Food Allergies: An Insight into the Causes, Symptoms and Management

Millions of people worldwide have food allergies and these conditions can be life-threatening or even cause death, especially if the allergic reactions are severe. The immune system is responsible for protecting the body against harmful substances, but when someone has a food allergy their immune response to proteins in certain foods are triggered even though they are wrongfully identified as threats. For this reason, the reactions can be anything from slight discomfort to serious life-threatening things such as anaphylaxis. In this detailed guide, we are going to give you a walk-through of food allergies — what they are and the common symptoms associated with them, as well as the types & causes for these kind of irritations till how do you soothe & treat it.

What is a Food Allergy?

Food Allergy: When the immune system of our body overreacts to protein from certain foods it is known as a food allergy. Where food intolerance is related to the digestive process, allergies affect our immune system and may have severe health implications. Just a trace of the food that triggers an allergic reaction can be sufficient to bring on life-threatening consequences, which is why those who have good allergy dietinternet allergies need to pay close attention to what they eat. Food allergies are most common in children, but can appear at any age.

Significant Food Allergy Symptoms:

• Itching in your ears, mouth or throat
• Urticaria (Hives or raised itchy red rash)
• Hives; difficult breathing, swelling of your face, lips,tongue or throat (angioedema)
• Vomiting, nasea and stomach cramps
• Shortness of breath, difficulty breathing or wheezing or cough.
• Dizziness or lightheadedness
• In severe cases, anaphylaxis

Most Severe Reaction: Anaphylaxis

Anaphylaxis is an immediate, severe allergic reaction that can rapidly occur following ingestion of a food causing the allergy. It pertains to many other systems in the body such as respiratory, cardiovascular and gastrointestinal system. If anaphylaxes occur, then the decisive factor is immediate medical treatment to avoid that this causes fatal.

 

Signs of Anaphylaxis:

• Lack of air in the lungs because with small tubes止
• Difficulty swallowing or breathing (Symbol: ABC)
• Shock (sudden drop in blood pressure)
• Rapid or weak pulse
• Collapse or loss of consciousness

For anaphylaxis, use an auto-injector such as that in the EpiPen. For those with a known food allergy or for someone who knows you to have an EpiPen available can quite Litteraly be the difference between life and death.

What are 10 common food allergies?

While virtually any food has potential to cause an allergic reaction, there are certain foods that top the list for causing most of them. Examples of common allergens include:

• Milk
• Eggs
• Peanuts
• Walnuts, almonds and other tree nuts
• Fish
• Shellfish
• Peanuts
• Tree nuts
• Fish and shellfish
• Produce (Apples, peaches…)

The New Addition of Sesame as the 9th Top Food Allergen makes a point about being sure to spot patterns in food possibilities relating how allergies are changing. Note: Sesame is usually present in stuff like tahini and hummus, though it will not always be obviously labeled.

 

The Causes and Risk Factors of Food Allergies

During an allergic reaction, the immune system incorrectly identifies proteins in food as harmful and releases chemicals such as histamines that cause symptoms of an allergy. Challenge factors The most important is thinking about the challenge aspect of food allergies,

 

• Heredity: Like many medical allergies, food allergy is hereditary. You should also avoid irritants where children have a family history of allergic, or likely to occur allergies.
• Having Other Allergic Conditions: People with asthma, eczema or hay fever may develop certain food allergies.
• Introduce allergenic foods early: The introduction of allergenic food in infancy either increases or reduces the risk for developing allergy to that respective food, depending on genetic factors.

In some cases, environmental factors such as pollutants or a diet lacking in certain nutrients may also be involved.

Types of Food Allergies

Food allergies depend on how the body reacts, and there are three main types:

• IgE-Mediated Food Allergy: To fall into this category, the body must produce IgE antibodies in response to an allergen which triggers immediate symptoms when eaten. This type has an increased incidence of anaphylaxis.
• Non-IgE-Mediated Food Allergy : Symptoms are caused by other parts of the immune system, not IgE antibody; these reactions usually get difference long time before occurred.
• Mixed IgE and Non-IgE-Mediated Food Allergy: In some cases, people have both types of reactions.

Another is called Oral Allergy Syndrome (commonly referred to also as Pollen-Food Syndrome) where someone feels itchiness, and sometimes mild swelling of the mouth or throat after consuming specific fresh fruits, vegetables or nuts. It happens because proteins in the food are similar to pollen allergens.

 

Diagnosing Food Allergies

Determining whether or not you have a food allergy can be difficult, but it is essential in controlling the disease. If you think that you have a food allergy, it is important to see a doctor and/or allergist so they can run more specific tests. Diagnosis as with other diseases consisted of:

• Skin Prick Test: This test involves placing a small amount of the suspected allergen on one's skin; if it develops into an elevated bump, then there may be evidence that you are allergic to this substance.
• Blood Test : This is a blood test that helps to analyze the number of IgE antibodies in response to certain foods.
• An oral food challenge is a test performed under direct medical supervision where the patient eats small amounts of an allergen at determined intervals to determine if they have any reaction.
• Do not use commercial allergy testing kits, because they can be inaccurate. Always seek a professional diagnosis
• Living with a Food Allergy
• While there are life-threatening risks associated with food allergies, appropriate measures and vigilance can make living with a food allergy manageable. Managing Food Allergies: Some Key Tips
• Check Food Labels: Be sure to read ingredient lists carefully, including items you have bought previously in case ingredients can alter.
• Prevent Cross-Contamination: Keep separate utensils, cutting boards and pots for your allergen-free meals.
• Speak Up: Mealtime at restaurants or social events provides a perfect opportunity to let people know about your food allergy.

Anaphylaxis is a life-threatening situation and everyone who has serious allergy reactions should carry adrenaline auto-injector, and people around them should be able to use such for emergency situations.

Treatment for Food Allergies

Food allergies at present have no cure. The best way to avoid having an allergic reaction is not eating the allergenic food at all. Nevertheless, desensitization therapies are being developed for other allergies such as peanuts and milk which involve progressively introducing tiny amounts of the allergen to increase tolerance.

In the case of mild to moderate reactions, like itching or swelling, antihistamines can ease symptoms. Epinephrine may be the only way to combat anaphylaxis, especially in severe cases.

 

Conclusion

Food allergies are a scary reality millions of people all around the world face every day, sometimes causing mild discomfort and in others leading to life-threatening anaphylaxis. Therefore, it is important to be informed about the possible causes of food allergies as well as their symptoms and types so that you can better manage them. If someone from the UK or America, for example is diagnosed with shellfish intolerance they will go into this much faster and trying harder not to be exposed than in Cyprus. Living with a food allergy is manageable, however, only when proper care and medical support have been instituted; in addition research maintains ongoing work toward the likely availability of increased treatment choices within the future.
