Obsessive-compulsive disorder is one of top three mental disorders in Singapore. About 3 per cent of the adult population will suffer from OCD during their lifetime, according to the Singapore Mental Health Study (2010).

Obsessive-compulsive disorder (OCD) is a mental illness that causes repeated unwanted thoughts or sensations (obsessions) or the urge to do something over and over again (compulsions). Some people can have both obsessions and compulsions.

OCD isn’t about habits like biting your nails or thinking negative thoughts. An obsessive thought might be that certain numbers or colours are “good” or “bad.” A compulsive habit might be to wash your hands seven times after touching something that could be dirty. Although you may not want to think or do these things, you feel powerless to stop.

Everyone has habits or thoughts that repeat sometimes. People with OCD have thoughts or actions that:

Take up at least an hour a day

Are beyond your control

Aren’t enjoyable

Interfere with work, your social life, or another part of life

OCD Types and Symptoms

OCD comes in many forms, but most cases fall into at least one of four general categories:

Checking, such as locks, alarm systems, ovens, or light switches, or thinking you have a medical condition like pregnancy or schizophrenia

Contamination, a fear of things that might be dirty or a compulsion to clean. Mental contamination involves feeling like you’ve been treated like dirt.

Symmetry and ordering, the need to have things lined up in a certain way

Ruminations and intrusive thoughts, an obsession with a line of thought. Some of these thoughts might be violent or disturbing.
