User:Mr. Ibrahem/Chronic fatigue syndrome

Chronic fatigue syndrome (CFS), also called myalgic encephalomyelitis (ME), is a long-term condition that results in a decreased ability to do activities, tiredness worsened by activity, unrefreshing sleep, and cognitive problems. These symptoms are a worsening from before the onset; though may be variable over time. Pain is also often present. Symptom may be to such a degree that a person is unable to leave bed.

The cause is unclear; though a combination of factors is believed to be involved. Proposed mechanisms include infections, immune system changes, hormonal changes, metabolic changes, and genetics. Diagnosis is based on symptoms of greater than 3 or 6 months, that are not due to another condition.

There is no cure or specific treatment; efforts are aimed at improving symptoms. Pacing, also known as personal activity management, may help with worsening of symptoms after activity. Counseling may help with certain aspects of the condition. Graded exercise therapy is not recommended as of 2021. Those affected may have problems working, going to school, and being involved with social life. While some improve over time, others become disabled for an extended period.

Chronic fatigue syndrome affects about 0.9% of people. About 0.8 to 2.5 million people were estimated to be affected in the United States as of 2015. Those between the ages 40 and 60 years are most commonly affected; with women affected 1.5 to 4 times as often as men. It; however, can occur at other ages, including in up to 0.2% of child. The condition has been described since at least the 1930s. It was named "benign myalgic encephalomyelitis" is the 1950s while the term "chronic fatigue syndrome" was introduced in the 1980s. The two terms were than combined in 2003.
