It always does : It fluctuates in everyone; it has to to adjust to changes, such as gravity. If it didn't, you wouldn't be able to stand after lying down.

We messed up nature: Blood pressure always swings, but the body has some pretty clever ways of regulating that sort of thing. Blood pressure meds work by blocking 1 or more of the mechanisms the body has of raising blood pressure, so swings can be more pronounced.

Adjustment, time: Depends on how long you have been on this medication. You need to go back to dopctor for adjustment of dosage or even change to combination med.Furthermore your doctor can order blood test as well as x-ray to find out other cause of your blood pressure

It needs to adjust: If it didn't you would faint every time you stood up. It needs to adjust to gravity and temperature as well as other conditions.

blood pressure undergoes diurnal variation and follows your bodies natural circadian rhythm with fluctuations. It is normal for BP to drop at night, and isactually a good prognostic sign, compared to those patients who this does not happen.

BP Varies: It is normal for the blood pressure to fluctuate throughout the day. Being active, feeling stressed or having strong emotional thoughts, caffeine, salt intake, and many other factors can make the blood pressure rise. Resting or relaxing, sleeping, deep breathing or meditation can lower the blood pressure.

Why is my blood pressure fluctuating wildly?

It depends: It is normal for ones blood pressure to vary from moment to moment. Check your pressure each morning, sitting and standing, for 1 or 2 weeks. The major determinant of a significant change usually is the amount of salt one ingests (for example, the day after a salty meal, one expects a significant rise in blood pressure). If ones pressure is consistently greater than 125 systolic, see your dr.

What should someone do to bring blood pressure up?

Dr. Elden Rand
Cardiology 21 years experience
Many ways: Low blood pressure is generally desirable, but if there is lightheadedness with position change or other symptoms of low blood pressure, need to ensure no underlying problems- low thyroid, or low cortisol, or slow heart rate. Need to ensure good hydration status, consider liberalizing salt intake. Compression stockings can be quite helpful. Some medications may include midodrine or florinef (fludrocortisone).
