Heart Palpitations After Eating

A 2017 review of energy drink use in the United States reported that out of 496 college students who consumed energy drinks in the last month, 19 percent experienced heart palpitations. However, because there are a range of ingredients in these drinks, researchers were unable to draw definite links between caffeine and palpitations.

Understanding Heart Palpitations After Eating

A heart palpitation is when it feels like your heart skipped a beat or had an extra beat. It may also feel like a fluttering or pounding in the chest or neck and can accompany a sudden increase in your heart rate.

You may experience heart palpitations after eating. This can be due to a variety of factors, from the contents of your last meal to dietary supplements you may be taking.

Heart palpitations are common and can be harmless. However, they can be indicators of serious underlying conditions.

In this article, we detail why you may get heart palpitations after eating, what you can do to treat them, and when to see a doctor.

You may experience heart palpitations after eating for several reasons.

Preventable medical errors kill about 22,000 patients a year, according to research from the Yale School of Medicine. That’s much less than a previously reported number of 250,000 deaths a year where medical error is to blame.

Diet

Your overall diet can play a role when it comes to heart palpitations after eating.

The following are some diet-related triggers and risk factors:

Low potassium levels and dehydration can trigger heart palpitations.
If you have hypoglycemia, or low blood sugar, you may be at higher risk for having heart palpitations due to your diet. High carbohydrate foods and processed sugars can cause palpitations if you have issues with low blood sugar.
Alcohol can also play a role. Researchers in a 2016 review of studies found a link between alcohol consumption and atrial fibrillation, which can lead to palpitations.
You could have palpitations due to a food allergy or sensitivity. Eating spicy or rich foods can also trigger heart palpitations.
High sodium foods can also cause palpitations. Many common foods, especially canned or processed foods, contain sodium as a preservative.

Meal experience

Heart palpitations after eating may be related to the meal experience rather than the food.

Palpitations can occur due to the act of swallowing. You may sometimes feel palpitations when standing up after being seated for a meal.

Emotions can also trigger palpitations, especially if your mealtimes cause anxiety or stress.

Caffeine

Doctors may recommend you cut down on caffeine if you’re experiencing heart palpitations.

Caffeine is in many popular foods and drinks, such as:

However, research into the link between caffeine consumption and palpitations has provided mixed results.

A 2017 review of energy drink use in the United States reported that out of 496 college students who consumed energy drinks in the last month, 19 percent experienced heart palpitations. However, because there are a range of ingredients in these drinks, researchers were unable to draw definite links between caffeine and palpitations.

A 2016 study suggested that caffeine likely does not cause palpitations. In fact, the researchers proposed that some types of caffeine can improve your heart health. A further 2018 study similarly found no basis for linking caffeine intake and irregular heart rhythms.

The most helpful treatment options for heart palpitations will depend on what’s causing them.

Your doctor may conclude that your heart palpitations are not a serious threat to your health. In this case, you’ll likely benefit from lifestyle changes.

For example, if you experience palpitations after eating, you may benefit from recording your food habits and looking for triggers. Avoiding these in the future may help resolve symptoms.

Other lifestyle changes, such as quitting smoking, can also help.

If your palpitations are a serious issue, your doctor will likely prescribe a beta-blocker or calcium channel blocker. These are antiarrhythmic drugs. They keep your heart rate even and regular by improving blood flow throughout your body.

What to expect at the doctor’s office

Your doctor will likely begin with a physical exam. If they suspect a heart problem, you may need to see a cardiologist. Diagnostic testing may include:

blood tests
urine tests
an electrocardiogram
an echocardiogram
a stress test

Your doctor may also recommend a Holter monitor test. For this test, you’ll carry a portable heart rate monitor with you for 1 to 2 days or longer so your doctor can analyze your heart rate over a longer period.

Exercise can make you prone to having heart palpitations. Some mental health conditions such as anxiety disorders can also increase your likelihood of experiencing heart palpitations.

Drugs

Other causes include:

over-the-counter products, such as cold medications and decongestants with a stimulant effect
medications for asthma
medications for heart disease
medications for high blood pressure
thyroid hormones
certain antibiotics
amphetamines
cocaine
nicotine
cannabis

Hormonal changes

Significant changes in your hormones can cause palpitations, too. Going through a menstrual cycle, pregnancy, or menopause affects your hormone levels, and these changes can have a noticeable effect on your heart rate.

Hot flashes during menopause are notable for causing palpitations. These usually disappear when the hot flash is over.

Heart palpitations usually stop after a few seconds once your heart rate returns to normal. In some cases, your heart might continue to beat erratically for minutes or more. You might feel pain in your chest and even pass out.

Heart palpitations can be a symptom of a medical condition, including:

anemia
dehydration
blood loss
low blood sugar levels
shock
infection

Treating these underlying causes can help prevent further palpitations.

If you’re under a lot of stress, therapies such as yoga, meditation, and deep breathing techniques can help alleviate heart palpitations. Making sure you drink plenty of fluids can also help.

You may be more likely to experience heart palpitations if you have:

low carbon dioxide levels in the blood
low oxygen levels in the blood
low potassium levels
an overactive thyroid

Some conditions can increase your risk of heart palpitations. These conditions include:

diabetes mellitus
hypertension, or high blood pressure
obstructive sleep apnea
coronary artery disease

If you have heart palpitations, talk with a doctor about getting tested for heart conditions, especially if you have other conditions that can affect your heart’s health.

Talk with a doctor about your heart palpitations and getting evaluated for heart conditions. If tests show your palpitations are not due to an underlying medical condition, you may not need medical treatment. If you have palpitations often, try to figure out what foods or activities trigger them.

Keep a food diary to see if you can identify specific foods that give you palpitations. In some cases, a single ingredient in your food may be causing them. If you can identify triggers, avoid them and see if the palpitations stop.

Taking other preventative measures to reduce stress or anxiety may also help.

No matter what’s causing your palpitations, many treatments are available to help keep your heart rate and rhythm in check.

Overview

What are heart palpitations after eating?

Heart palpitations feel like your heart races, pounds, flutters or skips a beat. You may notice your heart rate when you have a palpitation. Or you may feel your heart beating in your throat, neck or chest.

Heart palpitations can happen anytime, including after or while eating. Though palpitations can seem scary, they usually aren’t dangerous.

How common are heart palpitations after eating?

Heart palpitations after eating are very common. They may occur if you have food allergies or sensitivities.

An increased heart rate happens to many people throughout the day. But you’re more likely to notice heart palpitations when you aren’t distracted. You might sense them when you’re sitting still, resting or lying down.

Symptoms and Causes

What are the symptoms of heart palpitations after eating?

Symptoms of heart palpitations include:

Fluttering: You may feel a flapping or fluttery feeling in the chest. Your heart can feel like it’s doing flips.
Irregular heart rate: Your heart might feel like it’s skipping a beat, beating out of rhythm, or speeding up and slowing down. It can also seem like your heart stops for a second or two.
Pounding: You might feel like your heart is beating very hard. Some people who have heart pounding say they can hear their heartbeat in their ears.

What causes heart palpitations after eating?

Usually, heart palpitations are harmless. They can occur due to the chewing, swallowing and digestive process or because of ingredients you eat. Most palpitations don’t mean you have an underlying health problem.

What foods can cause heart palpitations after eating?

Foods that may cause heart palpitations include:

High-carbohydrate foods, which can spike blood sugar levels, particularly if you have low blood sugar (hypoglycemia).
High-sodium foods, such as processed or canned foods.
High-sugar foods, especially if you have hypoglycemia
Spicy or rich foods, which can cause heartburn and sometimes a quickly beating heart.

Certain ingredients in food may also trigger heart palpitations:

Monosodium glutamate (MSG): Processed foods and some restaurant meals may contain this flavor-enhancer. People who are sensitive to MSG may have heart palpitations.
Theobromine: Chocolate contains this naturally occurring compound found in cacao plants. Theobromine can increase heart rate, which leads to palpitations.
Tyramine: Alcohol, aged cheeses, cured meats and dried fruit contain this amino acid. Tyramine can raise blood pressure and cause heart palpitations.

What supplements can cause heart palpitations after eating?

Taking dietary supplements with meals can sometimes lead to heart palpitations. These supplements include:

Bitter orange, taken for heartburn, skin health and weight loss.
Ephedra, taken for colds, energy and headaches.
Ginseng, taken for energy.
Hawthorn, taken for heart conditions.
Valerian, taken for anxiety, depression and sleep.

What medications can cause heart palpitations after eating?

Certain medications, which you might take with food, can also lead to heart palpitations. These medications include:

Allergy, asthma and cold medicines.
Antibiotics.
Diet pills.
Heart disease medications.
High blood pressure medications.
Insulin.
Thyroid medications.

Are there other causes of heart palpitations after eating?

Other causes of heart palpitations related to eating and drinking may include:

Anemia (low red blood cell count), which can result from a lack of iron in your diet.
Dehydration when you don’t drink enough water.
Drinking alcohol, which may lead to atrial fibrillation (irregular heart rhythm that starts in the heart’s two upper chambers).
Feeling anxiety or stress before, during or after a meal.
Low potassium levels (hypokalemia), which can cause arrhythmia.

Less commonly, heart palpitations after eating can be signs of a heart condition. If your heart often races after eating, see your healthcare provider for an exam. Seek help immediately if you have palpitations and chest pain or trouble breathing.

Does caffeine cause heart palpitations?

Caffeine is a stimulant found in coffee, chocolate, energy drinks, tea and soda. Providers used to think that caffeine led to heart palpitations. But recent research suggests that, in moderation (up to three cups a day), caffeine may actually have heart benefits. If you drink more than three cups per day, you may notice palpitations.

That said, some people may be particularly sensitive to caffeine, even at low levels. Also, in rare cases, drinking large amounts of energy drinks high in caffeine may cause arrhythmias.

Diagnosis and Tests

How do healthcare providers diagnose heart palpitations after eating?

Your provider will listen to your heart to check for murmurs or other sounds. They will review your:

Current medications, including herbal supplements.
Diet.
Lifestyle.
Medical history.
Symptoms.

Your provider may recommend a blood test (complete blood count or CBC) to look for anemia or low potassium. They’ll also check for a thyroid problem or other health issues that could lead to heart palpitations.

Can my provider rule out a heart problem as the cause of heart palpitations after eating?

Your healthcare provider may suggest other tests to check your heart health. These tests include:

Chest X-ray, which provides images of your heart and lungs.
Echocardiogram (echo test) to show your heart’s function in motion.
Electrocardiogram (EKG or ECG) to monitor your heart rate and rhythm.
Exercise stress test, which studies your heart’s rhythm and performance.
Holter monitoring to record your heart’s activity over 24 to 48 hours.
Event recorder to track your heart over weeks and enable you to record heart palpitations when you have them.

Management and Treatment

How do providers treat heart palpitations after eating?

Treatment for any kind of heart palpitations depends on the diagnosis. Many times, palpitations aren’t serious. They often go away on their own.

Providers may recommend that you make lifestyle changes to control your symptoms. These changes may include:

Finding ways to cope with stress.
Getting adequate sleep.
Increasing exercise.
Meditating.
Practicing yoga, tai chi or other forms of mindful movement.
Quitting smoking.

How do I manage heart palpitations after eating?

Keeping a journal of your symptoms after you eat will help you notice what might trigger your palpitations. Make sure to note:

What food and drinks you consume when your heart palpitations occur.
What you’re doing when the palpitations start.
How long the palpitations last.

Prevention

How can I reduce my risk of heart palpitations after eating?

To lower your risk of heart palpitations:

Get treatment for anxiety or depression. You can talk to your provider about antidepressant medication or other medicines. Therapy might help, too.
