Can seasonal allergies cause fatigue?

Can allergies make you tired? I always get the stuffy nose and itchy eyes but this year I feel really tired too. Could that be from the allergies or is it probably having to do with something else?

Answer

Seasonal allergies can be very unpleasant and lead to a host of uncomfortable symptoms, including the stuff nose and itchy and watery eyes that you describe. The constellation of sinus and nasal congestion, often with sneezing and other systemic symptoms, can definitely disrupt your sleep. Even if you don't remember waking up in the middle of the night, you may be sleeping less soundly and with more night restlessness than is normal. This can have a profound effect on your day to day energy levels and cause significant amounts of fatigue. However, it is also possible that you have a second medical issue going on, as there are many different diagnoses that can cause fatigue. In your case, the best thing to do is to see your primary care provider right away. He or she can take a thorough history and ask about any other symptoms you may or may not have noticed recently. A physical exam can also help reveal findings that may suggest whether you are simply suffering from allergy-related fatigue or from something else. Finally, some basic lab tests can rule in or out some common causes of fatigue, including anemia, altered thyroid function, or infection. Hopefully you will be feeling better soon--and if no other cause is identified, your primary care physician can also help prescribe some medications to help treat your allergy symptoms.
