How long have you been on blood pressure medication? Sometimes it takes a while for physicians to adjust your dose to see the result they are looking for. Sometimes people may respond to one med and not another. It may take trial and error to determine the right med for you.
You did not mention your age. Sometimes higher blood pressures can result the older you get, although not necessarily so.
Do you consume stimulants, like caffeine or methamphetamines or diets substances that contain stiumlants? Those substances can spike blood pressure. Some people are more sensitive to stimulants than others, so your friends may be able to use them and not have problems but you may be more sensitive.
Maybe your condition is more genetic--do your parents have high blood pressure? Are you pregnant?
Make sure your doctor tests your
kidney function. Kidneys help regulate blood pressure.
Sometimes people have conditions, which can cause them to secrete substances like epinephrine--sometimes called
adrenaline, in excessive amounts. Excessive amounts of epinephrine can cause a big spike in your blood pressure. I suggest requesting a urine test the can help measure the amount of 'metanephrines' in your system.
Metanephrines are the metabolized by products of catecholamines.
Norepinephrine and epinephrine are types of catecholamines. If you have a high level of metanephrines, you may have an increased amount of catcholamines in your system.
Epinephrine helps with your 'flight or fight' response--so they are normal to have in your body. For example, they help your heart pump faster, open the passages of your lungs so that you can be prepared to 'run' or handle
stress.
In excessive levels, they can affect your health.
The result should help your doctor to determine if more tests are needed to diagnose this condition. This condition is treatable, by the way. It is important to rule it out as a cause of your
hypertension.
High blood pressure is a condition that you should take seriously. Continue your healthy life style--exercise, good diet, dealing with stress. Good luck!
