Can peak flow readings be low because of nasal congestion?

[happy4health]

Can nasal congestion cause a different reading on your peak flow meter? I ask this because since Friday I have been using my Flonase on a regular basis, and I've noticed some improvemnt already. Well today I took a peakFlow reading(s) and it was at 500(regularly a good reading for me is450) I haven't had any asthma symtoms so there is no need to take my prevental inhaler. I do get chronic sinus infections, and more often then not I'm congested. Though I have to wonder if the congestion I was having (before the Flonase) could have lowered my peak flow readings in the past. I could just kick myself, if that were/is the case. I could have felt better all this time,

Absolutely. The congestion can get into your lungs and cause inflammation, resulting in poor peak flow. I'm glad you are getting such great improvement with just flonase. I take quite a few meds just to stay in the yellow range sometimes.

You absolutely right. I have found that post nasal drip is usually what irritates the throat and lungs.

One of my thoughts was allergies playing a role in your asthma being exacerbated. I know nasal congestion can be d/t allergies. For me, my pf drops when I get nasal congestion, but I know the congestion is a result of allergies (pollens, dust mites) and d/t the allergy my asthma is exacerbated too.

Isn't nasal congestion a form of asthma anyway? Whatever allergens cause your asthma usually cause nasal congestion too right? Unless u solely have EIA and no allergies.
