Identifying allergies in infants can be challenging because the symptoms are similar to that of the common cold, according to the Baby Center. Allergies are confirmed in infants by seeing a pediatrician. Common allergies in children include airborne allergens, food allergies and skin allergies. An infant experiences an allergic reaction when her immune system mistakes a substance as harmful. The infant's immune system builds intolerance toward the allergen that causes irritation in the body, leading to common allergy symptoms.
Identification
Identifying allergies in infants begins with knowing what symptoms to look for, according to the Baby Center. Some common symptoms pointing toward an allergy are constant cold-like symptoms, a stuffy nose, a constant wiggling or wiping of the nose, excessive sneezing, fussiness, mouth-breathing or a dry cough. If a skin rash develops or the child has diarrhea or vomits after eating certain foods, she may have a food allergy, according to KidsHealth.
About Airborne Allergens
Airborne allergens are common among infants, especially if the child's parents have a history of allergies or asthma. Airborne allergens are typically caused by pollen, dust mites, mold and pet dander, according to Dr.Greene.com. Airborne allergens are avoidable by maintaining a clean home, running an air purifier, remaining indoors during springtime and eliminating visible mold around the house.
Food Allergy Consideration
A dairy allergy may be the first sign of a food allergy in infants, according to KidsHealth. When an infant has a food allergy, her immune system recognizes proteins in certain foods as hazardous. The most common foods causing allergic reactions in infants are dairy products, nuts and eggs. An infant with a food allergy will show symptoms such as diarrhea, vomiting or continual fussiness. A food allergy may cause swelling in the face, tongue or throat and could be potentially life-threatening. Seek immediate medical advice if swelling develops.
Eczema Consideration
Dr.Greene.com states that eczema is a common allergic skin condition that is triggered by allergens and dry skin. Eczema produces itchy welts throughout the body of the infant. If the infant is exposed to allergens, the body produces histamines that irritates the skin. If eczema goes untreated, it can leave permanent scarring. Prevent eczema outbreaks by keeping the skin moistened, avoiding allergens and treating the affected spots promptly with hydrocortisone.
Warning
The Baby Center states that a severe allergic reaction in an infant can lead to a life-threatening condition, called anaphylactic shock. Anaphylactic shock is a rare allergic reaction that affects the entire body. If an infant becomes unconscious or does not respond to stimuli, get immediate medical attention.
