What is chronic fatigue?

There are many individuals who would like to stay a little longer in bed before going to work in the office, or enjoy a nap for its physical and psychological benefits. However, there are people who spend all day in "off", tired, decentered, unmotivated ... When this feeling of tiredness does not disappear and manifests itself for a long period of time, there may be a problem that feeds it (depression, burnout, insomnia, etc.).

Chronic fatigue makes the person feel very tired throughout the day and have difficulties when carrying out their daily tasks. It is similar to spring asthenia, which usually appears together with a decrease or alteration in the immune system for different reasons , like the typical allergies of this time of the year. However, chronic fatigue can occur at different times of the year producing a physical and mental weakening of the subject.

In fact, chronic fatigue is considered a symptom of underlying problems, often due to physical but also psychological illnesses.

As I have said, chronic fatigue is usually considered a set of symptoms that have their origin in other types of problems that can be physical or psychological. Among them, the following stand out.

Burnout is what is known as chronic stress and causes the person to feel burned . After suffering a period of prolonged stress, the person exhausts their resources and then the demotivation and extreme tiredness appear.

Lack of motivation

Depression or burnout can cause a lack of motivation , but demotivation can also occur because a person does not have realistic goals or does not see his future clear, so he can enter into an existential crisis that ends up exhausting him mentally.

Neurological disorders

Use of medications

The use of some medications as a side effect can cause symptoms of fatigue , for example, benzodiazepines or antipsychotics. Therefore it is necessary to inform the doctor or psychiatrist if the symptoms appear after the beginning of the pharmacological treatment to make possible the substitution.


Since there are many causes that can cause chronic fatigue, this phenomenon requires different ways of treatment. In most cases, the subjects go to the family doctor to make a diagnosis, but the diagnosis should not focus only on physical diseases (urine samples, blood tests) and the treatment should not always be the administration of drugs, but psychological therapy and, sometimes, a visit to a nutritionist dietitian can help treat chronic fatigue .

Logically, when the causes are of psychological origin, such as depression or stress, it is necessary to go to a psychology professional to be able to deal with the underlying problem. There are different types of psychotherapy that can be effective, for example, cognitive behavioral therapy, cognitive therapy based on Mindfulness (MBCT) or acceptance and commitment therapy (ACT).

In cases in which the poor diet or the individual suffers from anemia, it is advisable to go to a dietitian nutritionist to solve the problem.
