What causes high blood pressure spikes?

What causes high blood pressure spikes?

Diet: Hbp rises due to eating a diet full of salt and water. People with hbp have difficulty excreting excess salt and water. If a person with hbp eats a diet filled with salt (hamburgers or steaks) and fluids (excessive coke or beer), then they will see a spike in their blood pressure because they can't get ride of this extra salt and fluid normally. Not taking your meds will lead BP spikes as well. ...Read more

Hypertension (Definition)

A blood pressure reading has two numbers: a systolic blood pressure and a diastolic blood pressure. The systolic blood pressure is the maximum pressure the blood exerts on the vessels when the heart is beating. The diastolic blood pressure is the pressure the blood exerts on the vessels in between heartbeats. Hypertension, or high blood pressure, begins when the systolic blood pressure remains above 140 or when the diastolic blood pressure remains above 90. Hypertension can be a result of increased blood flow through vessels or increased resistance to ...Read more

Does baroreflex failure always cause high blood pressure spikes? Whats the main symptoms?

Does baroreflex failure always cause high blood pressure spikes? Whats the main symptoms?

No it does not: Baroreflex or Baroreceptor reflex is one of the body's homeostatic mechanism that helps to maintain Blood Pressure at nearly constant level It provide negative feedback when BP goes up for some reason and it reflexively causes the heart rate to decrease'And if BPdecreases it does the reverse and thereby maintain aconstant Blood Pressuse . But it does not cause high blood pressure spikes ...Read more

I've been waking up at night with high blood pressure spikes, feeling extremely lightheaded and horrible. I'm okay during the day. What causes this?

Circadian rhythm: Is the normal (about 24 hours) rhythm of the brain that is controlled by the night/day cycle. During part of each 90 minute sleep cycle we have about 10 minutes of rem or active sleep when the autonomic nervous system (ans)(automatic) becomes active. Your ANS activity is exaggerated and unbalanced and the commonest cause is poor diet, especially all that sugar and sweeteners if it applies to you. ...Read more

On high blood pressure, are there other foods that can cause blood pressure spikes like starches or grains?

Salt: Salt does cause fluid retention and therefore increases blood pressure. Very low blood sugar can cause release of adrenaline which raises blood pressure, other than that, I do not know of any interaction with particular foods. ...Read more

Does significant labile or episodic hypertension in which blood pressure spikes in response to relatively minor stresses pose health risks?

Yes: The risks of HTN are multiple and can lead to headaches, cardiovascular disease(including heart attacks), stroke, and so on. The best course of treatment is periodic blood pressure checks by your primary care physician! there is an entity called white coat hypertension but that diagnosis should come from a physician (or the associated nurse practitioner or physician assistant). ...Read more

When I go to the doctor, my otherwise normal blood pressure spikes high. What can I do to lower it at the doc?

When I go to the doctor, my otherwise normal blood pressure spikes high. What can I do to lower it at the doc?

High Blood pressure: High blood pressure is an abnormal response to stress. So it's not normal to have a high BP at the doc. The body doesn't care what type of stress...Emotional, fatigue, alcohol, pain etc. Early on BP will be normal at home, while sleeping etc. But gradually it will go up and be high most of the time. The "white coat" excuse is way overused and rarely a diagnosis. Most just have high bp. ...Read more

High Blood Pressure (Hypertension) (Definition)

A blood pressure reading has two numbers: a systolic blood pressure (top number) and a diastolic blood pressure (bottom number). The systolic blood pressure is the pressure the blood exerts on the artery when the heart is at maximum contraction. The diastolic blood pressure is the pressure the blood exerts on the artery when the heart is at maximum relaxation. Ideal blood pressure is 120/80 or lower. High blood pressure, or hypertension, is 140/90 or higher. ...Read more

Blood Pressure (Definition)

Blood pressure is a measurement of the force placed on the blood vessels and is comprised of the "systolic" pressure (the top number on a blood pressure meter) which is the peak pressure when the heart is pumping, and the "diastolic" pressure (the bottom number on a blood pressure meter) which is the pressure during the resting phase ...Read more
