What is the impact of caffeinated coffee on blood pressure?

A recent study by Tahira Khurram, Samina Khanum, Asma Nadeem, Usama Kiran, Rashida Kazmi, and Ummara Rasheed in the The Medical Journal of Malaysia sheds light on this important question.

What was the study?

The study involved 85 healthy, non-hypertensive individuals aged 18-28 years including both males and females.

Blood pressure (BP) was measured using an automatic digital blood pressure monitor before and at 30, 60, and 90 minutes after consuming coffee.

Each participant consumed 100 mL of coffee prepared from 50 mg of caffeinated coffee within 4 minutes.

What were the results?

The study found significant differences in both systolic blood pressure (SBP) and diastolic blood pressure (DBP) after the intake of caffeinated coffee.

There was an increase of 4.4 mmHg in Systolic Blood Pressure after 60 minutes and 5.02 mmHg after 90 minutes from the baseline. Indeed, similar significant changes were noted in Diastolic Blood Pressure.

The study also highlighted that individual responses to caffeine varied - with some participants being more sensitive to caffeine's effects on blood pressure.

How does caffeinated coffee affect blood pressure?

The findings of this study have several important implications for coffee consumers, particularly those concerned about their blood pressure.

While caffeinated coffee can cause a noticeable increase in both systolic and diastolic blood pressure, individual responses vary.

Individuals who regularly consume caffeinated coffee should monitor their blood pressure, especially if they have a history of hypertension or are sensitive to caffeine.

Awareness of personal caffeine sensitivity is crucial and people who experience significant increases in blood pressure after consuming caffeinated coffee might consider reducing their intake or switching to decaffeinated coffee.

Decaffeinated coffee offers a viable alternative for those who enjoy the taste of coffee, but need to manage their blood pressure.
