I am a 35 year old female whose blood pressure has hardly varied from 110-120 over 60-70, including during my 5th pregnancy. At a 5-week postpartum check, my blood pressure was 150 over 100 and has stayed in that range the 16 months since then (though brought down somewhat by medication after about 6 months).
CT scans have showed renal arteries to look normal, adrenal glands to look normal. Renin is low. Any ideas?
