Science has proved that low self-esteem can cause health problems and diseases.

How Low Self-Esteem Can Cause Health Problems and DiseasesEveryone faces a period of low self-esteem at some point in their lives, but don’t worry; this phenomenon is normal and part of our personality construction.

As a whole, everyone has some low self-esteem in life, but when it becomes the norm, it could result in depression, social anxiety, general anxiety, alcoholism, anorexia, trauma, narcissism, and even euphoric mania. The root cause, lack of self-confidence, can however be tackled with great results.

However, this can become problematic as it impacts us in every aspect; a person may be afraid to leave the house, could give up his job, or even have suicidal thoughts.

Low self-esteem can cause health problems and diseases: Introduction

Currently, the lack of self-confidence is a problem that we encounter more and more.

Indeed, this lack of confidence can be explained not only by events that marked us during our childhood, our education, and our negative experiences but also by the fierce competition that characterizes our society today.

This article will present diseases resulting from a lack of self-confidence.


Depression is the most common illness encountered by people who lack self-confidence. Indeed, the lack of self-confidence seems to be present from the beginning of the disease.

This psychological disorder can be defined by:

  • A permanent sadness with a loss of desire and taste for doing things
  • A lack of will and passion for everything.
  • Difficulty in anticipating the future.

Depression can also be accompanied by physical symptoms such as:

  • A slowdown (you do things more and more slowly)
  • Fatigue
  • Sleep disorders
  • Concentration and memory problems
  • Various physical disorders, etc.

This disease can be somewhat intense, albeit permanent, and can ruin your life for many years: it is called “dysthymia.”

Depression can also evolve through very intense and marked attacks that handicap the lives of those affected. These attacks usually last a few weeks or months and require urgent medical treatment.

Social anxiety, also called social phobia

Social anxiety is the second most frequently encountered illness in people with low self-esteem. In this context, lack of self-confidence seems to be an aggravating factor.

Indeed, social phobia is defined as the fear of others. So if lacking self-confidence with a negative idea of oneself, one will tend to fear the judgment of others and think that others are looking at us the same way we view ourselves.

When these thoughts take hold, people with social anxiety tend to avoid contact with others and withdraw from society, refusing invitations and connections, job promotions, public speaking, etc.

Generalized anxiety disorder

This disorder is also pervasive and affects most of the general population.

Generalized anxiety disorder can be characterized by people who are constantly worrying and fretting about everything.

It seems that there are links between low self-confidence and generalized anxiety.

Symptoms of this disorder may include shaking, excessive sweating or exhaustion.

However, regardless of the symptoms, generalized anxiety will affect the person’s daily activities.

Alcoholism, anorexia and trauma

Many other illnesses may be related to the feeling of being a loser and low self-esteem.

On the other hand, this is the case for some forms of alcoholism, such as:

  • People who drink to self-medicate and confirm their poor self-image
  • People who drink because they are afraid to approach others and think that alcohol helps them open up to others.

Another disease related to the lack of self-confidence is the eating disorder anorexia nervosa, which is very common in young women.

Certain events in our lives can also affect our lack of self-confidence: this is the case of sexual trauma.

Let’s take the example of incest, which causes people subjected to it to have great difficulty accepting their bodies and trusting others in their relationships.

Diseases related to overconfidence

It is interesting to note that there are also illnesses that are related to “too much” self-confidence:

Manic euphoria

In contrast to depression, people who suffer from momentary overconfidence can have what are called “manias.”

This is not the popular meaning of the word “mania” but a real euphoria of the mood that can last for a few weeks.

Indeed, during this manic euphoria, one believes oneself capable of doing everything above others and is hyperactive.

The person has excessive self-confidence and does or says whatever comes into their head, unheeding any consequences.

She will also have a very high opinion of herself and will not take any criticism.


Do you think it’s possible to be overconfident all the time? The answer is yes, and it can too cause problems.

Three types of problems are related to overconfidence:

  • First of all, it may seem suspicious
  • Secondly, this has consequences for the people around them
  • Thirdly, it also has consequences for the person itself.

If you meet someone who looks pretty confident, don’t assume they are psychologically sound. Indeed, there are two types of confident people:

  • The ones that really are. In this case, you don’t need to try to fit in next to them because they respect you, let you speak, see your positive sides and help you progress.
  • The “False Confident” people who need to dominate to exist. For them, you don’t exist, they don’t let you speak, and they haven’t taken the time to appreciate your qualities. They do things for you, and when you try to get started, they criticize you.

In general, these personalities need to dominate for reassurance because their self-esteem is very fragile, contrary to appearances.

Through the domination of the other, they will try to gain confidence in themselves.

Narcissistic people’s self-esteem is social; that is, they depend on the impression of dominance they give others to feel confident.

In addition, they have very low personal self-esteem and can be easily destabilized when challenged.

Consequences for others

When you find yourself around these people, you feel belittled, annoyed, and like a total loser.

They give you the impression that they know everything but never share their knowledge. They just talk about themselves all the time and start most of their sentences with “I.”

Consequences for themselves

Inside, these people do not live the emotions one could imagine.

Indeed, they are incredibly fearful and dread any criticism or defeat that could destabilize them. Instead, they crave approval and compliments from others, which is borderline similar to addiction.

Therefore, since these people only look for positive messages, they cannot progress because no constructive criticism is available.

Low self-esteem can cause health problems and diseases: Conclusion

In conclusion, the lack of self-confidence is a basis for several diseases.

However, even if this psychological disorder can have aggravating consequences, it is possible to be treated, and that person can regain self-confidence.
