11 Medical Conditions That Mimic Anxiety (But Aren’t What You Think)

5. Chronic Fatigue Syndrome: The Exhaustion Enigma

Chronic Fatigue Syndrome (CFS), also known as Myalgic Encephalomyelitis (ME), is a complex disorder characterized by extreme fatigue that cannot be explained by any underlying medical condition. This persistent fatigue can lead to symptoms such as difficulty concentrating, memory problems, and unrefreshing sleep—all of which can be mistaken for anxiety. The connection between CFS and anxiety is multifaceted. The constant state of exhaustion can lead to feelings of frustration and hopelessness, which can contribute to the development of anxiety. Additionally, the cognitive difficulties associated with CFS can lead to a sense of overwhelm and difficulty managing daily tasks, further exacerbating feelings of anxiety. Diagnosing CFS involves ruling out other potential causes of fatigue and conducting a thorough evaluation of symptoms. Treatment typically focuses on managing symptoms, such as improving sleep quality and addressing pain or depression. By addressing the underlying fatigue, individuals often experience a reduction in anxiety-like symptoms and an improvement in quality of life.
