low oxygen levels

[joanie30]

Hi, I'm a 30 year girl withlow oxygen levels.  About 2 months ago I started to feel our of breath anytime I did anything.  Went to my consultant who has found that I desaturate to 82% by just walking the corridor.  I have had every test done and everything is normal.  I am wondering does anybody have this problem as they cannot come up with a conclusion.

They have done most of the tests on the heart and lungs i.e. echo, ct scans, xrays and even a angiogram and all coming back normal.  They don't have me on anything and can't  give me an answer. I'm so frustrated at this stage and worried

Did they do tests on your heart? Also, what tests did they do...(such as lung function tests, echocardiogram, CT scan and xrays etc...). Sometimes heart conditions cause low O2 levels if the lungs check out fine. Pulmonary hypertension and shunting are some examples of disorders that often drop your O2 levels.
I hope you find answers soon...do the docs have you on O2 while walking? I hope so with those numbers.
