Do allergies cause chronic fatigue syndrome?
Allergies per se do not produce fatigue. If you have strong allergic reactions (i.e., sneezing, itchy eyes, and/or wheezing), you might feel fatigued. However, you do not become fatigued from allergies alone – only from the degree of symptoms they produce. It is worth noting, however, that in one study, people with chronic fatigue syndrome had a higher incidence of allergy than the population as a whole. Whether or not this has any significance is not known.
