Food Allergy Rash

Visit this

A food allergy rash is quite common. People with food allergies can suffer minor symptoms such as a mild skin rash or the reaction can be more severe. In more serious cases, the symptoms are much more dramatic and life threatening.

The major concern with a food allergy and a food allergy rash is when these symptoms are a sign of a more severe allergic reaction. Generally, if the reaction is mild, the only thing the individual may experience is some mild discomfort or a slight skin rash that does not produce any other symptoms.

Severe Food Allergy Rash Symptoms

itchy hives or welts or rash on body caused by a food allergy rash

However, if the reaction is severe, there are certain characteristic symptoms to note. When coming in contact with a food allergen, the allergic symptoms can progress from mild to severe in a short amount of time. Typical symptoms of a more severe food allergy are:

  • an itchy and red food allergy rash or hives all over the body
  • a flushed face
  • swelling in the facial areas including the eyes, lips, tongue, and throat
  • stomach discomfort in the form of cramps, diarrhoea, or even vomiting
  • weakness, panic, and anxiety
  • breathing problems, inability to speak or swallow properly
  • rapid heart beat, drop in blood pressure, and loss of consciousness

Prevention of Allergic Rash Caused by Food

There is no cure for a food allergy rash or a food allergy. Prevention is critical. This includes undergoing regular allergy tests to establish sensitivity to foods. If a food allergy has been established, then avoidance of the offending food and derivatives of the food is a must. Careful ingredient label reading and sometimes additional literature research is required. This may include contacting the manufacturer of the product to ensure the food is safe to consume.

Cross-contamination, or in other words foods that have come in contact with each other, can lead to non offending foods causing an allergic reaction. This should always be considered when eating. In all cases, when in doubt, it is best to not eat the food.

Food Allergic Reaction Treatment

If a severe food allergy has been diagnosed, then it is imperative to carry at all times an adrenaline auto injector in case of anaphylactic shock. With any sign of a severe reaction or after use of the adrenaline, a visit to the emergency room is imperative and there should be no delays in going to the hospital. The rash and other symptoms may reoccur after a short amount of time (15 to 20 minutes) even after the adrenaline injection. Sometimes, a second injection can be given if symptoms reappear. This should be discussed with your doctor. On long trips, consider carrying two injectors, in case emergency help is further than 20 minutes away.

Common Foods that Cause an Allergic Reaction

Certain foods are more likely than others to cause a skin rash and other allergic symptoms. The nine foods most likely to cause an allergic reaction in no particular order are:





sesame seeds



tree nut

Food Allergies and Rashes

by Anonymous 

I have been recently diagnosed with food allergies and food sensitivities. The list of foods that cause me problems is long: dairy products, eggs, wheat/gluten, yeast (brewers and baking), spinach, banana, pineapple, corn, and mushrooms to name the big ones.

At one point, I began to get itchy hands and legs, swelling in my face and generally feel physically ill. Since stopping eating the problematic foods, but it is hard to do so, my face is better but my legs and hands still swell. Both my legs and hands turn bright red, are dry and itchy and tingle like needles are poking these areas everywhere all at once. I cannot walk or do anything when this happens. At my worst with these food allergies, I had a food allergy rash of white little blisters on top of the skin rash.

I was getting better (my asthma and seasonal allergy symptoms improved) after seeing a naturopath and my regular doctor, and I was ready to return to work but unfortunately a recent flare up of my symptoms is so much worse than ever before! I am very frustrated and unhappy with these food allergies causing my skin condition. I have not strayed from my clean diet and juicing. Most packaged foods even if listed gluten free or egg and dairy free still have corn or say "processed in a facility that processes..." something I cannot eat. When I gamble most times and try these foods I lose and the food allergy kicks in!

I am waiting to see the endocrinologist because I also have low thyroid but this appointment is still a month away.
