.

The subject of an obsession can vary considerably between people. What makes OCD particularly difficult isn’t necessarily the presence of an unwanted thought itself, but the distress, uncertainty and meaning that can become attached to it.

Having an intrusive thought does not mean someone wants it to happen or intends to act on it.

What Are Compulsions?

  • Checking

    Repeatedly checking things such as doors, appliances, messages or whether something has happened.

  • Cleaning & Washing

    Repeated washing or cleaning driven by fears or feelings of contamination.

  • Repeating

    Repeating an action, phrase or behaviour until it feels correct or until anxiety temporarily reduces.

  • Seeking Reassurance

    Repeatedly asking other people for reassurance about a fear, memory, decision or intrusive thought.

  • Mental Compulsion

    Compulsions aren’t always visible. Someone might repeatedly review memories, count, mentally repeat phrases or try to replace a distressing thought.

  • Avoidance

    Someone may begin avoiding particular places, people, objects or situations because they trigger obsessions and anxiety.

How Doe’s OCD Become A Cycle?

OCD can develop into a repeating cycle. An intrusive thought, image, urge or doubt may trigger anxiety or distress. The person then performs a compulsion or seeks certainty in an attempt to make themselves feel safer.

The compulsion may provide temporary relief, but the uncertainty or fear eventually returns. This can create pressure to perform the compulsion again.

Over time, this cycle can become increasingly disruptive and consume significant amounts of someone’s time and energy.

There Isn’t Just One Type Of OCD

OCD isn’t limited to contamination fears or repeatedly checking whether a door is locked.

Obsessions can involve many themes, including responsibility, harm, relationships, morality, contamination, mistakes, identity or fears surrounding uncertainty.

Some people’s compulsions are clearly visible, while others experience primarily mental rituals that people around them may never notice.

The content of someone’s OCD does not define their character. What matters is recognising the pattern of obsessions, distress and compulsive responses rather than judging someone by the subject of their intrusive thoughts.

OCD Can Be Treated

OCD can have a significant impact on someone’s wellbeing, relationships, education, work and everyday life, but effective treatment and support are available.

One of the main evidence-based psychological treatments for OCD is Cognitive Behavioural Therapy (CBT) incorporating Exposure and Response Prevention (ERP). Medication may also be considered in some circumstances through an appropriate healthcare professional.

If OCD is affecting your everyday life, speaking to a GP or qualified mental health professional can be an important step towards accessing appropriate support.
