What are the symptoms of allergies?

Allergies are characterized by an abnormal immune response to typically harmless substances, leading to a variety of symptoms that can affect different parts of the body. The symptoms can range from mild to severe and may involve various organ systems.

Key Insights from Research Papers:

Allergic reactions can cause neuronally based symptoms such as red itchy eyes, sneezing, nasal congestion, rhinorrhea, coughing, bronchoconstriction, airway mucus secretion, dysphagia, altered gastrointestinal motility, and itchy swollen skin due to the interaction of mediators with sensory nerves and changes in the central nervous system.
Systemic manifestations of allergies in children include fatigue, irritability, pallor without anemia, infraorbital circles, nasal congestion, abdominal pain, and headache.
Allergic rhinitis symptoms often include sneezing, runny nose, itchy watery eyes, and fatigue, which can lead to sleep disruption and nasal obstruction.
Chronic respiratory symptoms associated with allergies include chronic cough, wheeze in the absence of colds, and allergic rhinitis, with the prevalence of these symptoms being influenced by factors such as smoking, allergen skin-test reactivity, and serum IgE levels.
General symptoms of an allergic reaction can include sneezing, running nose, congestion, watery and itchy eyes, wheezing, redness, and itching of the affected area.
In perennial allergic rhinitis (PAR), common nasal symptoms include itching and blocked nose, with the latter having the highest severity score.

Conclusion:

Allergies manifest through a diverse range of symptoms that can affect the respiratory system, skin, and gastrointestinal tract, among others. Common symptoms include sneezing, nasal congestion, itchy eyes, coughing, and skin irritation. Systemic effects such as fatigue and irritability are also noted, particularly in children. The severity and occurrence of these symptoms can be influenced by environmental factors, individual sensitivities, and coexisting conditions such as asthma.

Summary

Sources and full results

Mechanisms underlying the neuronal-based symptoms of allergy.

Allergen-induced neuromodulation alters sensory nerves, central nervous system, and autonomic nerves, leading to various neuronal-based symptoms in allergic reactions.

Systemic manifestations due to allergy. Report of fifty patients and a review of the literature on the subject (sometimes referred to as allergic toxemia and the allergic tension-fatigue syndrome).

Allergy can cause systemic manifestations in children, including fatigue, irritability, pallor, and various other symptoms, and should be considered in the differential diagnosis of generalized body symptoms.

Allergens, sources, particles, and molecules: Why do we make IgE responses?

Allergens are foreign proteins or glycoproteins that trigger IgE antibody responses in humans, with the relationship between exposure and allergic symptoms often being obvious or delayed.

A longitudinal study of respiratory symptoms in a community population sample. Correlations with smoking, allergen skin-test reactivity, and serum IgE.

Chronic cough is strongly correlated with smoking, while rhinitis is related to allergen skin reactivity, and wheeze is associated with both smoking and allergen skin reactivity.

What Is Allergy

Allergy is the abnormal immune response to substances that cause symptoms such as sneezing, running nose, and congestion, watery and itchy eyes, wheezing, redness and itching of the affected area.

Mechanisms of allergy and asthma.

Allergies and asthma are caused by inappropriate immune reactions to environmental proteins, with allergen-specific T helper cells playing a crucial role in the pathogenesis.

Seasonal Allergic Rhinitis

Seasonal allergies cause sneezing, runny nose, itchy watery eyes, fatigue, and sometimes shortness of breath, cough, and wheezing, often exacerbated by sleep disruption from nasal obstruction.

Allergy - Symptoms, Diagnosis, Treatment and Management

Allergies are the body's overreaction to harmless substances, such as pollen, causing symptoms such as inflammation, itching, and bronchospasm.

[Epidemiological characteristics, distribution of allergens, and symptom severity in patients with perennial allergic rhinitis, living in Konya region].

House dust mites are the most common allergens, itchy nose is the most common symptom, and blocked nose is the most severe symptom in perennial allergic rhinitis patients in Konya region.

Pediatric allergy: some impressions gained over a 37-year period.

Identifying and treating allergens is the most effective treatment for pediatric allergy, with food allergy being a common but often unrecognized cause of asthma, allergic rhinitis, and tension-fatigue syndrome.
