OCD subtype guide

Types of OCD and Intrusive Thought Patterns

OCD can attach to many themes, but the underlying loop is often similar: intrusive thoughts, anxiety, compulsions, avoidance, reassurance seeking and temporary relief. Understanding the pattern can make the next step clearer.

Book Confidential Consultation
Checking OCD

The doubt says, "What if I missed something?" The checking gives relief for a moment, then the doubt returns.

Contamination OCD

The fear can make ordinary objects, places or sensations feel unsafe, even when others see no danger.

Existential OCD

Deep questions become distressing when the mind demands certainty that cannot be fully proven.

False Memory OCD

The mind keeps asking, "What if I did something wrong?" even when there is no clear evidence.

Harm OCD

The thought feels terrifying because it goes against your values. The fear is not proof of intent.

Perfectionism OCD

The mind demands that things feel complete, exact or perfect before you can move on.

POCD

Taboo intrusive thoughts can feel terrifying, but intrusive fear is not the same as desire or intent.

Postpartum OCD

A new parent can love their baby deeply and still experience frightening intrusive thoughts.

Pure OCD

Even when compulsions are not visible, the mind may be working hard to neutralise fear.

Relationship OCD

ROCD turns normal relationship uncertainty into urgent doubt that demands perfect answers.

Religious OCD

Faith or values can become painful when OCD demands impossible certainty about morality.

Responsibility OCD

The mind treats ordinary uncertainty as if you must prevent every possible bad outcome.

Sensorimotor OCD

Normal body processes become distressing when attention locks onto them and checks for relief.

Sexuality OCD

OCD can attack identity themes by demanding perfect certainty about attraction or orientation.

Symmetry OCD

The discomfort says something is off, uneven or incomplete until you correct it.

Not sure where you fit?

You do not need to identify the subtype perfectly before getting support.

A consultation can help map the thought loop, compulsions and avoidance patterns so you can understand what is happening and what kind of structured support may help.
