Fatigue is a big problem for most people allergies<\/a>.<\/p>\n Fatigue<\/a> is certainly a common allergy symptom<\/a>, and there are at least two reasons for this that I know of.<\/p>\n The first<\/strong> is that an allergic reaction<\/strong> is like being sick<\/em>. Normally, we become sick when we have an infection. The body fights it off, which takes lots of energy. Result: you get tired.<\/p>\n An allergy<\/strong> is the body mistakenly<\/em> thinking that an ordinary substance<\/em> such as a wheat<\/a> protein or gluten<\/a>, is an infection. The body is wrong, but it treats the substance in the same way as an infection. Result: you get tired, just like having the flu or a cold.<\/p>\n The other reason<\/strong>, and I know this happens in my case, is that allergies<\/strong> can affect your sleep<\/strong>. If you can’t sleep properly, you will feel a bit tired the first day, more the next, and eventually<\/em> you will become chronically fatigued<\/em>. Add this to the tiring effects of the body fighting the substance you are allergic to, and its not surprising that you get so tired.<\/p>\n
