Put Down the Coffee Before Your BP Test
Each year, Americans spend almost $40 billion dollars on coffee. Extensive research has been conducted to learn about the potential health effects—good and bad—of drinking coffee. Studies have shown, for example, that caffeine in coffee increases blood pressure.
Now, a new study published in the American Journal of Hypertension shows that coffee’s effect on blood pressure is stronger in people who only drink an occasional cup than in regular coffee drinkers, suggesting it’s possible to develop a tolerance to the drug. The study also showed that, in people who take medication to lower blood pressure, drinking coffee reduces the effects of the medicine.
According to researchers, drinking coffee within two days of blood pressure testing may interfere with high blood pressure diagnosis and treatment. More research is needed to determine how coffee affects blood pressure management.
