Can your SpO2 levels drop even if you don't have a fever? Like, is it possible for the levels to go down without experiencing a fever first? I'm curious about this because I don't have an oximeter to check.

Yes, SpO2 levels can drop in a 23-year-old male even without the presence of a fever.
Key points to understand:
- SpO2 (oxygen saturation) measures how much oxygen your blood is carrying as a percentage of the maximum it could carry.
- A drop in SpO2 can occur due to various reasons unrelated to fever: a. Respiratory issues like asthma or mild infections. b. Environmental factors such as high altitude or poor air quality. c. Temporary conditions like breath-holding or shallow breathing.
- Underlying health conditions like anemia, heart problems, or lung diseases can also cause lower oxygen levels without causing a fever.
If you notice consistently low SpO2 readings or symptoms like shortness of breath, dizziness, or chest discomfort, consult a healthcare professional for proper evaluation. Remember, a single low reading might not be concerning, but persistent or very low levels should be checked. Monitoring your symptoms alongside SpO2 readings helps provide a clearer picture of your health status.

So my dad had a normal eosinophil count back in July but then he got a fever and a dry cough. We used medicines and everything seemed normal afterward. But then a month later, he got a fever and cough again, and when we did a CBP test, it showed raised eosinophils. It's been a week now, and he doesn't have a cough or fever anymore, but the eosinophil count hasn't gone down. I'm wondering how we can bring these down. We used Delcar forte 250mg for 5 days. Do you think we should get another test done? Should I be worried about his eosinophil count not reducing? I compared the test report with the last one to see the difference. What would you suggest?

I'm really concerned about my sister who's been in treatment for pulmonary tuberculosis for a bit now. Her recent x-ray showed 45% damage on her right lung and 15% on the left one. These numbers worry me, and I'm unsure if this is a serious issue. The doctors mentioned lung cavities. Does this mean shes in a risky situation? Also, shes able to sit and walk but gets tired quickly when walking for too long. Shes only 20 years old. Is there any possibility that her lungs can heal and return to their original state? I'm wondering if the damage can be reversed since she's still young.
yes there are chances it can become normal. it takes sometime after completion of treatment
