Is Your Food Allergy Really A Histamine Intolerance
If you have food allergies, you know the drill: Eat so much as one crumb of the offending fare, and it can feel like your immune system is preparing for the apocalypse. Cue symptoms like hives, your stomach literally cramping your style, or even more dangerous signs that your body doesnt appreciate the culinary intruder, like trouble breathing.
But maybe your so-called food allergies arent what they seem. These and other symptoms could instead be a sign of histamine intolerance, a lesser-known condition that is basically a fancy way of saying you might have too much histaminethe chemical that causes allergic reactionsfloating around your body.
Its very easy to mistake symptoms of histamine intolerance for those of a food allergy, Joseph Dizon, M.D., chief of the Department of Allergy and Immunology at Kaiser Permanente West Los Angeles, tells SELF. In both cases, your bodys reacting to a surge of histamine, its just that the underlying mechanism is different. Confused? No worries. Heres everything you need to know about the difference between food allergies and a histamine intolerance.
And, of course, histamine is a critical part of allergic reactions, including those involving food. When you eat a food that your immune system has mislabeled as dangerous, it battens down the hatches by ordering your bodys mast cells to release histamine and other chemicals. This is what causes symptoms like itching, swelling, congestion, hives, and even full-on anaphylaxis .
Palpitations Of The Heart
Palpitations are a sensation or awareness of your heart beating. They may feel like your heart is racing, thumping or skipping beats. Almost everyone has had palpitations at some time in their life. They are usually associated with an abnormal heart rhythm .
Palpitations may have no obvious cause, but can be triggered by:
- physical activity
- nicotine
- illicit substances.
An occasional palpitation that does not affect your general health is not usually something to worry about. However, see your doctor if you have more frequent or consistent palpitations, which may be associated with a serious arrhythmia.
Why Does My Heart Skip A Beat
There are several possible causes of heart palpitations.
Trouble from above. Some palpitations stem from premature contractions of the heart’s upper chambers . When the atria contract a fraction of a second earlier than they should, they rest an instant longer afterward to get back to their usual rhythm. This feels like a skipped beat and is often followed by a noticeably forceful contraction as the lower chambers clear out the extra blood they accumulated during the pause. These premature beats are almost always benign, meaning they aren’t life-threatening or the sign of a heart attack in the making.
Two other heart rhythm disturbances that can cause palpitations from above are atrial fibrillation and supraventricular tachycardia. Atrial fibrillation is an irregular and often rapid heartbeat caused by chaotic electrical activity in the heart’s upper chambers. Supraventricular tachycardia is a faster-than-normal heart rate that begins above the heart’s lower chambers. Both of these may cause palpitations that may be brief or prolonged. Both should be evaluated by your physician.
Other sources. Problems with the heart’s timekeeper, called the pacemaker or sinus node, can cause palpitations. So can a breakdown in the coordination between the upper and lower chambers. Scar tissue in the heart from a heart attack or other injury and valve problems such as mitral valve prolapse can also lead to palpitations.

Are There Foods That Cause Heart Palpitations
A wide array of factors can trigger heart palpitations, a sensation that the heart is racing, pounding or even missing a beat 1. Causes may include anxiety, fear, stress, anemia, some medications and street drugs, hyperthyroidism, fever and heart valve disease. Certain foods and beverages, as well as dietary imbalances, also can set off this phenomenon, which is upsetting and bothersome although not usually a serious health concern, according to MedlinePlus. Talk to your doctor if youre experiencing palpitations.
Food Allergies And Heart Palpitations
Many people today live with food allergies and food sensitivity. While milk products cause reactions in some individuals, others cant tolerate nuts, certain fruits, or shellfish.

Often when I write about the best and worst foods for the heart, I talk in the context of heart-healing foods that are good to eat, as well as foods that should be avoided because they fan the flames of inflammation. Those discussions focus on how the things we eat and drink every day affect heart health over the long haul.
Today, though, I want to shift gears and focus on foods that can have more immediate and noticeable impacts on the heartstarting with foods that can cause heart palpitations. In this article Ill explore:

Coffee drinkers, think about the last time you drank one cup too many. You know what I mean!
If your heart is healthy and you have no history of arrhythmia or heart diseaseand youre not experiencing any other symptomstheres little need to worry about an occasional episode of these irregular beats. For people who do have arrhythmias or cardiac issues, however, its a different story. Palpitations caused by food can cause an existing disruption in your hearts rhythm to escalate, and potentially lead to a major event.
Diagnosis Of Heart Palpitations
Although not harmful in many cases, it is best to evaluate heart palpitations to know the underlying cause. The diagnosis of palpitations may include the following steps :
- Doctors may ask questions to exclude dietary factors, physical exertion, or panic attacks causing palpitations.
- Detailed medical history to know if the expecting mother has any existing heart problems.
- An electrocardiogram is often ordered to analyze the electrical activity of the heart. It may help diagnose arrhythmias and other rhythm abnormalities of the heart
- Blood tests to check for anemia, abnormal hormone levels, and other factors causing palpitations.
- Doctors may suggest wearing a heart monitor for a few days to notice irregular heartbeats if the other tests could not determine the cause.
- Coronary angiography is only done if there is an indication of underlying heart conditions.
Doctors may order a few more tests based on the underlying cause identified during the initial evaluation.

How Are Exercise And Pvcs Related
The relationship between extra beats and exercise is a complicated one. Many patients experience PVCs or palpitations before and after exercise, but not during exercise.
When most patients start to exercise, their own heart rate rises and the PVCs or other extra beats disappear at higher heart rates. After exercise, the bodyâs natural adrenalin level remains high for a period of time while the heart rate begins to go down during rest. This period of time often permits the extra beats to come back, and sometimes their rate and frequency are higher than before exercise.
If the other symptoms are mild or not present, usually there is not any reason for serious concern. If other symptoms accompany the palpitations such as shortness of breath, chest discomfort, or severe lightheadedness or loss of consciousness, those symptoms with palpitations in any setting are a cause for concern and require further evaluation.
How Common Are Allergies
Allergies are very common. About 1 in 4 people in the UK are affected by an allergy at some time during their lives. Each year the number of affected people increases.
It is estimated that half a million people in the UK have had an anaphylactic reaction to venom . Nearly a quarter of a million people under the age of 45 have had anaphylaxis due to nuts.
A manifesto from the European Academy of Allergy and Clinical Immunology published in 2017 is calling for concerted policy action to tackle the âallergy crisis in Europeâ. It points out that allergy is the most common chronic disease in Europe. Up to 1 in 5 patients with allergies live with a severe debilitating form of their condition they struggle daily with the fear of a possible asthma attack, anaphylactic shock, or even death from an allergic reaction. The manifesto proposes a series of evidence-based recommendations to tackle the burden of allergy in Europe, foster allergy research and help strengthen allergology as a medical speciality.

What Medications Are Usually Prescribed To Prevent Palpitations
There are a large number of medications that are used by physicians that are used to treat more serious types of heart rhythm disorders. These are usually prescribed by a heart specialist because they do have significant side effects and if not used correctly can cause serious cardiovascular problems, even a cardiac arrest or sudden death.
When used correctly, these powerful medications can prevent serious heart rhythm disorders from occurring and can be quite useful, although most patients would prefer not to be on them because of their cost, side effects, and they often must be taken multiple times a day.
Cocaine And Other Street Drugs
Illegal drugs like amphetamines, cocaine, and ecstasy are dangerous to the heart. Cocaine boosts blood pressure, raises heart rate, and damages the heart muscle. Amphetamines stimulate the nervous system, which ramps up your heartbeat. Ecstasy triggers the release of a chemical called norepinephrine, which makes the heart beat faster.
