Chronic Fatigue Syndrome


Chronic fatigue syndrome (CFS) is a chronic condition that causes unexplained, extreme fatigue.Unlike regular tiredness, the fatigue caused by CFS does not get better with rest and can interfere with daily life. The cause of CFS is unknown, so there is no guaranteed way to treat it. Treatment typically focuses on managing symptoms and daily activities with therapy and lifestyle changes.

Symptoms and Diagnosis

The primary symptom of CFS is severe fatigue that does not improve with rest and lasts longer than 6 months. People with CFS may also have headaches, muscle pain, recurring sore throat, memory problems, trouble concentrating, swollen lymph nodes in the neck or armpit, and insomnia. Mental and physical exercise can worsen fatigue in people with CFS. Patients also report other conditions that occur alongside fatigue, including irritable bowel, allergies, and dizziness or fainting. If not addressed, CFS can lead to depression, decreased productivity, and social isolation.

Diagnosing CFS requires ruling out any other possible causes of fatigue, including sleep disorders, mental health conditions, and medical conditions such as anemia and underactive thyroid. Doctors will take a detailed medical history and perform physical and mental health exams to exclude other health conditions. A diagnosis of CFS requires that a person have unexplained fatigue that lasts for 6 months or more, does not get better with rest, and significantly disrupts daily life, along with several physical symptoms.
