Are lower SpO2 and fast heart rate asthma symptoms?

Posted by @ling @wangling, Apr 14 7:06pm

Hi everyone,
Last spring, I experienced lower spo2 " 90-92", and a fast heart beat 100-105. And after I took Wixela for two weeks these symptoms were gone. I could walk up to the mountain, with no problems.
But now these symptoms are back. I have taken wixela for about a month now, I still have the symptoms.
My question: Are these symptoms related to asthma? I didn't have asthma in my life, but my pulmonologist said that I may have adult onset eosinophilic asthma. But my eosinophilic level went up twice only when I had a lung infection. So to me, based on my experiene, I am still in muddled waters, not sure what I have. Your experience will be greatly appreciated.
Thanks,
Ling

Scoop, you’re correct. I was replying to you. The first pulmonologist made the methacholine challenge sound like the definitive test and that had been my impression. It makes sense that steroids would impact results (and I like things to make sense). Thanks for replying.

I was given a histamine provocation test 10-15 years ago which apparently proved I had asthma although I have been pretty much unaware of it. I occasionally have a dry cough, react to cold air etc...but most of my coughing is I believe Bx related.
