Food Allergy Rash

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.

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

There is no cure for a allergy rash caused by food 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.

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 adrenalin, 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.
