Why does my bp peak in late afternoon after being normal all day.

BP: BP is hard to treat in some individuals and there may be no rhyme or reason why is fluctuates. If your noon time meal is high in sodium that could account for it, or hormonal changes throughout the day could too. you may need one of your BP meds to be changed to a twice daily regimen to gain better control. Ambulatory monitoring helps the Dr. treat you best, so f/u with dr and show your #'s.

Unclear: You take a lot of blood pressure meds. This probably means you have difficult to control bp. Most times the peak of blood pressure is actually very early in the AM. Have you done ambulatory blood pressure monitoring. This checks for all of 24 hours. Is your regimen spaced out through the day or do you take all meds in the AM. Actually need closer follow-up by your docttor

Blood pressure: BP varies during the course of the day. One eats 10-12 grams of salt during the day which can cause increase in blood pressure. Also because of stresses during the day, the bursts of adrenal can also cause elevated BP

That may be: Your pattern and have something to do with when you take your meds. Blood pressure naturally peaks between 2AM and 6 AM
