Peak flow better in mornings

Hi

My PF tend to be higher in the mornings than evenings, although I've read that in asthma you get a morning dip. Is this something that can happen with asthma or (clutching at straws here) could it indicate that it is not asthma?

I measure mine around 7-8am and 10-11pm and they're usually around the same (450 vs 490) however I have symptoms and lower PF during the day (400-430). Don't know what it means though I'm afraid! Hope you find and answer, I'd be interested too!

i think its individual and just cos yours doesnt fall in the morning doesnt mean that you dont have asthma especially if you have been diagnosed by having the breathing tests etc. my peak flow is often lower in the morning and even lower late at night but raises through the day.

Hi,

my peak flows are all over the place but they tend to be higher in the morning and drop frighteningly during the day (upto 170l/min). Usually due to my lungs reacting to all the pollutants while i'm out working. Some peoples peak flow are the otherway round it depends whats normal for you. Keep a regular record of your peak flows for a couple weeks or so and you will probably see a pattern. Also try orderering the leaflets as they have lots of useful info, or you could ring the asthma helpline they are really helpful and can give v good advice.

not sure you'll ever find an answer, mine is all over the place as well, some days I can have a really high morning reading then in the evening upto 20% lower, yet a day later the total opposite, no pattern and no reason for it.

My peak flows are all over the place regardless of morning or night time. I just really use them as i rough guide as to what my asthma is doing but i cant always rely on it. My best peak flow is 330 yet i can still end up being admitted to hospital with my version of a normal peak flow. So try not to let it worry you too much. xx

Hi - thanks for all the replies. This forum is great for getting ""real-life"" information about asthma. All the information you read on the web or in books tends just to describe ""the average"". Take care. RS
