We sprung the calendars forward this week, and it is formally allergy season, the proper time to nail down what causes allergy symptoms and how you can keep away from them, as a result of, let’s be sincere:

Nobody needs seasonal allergy symptoms. Nobody.

So let’s get to it! On this put up:

  • What causes allergy symptoms
  • The Allergic Response (aka what occurs in your physique when you’ve got an allergy)
  • Histamine and antihistamines
  • The right way to keep away from seasonal allergy symptoms


Allergic reactions are immune responses to exterior substances that don’t usually trigger a response in different folks uncovered to the identical materials — for instance, pollen, peanuts, bee venom, and extra.

Your immune system recognises these substances or “triggers” as a “dangerous” agent, and it creates a sequence response to the place it produces antibodies to “shield” you from the overseas substance. This leads to infected sinuses, pores and skin, airways or the digestive tract and system.

What causes allergy symptoms is then a mix of your genetic predisposition to a certain set-off or allergen and your physique’s immune system response to it.

The severity of the allergy isn’t relying on the allergen; however, on the person immune response, going from a minor irritation or sneeze, to a doubtlessly life-threatening situation known as “anaphylaxis.”


There are several sorts of allergens. However, these are the commonest ones inflicting allergy symptoms within the US.

  • Airborne: pollen, mud mites, mildew,  fragrance, animal fur. Bronchial asthma, a standard consequence of airborne allergens affects24 million folks within the US.
  • Insect Stings: bees, wasp or mosquito bites 5% of the inhabitants presents insect bite allergies
  • Medicines: penicillin or penicillin-based antibiotics, usually. 10% of Individuals report a penicillin allergy.
  • Meals: nuts, peanuts, soy, wheat, soy, shellfish, fish, eggs, and dairy. Over 4.Four million youngsters within the US have been recognised with food allergies.
  • Latex: or different substances relative to the touch. 1 to six % of Individuals have a latex allergy


There isn’t any definitive reply as to what causes allergy symptoms and why some individuals are affected by a specific allergy, whereas others dwell allergy-free lives, even when they’ve markers for it.

Nonetheless, research present that each genetics and environmental elements are necessary within the growth and rise of allergy symptoms.

It’s potential that the first time an individual is available in contact with an allergen their physique could not produce a response, however, save the data gathered by the immune system and label an innocent factor as a threatening one. As soon as the person is sensitised to that particular allergen future exposures will produce an allergic response, starting from delicate to critical.

  • Genetics and Hereditary Circumstances: a baby has a 30 to 50% probability of inheriting a bent to be allergic if one among their dad and mom are allergic. Sufficient, the allergens that affect the mentioned baby would not have to be the very same one.

    For instance, an individual with bronchial asthma could have a baby with a peanut allergy and vice-versa. If each dad and mom are allergic, the chance of presenting allergy sensitivities elevated to 80%. Genetic predisposition may additionally be associated with gender, with the mom being an extra doubtless agent in passing allergy sensitivities to a feminine baby and fathers to a male baby.

  • Environmental Elements: the “atmosphere” you reside in will expose your immune system to a specific set of triggers that may improve or lower the chance of creating or uncovering an allergy.

    For instance, people residing in a family with animal fur could discover that they’re extra liable to allergic reactions to canine hair than somebody by no means uncovered to it.

  • Earlier Medical Circumstances: one of many least anticipated elements that will doubtlessly be what causes an allergy in a household with no identified allergy symptoms – is a higher respiratory an infection. Respiratory system infections in six-month-old infants usually tend to turn into allergy symptoms or bronchial asthma in a while in life, no matter whether or not they’re bacterial or virus-related.

There isn’t any identified ultimate treatment for allergy symptoms. However, a nutritious diet, preventative drugs and well-being practices could cut back and utterly keep away from allergic assaults. Moreover, there are several therapy choices to handle these circumstances, relying on what causes allergy symptoms and their severity in your physique.

Everyone seems to be different; however, this is what’s occurring once you see allergy signs – and a few of our pure options.


To preserve your physique secure, your frame triggers a sequence response that ends in both mildly discomforting allergy signs or life-threatening ones. We break it down for you:

  • The immune system reacts to a substance and mislabels it as “dangerous” in the course of known as “sensitising.”
  • When uncovered to mentioned substance on a brand new event, the immune system produces immunoglobulin E often known as IgE and antibodies for every recognised
  • The antibodies “assault” the allergen
  • Chemical substances are known as “histamines” are launched from “mast cells” rejecting and flushing out the allergen. Folks typically assume that is what causes allergy symptoms.
  • Histamines trigger irritation so that the immune system can “restore” the harm
  • You expertise signs within the several areas of the physique together with bodily reactions within the pores and skin, throat, nostril, lungs, throat, ears, sinuses, abdomen lining, and so forth.

Associated Points:

Extreme allergic reactions could become additional problems; these are the highest associated points to identified allergy symptoms:

  • Anaphylaxis:  an allergy-induced response the place respiratory is restricted and/, or extreme swelling of the lips, throat, tongue or fingers (in addition to different physique components) happens. It could additionally result in dizziness and lack of consciousness. Anaphylaxis is generally linked to meals, treatment, touch-based, and bug sting allergy symptoms than to airborne allergens
  • Bronchial asthma: immune system response the place the airways and respiratory are constricted, resulting in air loss, choking and coughing. Bronchial asthma is usually linked to airborne allergens.
  • Sinusitis: irritation of the cavities across the nasal passage, it could turn into a continual situation. Some folks consider that sinusitis is what causes allergy symptoms. However, it’s usually the opposite means round.
  • Ear and Lung Infections: ear ringing and clogging in addition to higher respiratory (lung infections) could also be linked to an allergic response the place sinus is affected and impeding right air passage in addition to mucus launch.

If you happen to’re asking your self: Can allergy symptoms trigger sore throat? Can allergy symptoms trigger coughing? Or Can allergy symptoms trigger fever or hay fever?

The reply is sure: these are all a part of the immune response to allergens, the place the sore throat is the results of irritation, coughing the consequence of nasal leaking or histamine response (for expulsion), in addition to itchiness within the pores and skin and some circumstances fever.


The immune response to allergens brings out histamine manufacturing, and we fight it with prescription and over-the-counter antihistamines. Right here’s a short definition of each:


A natural nitrogenous compound that participates within the immune response in opposition to allergens, however, that additionally regulates physiological perform within the intestine and acts as a neurotransmitter for the mind, uterus, and spinal wire. It’s a vital issue within the management and regulation of the itching sensation.

Histamines are instructed by the immune response that there’s an allergen and act as membership bouncers to get the “undesirable” factor out of your system, through the mucus of the nostril or pores and skin. What causes allergy symptoms to feel uncomfortable and make us take discover.

Histamines have several motion mechanisms:

  • Vasodilation: histamine causes blood vessels to open up and launch strain.
  • Blood Stress Drop: resulting from its vasodilation properties, blood strain could drop beneath elevated histamine presence.
  • Nasal Mucus: vascular permeability permits mucous fluid to flee, resulting in runny noses, hyper-mucus secretion, watery eyes, and nasal/sinus congestion.
  • Gastric Acid Reflex activation and acid manufacturing
  • Protects in opposition to convulsion, stress, denervation and ischemic lesions
  • Might have a task to play in sleep and wake cycles


Histamine binds with particular receptors situated in numerous cells across the physique to trigger the immune response we all know as “allergy” signs. Antihistamines are chemical substances that cut back the uncomfortable results of histamine in these cell receptors, in the end offering aid for something from nasal congestion to hives.

Antihistamines, merely put, create an opposing response to histamine receptors. These medicines usually are out there OTC and are very efficient (they’re what causes allergy symptoms to go away!)

The most typical prescription an over-the-counter antihistamines are:

  • Desloratadine
  • Azelastine
  • Hydroxyzine
  • Cyproheptadine
  • Levocabastine

Nonetheless, there are additionally pure antihistamines it’s possible you’ll wish to think about as a substitute possibility in case you don’t know what causes allergy symptoms in your particular situation.

  • Vitamin C
  • Flavonoids like Quercetin out there in citrus fruits, apples, parsley, tomatoes, broccoli, lettuce and even onion and garlic.
  • Omega-three Fatty Acids
  • Bromelain (ordinarily present in pineapples!)
  • Probiotics


Say wholesome and keep away from these pesky reactions with these easy steps you possibly can implement at present:

  • Keep away from Identified Allergens: if you already know what causes allergy symptoms for you, then merely be sure you keep away from the triggers that result in an allergic response. If you happen to don’t know what your triggers are thought about getting examined.
  • Take away Outerwear: in case you’ve been outdoor working towards sports activities, going for a stroll or simply being uncovered to the weather, you may cut back the probabilities of an allergy assault by merely eradicating the objects of clothes you have been sporting outdoors; the longer the publicity the extra an environmental issue could come into play.
