Why does caffeine make me dizzy: Why Does Coffee Make Some People Feel Dizzy or Sick?

Why Does Coffee Make Some People Feel Dizzy or Sick?

Does your morning cup of coffee sometimes make you feel dizzy or nauseous? Does sipping on a cup of coffee cause lightheadedness?

If so, you’re not alone, there are a number of people who sometimes feel dizzy or sick after drinking coffee, and there is an explanation.

While we all metabolize and react to coffee differently, it’s probably one specific compound within the coffee that is leading to these sudden dizzy spells. It probably won’t come as a surprise to most people, but the caffeine content in your daily cup of coffee could be the reason you don’t feel well after drinking it.

Yes, there are many different compounds that make up your cup of coffee, but caffeine sensitivity is typically what leads to the feeling of dizziness or nauseousness after drinking a cup. But why would you suddenly have a reaction to your cup of coffee now, when you’ve been totally fine drinking it for years?

Why Does Caffeine in Coffee Make Me Dizzy?

Caffeine intake may not always cause you to feel dizzy or uneasy, but under the right circumstances you could experience feelings you’ve never felt before.

Caffeine is a stimulant that makes your heart beat faster while also causing your blood pressure to rise. Because of this, if you consume too much caffeine, or there are other changes to your body occurring, you may experience some unwanted side effects.

Some of the symptoms you may start to notice if you develop a sensitivity to caffeine can include the following:

  • Dizziness
  • Headaches
  • Nausea
  • Rapid Heartbeat
  • Restlessness and Insomnia
  • Anxiety or General Uneasiness
  • Jitters
  • Diarrhea

These symptoms can happen after your first sip of coffee, or after years of daily drinking. Our bodies tend to change as we age, and certain factors may come into play as you get older that may not have affected you when you were younger.

Caffeine Sensitivity

The most common cause of dizziness when drinking coffee is related to caffeine sensitivity. This means that your body’s nervous system overreacts to the introduction of caffeine (a stimulant) as it is digested. This sensitivity can come from a number of things and not just genetics, although that is one of the causes.

Outside of a genetic predisposition to being sensitive to caffeine things like age and health conditions can play a major role.

If you already suffer from high blood pressure, anxiety, or reflux, then caffeine and coffee can exacerbate the symptoms associated with those issues and cause you to feel dizzy or lightheaded.

Certain medications that you are on, such as antibiotics, blood pressure medication, antidepressants, and others, can also interact with the caffeine and cause heightened side effects as well.

If you’ve noticed that you recently started experiencing dizziness after drinking coffee, then the first thing we would do is see if anything else in your life has changed. If you’ve started taking new medications or supplements, you can talk to your doctor about your caffeine intake to better determine if those might be causing some unwanted side effects.

Drinking Too Much Caffeine

In addition to caffeine sensitivity, there’s also a chance that you’re drinking more caffeine that normal and just don’t realize it.

Drinking excessive amounts of caffeine can also cause side effects that you may not have experienced before. So, take a second to think if you’ve consumed more coffee than you normally do in the span of a day or week to help determine if that could be causing you to become dizzy.

You could also be consuming caffeine from other sources in addition to your coffee and not even realize it. Some supplements have higher level of caffeine and when combined with coffee can make you feel sick.

Or maybe you haven’t drank a lot of coffee in a while and then decide one day to enjoy a large cup one morning. Your body may have lost its tolerance from the caffeine, which can also cause you to react differently than you normal might have while you were drinking it consistently.

Lifestyle Changes

Believe it or not, certain lifestyle changes could also be causing the caffeine and coffee to affect your body differently.

An influx of stress in itself can cause a feeling of uneasiness or jitters, and when combined with a stimulant like caffeine, it can enhance those effects and make you feel even worse.

The same goes with a lack of sleep. While caffeine is known to help people stay awake, it can also cause you to have disruptive sleep. Not getting a good night sleep, or being sleep deprived, can lead to dizziness, headaches, and lightheadedness on its own, so when you combine that with large amounts of caffeine, you may be making the issue worse.

Coffee and Your Health

While there are many health benefits that come from drinking coffee, caffeine doesn’t always agree with everyone.

As with all things, caffeine should be consumed in moderation. If you start to notice yourself feeling dizzy or lightheaded after drinking coffee, then you should take a look at your lifestyle and see if anything has changed recently. If you can’t easily find a reason as to why you may be reacting to caffeine all of a sudden, then it may be time to reach out to your doctor to get their opinion.

In some cases, switching to decaf coffee or limiting the amount of coffee you drink, will make the dizziness and nausea go away, but if it continues there may be something more serious going on that only your doctor would be able to help with.

Caffeine and coffee are a great way to get that extra pep in your step first thing in the morning, or during that after lunch lull, but your overall health is more important. Being aware of what caffeine can do to your body will help you be aware of any changes you may experience due to overconsumption or interaction with other medications or supplements.

If you’re anything like me, you cannot wait to wake up and grab your favorite cup of morning java to jump-start your day. Also, if you’re like me, you may take a few sips and wind up asking yourself why the room is spinning.

Daily coffee drinkers have probably experienced a bit of dizziness after drinking a cup of Joe at one time or another.  There are a few reasons why coffee makes me dizzy and lightheaded, and the cause is likely behind your woozy reactions as well.

Recommended: The Pros and Cons of Coffee

Coffee is a stimulant

A fact we often overlook is that caffeine is a drug,  a stimulant at that. Many of us grab a cup of coffee and treat it like liquid breakfast. Half the time, we are doing this before we put any food in our bellies.

Far too many of us do it, though it’s not a good idea.  The average American coffee drinker downs 3 cups a day, and most do it on an empty stomach within their first hour awake.

Caffeine consumption on an empty stomach will create stomach lining eroding acid and most certainly cause jitters.

Don’t skip breakfast

I know for a fact that coffee makes me dizzy and lightheaded whenever I skip the bagel and down my coffee to become more alert. This act may be a bit counterintuitive, however.

While coffee is indeed a stimulant, it is an adenosine receptor antagonist—the receptor kind of tricks the brain into being alert. Over time, caffeine intake can create a feeling of drowsiness as your body produces more adenosine in response.

As you begin to build up a resistance to the inhibitor, you’ll need more coffee to feel alert. When this occurs, I, of course, want to drink more coffee. As my intake increases, I may drink it without food, and soon my coffee makes me dizzy and lightheaded once again.

Is the caffeine making you dizzy?

In a word, yes. Like most stimulants, caffeine reduces blood flow to the brain. Ingesting coffee before you eat or in large quantities can result in the giddy, jittery, or woozy side effects often associated with coffee drinking.  

When coffee makes me dizzy or lightheaded nowadays, I try to ask myself why. If I retrace my steps, I can often find the culprit, which helps me reduce incidents of grogginess in the future.

If you find coffee making you jittery far more often than you would like, do what I do and ask yourself the following questions.

Am I drinking too much a day?

The MayoClinic has advised against ingesting large quantities of coffee, stating that up to 400 mg (roughly 4 cups) a day appears safe. Drinking more than this can create a ton of side effects, including a higher incidence of dizziness. The same goes for energy drinks. The effects of caffeine can include insomnia, nervousness, irritability, high blood pressure, and the dreaded shakes that stem from becoming lightheaded.

Did I drink enough water? 

Coffee is not only a stimulant but is a diuretic as well. It causes water and electrolyte loss. Whenever coffee makes me dizzy and lightheaded, I grab a glass of water or water bottle and chug. Increasing my water volume keeps me from becoming dehydrated and eventually reduces my tremors.

Have I eaten breakfast?

A stated previously, food intake is important. Not eating an adequate breakfast before taking that espresso shot could be why your heart is racing, and the room is spinning. I find simply getting a sausage, egg, and cheese biscuit is enough to calm my body down eventually.

Caffeine tolerance is a factor

Now, bear in mind some people can drink buckets of coffee and not be affected, while someone else can barely drink half a cup and immediately feel the negative effect of caffeine. The trick here is to ask yourself what you can handle.

Once you discover your tolerance level, try your best not to overdo it. Keeping a watchful eye on the amounts of caffeine you intake can help you enjoy an occasional cup without being thrown off balance.

When I began to look at how and when I indulge, I never had to ask why coffee makes me dizzy and lightheaded. I could look at my habits and self-correct.

As they say, knowledge is power, and knowing what I can do to make sure I can keep on enjoying my morning cup, has enabled me to continue starting my day with a spring in my step!

Happy Caffeinating!

How does coffee affect blood vessels and the brain?

back

“It is worth tasting coffee, everything seems to flash, and thoughts crowd like battalions on the battlefield” – the words of Honore de Balzac, a well-known connoisseur of the drink. It is said that his daily dose reached 50 cups of strong coffee. Throughout the history of this drink, the impression has been that it goes hand in hand with the muse of many geniuses. Is this due to the effect of caffeine on mental activity? And how does coffee affect the vessels of the brain?

COFFEE AND INTELLIGENCE. IS THERE A RELATIONSHIP?

Let’s answer the question right away – there is no connection. But there is a direct impact on performance. This is because caffeine stimulates the heart rate, which means it increases blood supply, including to the brain.

After drinking a cup, the majority notes not only an increase in concentration, but also the speed of simple physical actions. For this reason, many gym goers drink a cup of espresso or americano an hour before their workout. Physical activity is easier, movements become clearer, and there is enough energy until the end of the session.

But the speed of work and quality are two different things, so it’s not worth looking for the relationship between genius and love for coffee.

HOW DOES COFFEE AFFECT THE VESSELS OF THE BRAIN?

A frequent question for those who think about their health. Caffeine is known to constrict blood vessels in the brain. This explains the effect of the “pills”, when after strong coffee the headache becomes less or completely disappears. At the same time, the vessels of the peripheral system expand under the influence of caffeine. Hence, for some time, hypotension increases blood pressure.

Any food and drinks have a similar effect on blood vessels – the body produces adrenaline, blood and oxygen enter the tissues faster. Therefore, for a healthy person, moderate consumption of a fragrant drink gives only a positive effect.

The health benefits of coffee are still not fully understood. For example, scientists are now studying the link between coffee consumption and a reduced risk of Alzheimer’s and Parkinson’s disease.

HOW TO DRINK COFFEE CORRECTLY

Here are some simple rules, following which you can enjoy great taste without harm to your health:

  • Drink coffee in small portions. A small cup of strong espresso is enough to recharge your performance batteries.
  • do not exceed 3-5 coffees per day. They contain approximately 400 mg. caffeine is the recommended daily allowance for this substance for an adult.
  • choose only quality coffee, instant or in beans. This directly affects the taste, benefits and your enjoyment of the drink. can be sure of the quality of the purchased product for coffee machines.

Many people start their day with a cup of coffee, which can invigorate and improve mood, however, some may feel dizzy after drinking the drink. About what this may be connected with, “Public News Service” found out from experts.

Thus, experts note that poor health can be caused by an overdose of coffee. If too much caffeine enters the body, the brain can desensitize receptors that stop transmitting signals to other organs in order to avoid overstraining the cardiovascular system. Another reason that can cause dizziness is the sensitivity of the body if the symptom occurs after one cup of coffee. This is usually characteristic of hypertensive patients and people with weak blood vessels.

In addition, dizziness can be due to hormonal causes, and this often happens in adolescents. In this case, experts advise them to give up the drink.

At the end of June, scientists from Jiao Tong University in Xi’an found out that in the presence of hypertension and other diseases, drinking coffee increases the risk of calcium deposits on the walls of the abdominal aorta, and therefore the risk of stroke and heart attack.

Previously, scientists from the University of Haume I disproved the myth about caffeine.
