Chronic fatigue syndrome (CFS), also known as myalgic encephalomyelitis (ME), is a debilitating condition that causes extreme fatigue and other symptoms, such as muscle pain, headaches, and cognitive difficulties. The exact cause of CFS is unknown, but it is believed to be related to a combination of genetic, environmental, and immune system factors.
There is no cure for CFS, but treatment can help manage symptoms and improve quality of life. This may include medication, cognitive behavioral therapy, and lifestyle changes.
