Chronic fatigue, also known as myalgic encephalomyelitis (ME) or systemic exertion intolerance disease (SEID), is a complex and serious long-term illness characterized by extreme and persistent fatigue that is not improved by rest. The fatigue is often worsened by physical or mental activity and other symptoms like muscle pain, headaches, poor sleep, and difficulty thinking clearly.
Diagnosing chronic fatigue can be challenging as there are no definitive medical tests for it. Doctors typically make a diagnosis based on a thorough clinical evaluation ruling out other possible causes. Possible causes and risk factors are not fully understood but may include viral infections, immune system dysfunction, stress, and genetics.
Some key facts about chronic fatigue:
Living with chronic fatigue can be extremely difficult. Even basic physical and mental activities may be limited or impossible on bad days. Patients report struggling with:
Over time, pushing oneself too hard can make symptoms become permanently worse. That's why pacing and balancing rest and activity is critical. Along with lifestyle changes, many patients find relief from medications or supplements that help manage energy levels, sleep, pain and other issues.
Depression and anxiety frequently occur with chronic fatigue. Experiencing disabling fatigue, pain and "brain fog" for months or years takes a huge emotional toll. There can be grief over lost jobs, social isolation and strained family relationships on top of coping with the profound physical limitations. Professional counseling or support groups can help greatly.
In summary, chronic fatigue syndrome is a complex disorder marked by incapacitating fatigue and a range of symptoms making daily living extremely challenging. Researchers are working to better understand the biological causes and most effective treatments. With a careful pace and symptom management, many do see gradual improvements in functioning over time. Continued advocacy and funding is still urgently needed for this neglected yet devastating disease.
