Obsessive-compulsive disorder (OCD) is a mental health condition where a person has obsessive thoughts and compulsive behaviours. OCD can affect men, women and children.
People can start having symptoms from as early as 6 years old, but it often begins around puberty and early adulthood. OCD can be distressing and significantly interfere with your life, but treatment can help you keep it under control.
Obsessive compulsive disorder (OCD) affects people differently, but usually causes a particular pattern of thoughts and behaviours.
OCD has 3 main elements:
The compulsive behaviour temporarily relieves the anxiety, but the obsession and anxiety soon return, causing the cycle to begin again.
Most people with OCD experience both obsessive thoughts and compulsions, but one may be less obvious than the other.
Obsessive thoughts
Almost everyone has unpleasant or unwanted thoughts at some point, such as thinking they may have forgotten to lock the door of the house, or even sudden unwelcome violent or offensive mental images.
But if you have a persistent, unpleasant thought that dominates your thinking to the extent it interrupts other thoughts, you may have an obsession.
Some common obsessions that affect people with OCD include:
You may have obsessive thoughts of a violent or sexual nature that you find repulsive or frightening. But they’re just thoughts and having them does not mean you’ll act on them.
These thoughts are classed as OCD if they cause you distress or have an impact on the quality of your life.
Compulsive behaviour
Compulsions start as a way of trying to reduce or prevent anxiety caused by the obsessive thought, although in reality, this behaviour is either excessive or not realistically connected.
For example, a person who fears contamination with germs may wash their hands repeatedly, or someone with a fear of harming their family may have the urge to repeat an action multiple times to “neutralise” the thought.
Most people with OCD realise that such compulsive behaviour is irrational and makes no logical sense, but they cannot stop acting on it and feel they need to do it “just in case”.
Common types of compulsive behaviour in people with OCD include:
Not all compulsive behaviours will be obvious to other people.
It’s important to get help if you think you have OCD and it’s having a significant impact on your life.
If you think a friend or family member may have OCD, try talking to them about your concerns and suggest they get help.
OCD is unlikely to get better on its own, but treatment and support is available to help you manage your symptoms and have a better quality of life.
People with OCD are sometimes 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.
It’s unlikely OCD will get better without proper treatment and support.
Obsessive compulsive disorder (OCD) can be treated. The treatment recommended will depend on how much it’s affecting your life.
The 2 main treatments are:
A short course of therapy is usually recommended for relatively mild OCD. If you have more severe OCD, you may need a longer course of combined therapy and medicine.
These treatments can be very effective, but it’s important to be aware that it can take several months before you notice the benefit.
You can get treatment on the NHS through a GP.
You can also refer yourself directly to an NHS talking therapies service without a referral from a GP.
Therapy for OCD is usually a type of cognitive behavioural therapy (CBT) with exposure and response prevention (ERP).
This involves:
The treatment may be hard work, but many people find that when they confront their obsessions, the anxiety eventually improves or goes away.
People with fairly mild OCD usually need about 8 to 20 sessions of therapist treatment, with exercises done at home between sessions. If you have more severe OCD, you may need a longer course of treatment.
You may need medicine if talking therapy does not help treat your OCD, or if your OCD is fairly severe.
The main medicines prescribed are a type of antidepressant called selective serotonin reuptake inhibitors (SSRIs). An SSRI can help improve OCD symptoms by increasing the levels of a chemical called serotonin in your brain.
You may need to take an SSRI for up to 12 weeks before you notice any benefit.
Most people need treatment for at least a year. You may be able to stop if you have few or no troublesome symptoms after this time, although some people need to take an SSRI for many years.
Do not stop taking an SSRI without speaking to your doctor first because suddenly stopping can cause unpleasant side effects. Treatment will be stopped gradually to reduce the chance of getting side effects. Your dose may need to be increased again if your symptoms return.
Side effects
Possible side effects of SSRIs include:
There’s also a very small chance that SSRIs could cause you to have suicidal thoughts or want to self-harm. If this happens, contact a GP or go to your nearest accident and emergency (A&E).
Most side effects improve after a few weeks as your body gets used to the medicine, although some can persist.
Pregnancy
SSRIs are not usually recommended during pregnancy. There are risks to the baby during the first 3 months (1st trimester) and last 3 months (3rd trimester).
However, exceptions can be made if the risk posed by a mental health condition outweighs the potential risks of treatment.
Further treatment by a specialist team may sometimes be necessary if you’ve tried talking therapy and medicine and your OCD is still not under control.
Some people with severe, long-term and difficult-to-treat OCD may be referred to a national specialist OCD service.
These services offer assessment and treatment to people with OCD who have not responded to treatments available from their local and regional OCD services.
OCD UK has more information about NHS Specialist OCD Treatment Services, including adult and child and adolescent services.
Many people with OCD find support groups helpful, as they can:
The national charities OCD Action, OCD-UK and TOP UK can provide information about support groups in your area:
