Introduction
Allergy is an overreaction of the immune system to substances that are normally harmless. These substances are called allergens. When a person comes in contact with an allergen, the immune system becomes hypersensitive and produces inflammatory chemicals such as histamine, leading to symptoms like sneezing, itching, rashes, swelling, and breathing issues.
Allergies can affect different organs of the body including the skin, respiratory tract, digestive system, and eyes. They may appear suddenly or develop slowly over time. Some allergies remain mild, while some can turn severe and life-threatening.

| Causes of Allergies |
Causes of Allergy
Allergy occurs when the immune system identifies a harmless substance as a dangerous invader. Several factors contribute to the development of allergies:
- Genetic (Family History): If parents have allergies, children have a higher risk.
- Weak Immune System: Low immunity increases sensitivity to allergens.
- Pollution and Chemicals: Increased exposure causes respiratory allergies.
- Modern Lifestyle: Increased hygiene reduces natural immunity.
- Weather Changes: Seasonal pollen increases allergic reactions.
- Food Additives: Artificial colors and preservatives may trigger reactions.
Risk Factors
Some people are naturally at higher risk of developing allergies:
- Children below 10 years
- People with asthma
- Those living in polluted cities
- People with eczema or sinus issues
- Individuals with weak immunity
Pathophysiology: What Happens Inside the Body?
When an allergen enters the body, the immune system reacts by producing IgE antibodies. These antibodies attach to mast cells. Upon repeated exposure, these mast cells release chemicals like histamine which cause allergic symptoms such as itching, swelling, runny nose, or breathing difficulty.

| Symptoms of Allergies |
Common Symptoms of Allergy
Symptoms vary depending on the type of allergy. Some common symptoms include:
- Sneezing
- Runny or blocked nose
- Watery, itchy eyes
- Skin rashes or red patches
- Itching of skin, eyes, nose, or throat
- Abdominal pain, vomiting (food allergy)
- Swelling of lips, eyelids, or face
- Breathing difficulty or wheezing
Severe Allergy: Anaphylaxis
Anaphylaxis is a medical emergency. It occurs when the allergic reaction becomes severe and affects multiple systems of the body. It may include:
- Severe swelling of throat
- Sudden drop in blood pressure
- Rapid heartbeat
- Dizziness or fainting
- Difficulty in breathing
Immediate medical attention is required. Anaphylaxis can be life-threatening if not treated quickly.
Diagnosis of Allergy
Doctors may use the following tests:
- Skin Prick Test
- Blood test (IgE levels)
- Patch test for skin allergies
- Elimination diet for food allergies
Prevention of Allergy
- Avoid known allergens
- Keep home dust-free
- Use air purifiers
- Avoid strong perfumes and chemicals
- Wash bedding frequently
- Keep pets clean if allergic to animal dander
Complications of Allergy
If allergies are not managed properly, they can lead to several complications. These complications may vary depending on the severity of the allergy and the duration of exposure to allergens. Some complications develop slowly over time, while others may occur suddenly.
- Chronic Sinusitis: Persistent nasal allergy can lead to sinus infections.
- Asthma: Allergy-triggered asthma can cause recurrent breathing problems.
- Ear Infections: Children with allergies often develop middle-ear infections.
- Sleep Problems: Nasal blockage can disturb sleep patterns.
- Skin Infections: Constant scratching of eczema can cause bacterial infections.
- Anaphylaxis: In severe cases, allergies may lead to life-threatening reactions.
