We are here to share what we have learned. Our group would like to help you gain a brief and concise information regarding Allergies.😊❤️
💡DESCRIPTION
📌 Allergy occurs when a person reacts to substances in the environment that are harmless to most people. These substances are known as allergens and are found in dust mites, pets, pollen, insects, ticks, moulds, foods and some medications.
💡HISTORY

Standing in park in warm clothing.Though allergic reactions have been documented in ancient Greek and Roman history, the modern era of the study of allergies really began in the 1800’s when hay fever was described by Dr. John Bostock in 1819. This continues to be one of the most common allergic reactions, affecting approximately 15 million people in the United States.
📌In 1869 the first skin test for allergies was described when a scientist placed pollen into a small cut in the skin and watched for a reaction.
📌The concept of immunotherapy, which is building up the immune system through the administration of injections to help people cope with their allergies, was introduced in 1914.
📌Antihistamines, medications that would help the body respond better to allergic reactions became more widely used in the late 1930’s. They helped by lessening the body’s reaction to allergens.
📌In 1948 corticosteroids were first used to treat asthma and allergic reactions. They worked on reducing the inflammation that would be caused by the allergens.
💡CLASSIFICATIONS & TYPES
📌Types of allergy are classified to denote cause, severity and possible management and prevention. These include –
📌Type I hypersensitivity
This is also known as immediate or anaphylactic-type reactions. This may be caused due to pollen, foods and drugs and insect stings.
📌 Type II hypersensitivity
This involves specific antibodies called the Immunoglobulin G (IgG) and IgM. There is binding to and destroying the cell the antibody is bound on. This type of reaction is seen after an organ transplant when the body refuses to see the transplanted organ as its own.
📌 Type III hypersensitivity
This is an Immune complex-mediated reaction. The immune complex is the bound form of an antibody and an antigen. This leads to a cascade of reactions in the body which goes on to destroy local tissues. Examples of this condition include glomerulonephritis and systemic lupus erythematous (lupus, SLE).
📌 Type IV hypersensitivity
Delayed or cell-mediated reactions are mediated by special immune cells called the T-cell lymphocytes. The T cells take from a few hours to a few days to mount an allergic response. Examples include contact dermatitises such as poison ivy rashes.
💡FACTORS CONTRIBUTING TO EMERGENCY
📌If you're with someone having an allergic reaction with signs of anaphylaxis: Immediately call 911 or your local medical emergency number. Ask the person if he or she is carrying an epinephrine autoinjector (EpiPen, Auvi-Q, others) to treat an allergic attack.
💡PREVENTIVE MEASURES
📌 Controlling your allergies and preventing allergic reactions depends on your type of allergy. Here are some ways to manage your allergies:

📌Take your medicines as prescribed.
📌 If you are at risk for anaphylaxis, keep your epinephrine auto-injectors with you at all times.
📌Keep a diary.
📌 Know what to do during an allergic reaction.
💡FIRST AID MEASURES
If you’re with someone who’s experiencing anaphylaxis, you should:
• Call 911 immediately.
• See if they have an epinephrine (adrenaline) auto-injector (EpiPen) and help them, if needed.
• Try to keep the person calm.
• Help the person lie on their back.
• Raise their feet about 12 inches and cover them with a blanket.
• Turn them on their side if they’re vomiting or bleeding.
• Make sure their clothing is loose so they can breathe.
• Avoid giving oral medications, anything to drink, or lifting their head, especially if they’re having trouble breathing.
💡CONCLUSION
We firmly believe that allergy is a very common in the human population. This may not seem as serious as you think it is but it can be very fatal if we don't know how to deal with it. The things that we must to do is to avoid yourself what triggers your allergies. Now, although this is common, this can still be modifiable just simply follow the proper care and preventive measures. As how the saying goes "PREVENTION IS BETTER THAN CURE". We believe that discipline must be the governing principles of each individual. Let us be responsible individuals and live life in moderation.
