What is OCD?

When most people think of OCD, they often picture excessive handwashing, checking, or a need for things to be neat and organized.

While those experiences can certainly be part of OCD, many symptoms are much harder to see. At its core, OCD often involves intrusive thoughts, images, urges, sensations, or feelings of doubt that trigger anxiety and a powerful urge to respond.

Obsessions can take many different forms. They may show up as unwanted thoughts, mental images, urges, sensations, or a persistent feeling that something isn't quite right.

Some examples might include:

  • What if I made a mistake and didn't realize it?

  • "What if someone gets hurt because of me?"

  • "What if this thought means something important?"

  • "What if I don't really love my partner?"

  • "What if I'm making the wrong decision?"

  • A mental image that feels disturbing or difficult to dismiss

  • An urge that feels significant, even when you don't want to act on it

  • A persistent feeling that something is incomplete, off, or "not quite right"

Compulsions are attempts to reduce anxiety, gain certainty, prevent something bad from happening, or simply get a sense of relief from the distressing thoughts, feelings, images, urges, or sensations. The urge to perform a compulsion can feel incredibly strong. Even when part of you recognizes that a compulsion doesn't actually solve the problem, it may still feel difficult or risky not to do it.

Some compulsions are visible, such as:

  • Checking

  • Washing

  • Repeating actions

  • Seeking reassurance from others

  • Avoiding certain situations, places, or objects

Others happen entirely in the mind, such as:

  • Replaying conversations

  • Mentally reviewing events

  • Seeking reassurance

  • Researching symptoms or concerns

  • Trying to "figure out" whether a fear is true

  • Looking for certainty before moving forward

OCD often follows a cycle.

Obsession→ Anxiety, Doubt, or Discomfort → Compulsion → Temporary Relief → Stronger OCD

While compulsions can provide relief in the moment, they also reinforce the idea that the thought, image, urge, or feeling was important and needed a response. Over time, the cycle becomes stronger. OCD can be treated effectively with evidence-based approaches such as Exposure and Response Prevention (ERP), which helps people develop new ways of responding to intrusive thoughts, anxiety, and doubt.
