[|Human|] My oxygen level dropped from 98 to 94 and I am concerned. I was diagnosed with AFib in 2011, but otherwise I am a very healthy, active 68 year old who drinks 1-2 glasses of wine/day, eats a very healthy diet and does aerobic ex. 3/week plus Pilates 1/week. Why did it go down? I do feel that I am not able to work out as hard as I used to a few years ago. My Doc said my lungs sound clear and my heart beat strong, but doesnt know why the drop.
[|AI|]  Hi, Welcome to Chat Doctor forum.  At this age, people will have a some atherosclerosis, and some alveolar closure and a degree of anemia.  I advise you to consult a chest physician for diagnosis and treatment.  Take more of green leafy vegetables, pulses,sprouts, and protein rich foods to have blood, general health and resistance against infections.  Wishing for a quick and complete recovery. Thank you.
