How does the excretory system work to lower blood pressure ?

Dr. James Marx answered

Specializes in Pain Management

Complex: The kidneys are critical from a number of factors. They eliminate excess water from the circulatory system which keeps pressure from rising in the system. They also produce a number of chemicals like renin and angiotensin which constrict blood vessels which if out of balance can cause high bp.

Currently on Valsartan 40mg. My blood pressure usually goes up to 160/100 when I'm anxious, but is 110-118/64-74 when relaxed. Can I increase the dose to 160mg or 320mg to lower the maximum bp or does it only work on baseline bp at rest?

A member asked:

Very good morning doctors. I was told Losartan HCTZ can raise both serum creatinine & BUN and lower eGFR. I take Losartan HCTZ and it seems to work great. How do I resolve this if I need a water pill diuretic to help control blood pressure?
