If you’ve received a diagnosis of high blood pressure, you might scrutinize every morsel, concerned it could worsen your condition. While dietary adjustments are often discussed wiht healthcare providers, questions about coffee’s impact are common. Can coffee elevate blood pressure,or is it a non-issue?

Turns out,coffee can temporarily affect blood pressure,but this effect can diminish with regular consumption.

Hypertension,or high blood pressure,occurs when blood flow against blood vessel walls is consistently too high,according to the American Heart Association (AHA). Blood pressure readings consist of two numbers: systolic (top), measuring arterial pressure during heartbeats, and diastolic (bottom), measuring pressure between beats. A normal reading is below 120/80, while hypertension is 130-139/80-89 or higher, says the AHA.

If you have hypertension or are seeking ways to lower blood pressure naturally, coffee might be a concern, says Cheng-Han Chen, MD, a board-certified interventional cardiologist and medical director of the Structural Heart Programme at MemorialCare Saddleback Medical Center. Though, individual responses vary.Here’s what to consider regarding coffee and hypertension.

Does Coffee Raise Blood Pressure?

It’s possible. However, caffeine’s effect on blood pressure isn’t guaranteed.”Everyone responds differently to caffeine,” notes jessica Cording, R.D., author of The Little book of Game-Changers.

Some studies suggest coffee can cause blood pressure spikes. One study in the journal Nutrients found that coffee consumption was associated with a temporary increase in blood pressure. However, other research indicates that regular coffee drinkers may develop a tolerance to these effects.

“everyone responds differently to caffeine.”

According to ragavendra Baliga, M.D.,M.B.B.S, a cardiologist at The Ohio state University Wexner Medical Center, caffeine can cause a transient rise in blood pressure as it is indeed a stimulant. “It causes the blood vessels to constrict, and it also increases your heart rate,” Dr. BALIGA explains. “Both of those things can contribute to raising blood pressure.”

However, Dr. BALIGA points out that the effect is usually small. A meta-analysis published in the journal Hypertension found that the impact of caffeine on blood pressure is modest, with an average increase of about 1-4 mm Hg in people with normal blood pressure.

How Long Does the Blood Pressure Spike last?

The blood pressure spike from coffee is temporary. “The effects of caffeine typically last for a few hours,” says Jessica Cording,R.D.. “So, if you’re sensitive to caffeine, you might notice a temporary increase in blood pressure for a couple of hours after drinking coffee.”

Cheng-Han Chen, MD, adds that the duration and intensity of the blood pressure increase can vary depending on individual factors such as caffeine sensitivity, frequency of coffee consumption, and overall health.

What Kind of Coffee Is Worse for Blood Pressure?

The brewing method and type of coffee can influence its effect on blood pressure. Filtered coffee might potentially be preferable. “Unfiltered coffee, such as espresso or French press, contains higher levels of cafestol and kahweol, which are compounds that may raise cholesterol and potentially blood pressure,” explains Cheng-Han Chen, MD.

Additionally, the amount of caffeine in different types of coffee can vary. A cup of brewed coffee typically contains more caffeine than a shot of espresso,but this can depend on the specific brand and preparation method.

Tips for Monitoring Blood Pressure at Home

The American Heart Association (AHA) suggests these steps for accurate home blood pressure readings:

• Remove clothing from the arm used for measurement.
• Sit still for at least five minutes before the reading (no talking or phone use).
• Sit with back straight and supported,feet on the floor.
• Support your arm on a flat surface.
• Position the cuff’s middle on your upper arm at heart level.
• Take multiple readings one minute apart, and record the results.

If you have hypertension or a family history, Dr. CHEN emphasizes consulting a healthcare professional about factors like coffee intake. “This is really a question for your doctor,” he says.
