OCD has two parts. Obsessions are unwanted, intrusive thoughts, images or urges that cause intense distress. Compulsions are the things you do — physically or mentally — to reduce that distress or prevent something feared.
It is not about being tidy, and the casual use of "a bit OCD" to mean organised does real harm, because it makes a severe and disabling condition sound like a personality quirk. That is one reason people wait an average of around a decade before seeking help.
The most important thing on this page is this: intrusive thoughts are universal. Studies consistently find that almost everyone experiences disturbing, violent, sexual or blasphemous thoughts that arrive uninvited. The difference in OCD is not the thought — it is the meaning attached to it, and the effort spent trying to neutralise it.
And the point that matters most, because it keeps people silent for years: having a distressing thought about harming someone means you will not do it. The distress is the evidence. Thoughts that horrify you are, by definition, at odds with who you are — which is exactly why they stick. People with harm obsessions are not dangerous, and this is well established.
Compulsions are not always visible, and mental compulsions are frequently missed:
Most people with OCD know the fears are irrational, which is part of what makes it so distressing — insight does not reduce the compulsion to act. The condition consumes hours a day and produces considerable shame.
OCD runs on a loop that is simple to describe and hard to break:
The compulsion is what keeps the condition alive. Every time it works, it strengthens the belief that it was necessary.
Intrusive thoughts about harming your baby are extremely common after birth. They are horrifying, and mothers frequently do not disclose them for fear their child will be taken away.
This is worth being completely clear about. Perinatal OCD is a recognised anxiety condition, it is treatable, and the thoughts are ego-dystonic — they distress you precisely because they are the opposite of what you want. Women with perinatal OCD are not a risk to their babies, and disclosing is safe.
It is different from postpartum psychosis — where someone believes the thoughts, has lost touch with reality, or feels compelled to act. That is a medical emergency, and it is covered in the urgent section.
OCD is diagnosed clinically, and the main obstacle is not diagnostic difficulty — it is disclosure. Many people describe only the compulsions, or the anxiety, and never mention the thoughts.
No test diagnoses OCD. Where anxiety symptoms are prominent, thyroid function and a full blood count are worth checking, since an overactive thyroid produces overlapping symptoms.
A caution: where health-related obsessions are part of the picture, repeated testing becomes part of the problem. Each normal result relieves anxiety briefly and reinforces the need to check. Thorough assessment once, then treating the OCD, is better care than a scan every few months.
Understanding that intrusive thoughts are universal, that their content is meaningless, and that the compulsion is what sustains the condition shifts things considerably on its own. For many people, being told plainly that harm thoughts do not indicate danger is the first relief in years.
ERP is the most effective treatment for OCD, with strong evidence. It involves deliberately encountering the trigger and not performing the compulsion, allowing the anxiety to rise and then fall on its own.
That teaches something no amount of reasoning can: the anxiety subsides without the ritual, and the feared outcome does not happen. It is uncomfortable, it is done gradually, and it works.
You can self-refer to NHS Talking Therapies free, without a GP. Ask specifically for OCD-focused CBT with ERP, since generic counselling is considerably less effective for this.
SSRIs are effective for OCD, and two points are routinely got wrong:
A great many people conclude an SSRI has failed for their OCD when it was stopped too early or never reached an effective dose.
Severe OCD, symptoms not responding to therapy plus an adequate SSRI trial, or significant risk goes to specialist mental health services. Specialist OCD services exist, and clomipramine and augmentation strategies are options there.
Where reassurance-seeking is part of your OCD, we will say so rather than simply reassuring you. Repeatedly confirming that you have not done something terrible feels kind and feeds the loop. We will explain what we are doing and why, rather than quietly withholding — but we will not become another compulsion.
Call 999 or go to A&E immediately if:
Seek emergency help if intrusive thoughts are believed rather than resisted — if someone feels the thoughts are instructions, has lost touch with reality, is hearing voices, or feels drawn towards acting rather than horrified. That is a different condition and a medical emergency.
In OCD, the thoughts are unwanted and distressing, and that is not an emergency. It is a reason to seek treatment, not a reason for alarm.
Intrusive thoughts about harm coming to your baby are common in perinatal OCD, they are treatable, and disclosing them is safe. You will not have your child removed for having distressing thoughts you do not want. Please tell someone.
Seek emergency help urgently if a new mother is confused, hearing voices, holding unusual beliefs, severely agitated, not sleeping at all, or seems detached from reality — postpartum psychosis is a medical emergency and needs same-day assessment.
Book a consultation if: obsessions or compulsions take up significant time; they affect work, relationships or daily life; you are avoiding things; you have been on an SSRI without benefit — ask whether the dose was high enough and given long enough; or you have never told anyone what the thoughts actually are.
The compulsion is the problem, not the thought. Every time a ritual reduces anxiety, it teaches the brain that the danger was real. Resisting is uncomfortable and is precisely the treatment.
Accommodating the OCD makes it worse, however loving the intention. Providing reassurance, taking over avoided tasks, or participating in rituals all strengthen the condition.
Withdrawing that support should be done with the person, gradually and agreed in advance, not imposed. Family involvement in treatment is genuinely valuable.
People wait an average of around ten years before seeking help for OCD, almost entirely because of shame about the content of the thoughts. Clinicians who treat OCD have heard every theme there is, and none of it will be met with alarm.
The treatment for OCD is specific, and it is not general counselling. It is CBT with exposure and response prevention — ERP — and that distinction matters enormously, because generic talking therapy can be unhelpful in OCD and reassurance-based approaches actively make it worse.
NHS Talking Therapies takes self-referrals without a GP appointment and provides ERP free. Ask specifically for ERP rather than counselling.
SSRIs work in OCD, and the doses used are usually higher than for depression, with a longer time to respond — often 10 to 12 weeks rather than 4 to 6. That is a very common reason people conclude medication has failed when it has simply not been given long enough or at a sufficient dose.
Fluoxetine and sertraline are both cheap generics, free on the NHS.
Where a private consultation genuinely earns its fee is that conversation — explaining the dose and timescale properly, and pushing for ERP rather than accepting generic therapy.
The other thing worth saying: OCD is frequently hidden for years because the intrusive thoughts feel shameful. Thoughts about harm, contamination or taboo subjects are a symptom of the illness, not a reflection of character — and they are extremely common in OCD.
Free and good: OCD Action and OCD-UK provide support and information at no cost.
NICE CG31, Obsessive-compulsive disorder and body dysmorphic disorder, is the governing guideline. It recommends a stepped-care model with CBT including exposure and response prevention (ERP) as the core psychological treatment.
CG31 recommends SSRIs for moderate to severe OCD, noting that higher doses than those used in depression are often required and that response may take 12 weeks or longer — the basis for the point above.
CG31 recommends clomipramine where SSRIs are ineffective or not tolerated, and referral to specialist services for treatment-resistant OCD.
CG31 advises against relying on reassurance, since reassurance-seeking is a compulsion that maintains the disorder.
CG31 also addresses the shame and secrecy that delay presentation, and recommends direct sensitive questioning about intrusive thoughts and compulsions.
No — and the distress is the evidence. Intrusive thoughts in OCD are ego-dystonic: they horrify you precisely because they are the opposite of who you are, which is why your mind keeps returning to them. People with harm obsessions do not act on them, and this is well established. The fear of being dangerous is a symptom of the condition, not a warning about it.
No, and the casual use of the phrase does real damage. OCD is a distressing, time-consuming condition that frequently involves no cleaning at all — harm thoughts, taboo thoughts, relentless checking, mental reviewing. Describing an organised person as "a bit OCD" is part of why people wait years before asking for help.
Two very common reasons. OCD usually needs a higher dose than depression, often at the upper end of the licensed range. And it takes up to 12 weeks rather than four to six. Most people who conclude medication failed were on too low a dose, or stopped at week six.
Exposure and response prevention: deliberately encountering the thing that triggers the obsession and not performing the compulsion. You learn by experience that the anxiety falls on its own and the feared outcome does not occur. It is done gradually, it is uncomfortable, and it is the most effective treatment available.
Yes — and it is one of the most common and least recognised. Reassurance works exactly like handwashing: relief for a few minutes, then a stronger urge to ask again. That includes searching online and requesting repeated medical tests. Stopping it is one of the most powerful changes available.
No. Intrusive thoughts about harm coming to a baby are a common feature of perinatal OCD. They are distressing precisely because they are the opposite of what you want, and they are treatable. Health professionals understand this distinction well. Please tell someone — the silence is far more harmful than the disclosure.
OCD is usually a long-term condition that fluctuates, but it responds well to treatment. Many people get to the point where it is a minor background feature rather than something running their day. The combination of ERP and an adequately dosed SSRI is effective for the majority.
No — thought suppression reliably backfires. Trying not to think about something makes it more frequent and more salient, and the effort of pushing it away is itself a mental compulsion. The approach that works is noticing the thought, labelling it, and declining to engage with it.

Same-day access is usually available, from 6am to 10pm, seven days a week. You choose a time that suits you rather than waiting on hold at 8am.
Yes. Care is led personally by Dr Mohammad Khan, so you are not passed between clinicians. Continuity is the point of a small practice: someone who knows your history and is listening attentively rather than working through a checklist.
Yes, with your consent. We can access your Summary Care Record during the consultation, so your current medications, allergies and significant history are in the room. That means fewer questions you have already answered elsewhere, and safer prescribing.
No. We are not here to replace GPs, only to support them. Your NHS practice remains responsible for your ongoing care, and with your consent we write to them after the consultation. We are useful when you need to be seen sooner, or want more time than a standard appointment allows.
Twenty unhurried minutes and a comprehensive assessment. A written treatment plan is included, along with any prescription, sick note or referral letter arising from the consultation, at no extra charge.
£40 for 20 minutes, self-pay. Membership is optional and never required. Priced for fairness, because we are not here to charge extortionate amounts for access to a doctor.
It means the diagnosis can usually be made from your history and photographs, and that treatment can be arranged safely without examining you. Where a condition is not marked treatable online, it is because examination is the diagnosis — listening to a chest, feeling an abdomen, examining an ear or a joint — or because a procedure or device is needed.
Yes, where there is a genuine bacterial infection — cellulitis, impetigo, bacterial urine infections, confirmed strep throat. We will also frequently tell you that you do not need one. Most sore throats, coughs, colds and earaches are viral, and an antibiotic gives you the side effects with none of the benefit.
If your problem turns out to be genuinely outside what we can do remotely, the doctor will tell you straight away, point you to the right service, and refund your fee in full. We would rather do that than fill twenty minutes to justify the charge.
Call 999 or go to A&E — do not book an online appointment and do not wait for a reply to an email. For urgent problems that are not emergencies, NHS 111 is available 24 hours a day, online or by phone, and can direct you to the right service.
