Obsessive compulsive disorder (OCD) is a common mental health condition where a person has obsessive thoughts and compulsive behaviours.
OCD can affect men, women and children. Some people start having symptoms early, often around puberty, but it usually starts during early adulthood.
OCD can be distressing and significantly interfere with your life, but treatment can help you keep it under control.
If you have OCD, you'll usually experience frequent obsessive thoughts and compulsive behaviours.
For example, someone with an obsessive fear of being burgled may feel they need to check all the windows and doors are locked several times before they can leave their house.
Women can sometimes have OCD during pregnancy or after their baby is born. Obsessions may include worrying about harming the baby or not sterilising feeding bottles properly. Compulsions could be things such as repeatedly checking the baby is breathing.
People with OCD are often reluctant to seek help because they feel ashamed or embarrassed.
OCD is a health condition like any other, so there's nothing to feel ashamed or embarrassed about. Having OCD does not mean you're "mad" and it's not your fault you have it.

Some people may be referred to a specialist mental health service for further treatment.
