Essay on Allergies and Allergic Reactions

Anaphylaxis is an extreme and sever allergic reaction that can be caused by insects bites, foods, latex and medication. This allergic reaction fiffers from one person tp the other. In some people, it can only affect one part of the body whereas in others, it affect more than one part of the body. The effects are usually within a few minutes of exposure to the substance that causes the allergic reaction. In other instances it can take hours before the effects are seen. This allergic reaction calls for immediate medical treatment because it can be fatal id it is not treated properly.

It was a sweltering July day and suddenly I had an incredible pain in my stomach. It felt as if the acidic gases in my stomach were churning up and down, burning the inside of my stomach. My mom frantically dialed 911 and I swiftly arrived at the hospital in an ambulance. Not long after I arrived, the doctor notified me I was having an allergic reaction.

An anaphylactic reaction (anaphylaxis) is a sudden, severe allergic reaction that affects multiple areas of the body. Affected areas of the body may include the skin, mouth, lungs, heart, or gut (digestive system). Anaphylaxis can be life-threatening. This condition requires immediate medical attention, and sometimes hospitalization.

B.J.was exposed to cats, thus causing an acute asthma attack. Patient being exposed to cat fur is what caused his allergic reaction. IgE antibodies cause allergic reactions, these cells are mainly attached to mast cells that lie in the lung interstitium in close association with the bronchioles and small bronchi. Once BJ breathes in the fur, to which he is sensitive to, the pollen reacts with these mast cells and thus causing these cells to release histamine. Which causes localized edema in the bronchioles as well as thick mucus. This causes the spams in the bronchilar smooth muscle which cause airway resistance. In return causing an acute asthma attack.

With just a very quick exposure to an allergen, anaphylaxis can occur immediately. Allergens can be anything from dust, food products such as peanuts, shellfish, nuts, and even insects and sting like bees and wasp stings. Life threatening symptoms of anaphylaxis include dizziness, unconsciousness, shortness of breath, difficulty breathing, and fast heart beat. The most serious threat to the human life during anaphylaxis is the lack of oxygen, O2. With lack of O2 the brain begins to lose brain cells. The brain is in control of all the systems in the body as more time passes without O2 organs begin to fail and the heart also stops beating.4 Other symptoms of swelling of the mouth, coughing, hives on the body, vomiting, and

The ironic thing about allergens is that most aren’t harmful to the body, but this doesn’t stop the immune system for mistaking them for foreign bodies, which is why it decides to fight back. Our immune systems are amazing things. They create proteins to fight disease, which are known as antibodies. These antibodies try to battle it out against the antigens. Once our immune system creates certain antibodies, they’ll recognize the same intruders again and protect our bodies automatically year in year

Susceptible Individuals are at risk to curtain airborne allergens and things that trigger frequent attack. According to Barnes, (2003) allergic reaction comes from factors, such as allergens, viral infections and exercise .Other triggers such as family pets, which includes dogs, cats and hamsters can cause an allergic reaction. Smoking, dust and fumes plays a part in the environmental factors. Asthma symptoms include tightness and cough chest, wheeze and breathlessness. Airflow obstruction results from twitchiness of the muscles in the airways and inflammation resulting in swelling of the airway walls as well as accumulation of secretions (Asthma UK, 2014) over time symptoms might vary. In young children symptoms in the severity

Anaphylaxis is accompanied by drops in blood pressure, excessive swelling, hives, and dilated blood vessels. Many times when anaphylaxis happens, the body goes into shock, which is where the term anaphylactic shock comes in. Anaphylaxis occurs when your immune system develops immunoglobulin E which is a specific antibody that is meant to fight allergens. However, this antibody causes exaggerated allergic reactions towards the allergen. Symptoms don’t always present immediately but when they do it is crucial that they are treated

Allergies are very common and global chronic diseases which occurs when the people’s immune system overreacts a substance which is judged to be harmful to human body. It’s now becoming major public health problem in developed countries especially in Australia. In 2007, according to an ASCIA-Access Economics Report that 4.1 million Australians (19.6% of the population) had at least one allergic disease. Also specialists speculate if Australia’s ageing trend continues, there will be a 70% increase in the number of Australians with allergy, from 4.1 million in 2007 to 7.68 million by 2050 (26.1% of the population). In this article, three aspects which related to allergies in Australia will be discussed in turn: causes, symptoms

Allergic Asthma or allergy-induced asthma is one of many forms of asthma. Asthma is a chronic lung condition that results in recurring episodes of a difficult problem breathing. According to Asthma and Allergy Foundation of America(aafa), about 25 million Americans have some form of asthma. Breathing is a basic essential part of life which is normally done without thinking about it. The people with asthma airway may become inflamed and constricted due to allergens, irritants, physical activities and/or respiratory infection. The symptoms of this chronic condition may vary in the individual person. Some symptoms are coughing, wheezing, shortness of breath, and chest tightness.

The first step is to identify the source of your allergy. Be aware of your allergic reactions and identify the allergens present at your workplace that can trigger these symptoms. Dust and mold are the most common workplace allergens.

Anaphylaxis is the serious allergic reaction that affecting multiple organ systems. It is rapid in onset and can cause sudden death (ASCIA 2016). It can occur within minutes to hours. Vasovagal episode is usually common following the vaccination in adult but in children fainting can occur rarely. Anaphylaxis is characterised by circulatory collapse and respiratory distress. Immediate skin symptoms include pruritus, generalised skin redness, urticaria, angioedema whereas gastrointestinal sign and symptoms such as vomiting, diarrhoea and abdominal pain/discomfort (SA Health 2016). Severe cardiovascular symptoms involves weak/absent carotid pulse, hypotension, tachycardia, loss of consciousness with no improvement through head down position, circulatory collapse, which is manifested by, airway obstruction, confusion, bronchospasm, swollen face, tongue, throat, wheezing/coughing, hoarseness, stridor (ATGI 2016).

Allergic rhinitis is started by an allergic immune response to inhaled allergens. Atopic people have a genetic predisposition to become sensitised to harmless allergens. Dendritic cells which act as antigen-presenting cells capture the allergen and present allergenic peptide to T lymphocytes in lymph nodes. CD4+ T cells play an important role in starting and orchestration of the allergic immune response by secretion of cytokines such as interleukins 4, 5, 10, and 13. Interleukin 4 is fundamental cytokine in driving sensitisation to allergens. Interleukin 4 stimulatesthe IgE switch in B lymphocytes. After releasing of IgE into the bloodstream it binds to receptors on the surface of mast cells and basophils. When the patient exposure to the allergen and the allergen reach nasal mucosa of sensitised individuals, they bind allergen-specific IgE on the surface of mast cells, resulting in release of inflammatory mediators such as histamine.

Allergies are among the most common inveterate case worldwide. Allergy symptoms range from making you powerless to putting you at risk for life-menacing reaction.Food allergies are defined as “ the body 's abnormal responses to harmless foods; the reactions are caused by the immune system 'sreaction to some food proteins” (thefreedictionary.difntion.com).In other words,The job of the body’s immune system is to identify and ruin germs (such as bacteria or viruses) that make you sick. A food allergy results when the immune system wrong targets a harmless food protein an allergen as menace and attacks it.

Symptoms of a food allergies can often include wheezing and difficulty in breathing, along with itchy skin rashes, including hives, vomiting, diarrhea, nausea, abdominal pain and swelling around the mouth and in the throat (common with nut allergies). These symptoms usually develop fairly quickly after a child ingests the food that they are allergic to,
