The Truth About Compulsive Liars: Causes Signs and Support


Understanding Compulsive Liars: What You Need to Know

Have you ever had a friend who just can’t seem to stop lying – even about the smallest things? Maybe you know someone who always embellishes their stories or even invents fake ones.

If so, you might be dealing with a compulsive liar. In this article, we’re going to dive into what compulsive lying is, what causes it, and how to recognize the signs of a compulsive liar.

Let’s get started!

Definition of Compulsive Lying

Compulsive lying, also known as mythomania or pseudologia fantastica, is a behavioral disorder where a person chronically and uncontrollably lies. It’s not just white lies – compulsive liars can lie about anything, regardless of its importance or impact.

Types of Liars

It’s important to note that not all liars are the same. There are three types of liars:

  • Natural liars are people who lie occasionally to avoid trouble or protect their self-interests.
  • Pathological liars, on the other hand, lie more frequently and usually have underlying mental health issues.
  • Compulsive liars, meanwhile, have an irresistible urge to lie that can be compulsive and often stems from deep-seated emotional issues.

Causes of Compulsive Lying

While the exact cause of compulsive lying is unknown, some factors are believed to contribute to it.

Mental Illness

Mental illness, such as bipolar disorder, anxiety, and depression, can play a role in compulsive lying.


Trauma, such as child abuse or neglect, can also lead to this disorder.

Impulse Control Disorders

Impulse control disorders, such as kleptomania and pyromania, can also be a cause of compulsive lying.

Signs of a Compulsive Liar

It can be challenging to recognize someone is a compulsive liar, given they often lie convincingly and persistently. Here are some signs that you might be dealing with a compulsive liar:

  • Inconsistent stories: Compulsive liars often struggle to keep their lies straight, which can lead to contradicting stories.
  • An obsession with their image: They prioritize seeming impressive or successful and always have to be the center of attention in their lies.
  • Lack of guilt: They don’t feel guilty or remorseful about lying, and can often justify their lies with ease.
  • Unnecessary lies: They lie about things that don’t even matter, just to keep the attention on themselves.
  • A history of lying: Compulsive lying is a pattern, so if someone has lied frequently in the past, it’s likely they’ll continue to do so.
  • Unpredictability: You might find it challenging to trust a compulsive liar since their lies are unpredictable and inconsistent.


Compulsive lying is a serious disorder that requires treatment from mental health professionals. Although it can be challenging to identify someone as a compulsive liar, recognizing the signs will help you make informed decisions about how to react to their behavior.

If you know someone who exhibits these signs, encourage them to seek help and support them however you can. Remember, compulsive lying isn’t a conscious choice – it’s a disorder that can be treated with the right help.

In conclusion, it’s important to understand what compulsive lying is, how it differs from other types of lying, and what might cause someone to become a compulsive liar. Recognizing the signs of a compulsive liar and offering support to those who exhibit these behaviors is crucial.

By understanding and empathizing with those who struggle with compulsive lying, it’s possible to help them receive the professional treatment they need to overcome this disorder. As a society, we need to be more understanding and supportive of mental health issues such as compulsive lying, as it can have a severe impact on a person’s wellbeing and relationships.
