When someone is suffering from OCD, it effects the nervous system. TNS consists of nerves and cells known as neurons that transmit signals between different parts of the body.

OCD is triggered by communication problems between the brain's deeper structures and the front part of the brain.

Obsessive Compulsive Disorder is when a person gets caught in a circle of obsessions and compulsions, resulting in unwanted thoughts, images and triggers that can cause distressed feelings. The person often feels as if everything has to be just right or are consumed by doubt, fear and disgust.  

There are multiple symptoms and obsessions such as:

• Contamination (body fluids or germs) 
• Unwanted sexual thoughts or impulses 
• Religious obsessions (concern with
• offending God)
• Harm (Others, themselves or being responsible) 
• Perfectionism 

There is no cure for OCD but many people that suffer from it use medications such as antidepressants or even psychotherapy such as CBT. It allows them to be exposed to whatever they fear and learn how to handle anxiety

OCD could get worse if not treated with medication, resulting in physical problems and issues with how the brain functions. Which in extreme cases could lead to suicidal thoughts.
