      Skin Allergy Caused By Food Allergy

      A food allergy is an adverse immune-mediated reaction to a specific food. Even a small amount of a particular food can cause skin rash, nausea, vomiting, cramping, and diarrhoea in someone with a food allergy. This allergic reaction is often referred to as hypersensitivity because the body reacts to something harmless. Anaphylaxis, or anaphylactic shock, is a potentially fatal reaction to a severe allergic reaction.

      Food allergies cause skin reactions after eating certain foods. The rash can be itchy and red, appearing on any body part. Food allergies result from an immune system reaction to a food protein that the body perceives as harmful.

      Food allergy rashes were estimated to affect 32 million people in 2021, including 5.6 million children.

      There are various types of food allergy rashes, each with its own symptoms. However, atopic dermatitis, also known as eczema, is the most common food allergy rash. Eczema is a chronic, inflammatory skin condition characterised by itchy, dry skin.

      Hives, also known as urticaria, can be caused by food allergies. Hives are raised welts that can be itchy or painful. They are frequently the result of an allergic reaction to food or medication. Contact dermatitis and angioedema are two less common food allergy rashes.

      Food allergies are common in children, and most of them resolve independently. Food allergies can occur later in life, but they are uncommon.

      Symptoms Of Food Allergies

      An allergic reaction to a specific food may be uncomfortable but not severe for some people. However, an allergic food reaction can be frightening and even life-threatening for others.

      11 Foods That May Cause Allergy

      Please remember that this is a list of foods to which some people may be allergic. It is not a list of foods to avoid unless you have a known allergy. Allergens differ from person to person and from food to food. However, if you notice someone developing severe symptoms after consuming these foods, take them seriously and seek medical attention if symptoms worsen.

      1. Soya beans and their Products- Soy protein allergy is extremely common in children. Itching, rashes, and raised reddish areas may result.

      2. Egg and egg products- Usually in children under 16. It is capable of causing stomach pain and itchy rashes.

      3. Peanuts and foods containing them- One of the most common and dangerous food allergies. Shortness of breath and excessive itching can occur.

      4. Cow milk and its derivatives- Whey and casein are important proteins in cow's milk. This usually manifests as tingling, itching around the mouth, and swelling.

      5. Wheat and wheat products- Wheat proteins such as globulin, gluten, albumin, and gliadin cause reactions in about 1% of people.

      6. Shellfish and its derivatives- Tropomyosin, a protein, can cause itching, hives, and skin rashes.

      7. Meat and meat products- In most cases, the allergy is to red meat sources, resulting in symptoms such as indigestion, stomach pain, and congestion.

      8. Raw fruits and vegetables- Fruits and vegetables contain allergic proteins that do not denature or break down when consumed raw.

      9. Histamine-containing food- Wine, fermented food, dry fruit, cheese etc

      10. Foods containing gluten- like wheat, barley etc.

      11. Fish and fish-related products- Allergic reactions are usually caused by the presence of parvalbumin proteins in them. This can cause itching, congestion, or stomach pain.

      Aside from these common allergenic foods, others can cause allergic reactions on your skin.

      Furthermore, suppose the protein in one food is similar to that in another food in the same category. In that case, it may cause an allergic reaction. This is referred to as cross-reactivity. For example, you may also be allergic to goat milk if you are allergic to cow’s milk because they contain the same proteins. Likewise, people who are allergic to latex are also likely to be allergic to fruits such as kiwi, avocado, and banana.

      Food allergies are typically diagnosed in early childhood. However, different blood and skin tests can be used later in life to identify allergens-causing reactions. Most people outgrow food allergies as they age, but they can last a lifetime.

      2. Why do I suddenly have skin allergies?

      3. Is skin allergy serious?

      The most common allergic skin conditions are allergic contact dermatitis (rash where an allergen touches the skin), atopic dermatitis (eczema), urticaria (hives), and angioedema (swelling). Hives and swelling often happen together and may suggest a severe and life-threatening allergic reaction.

      4. What are the 3 stages of an allergic reaction?

      These antibodies travel toward the cells that release histamine and other chemical mediators, which is why allergy symptoms start to occur. The human body carries out an allergic cascade in three stages: sensitisation, early-phase, and late-phase.
