OCD Subtypes

Beyond Cleanliness: Understanding OCD Subtypes

When people think of Obsessive-Compulsive Disorder (OCD), it’s common to hear phrases like, “Your house must be so clean!” or “I’m kind of OCD about keeping things tidy.” These comments, though often well-meaning, reflect a limited view of what OCD truly is.


While cleanliness and order can be part of some people’s OCD experience, they represent just one subtype. In reality, OCD is a complex and often misunderstood condition that can manifest in many different forms, known as subtypes. Educating ourselves about these subtypes can help us better understand ourselves or our loved ones, recognize when professional support may be helpful, and most importantly, reduce shame by showing that we’re not alone.


Let’s take a look at some of the most common OCD subtypes. Keep in mind - this isn’t an exhaustive list. OCD can attach itself to virtually any thought pattern. And remember: these thoughts are intrusive, unwanted, and deeply distressing. They do not reflect a person’s desires, intentions, or values.

  • Health/Contamination OCD - the one most people think of!

    • Fear of being harmed or harming others through exposure to dirt, germs, chemicals, or other contaminants. Fear can also present in regards to having an untreatable medical condition despite medical testing/reassurance to the contrary.
