What is An Allergy?
An allergy occurs when a person’s immune system reacts to a substance in the environment that is harmful. For example, when you come across pollen, you might get an allergy due to the particles and reactions that take place inside the body.
In this article, we will delve into how allergies affect our bodies, explore their causes, symptoms, various types, and discuss effective preventive measures.
How Does Allergy Affect Our Body?
Let’s take an example of pollen, you have come across the pollen, and the tiny particles enter in your body through the nose. The immune system (which plays a major role in protecting the body from any bacteria) will eventually take the position and start its reaction with the allergen (a term used for a substance that causes allergy, in this case, pollen is an allergen).
When the allergen enters the body, the cells will react with the allergen and produces antibodies. These cells produce special chemical name histamine as a reaction. The chemical will react with the mast cells (white blood cells) and attract the allergen towards it like two opposite magnetic pole attracts each other. In this way, mast cells produce allergies in the body.
Causes of Allergy
An Allergy can cause by various factors, including our body’s response to some substances and environmental factors. To understand the allergy type and its treatment accordingly, we first need to know the causes of the allergy. This section can help to learn about the causes of allergies.
Some common causes of allergies are
- Pollen
- Animal dander
- Dust miles
- Bee sting
- Latex
Our immune system protects our body from harmful bacteria and germs. Also our body will respond immediately to fight against these harmful bacteria. Our genetics can also cause allergies and if our ancestors have a history of allergies, we might get infected with one.
Environmental factors such as pollen can also trigger allergic reactions in the body. So if you are living in a place nearby pollen fields, try to limit your outside activities.
Symptoms of Allergy
The symptoms of allergy vary from person to person. Although, it also depends on the type of allergy. Consult your doctor, examine your symptoms, and plan the treatment accordingly. Some symptoms of allergies are:
- Mild symptoms include rashes, itching, red eye, and watery eyes.
- Moderate symptoms like itchiness, swelling, and trouble breathing.
- Anaphylaxis is a serious allergy caused by insect stings or food poisoning. Symptoms include swelling, trouble breathing, issues in the throat, dizziness, and low blood pressure.
How Much Time Does It Take To Show Symptoms?
The Allergy reactions start when the allergen enters your body. It may take more or less time to show the symptoms of a response. According to the reaction time, the allergic reaction categories are:
- Immediate reaction
Symptoms appear just in a few seconds to minutes. Symptoms include difficulty breathing, swelling, low blood pressure, and shock.
- Cytotoxic
These Symptoms appear after minutes or hours—igE antibodies damage cells by activating the complement system of the immune system.
- Immune complex-mediated
Symptoms set in several hours. IgM and IgG antibodies react with allergens to form immunocomplexes (antigen-antibody-complexes)
- Delayed Hypersensitivity
Symptoms are set in hours to days. It is usually found in long-term infectious diseases.
Types Of Allergy
There are many types of allergy, depending upon the environmental factors and seasons per year. Here is the information about different types
- Drug Allergy: Some people are allergic to certain medicines. The number of affected people by drug allergies are in small number. A diagnosis of drug reaction usually based on the patient’s history and symptoms.
- Food allergy: Some people have different stigma of immune system and different skin nature. Foods like egg, milk and soybean are more likely to trigger allergic reactions for some people. Strawberry allergy is the most common type of food allergy.
- Insect allergy: Bees, ants and fire ants are the most common stinging insects that cause an allergic reaction.
- Pollen allergy: Pollen allergy is the most common type of allergy. Many people know pollen allergy as “hay fever”.
It is important to know and understand the types of allergy.
Prevention
Allergy can be prevented by different ways, some of them are
- Avoid the things which can harm you. For example, if you have a serious problem with pollen stay away from it.
- Track the record of yourself, what you eat, and where you have been, so in case you got an allergy in the future, you can know some of the past highlights of what you did.
- If you have an allergy take your medicines as doctor advice.
- Wear a mask, be moisturized, and always keep yourself clean and hygienic.
It is really important to completely avoid those things and limit your activity in those environment which can trigger your allergies.
Practical Tips for Allery Management
The plants and flowers are in full bloom in spring, and many of us suffer from worse kinds of allergies. The allergic reactions and symptoms vary from person to person. On the other hand, managing allergies is not a complicated process; we all can handle it.
The primary strategy is to understand the triggers and avoid them. When it comes to seasonal allergies, your preparation is essential. Before going outside, check the pollen percentage in the environment and keep the crucial things with you, i.e., sunglasses and a mask.
Additionally, keeping your home clean and dust-free can help to reduce indoor allergies. While consulting with your doctors and following the detailed plan, we can enjoy outdoor activities and live our life to the fullest.
Conclusion
An allergy occurs when a person’s immune system reacts to harmful environmental substances. When exposed to an allergen, the immune system generates antibodies, which cause the production of substances such as histamine, resulting in allergic symptoms. Allergies can range from minor to severe, including potentially fatal anaphylaxis.
The common symptoms of an allergic reaction include Respiratory problems, skin rashes, itching, and stomach pain. The time it takes for symptoms to occur varies on the type of allergic reaction, which can range from instant to delayed.
The causes of allergies include genetic predisposition and environmental exposure. Specific allergy identification improves successful management.
Common allergy types are food, pollen, insect sting, and medication allergies. Preventive methods include avoiding allergens, keeping track of triggers, taking prescribed medications, and practicing excellent hygiene.
