When the liver is inflamed, these vital processes stop. In addition to being tired, you might experience abdominal pain, jaundice, nausea, dark yellow urine, and light-colored stools.

What are the symptoms of chronic fatigue syndrome (CFS)Psychologic causes of fatigue

Anxiety and Depression

Fear, anxiety, and depression are the most common psychological causes of fatigue. A majority of patients with chronic fatigue also experience mood or anxiety issues, according to medichealth.com. Clinical trials have confirmed that chronic fatigue is a typical form of anxiety or depressive states, meaning that chronic fatigue might be just another form of anxiety or depression.

It is essential to understand that the patient is not faking; his or her complaints are real. Somatization disorder is more common in women than men. Erectile dysfunction is a common complaint in men. Women may experience menstrual irregularities. Patients with somatization problem often undergo numerous clinical examinations before the psychological cause of their distress is identified.

What is chronic fatigue syndrome (CFS)?

Chronic fatigue syndrome (CFS) is a debilitating disorder associated with extreme fatigue or tiredness that doesn’t go away with quality sleep or nutrition and can’t be explained by an underlying medical condition. Sometimes CFS can also be referred to as myalgic encephalomyelitis (ME) or systemic exertion intolerance disease (SEID).

CFS may be challenging to diagnose and cure because the causes of CFS are not known yet and other deceases have similar symptoms. Some studies include viral infection, psychological stress, or a combination of factors. In the past, CFS has been a controversial diagnosis, but nowadays it is widely accepted as a medical condition.

Anyone can suffer CFS, though it’s most common among women in their 40s and 50s. There’s currently no complete cure of CFS, so therapy for CFS focuses on addressing the symptoms. There are no specific tests for chronic fatigue syndrome available, so to figure out your diagnosis your doctor needs to rule out other causes for your fatigue.

What causes chronic fatigue syndrome (CFS)?

The cause of CFS is yet to be known. Researchers make guesses that contributing factors may include:

  • Viruses
  • A weakened immune system
  • Stress
  • Hormonal imbalances

It’s also possible that some people may naturally develop CFS. We are yet to know if CFS is hereditary and contagious. Though CFS can most times develop after a viral infection, no single type of disease has been found to cause CFS, not even speculation. Here are some viral infections that have been studied about CFS include:

  • Epstein-Barr virus (EBV)
  • Human herpesvirus 6
  • Ross River virus (RRV)
  • Rubella

Infections caused by bacteria, including mycoplasma and pneumonia, have also been studied about CFS.

What are risk factors for chronic fatigue syndrome (CFS)?

CFS is most commonly seen among individuals in their 40s and 50s. Gender is also a determining factor as women are two to four times more likely to be diagnosed with CFS than men. Genetic, allergies, stress, and environmental factors may also increase or worsen the severity of CFS.

A recent study had suggested that around 10% of the people with Epstein-Barr virus, Ross River virus, and Coxiella burnetii show symptoms that meet the criteria for a CFS diagnosis. Additionally, people with CFS sometimes have weakened immune systems, but doctors don’t know whether this is enough to cause the disease.

What are the symptoms of chronic fatigue syndrome (CFS)?

The symptoms of CFS differ based on the individual affected and the severity (serious or mild). The most common symptom is strong fatigue that’s severe enough to make you tired and expressly interfere with your daily activities. For CFS to be diagnosed, the patient must have prolonged fatigue which is not curable with bed rest or proper nutrition.

Other symptoms of CFS may include

  • Post-exertional malaise (PEM), where the symptoms get worse after any physical or mental activity
  • Loss of memory or concentration
  • Not feeling fresh after a night’s sleep
  • Swollen lymph nodes in your neck and armpits

The symptoms of CFS might show up in cycles, with periods where affected people sometimes feel worse and then better again.

What to do when diagnosed with chronic fatigue syndrome (CFS)?

What to do when diagnosed with chronic fatigue syndrome (CFS)Of course, it strongly depends on what symptoms you are experiencing and how severe they are, but there is no doubt that you are going to face significant lifestyle changes in order to deal with chronic fatigue.

First of all, you should closely work with your doctor to develop the right treatment plan, including possibly necessary medicines and other therapies. This often works in a way, that together with your doctor you identify the symptoms which cause the most problems first and then start from there.

Complementary therapies such as relaxation therapy or any form of meditation might be helpful. However, important is that you discuss all types of therapy with your doctor or therapist first to exclude potential risks.

If possible also involve your family so that they become familiar with potential (positive or negative) effects of the treatment. The better yourself and the people around you understand the disease the more effectively it can be treated.

Social isolation is by far the worst condition you could be in when diagnosed with CFS, especially if you experience anxiety or depression. Therefore, if you do not have anybody around you who can support you, talk to your doctor or therapist and do not hesitate to join a support group. Also, organizations like the Solve ME/CFS Initiative (SMCI) are providing helpful resources, and the CDC advises on how to manage and live with CFS.
