Just Tired – or Chronic Fatigue Syndrome?

Chronic fatigue syndrome (CFS) is considered to be a complicated disorder because the cause is unknown, and there's no one particular test to confirm a diagnosis.

CFS is characterized by extreme tiredness, yet an afternoon nap or an earlier bedtime won't change that. In addition to the fatigue, which lasts for at least six months, a wide range of other symptoms can include:

• Tender lymph nodes in the neck or armpits

• A sore throat that occurs repeatedly

• Digestive issues, like irritable bowel syndrome

• Chills and night sweats

• Allergies and sensitivities to foods, odors, chemicals, light, or noise

• Shortness of breath

• Irregular heartbeat

• Problems with memory or thinking skills

• Dizziness that worsens with moving from lying down or sitting to standing positions

• Unrefreshing sleep

The cause is unknown, and might be triggered by a number of factors, such as:

• Genetics – CFS appears to run in some families

• Infections – Some people develop symptoms after getting better from a viral or bacterial infection

• Physical or emotional trauma – Some report that they experienced an injury, surgery, or significant emotional stress shortly before their symptoms began

Because of the range of symptoms, a variety of medical tests may be needed to rule out other health problems that have similar indicators. There is currently no cure for CFS, and treatment for the condition focuses on easing symptoms.
