Why Do Certain Foods Trigger Allergic Reaction
Allergic reactions to certain foods occur when your immune system reacts to the protein found in that specific food item. Your immune system considers it as a pathogen and tries to attack it. Naturally, your body reacts to the attack, which leads to the development of skin rashes. In some cases, allergic reactions can get severe and even turn into a life threat .
You may develop a rash shortly after eating a food that you are allergic to. You may get it on your mouth, face and neck. But in some cases, you may develop allergic rashes just from touching the food item. The symptoms of food allergy rashes are mostly the same for both adults and children. Only in a few rare cases, symptoms might be different.
Home Remedies For Skin Rash
Although avoiding contact with pollen will prevent you from developing a seasonal allergies skin rash, this is not always a viable option. However, there are several home remedies you can try and apply to irritated areas of skin to try to ease your symptoms.
Often keeping the affected area of skin cool helps to soothe irritation and heals the rash more quickly. Clay poultices, such as bentonite clay, can sometimes help skin problems, although you should be careful that these poultices are natural, as any chemical ingredient will only worsen your condition.
Oatmeal can also be effective in easing skin rashes as it has anti-inflammatory properties. It can be made into a paste by mixing a little water with some uncooked oatmeal, which can then be directly applied to the skin.
Lemon has also been used to treat itchy skin, as it has strong anti-inflammatory and antiseptic properties. However, it may sting a little when initially applied, particularly so if the skin is broken.
Aloe vera gel, peppermint or basil leaves applied directly to the skin are also traditionally used to ease skin problems, as they have a soothing effect on the skin by reducing itching and inflammation.

Chronic Urticaria Is Defined When Hives Occur Most Days For More Than Six Weeks
Symptoms of chronic urticaria usually resolve, although this can take months or several years. Most people with chronic urticaria manage with appropriate doses of non-drowsy antihistamines. People with severe symptoms interfering with quality of life may be referred to a clinical immunology/allergy specialist or dermatologist for assessment and consideration of additional medications.
Patients With A Normal Primary Survey With Obvious Need For Hospital Admission
The following conditions may present initially with a normal primary survey but immediate treatment and hospital admission should be initiated:
Suspected rash of meningococcal septicaemia
Definite exposure to a trigger that has previously lead to an anaphylactic reaction
Self administration of adrenaline by a patient for a suspected anaphylactic reaction
A suspected anaphylactic reaction that has not fully developed
Cellulitispatient clinically toxic or affecting the peri-orbital tissues
The history and findings on examination should help to establish whether you are faced with such a scenario. Although these patients may not have abnormal clinical signs at the time of assessment, this should not lull you into a false sense of security as they may deteriorate rapidly. In the case of suspected meningococcal septicaemia, early administration of appropriate antibiotic therapy is safe and associated with an improved prognosis. Whenever there is a suspicion of anaphylaxis, adrenaline for intramuscular injection should be readily available. If the above situations present, based on the history and examination findings as described in this article, then appropriate treatment should be administered and hospital admission arranged.

An Introduction To Skin Rash And Seasonal Allergies
Skin rash is a very under-publicised symptom of seasonal allergies. Although it does not affect all seasonal allergies sufferers, it can be extremely irritating for those who do experience it.
Common symptoms of seasonal allergies, such as congestion or itchy eyes, occur when pollen is inhaled, triggering a reaction in these tissues. However, some people also react to pollen landing on their skin. This reaction can result in localised itching which may develop into a rash.
Although not as common, some people also develop hives on their skin from seasonal allergies, which are small bumps which turn white when pressed.
In addition, some people can suffer from seasonal allergies, asthma as well as eczema a triad of conditions which doctors refer to as the atopic triad.

Anaphylaxis And Anaphylactoid Reactions
Management plan1. Admit and treat immediately
Anaphylaxis refers to a severe generalised allergic reaction, whereby specific triggers stimulate the release of IgE immunoglobulin. This IgE release causes vasodilatation, airway swelling, and capillary leakage leading to hypotension. An anaphylactoid reaction results in an identical situation, but does not entail the release of IgE. An example of this is the reaction that can be seen to radiography dye. While no universally accepted definition exists, a good working definition is a severe allergic reaction to any stimulus, having sudden onset and generally lasting less than 24 hours, involving one or more body systems and producing one or more symptoms such as hives, flushing, itching, angio-oedema, stridor, wheezing, shortness of breath, vomiting, diarrhoea or shock. The rate of anaphylaxis in the UK has risen from 6 per million in 1990/91 to 41 per million in 2000/01.

In severe cases, a short course of steroid tablets or creams is prescribed to reduce inflammation of the skin. In some people, and if used incorrectly, steroid creams may result in side-effects so if you are using these medicines, please follow the instructions issued carefully.

What Is Sun Allergy
A sun allergy most often presents as itchy reddish spots or welts that usually develop within minutes of sun exposure. This condition can last for a few minutes to hours. These sun allergies are triggered by the changes that occur in the sun-exposed skin. However, the immune system considers some components of the sun-altered skin as foreign bodies and activates our immune defenses against them, producing an allergic reaction that takes the form of a rash, tiny blisters, or skin eruptions.

What Is The Best Way To Avoid An Allergic Skin Rash
The best thing you can do to prevent an allergic rash is to avoid contact with the allergen or irritant that causes the skin irritation.

When Is An Allergy
The emergency signs depend on the reaction youre experiencing. In the case of a food allergy, your non-skin symptoms will yield bigger red flags than the actual rash. These symptoms can include difficulty breathing, and in some cases, anaphylaxis. This is a life-threatening reaction that needs medical assistance ASAP. That being said, according to the U.S. National Library of Medicine, you should seek emergency help if you have:
- Inflamed streaks
To prevent infection, youll want to visit a doctor if your rash is persistent, painful, or severe. The same goes if you have multiple blisters that arent responding to home remedies like over-the-counter 1% hydrocortisone cream, Dr. Lighvani says.
Food Allergy Rash Vs Food Intolerance
A food allergy occurs when your immune system adversely reacts to proteins in a certain food youre allergic to. This is not the same thing as a food intolerance.
Food intolerance is primarily a digestive issue that can cause symptoms similar to food allergies, except that its not life-threatening.
Non-itchy rashes from a food intolerance can also develop over time, such as chicken skin on arms. This is unlike a food allergy rash, which tends to occur within minutes or hours of eating the suspected food. Food intolerance can also cause bloating, stomach pain, and mild digestive upset.
Another key difference is that you can sometimes have small amounts of a food without a problem if you have an intolerance. With an allergy, even a small amount of the food can cause issues.
According to the AAAAI, most suspected cases of food allergies are actually intolerances. However, you dont want to take a chance with self-diagnosis. An allergist can help you determine the difference.

Why Do Allergic Reactions Sometimes Manifest As Skin Rashes
Heres the thing: The link between allergies and skin rashes depends on the type of allergic reaction youre dealing with. Different allergens cause symptoms in different ways.
Sometimes, allergy-induced skin rashes are caused by eating certain foods, Benjamin Ungar, MD, assistant professor of dermatology at the Icahn School of Medicine at Mount Sinai, tells SELF. This involves a classic immediate allergic reaction.
A quick explainer: Your immune systems job is to protect you from potentially harmful microorganisms its your bodys first line of defense. But sometimes, those immune cells mistake typically benign substances, like food, as a threat. This sparks a false alarm, causing those cells to attack the invaders and produce antibodies called immunoglobulin , according to the American Academy of Allergy Asthma & Immunology . These antibodies trigger the release of chemicals, one of which is called histamine, causing allergy symptoms that develop soon after eating the offending food, according to a 2021 study published in Cells.1 Histamine can affect many areas of the body, including the lungs, digestive tract, heart, and skin. Most people with food allergies will experience multiple symptoms, but when hives are involved , its because histamine is released in the skin cells, which triggers a chain reaction that ultimately ends with inflammation and swelling.
