Allergies are one of the most common chronic diseases on the planet.

Simply explained, an allergic reaction happens when my immune system misidentifies an innocuous substance as a threat.

But where to start?

Its hypersensitivity to an allergen can cause a variety of symptoms, ranging from moderate but bothersome to life-threatening. Although allergies cannot be cured, there are several ways to avoid and treat them.

So, let's have a look at some allergy statistics.

#01. Allergic Rhinitis Affects Between 10-30% of the World's Population

Hay fever, also known as allergic rhinitis¹, is the most common allergy, affecting 10%–30% of adults and 40% of children around the world.

Seasonal and perpetual symptoms are both possible. Seasonal symptoms might emerge in the spring, summer, and the beginning of the fall season.

People with persistent symptoms, on the other hand, are more likely to have symptoms throughout the year.

#02. According to Pollen Allergy Statistics, Hay Fever Is More Common in the Spring

Sensitive persons are more likely to develop symptoms after inhaling tree, grass, and weed pollens, as well as mold² spores, in the spring.

The most frequent allergy treatments are reducing allergen exposure, getting allergy injections, and taking medication.

#03. Vitamin D Has Been Shown to Significantly Lessen the Likelihood of Getting Allergies

According to allergy³ facts, Vitamin D can effectively cure allergy symptoms such as hives in the body.

Vitamin D insufficiency in infants has been related to eczema and allergies, according to a study published in the Journal of Pediatrics.

#04. Around 2.5% of the World's Population Suffers From Food Allergies

In 2025, nearly one-third of U.S. adults and over one-quarter of U.S. children reported experiencing seasonal allergies, eczema, or food allergies, based on new data from the CDC's National Center for Health Statistics.

It's difficult to pinpoint the prevalence of food allergies because there are so many variables that can skew the results.

Geographic variations, study techniques, nutritional exposure, and age are only a few examples.

#05. Food Allergies Account For Almost 50% of All Anaphylactic Reactions

Anaphylaxis⁴ is a life-threatening systemic reaction that usually happens minutes or hours after a person consumes certain foods.

#06. Allergy Statistics on Asthma Reveal That 64% of Asthma Cases Are Caused by Living in a City

Four Indian cities, Kanpur, Kolkata, Varanasi, and Lucknow, as well as Orlu in Nigeria, had the lowest rates of childhood asthma.

On the other hand, Kuwait, with 550 cases per 100,000 children, had the largest national burden of lung illness, followed by Canada, Qatar, Taiwan, and the United Arab Emirates.

#07. According to Allergy Statistics, Asthma & Allergies Frequently Coexist

Pollen, hay fever, pet dander, and dust are some of the same factors for both, according to allergy data.

Others may get asthma as a result of an allergic reaction, which usually occurs as a result of a food or skin reaction.

#08. Gluten Sensitivity Is Found in 60% to 65% of Persons With Irritable Bowel Syndrome and Recurrent Headaches

Furthermore, the findings show that 20%–25% of people are identified with gluten⁵ sensitivity yet don't show any symptoms.

#09. Food Allergy Death Statistics in the UK Show That 1 in 800,000 Children Under the Age of 16 Die Each Year as a Result of a Food Allergy Reaction

According to research on children with food allergies, there is a tiny chance of death from deadly reactions.

According to UK allergy statistics, there are 13 million children under the age of 16 in the UK, with only eight of them dying from food allergies in the last ten years.

Allergies to milk were the cause of four of the deaths.

#10. Around 80% Of Infants With Food Allergies Will Develop a Tolerance by the Age of Five

According to global food allergy statistics, another 35% of these infants will develop hypersensitivity to certain foods in the future.

According to epidemiological studies, infants who are less likely to outgrow their food allergies have the most serious symptoms, such as asthma and anaphylaxis.

#11. Hay Fever Is Said To Be the Cause of 80% of Asthmatic Symptoms

Allergic rhinitis can make an asthmatic's already irritated airways enlarge even more, making breathing even more difficult.

Asthma episodes can be triggered by a variety of factors, including respiratory illnesses, strong scents, stress, and intense emotions, as well as pollution.

External factors, such as mold, can also trigger asthma.

#12. According to Cat Allergy Statistics, Approximately 10% Of People Are Allergic To Domestic Cats

Around one in seven children aged 6 to 19 has been found to be allergic to cats.

#13. Dogs Can Be Allergic to People

Experts say that canines can be sensitive to humans, and that the allergies usually appear as skin problems.

Canines are allergic to both human and cat dander, thus they can react to both.

#14. Globally, 10%–20% Of People Are Allergic to Dogs and Cats

In fact, statistics suggest that those who are allergic to these pets are more likely to suffer from asthma or other allergies.

Not only that, but cat allergies affect twice as many people as dog allergies do.

#15. Anaphylaxis Caused by Insect Stings Is Responsible For up to 100 Deaths Each Year

According to allergy statistics, approximately 3.3 percent of individuals get anaphylaxis after being stung by a bug like a bee or a mosquito.

Peanuts, milk, shellfish, and tree nuts are the most frequent food allergies in children.

Shellfish allergies affect the majority of children (8.2 million).

#25. Wheezing, Diarrhoea, Skin Rash, & Face Swelling Are the Most Frequent Food Allergy Symptoms

Anaphylaxis, on the other hand, is a severe allergic reaction that can occur in some persons.

Anaphylaxis symptoms can begin suddenly and deteriorate quickly.

Tachycardia, pouring eyes and nose, fast swelling of the lips, face, neck, and mouth, vomiting, and even loss of consciousness are some of the most typical symptoms.

#26. About 60% Of Urban Dwellers With Asthma Are Allergic to Cockroaches

Asthma patients with severe rhinitis are four to five times more likely than those without rhinitis to have poorly managed asthma.

#28. Food Allergies Can Be Inherited

If one of the parents or siblings has a food allergy, hay fever, asthma, or eczema, the infant is more likely to get one as well.

This, however, is not a given. Pollen, dust mites, cow's milk, eggs, and insects are among the most common inherited allergies.

According to food allergy facts, nursing can help prevent the development of food allergies in babies.

#29. The Frequency of Atopic Eczema Has Increased by 2-3 In the Last Two Decades

The incidence of Atopic Eczema has increased two to thrice in industrialized countries over the last three decades, with a lifetime frequency of 15-30% in children and 2-10% in adults.

#30. Aquagenic Urticaria Is an Uncommon Type of Allergy That Affects One Out of Every 23 Million People

Aquagenic urticaria is a type of allergic reaction to water that occurs when it comes into contact with the skin.

Remember that patients with this allergy can drink water, but they may experience an allergic reaction when showering, sweating, raining, or sobbing.

According to statistics on the incidence of worldwide food allergies, dairy sensitivity affects 2.5% of newborn babies.

The percentage of egg allergy is adjusted to 1.23% within the EuroPrevall birth grade.

#35. Seasonal Allergies Affect 24.4 Million People

Some people get allergies just in the spring, summer, or early fall, while others have them all year.

The distinction is in the causes of these problems.

Animals, dust mites, and insects produce perennial allergies, while pollen causes seasonal allergies. Mold can potentially cause both of these problems.

#36. Asthma Affects Around 339 Million Individuals Worldwide
