Chronic Fatigue Syndrome: Symptoms, Causes, Diagnosis & Treatment 



Do you ever feel so exhausted that it seems like no amount of sleep or rest can shake the tiredness? If this is a common occurrence in your life, then you may be experiencing chronic fatigue syndrome (CFS). The condition affects millions of people worldwide and can be debilitating for those who suffer from it. In this blog post, we'll dive into the symptoms, causes and treatment options available for chronic fatigue syndrome. This will help you better understand this often-misunderstood ailment. 

What is Chronic Fatigue Syndrome?

Chronic fatigue syndrome or myalgic encephalomyelitis is a condition that causes you to feel extremely tired and weak. CFS can have a major impact on your quality of life, making it difficult to work, socialise or take part in hobbies and activities you enjoy.

Symptoms of Chronic Fatigue Syndrome

The main symptom of chronic fatigue syndrome or myalgic encephalomyelitis is constant tiredness that doesn’t go away with rest or sleep. Other symptoms include:

  • Muscle pain
  • Joint pain
  • Headaches
  • Sore throat
  • Difficulty concentrating
  • Memory problems

These symptoms can make it hard to do your normal activities. CFS can last for months or years and can come and go in cycles. Although there is no known cure for chronic fatigue syndrome, treatments can help manage the symptoms.

Causes of Chronic Fatigue Syndrome

There isn’t a single known cause of chronic fatigue syndrome. There are likely several causes, with different people being susceptible to different triggers.

It’s thought that chronic fatigue syndrome may be the result of a combination of:

  • A Viral Infection – Some people develop chronic fatigue syndrome after having a viral infection, such as glandular fever or Ross River fever. It’s not clear why this happens but the virus may lead to changes in the immune system that make the body more vulnerable to other infections or illnesses.
  • Physical or Emotional Trauma - Some people develop chronic fatigue syndrome after experiencing physical or emotional trauma such as a car accident or the death of a loved one. It’s not clear how trauma might trigger CFS but it may lead to changes in the way the body responds to stress.
  • Hormonal Imbalances - Research suggests that hormonal imbalances may play a role in chronic fatigue syndrome. For example, women with CFS often have higher levels of the hormone cortisol and lower levels of thyroid hormones than women without CFS. It’s not clear how these hormone changes might contribute to CFS but they could be involved in triggering or worsening symptoms.
  • Genetic Factors - Studies suggest that genetic factors may make some people more susceptible to developing CFS. For example, people with certain genes involved in the immune system seem to be more likely to develop CFS than those without these genes.

Diagnosis of Chronic fatigue syndrome

Diagnosis of chronic fatigue syndrome is typically made based on symptoms, medical history and a physical exam. The most commonly used criteria for diagnosing CFS is the International Classification of Diseases (ICD-10). It requires that patients have at least six months of unexplained, severe fatigue accompanied by other symptoms such as cognitive impairment, muscle or joint pain, headache, sleep disorders or post-exertional malaise (tiredness after any activity or exertion).

Additional laboratory tests may be done to rule out other potential causes of the symptoms.

Risk Factors for Chronic Fatigue Syndrome

Here are some of the factors that can increase the risk for chronic fatigue syndrome:

  1. Having an infection such as Epstein-Barr virus, mononucleosis or Lyme disease
  2. Stressful life events or traumatic events
  3. Gender (women are more likely to develop CFS)
  4. Age (CFS is most common in people in their 40s and 50s)
  5. Genetic factors 
  6. Being overweight or obese 
  7. Low levels of physical activity 
  8. Environmental exposure to toxins

Treatment for Chronic fatigue syndrome

There is currently no known cure for chronic fatigue syndrome or myalgic encephalomyelitis. However, several treatments can help to manage the symptoms. The most important thing is to get a diagnosis from a doctor so that you can start receiving treatment.

The main goals of treatment are to reduce fatigue, improve quality of life and maximise function. Treatment usually involves a combination of medication, lifestyle changes and psychological support.

  1. Medication: There is no specific medication for chronic fatigue syndrome, however, certain drugs can be used to help manage symptoms such as pain, sleep problems and anxiety.
  2. Lifestyle changes: Making some simple lifestyle changes can also help to reduce fatigue and improve quality of life. These include getting regular exercise, reducing stress levels, eating a healthy diet and getting enough sleep.
  3. Psychological support: CFS can often harm mental health so it’s important to receive psychological support if needed. This can involve talking therapies such as cognitive behavioural therapy (CBT) or counselling.

Living with Chronic fatigue syndrome

Chronic fatigue syndrome or myalgic encephalomyelitis is a long-term condition that causes extreme tiredness. It can affect all areas of your life including work, socialising and maintaining relationships.

There's no single cause of chronic fatigue syndrome but it's thought to be related to several factors including viral infections, psychological stress and hormonal imbalances. Treatment for CFS usually involves a combination of self-care measures such as exercises, relaxation techniques and medication.

If you're living with chronic fatigue syndrome, it's important to pace yourself and listen to your body. This means not overdoing things – both mentally and physically. You may need to make some lifestyle changes such as reducing your working hours or cutting back on social commitments. It's also important to eat a healthy diet and get regular exercise (even if it's just gentle exercise).


Chronic fatigue syndrome is a debilitating condition that can have an immense impact on your life. From lifestyle changes to medications, there are many ways to reduce the symptoms of chronic fatigue syndrome and improve the overall quality of life. If you believe that you may be suffering from this illness, seek professional medical advice as soon as possible.
