Fatigue Syndrome refers to a group of medical conditions that are characterized by extreme and ongoing tiredness or exhaustion. This condition can be caused by various factors such as stress, lack of sleep, poor nutrition, infection, or an underlying medical problem. Fatigue syndromes include Chronic Fatigue Syndrome (CFS), Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), and fibromyalgia. These conditions can significantly impact a person's quality of life, making it difficult to carry out daily activities or work. Treatment for fatigue syndromes may involve lifestyle changes such as improving sleep habits, managing stress, and increasing physical activity levels, along with medication or therapy if necessary.
