Chronic Fatigue Syndrome: Causes, Symptoms and Treatment

Living with Chronic Fatigue Syndrome (CFS) can feel overwhelming and isolating, and it is more common than what most people think. Globally, millions of individuals are affected by CFS. Unfortunately, there is still not much awareness about this growing health concern. That’s why in this article, we aim to provide a comprehensive guide to CFS, offering insights into its causes, symptoms, and effective treatments. With the right knowledge and support, there is hope for managing CFS and enhancing the quality of life for those affected by it. Let’s begin with understanding the disorder.

What is Chronic Fatigue Syndrome?

Chronic Fatigue Syndrome, also known as Myalgic Encephalomyelitis (ME), is a complex and debilitating disorder characterised by extreme fatigue that cannot be explained by any underlying medical condition. The fatigue worsens with physical or mental activity but does not improve with rest. CFS affects multiple systems in the body, leading to a range of symptoms that can vary in severity and duration.

What are the Causes and Risk Factors for Chronic Fatigue Syndrome?

While the exact cause of Chronic Fatigue Syndrome remains unknown, it is believed that a combination of factors may contribute to the development of the condition. These factors can vary from person to person and may include biological, genetic, and environmental influences. Here’s an overview:

Causes of Chronic Fatigue Syndrome

• Viral infections: Some individuals develop CFS following a viral infection, suggesting that certain viruses might trigger the condition. Possible viral triggers include Epstein-Barr virus (EBV), human herpesvirus 6 (HHV-6), and enteroviruses.
• Immune system dysfunction: Abnormalities in the immune system, such as chronic activation or dysregulation, may contribute to the development and persistence of CFS.
• Hormonal imbalances: Hormonal irregularities, particularly involving the hypothalamic-pituitary-adrenal (HPA) axis, have been observed in some individuals with CFS, indicating a potential link to the condition.
• Genetic predisposition: Genetic factors may make some individuals more susceptible to CFS. A family history of CFS or other related conditions can increase the risk.
• Stress: Physical or emotional stress, including traumatic events, may trigger or exacerbate the symptoms of CFS in some individuals.
• Environmental factors: Exposure to toxins, chemicals, or other environmental factors may play a role in the development of CFS.

Risk factors for Chronic Fatigue Syndrome

• Age: Though CFS can affect individuals of all ages, it is most commonly diagnosed in people between the ages of 40 and 60.
• Gender: More women than men are diagnosed with CFS, suggesting a potential hormonal or genetic component.
• Genetics: A family history of CFS or other related conditions, such as fibromyalgia, may increase the risk.
• Pre-existing health conditions: Individuals with certain pre-existing health conditions, such as autoimmune disorders, allergies, or depression, may be at higher risk.
• Lifestyle factors: High levels of stress, poor sleep habits, and lack of regular physical activity may contribute to the risk of developing CFS.

What are the Symptoms of Chronic Fatigue Syndrome?

Chronic Fatigue Syndrome is characterised by a wide range of symptoms that can vary in severity and duration. Here’s an overview:

Primary symptoms

• Severe, persistent fatigue: Lasting for six months or more, not relieved by rest, and significantly interfering with daily activities.
• Post-Exertional Malaise (PEM): A marked worsening of symptoms following physical or mental exertion, often delayed by 24-48 hours and lasting for days or weeks.

Other common symptoms

• Sleep disturbances: Unrefreshing sleep, insomnia, or other sleep disorders that do not provide adequate rest.
• Cognitive difficulties: Often referred to as "brain fog," these can include problems with memory, concentration, and information processing.
• Muscle and joint pain: Widespread muscle pain and joint aches without swelling or redness.
• Headaches: Frequent or severe headaches, which can differ in type and intensity.
• Sore throat: Recurring sore throat that may be chronic or episodic.
• Swollen lymph nodes: Tender or enlarged lymph nodes in the neck or armpits.
• Unexplained muscle weakness: Generalised weakness not attributed to any specific cause.
• Dizziness and orthostatic intolerance: Feeling lightheaded or dizzy, especially when moving from lying down or sitting to standing up.
• Flu-like symptoms: Sensations of feverishness, chills, or flu-like symptoms without an actual fever.
• Increase in sensitivities: Increased sensitivity to light, noise, or temperature changes.
• Digestive issues: Symptoms such as irritable bowel syndrome (IBS), including abdominal pain, bloating, and changes in bowel habits.
• Mental health issues: Increased anxiety, depression, or mood swings due to the chronic nature of the illness and its impact on quality of life.

Note: The aforementioned symptoms can fluctuate and have periods of remission and relapse, which makes CFS a particularly challenging condition to manage.

How is Chronic Fatigue Syndrome Diagnosed?

Diagnosing Chronic Fatigue Syndrome can be challenging as there is no definitive test and its symptoms often overlap with those of other conditions. The diagnosis is primarily based on a thorough evaluation of medical history, physical examination, and the exclusion of other potential causes of the symptoms. Here are the steps involved in diagnosing CFS:

• Medical history and symptom review: The diagnosis starts with a detailed discussion of the patient's medical history and a comprehensive review of symptoms, focused on the duration, severity, and impact of fatigue and other associated symptoms.
• Physical examination: A complete physical examination may be carried out to identify any physical signs that might suggest other underlying conditions.
• Laboratory tests: Blood tests, urine tests, and other relevant investigations to check for infections, hormonal imbalances, nutritional deficiencies, and other potential causes of fatigue.
• Testing for other conditions: Extensive laboratory tests and diagnostic evaluations to rule out other medical conditions that can cause similar symptoms, such as:

○ Thyroid disorders (e.g., hypothyroidism, hyperthyroidism)

○ Infections (e.g., Lyme disease, mononucleosis)

○ Autoimmune diseases (e.g., lupus, rheumatoid arthritis)

○ Mental health conditions (e.g., depression, anxiety)

○ Sleep disorders (e.g., sleep apnea)

○ Nutritional deficiencies (e.g., vitamin B12 deficiency, anaemia)

How is Chronic Fatigue Syndrome Treated?

Treating Chronic Fatigue Syndrome (CFS), also known as Myalgic Encephalomyelitis (ME), involves a multifaceted approach to manage symptoms and improve quality of life. Here are the primary treatment strategies:

Energy management

• Pacing: Learning to balance activity and rest to avoid overexertion. Patients are encouraged to recognize their limits and rest before reaching the point of exhaustion.
• Energy conservation: Techniques to minimise energy expenditure during daily activities, such as sitting while performing tasks or taking frequent breaks.
• Activity modification: Adjusting daily routines to prevent exacerbation of symptoms, focusing on prioritising essential activities.

Cognitive Behavioral Therapy (CBT)

• Symptom management: CBT helps patients develop coping strategies to manage the impact of CFS on their lives.
• Cognitive restructuring: Techniques to change negative thought patterns and behaviours that may contribute to symptom severity.
• Stress reduction: Methods to reduce stress and anxiety, which can exacerbate symptoms.

Exercise

• Graded Exercise Therapy (GET): A carefully-supervised and gradually-increasing exercise program tailored to the individual's capabilities. This approach aims to improve physical functioning without triggering post-exertional malaise.
• Flexibility and strengthening exercises: Gentle stretching and strengthening exercises to maintain muscle tone and flexibility.

Pharmacologic therapy

• Pain relief: Over-the-counter pain relievers (e.g., acetaminophen, ibuprofen) or prescription medications to manage muscle and joint pain.
• Sleep aids: Medications to improve sleep quality, such as low-dose antidepressants (e.g., amitriptyline) or sleep medications.
• Antidepressants: For those with significant depression or anxiety, antidepressants can help manage these symptoms.
• Immune modulators: In some cases, medications that modulate the immune system may be considered, although their efficacy varies.

Other nonpharmacologic treatments

• Diet and nutrition: A balanced diet rich in essential nutrients can help support overall health. Some patients benefit from dietary modifications, such as eliminating potential allergens or irritants.
• Hydration: Ensuring adequate fluid intake to prevent dehydration, which can worsen symptoms.
• Complementary therapies: Approaches such as acupuncture, massage therapy, or yoga may help alleviate symptoms and improve well-being.
• Psychological support: Counselling or support groups can provide emotional support and practical advice for managing the condition.
