What is the maximum daily amount of coffee for hypertensive patients?

The German Heart Foundation said that patients with high blood pressure can drink coffee in moderation, explaining that the maximum daily amount is 400 milligrams of caffeine, which is equivalent to 4 to 5 cups of coffee.

The Foundation added that blood pressure should be measured 30 minutes before drinking coffee or after drinking it, to ensure that the measurement values are not affected by coffee consumption, knowing that the ideal values for blood pressure are 120/80 mm Hg.

Should people with high blood pressure avoid coffee?

A 2017 research review concluded that people with high blood pressure should exercise some caution when drinking coffee, but do not need to avoid it, according to a report in MedicalNewsToday.

The review found that while there were older reports of a link between coffee drinking and high blood pressure, more recent studies suggested that 3 to 4 cups a day either had a neutral or beneficial effect.

A 2016 study of 40 healthy, regular coffee drinkers found that all types of coffee increased blood pressure, but levels remained within healthy levels.

The increase in blood pressure was temporary but still measurable 3 hours after drinking coffee.

coffee quantity

Some research suggests that the amount of coffee a person drinks determines its effect on blood pressure.

A 2015 study reported an increase in systolic blood pressure only in people who did not drink coffee frequently.

Another research review found that typical coffee consumption of more than 3 cups per day does not increase the risk of developing high blood pressure.

However, there was a slightly elevated risk associated with 1 to 3 cups a day.

Does decaffeinated coffee raise blood pressure?

Since coffee contains many different compounds other than caffeine, other compounds may be responsible for its effect on blood pressure.

However, anyone can try switching to decaffeinated coffee to see if their blood pressure drops.

How does caffeine affect blood pressure?

Caffeine can cause your blood pressure to rise briefly but significantly, even if you don't have high blood pressure, said Dr. Francisco Lopez Jimenez of the Mayo Clinic.

It's not clear what causes this rise in blood pressure, and the response of blood pressure to caffeine varies from person to person.

Some researchers believe caffeine can block a hormone that helps keep arteries wide.

Others believe that caffeine causes the adrenal glands to release more adrenaline, which leads to high blood pressure.

Dr. Jimenez adds that some people who regularly drink caffeinated beverages have higher average blood pressure than those who don't.

Others who regularly drink caffeinated beverages develop a tolerance to caffeine.

As a result, caffeine does not have a long-term effect on their blood pressure.

If you have high blood pressure, ask your doctor whether you should limit or stop drinking caffeinated beverages.

Avoid caffeine right before activities that naturally raise blood pressure

The U.S. Food and Drug Administration says 400 milligrams of caffeine per day is generally safe for most people.

However, if you're concerned about caffeine's effect on your blood pressure, try limiting the amount of caffeine you drink to 200 milligrams a day, which is roughly the amount generally taken in two cups of coffee, each cup containing 237 milliliters.

Keep in mind that the amount of caffeine in coffee, energy drinks, and other beverages varies by brand and method of preparation.

Dr. Jimenez also advised people with high blood pressure to avoid caffeine right before activities that naturally raise blood pressure, such as exercise, weightlifting or strenuous physical work.
