Chronic fatigue syndrome (CFS) is a debilitating and often misunderstood condition. While there is no one-size-fits-all answer to CFS, there are a number of factors that can contribute to the condition, including allergies.

Allergies are one of the most common causes of CFS. According to the CFS Association, up to 75% of people with CFS have allergies. This is likely due to the fact that CFS is a condition that is often associated with environmental factors, such as pollution and allergens.

Allergies can cause a number of symptoms in people with CFS, including fatigue, headaches, and difficulty breathing. In some cases, allergies can be so severe that they lead to a condition called asthma.

If you are struggling with CFS and have allergies, it is important to talk to your doctor. He or she can help you determine which allergens are causing your symptoms and recommend treatments.
