Answer 1

Mayo Clinic hypertension specialist Sheldon Sheps, M.D., and colleagues answer select questions from readers.
Answer
Caffeine is a mild stimulant found in coffee, tea, chocolate and many soft drinks. Too much caffeine can cause nervousness and jitters. It may also increase your blood pressure. The amount of caffeine in two to three cups of coffee can raise systolic pressure 3 to 14 millimeters of mercury (mm Hg) and diastolic pressure 4 to 13 mm Hg in people without high blood pressure.

It isn't clear how caffeine increases blood pressure. Some research has found that people who regularly drink caffeine have a higher average blood pressure than those who drink none. Other research has suggested that regular consumers of caffeine develop a tolerance to it — and as a result, caffeine doesn't have a long-term effect on their blood pressure.

In another twist, a 12-year study of 155,000 women found that drinking caffeinated cola may be associated with an increased risk of high blood pressure. However, the same causal relationship was not found with caffeinated coffee. In fact, the study suggested that women who drink caffeinated coffee may actually have a reduced risk of high blood pressure.

Among people who don't consume caffeine on a regular basis, caffeine can cause a temporary but sharp rise in blood pressure. Exactly what causes this spike in blood pressure is uncertain. Some researchers suggest that caffeine narrows blood vessels by blocking the effects of adenosine, a hormone that helps keep them widened. Caffeine may also stimulate the adrenal gland to release more cortisol and adrenaline, which cause your blood pressure to increase.

As a precaution, some doctors recommend limiting caffeine to 200 milligrams a day — about the same amount as in two 12-ounce cups of brewed coffee. Keep in mind that the amount of caffeine in coffee and soft drinks varies by brand. Also, avoid caffeine right before activities that naturally increase your blood pressure, such as exercise, weightlifting or hard physical labor.

Answer 2

The caffeine in the tea or coffee is what affects the blood pressure. To limit the side effects of caffeine withdrawal, wean yourself to decaffinated products.

If you are unsure about this, talk to your medical professional. Many things affect blood pressure. If 146-147 is your top number, that is not considered high.

There are many websites that address diet issues with regard to blood pressure and other heart related issues. Do a search, and look around for options.

There's good news and bad news for java junkies. Modest coffee drinking is associated with a small increase in blood pressure, Johns Hopkins investigators say, but it's probably not enough to substantially increase your risk of hypertension. In a long-term study of more than 1,000 men, drinking a daily cup of regular coffee raised systolic pressure (the upper number) by 0.19 mmHg and diastolic blood pressure (the lower number) by 0.27 mmHg. Coffee drinkers also had a greater incidence of hypertension (28 percent) than their non-coffee drinking counterparts (19 percent).

Answer 4

yes - coffee moreso than tea due to the greater caffeine content. caffeine is a stimulant and can cause the heart to beat faster (in excess it can cause palpitations) so this may increase the blood pressure. I would recommend the caffeine free stuff - i believe that the caffeine free tetley is nice and as i don't like coffee my mother in law can vouch that the nescafe gold blend decaff is nice.
alternatively you could try some herbal teas such as peppermint or nettle. maybe not the dandelion coffee - it's yeuk!!

Answer 5

Drinking caffeinated tea or coffee can raise the blood pressure. My doctor told me so. It is best, if you drink a lot of either, to drink decaf.

Answer 6

It can because caffine is a stimulant which will increase your heart rate which in turn may affect your blood pressure. But it should be ok in moderation. You're pressure isn't that high.

Answer 7

Coffee does. Tea doesn't.

Answer 8

yes caffeine is a vasoconstrictor, ( constricts your blood vessels), thus raising your bp.

Answer 9

if it has caffene it will stimulate you, so probably yes.
