Does Coffee Cause High Blood Pressure
The relationship between high
blood pressure and coffee is a very controversial and a debated issue. Some studies suggest that
coffee is responsible for high blood pressure, whereas another school of thought holds opposite
views. Medical research shows inconsistent results in this regard and this may be one of the
reasons that the debate behind this critical issue still carries on.
Caffeine is a potent brain stimulant
One thing is sure that coffee
contains high caffeine content than the amount found in tea, chocolates and soft drinks.
Caffeine is a potent brain stimulant and is responsible for nervousness palpitations and
increase blood pressure. Studies show that When we take coffee in moderate amount, lets say
(about 250 mg a day), which is equal to 2-3 cups of coffee, it dose not prove to be harmful.
Anything above 2 to 3 cups of coffee may be a matter of concern for your BP. Baseline BP is very
important, e.g those with high BP values would likely experience a greater increase than those
with normal BP from the same cup of coffee.
Tolerance for caffeine develops
if we use coffee regularly so BP may not be raised by regular use of coffee. Studies show that
coffee by itself is not responsible for high blood pressure in an individual. Other factors,
such as sex, smoking, educational level, exercise, environment, body weight, your work style,
total intake of calories, alcohol consumption, occupation, family history and many other factors
have to be considered.
Now come to non-regular
drinkers of coffee, they are probably at a higher risk, as the caffeine in the coffee causes
abrupt increase in blood pressure. However, this rise in BP is transitory, and after two to
three hours of drinking a cup of coffee the blood pressure become normal. You may have many
long-term health implications by these temporary effects of caffeine on the body's blood
According to new research
reported in The American Journal of Epidemiology in 1999 strongly indicates that consumption of
caffeine does not contribute to Cardiovascular disease even for those drinking more than four to
six cups of coffee a day
If you want to be on safe side,
keep your caffeine intake as low as 200 milligrams a day. If you are a coffee lover and also
have a feeling that it might raise your blood pressure, you may drink decaf. Have regular
exercise, Follow DASH diet program strictly and try to keep free of undue
I often advise my hypertensive
patients to reduce intake of Coffee to moderate level of two cups daily. Try to avoid
caffeinated beverages (coke, coffee, tea) at least two hours prior to bed.
