I'm a 28-year-old woman who works out regularly. My mom has a pulse oximeter at home and I decided to use it just for fun. When I was resting, my blood oxygen level was 99, but after a short run on the treadmill it went down to 86. My heart rate was only around 130. Usually, I work out a lot more intensely than I did during this test. I'm worried that I might unknowingly be harming my body. Do you think I should get this checked? If so, what kind of doctor would be best for evaluating this situation?

It's understandable to be concerned, but a drop in oxygen saturation during exercise, especially at high intensity, can happen, particularly if you're pushing your limits. I recommend seeing a pulmonologist or a cardiologist to evaluate your lung and heart function. They can conduct tests like a stress test or pulmonary function test to assess your oxygen levels and overall health during exertion.

I'm really worried about my dad. He had COVID recently and now the doctor mentioned that he has some kind of fistula in his left lung. I'm not sure what this means for his recovery or his health in general. Could you explain what a fistula in the lung is and how serious it might be? Is it something that happens because of COVID infections, and what kind of treatment should he expect?

I'm often catching colds and having a cough with the changing weather. I've got allergies to dust and asthma runs in the familymy mom and grandma have it too. I'm thinking of sticking to Ayurvedic medicine because I'm worried about the long-term use of allopathic stuff. But this time, I noticed some blood in the phlegm when I blew my nose. Should I be concerned about this, or is it alright to keep using Ayurveda?
