Obsessive-compulsive disorder (OCD) is a mental health condition characterised by recurring unwanted thoughts, fears, or urges known as obsessions. These thoughts can lead a person to repeat certain behaviours or mental routines, known as compulsions. When these patterns become difficult to control, they can interfere with everyday activities and quality of life.

OCD often creates a cycle of anxiety and repetitive behaviour. A person may experience an unwanted thought, feel distressed by it, and then perform a particular action to gain temporary relief. However, the thought may return, causing the cycle to begin again.

Common OCD symptoms can involve fears of germs or contamination, excessive concern about mistakes, a strong need for order, or persistent doubts about whether something has been done correctly. Some people may also experience intrusive thoughts or images that they find disturbing or inconsistent with their values. Having such thoughts does not mean that a person wants to act on them.

Compulsions can include repeated washing, checking, counting, arranging objects, following rigid routines, silently repeating words or phrases, or repeatedly seeking reassurance. These behaviours are usually performed to reduce distress rather than for enjoyment, and any relief may be temporary.

OCD symptoms can vary considerably from person to person. They may begin during childhood, adolescence, or adulthood and can become more noticeable during periods of stress or major life changes. For some people, symptoms are mild, while for others they can consume significant amounts of time and disrupt daily responsibilities.

Understanding OCD is an important step towards reducing the shame and misunderstanding surrounding the condition. With greater awareness and appropriate professional support, people experiencing OCD can work towards managing its impact and improving their quality of life.
