False Positive Aldosterone to Renin Ratio due to beta blocker?

[Guest guest]

The new endocrinologist I am seeing did not seem to think my aldosterone to

renin ratio was out of line. She explained that Bystolic (beta blocker)

suppresses renin and therefore caused my ratio to be high.

I posted previously that my ratio was 50. The aldosterone was 14 and the renin

was 0.28. She told me that since aldosterone was not high, PA was not a

concern. I had a clear CT scan showing no mass and normal adrenals. She tested

me for a pheo using 24 hour urine, but did not order any further testing

regarding the PA. I should get the 24 hour urine results sometime tomorrow.

Is she correct that Bystolic can suppress renin by a significant amount?

She also mentioned that surgery would not be recommended due to a mass not

showing up on the CT. Therefore, she thought that a confirmatory test for PA

was unnecessary and told me she would treat with medicine unless my BP would get

out of control.

I thought surgery would be the best option as it might cure blood pressure and

the low potassium drops.

Anyone have any thoughts on this Endocrinologist? Is it important for me to

seek out additional testing regarding the PA?
