How Soon After Should We Expect A Blood Pressure Rise With Coffee

Does Coffee Increase Blood Pressure?

Age, sex, habitual coffee consumption also need to be taken into consideration here. However, from the research the blood pressure effect begins at around about the 30 minutes mark. Certainly after 1 hour of coffee consumption, you should see the blood pressure effect of coffee quite vividly.

If you check your blood pressure at 30 minutes and 1 hour mark; you should know if your coffee has increased your blood pressure or not.

Is It Safe To Drink Coffee If You Have High Blood Pressure

Some people claim they can’t function completely without drinking their morning cup of coffee first. And although there are benefits to drinking coffee, the research on coffee intake and blood pressure is conflicting and inconclusive, says Barbara George, MD, the director of the Center for Cardiovascular Health Medicine at NYU Winthrop Hospital on Long Island in New York.

When it comes to blood pressure, it’s important to know your numbers. The top number of your blood pressure reading, systolic blood pressure, measures the force the heart exerts on the walls of arteries as it beats. The bottom number, diastolic blood pressure, measures the force when the heart is at rest. A blood pressure of less than 120/80 mm Hg is considered normal. A reading of; 130/80 mm Hg or higher is high blood pressure.

Here’s what experts need you to know about the research on coffee and high blood pressure and any precautions you should take.

Caffeine’s Effect On Blood Pressure

May 17, 2002 — The caffeine jolt of a java fix may cause a jump in blood pressure — a particular problem in people who already have high blood pressure. But don’t put your coffee cup down just yet. Researchers say the jury’s still out on the effects on caffeine on your heart.

This new study was presented today at the annual scientific meeting of the American Society of Hypertension in New York City.

Although there has been a lot of recent interest in studying how caffeine may affect the heart and blood pressure, the authors say it’s the first time an effect of caffeine has been found on the stiffness of arteries, an indicator of heart function.

In the study, caffeine quickly increased the stiffness of the large arteries in people with high blood pressure, said study author Charalambos Vlachopoulos, MD, of the department of cardiology at Athens Medical School in Greece, at a news conference.

Vlachopoulos and colleagues tested the effects of caffeine on the major arteries of 10 people who were being treated for high blood pressure and were an average of 62 years old. On alternating days, the participants were given either a pill containing 250 mg of caffeine or a placebo.

Thirty minutes after the caffeine was given, there was a big jump in the stiffness of their arteries, said Vlachopoulos. The effect peaked after 60 minutes and remained significant for at least three hours.

How Long Does The Effect Of Coffee On Blood Pressure Last

The blood pressure effect of coffee will last an average of about 3 hours. It could be longer or less but it is exepected that the blood pressure rise initiated by coffee will last an average of 3 hours.

Does coffee have a long term damage on cardiovascular health?

Does drinking coffee produce any long term damage on your cardiovascular health? Not really. The blood pressure increasing effect of coffee is in the short-term. When the subjects blood pressures were monitored over 24 hours in this study of tea, the caffeine effects on blood pressure were only seen in the acute phase but not in subsequent ambulatory BP readings.

This study also confirms the same theory too. It says that even though coffee does raise BP, there was no association between longer-term coffee consumption and increased BP or between habitual coffee consumption and an increased risk of CVD

In fact, this study tells us that coffee consumption is good for our cardiovascular health when drunk in moderate quantities. It says:

Moderate coffee consumption was inversely significantly associated with CVD risk, with the lowest CVD risk at 3 to 5 cups per day, and heavy coffee consumption was not associated with elevated CVD risk

So, we can safely say that in the long term, coffee consumption does not appear to cause any damage to our heart and blood vessels. Because the effect of coffee on blood pressure is temporary.

Caffeine Blood Pressure And The Heart

9 Negative Side Effects of Drinking Coffee: It

Evidence has repeatedly shown that consumption of caffeine does not increase the risk of high blood pressure, heart disease, or heart attack. One very well-known study examined more than 85,000 women over a ten-year period and found that there was no increased risk of these diseases, even in women who drank more than six cups of coffee per day. The Joint National Committee on Hypertension has specifically stated that there is no evidence linking coffee/tea and high blood pressure.

While some studies have shown a weak link between caffeine and elevations in blood pressure, the results are complicated and only consider short-term effects.

For example, one widely quoted study found that blood pressure rose slightly in subjects almost immediately after consuming a caffeinated beverage and that this blood pressure rise was more pronounced in people with pre-existing high blood pressure. However, these elevations were not very large and only lasted a short time. The study also showed that in about 15 percent of people with existing high blood pressure, drinking a caffeinated beverage actually caused a decrease in blood pressure.

Two important studies published in 2007 further supported the existing body of evidence by again demonstrating that:

  • Caffeine-induced blood pressure changes were small and short-lived
  • Caffeine does not contribute to disorders of the blood vessels associated with high blood pressure and cardiovascular disease

Potential Long Term Effects

While coffee temporarily increases your blood pressure right after you drink it, it does not seem to extend much beyond the short term.

For people with elevated blood pressure, existing literature shows that daily coffee intake is unlikely to substantially affect blood pressure or the overall risk of heart disease.

What Are The Complications Of High Blood Pressure

The longer high blood pressure is poorly controlled, the greater the damage to various tissues and organs in the body. Excessive pressure against the vessel wallscaused by high blood pressurecan lead to several long-term and potentially fatal consequences.

Heart attack or stroke: Hardening and thickening of the arteries cause poor blood perfusion to the heart or brain.

Aneurysm: Occurs due to the weakening of blood vessels that eventually bulge and rupture. This can be fatal.

Heart failure: High blood pressure requires the heart to pump harder to overcome the increased pressure. This causes the cardiac muscles to thicken and become inefficient, leading to heart failure.

Kidney failure: Similar to the heart, the kidneys are also sensitive to blood pressure and play a major role in blood pressure maintenance.

Coffee Raises Blood Pressure In The Short Term

The FDA recommends that adults dont drink more than 400 milligrams of caffeine a day, the average cup of coffee contains 80 to 100 milligrams of caffeine whereas a can of caffeinated soft drink contains 30-40 milligrams. According to a review of 34 studies, caffeine may raise your blood pressure, especially if you are not a regular coffee drinker. The review found that in general, drinking anywhere between 200-300 milligrams of caffeine can raise your systolic blood pressure by 8 mm Hg while boosting your diastolic blood pressure by 6 mm Hg. The caffeine, however, will usually only raise blood pressure levels for around 3 hours.

Is Coffee Good For Low Blood Pressure

Coffee is just a complex substance obtained from a coffee bean. The coffee beans were roasted to different temperatures, and the beans caramelized its sugar and produced a tangling aroma and lip-smacking drink.

But poor coffee beans were unaware that it would be blamed for peoples health.Five trials were conducted in the year 2011, 300 mg of caffeine was given.

And within an hour there was an increase in the systolic pressure of a human upto 8.1mmHg and there was also an increase in the diastolic blood pressure and this lasted for three hours.

The same amount of caffeine was given for almost 15 days, and there was no change in the blood pressure. Blood pressure remains the same.

Does Coffee Raise Blood Sugar And Insulin Levels

I know this topic is about coffee drinking and blood pressure but a quick word about coffee and blood sugar wouldnt go amiss for completeness. The reason is most people who have concerns about their BP reading when they drink coffee also worry about the effect of coffee on their blood sugar levels too.

Not to mention that they may be concerned about coffee and their insulin level.

Truth be told, just like coffee and blood pressure studies, the results for coffee and blood sugar are mixed.

For instance, this meta-analysis tells us that caffeine intake increases blood glucose levels. Not just that, in majority of the studies they pooled together, the study results suggest that caffeine intake whether it be from coffee or tea prolongs the period of high blood sugar levels.

Some other reports like this one did not make any significant association either way, so long as the intake of coffee or caffeine was limited to 2.5 mg/kg body weight per day.

The same could be said for relationship between caffeine and insulin levels and insulin sensitivity. Some studies suggest caffeine will raise insulin levels, other say coffee or caffeine has no effect on insulin.

Others like this one however indicate caffeine or coffee is good for type 2 diabetes. Meaning coffee has a protective effect and actually improves insulin sensitivity. So, consuming coffee means you need less insulin to drop your blood glucose levels.

Coffee Doesn’t Cause High Blood Pressure

March 26, 2002 — Although drinking a cup of coffee a day may slightly raise your blood pressure, it won’t likely increase your risk of developing high blood pressure.

In a new study, researchers say a connection between high blood pressure and coffee drinking has been discussed for decades, but no studies have actually established this link. Previous research has shown that coffee temporarily increases blood pressure immediately after consumption, but the body quickly adapts to that effect. Other studies have hinted that there might be a more persistent relationship between coffee drinking and the risk of developing high blood pressure over time.

In this study, which appears in the March 25 Archives of Internal Medicine, researchers tracked the coffee intake and blood pressure of a group of male medical school graduates for 33 years. They found that drinking one cup of coffee a day led to small increases in blood pressure, but long-term coffee drinking did not significantly increase the risk of developing high blood pressure.

People who didn’t drink coffee were less likely than coffee drinkers to have high blood pressure, but there was no progressive increase in risk associated with higher levels of coffee intake, according to the researchers.

The authors note that studies have shown that stopping coffee drinking can lower blood pressure in people who already have high blood pressure, and the results of this study may not apply to that group of people.

Coffee And Your Blood Pressure

Caffeine in Coffee: Does It Raise Your Blood Pressure?

Coffee has been part of the human diet for about 1,000 years. During much of that time, it has stimulated controversy and in the age of Starbucks, the dispute has blossomed from a tempest in a coffee pot to grounds for serious debate. Some of coffee’s negative press seems to depend on the widespread belief that anything that tastes so good must be bad for you.

But there is a serious side to the argument: Coffee stimulates the nervous system, increasing alertness. But many people are sensitive to even one cup of coffee, making them feel jittery or interfering with sleep.

High blood pressure is a common condition whereby the force of blood pushing against your artery walls is consistently too high. This pressure gradually causes your arteries to harden and narrow, which means the heart has to work harder to pump blood around the body. This mechanism can raise your risk of having a heart attack. Drinking too much coffee in a day may raise your blood pressure and worsen the condition.

Drinking more than four cups of coffee a day may increase your blood pressure, said the NHS.

The health body continued: If youre a big fan of coffee, tea or other caffeine-rich drinks, such as cola and some energy drinks, consider cutting down.

Its fine to drink tea and coffee as part of a balanced diet, but its important that these drinks are not your main or only source of fluid.

Research indicates that drinking too much coffee may increase blood pressure for a short time after consumption.

A review of 34 studies showed that 200 to 300 mg of caffeine from coffee which is approximately the amount two cups and more resulted in an average increase of 8 mm Hg and 6 mm Hg in systolic and diastolic blood pressure, respectively.

What Can I Do If Im Concerned About Caffeine And High Blood Pressure

If you are at all concerned about how your caffeine habit may be affecting your heart, here are a few things you can do to help ease your mind:

To sum it up: In most cases, a cup or two of your favorite caffeinated beverage in the morning wont cause any harm. Unless your doctor told you to specifically avoid it, its not something you should lose sleep over. The high blood pressure that comes right after drinking caffeine is temporary and wont make you any more likely to develop hypertension later in life.

Should People With Hypertension Avoid Coffee

A 2017 review concluded that people with high blood pressure should exercise some caution when drinking coffee but do not need to avoid it.

The review found that although there were older reports of a link between coffee drinking and hypertension, more recent studies suggested that 34 cups a day had either a neutral or beneficial effect.

A of 40 healthy regular coffee drinkers found that all types of coffee increased blood pressure but that the levels stayed within healthy ranges.

The increase in blood pressure was temporary but still measurable after consumption.

Some research suggests that the amount of coffee that someone drinks determines its effects on blood pressure.

As coffee contains many different compounds aside from caffeine, other compounds could be responsible for its effects on blood pressure.

However, a person could try switching to decaffeinated coffee to see whether their blood pressure decreases.

Some people find drinking coffee causes insomnia, anxiety, or tremors. Others may notice reflux and heartburn. Anyone who experiences these symptoms due to coffee should avoid drinking it.

According to researchers , regular coffee drinkers may experience withdrawal symptoms, such as headaches and low mood, if they suddenly stop consuming it. Therefore, if they wish to reduce their consumption, they should cut down the number of cups gradually.

Some alternatives to coffee contain caffeine, while others are naturally caffeine-free. People can try:

  • chicory coffee

Relationship Between Coffee And Blood Pressure

Can Caffeine Increase Blood Pressure?

Doctors often recommend not to consume Coffee before checking your blood pressure. It is regular advice which people have given to their fellow beings.

They think that drinking coffee would increase your blood pressure. But it is conflicting with the thoughts of the doctors opinions.

Doctors have analyzed deeply based on various researches conducted around Coffee and blood pressure.This debate is going on for the long term, and research that took place in 1987 by an Italian expert suggests that Coffee would decrease the blood pressure indirectly.

To have a deep understanding of this research, nearly 15 volunteers from the United States participated in an activity. Those 15 people were non-smokers, and they did not have any issues concerned with blood pressure. Amongst those 15, six of them were coffee lovers.
