Allergies are immune system reactions to substances that are normally harmless. A variety of substances can cause allergic reactions, including plants, animals, insect bites, food, metals, chemicals and medications.
Symptoms
Allergy symptoms may be different for people of different ages.
Infants may experience many formula changes due to numerous intestinal problems, such as colic, diarrhea, constipation, excess spitting, and vomiting. In addition, they may show signs of an inability to sleep, irritability, recurrent ear infection, congested nose or chest, eczema, excessive drooling, and extreme perspiration.
Children may show signs of asthma, nose rubbing, headaches, leg aches, intestinal complaints (diarrhea, constipation), sudden mood and behavior changes (hyperactivity, fatigue, depression, irritability, aggression), or erratic infections.
Adults or adolescents may experience depression, irritability, aggression, and moodiness, easy crying, chronic asthma, hayfever or sinusitis, intestinal complaints (bloating, diarrhea, constipation, gas), bad breath, or hives.
Treating Allergies
Allergy testing can be conducted to determine the source of your allergies. Understanding your allergies can help you develop ways to avoid triggers, decrease reactions, and live better.
