My mother (65) suffered recently from lung infection, later through diagnosis it revealed that she had copd. This is the first time ever she suffered and revealed that she had lung issues. She got hospitalized 2 times for that, she is ok for now with medications and inhaler but the thing is her nt pro bnp test shows around 3000- 4000. The dr prescribed meds like Planep 25 and Ecosprin AV 75 that she's taking for a few months. At the time when she suffered lung infection and was hospitalized, it increased around 20k which is now declined for sure. But still it's not getting in a normal range. She also have thyroid and takes medicine for a long time. So any suggestions would be very helpful on how to recover it.
