Hives are present in around 20 percent of cases of allergic reaction in babies. These are raised swellings which can occur on any part of the body, often disappearing and reappearing in different locations. Hives generally show up soon after eating the type of food that the child is sensitive to, but may occur up to a few hours later. Often lasting just one or two days, hives can persist for several weeks in more serious cases.
Eczema is present in around 35 percent of small children with food allergies, and the specific allergen they are sensitive to may prompt the eczema to appear or worsen. Medical name atopic dermatitis, eczema shows up as rough, itchy patches on the skin and a flare-up can persist for several weeks or even months.
The final type of skin reaction that your child may experience is called an ‘allergy ring’ and shows up as a reddened area around the anus. Treatment mainly consists of keeping the area clean, dry and open to the air as much as possible.
If your child is allergic to a food substance, you will have to isolate this from their diet for their wellbeing. Most food products are labelled to indicate the presence of common allergens such as wheat, eggs and nuts, so should help you to purchase wisely. Always contact your doctor about any suspected allergies, noting particularly ones that appear to be getting worse or are accompanied by additional symptoms such as vomiting. If your child has respiratory problems after eating or collapses, call an ambulance immediately.
