How to Identify Symptoms of Formula Milk Allergy
Disease description:
Hello, Doctor. My baby has been feeling unwell lately, and I suspect it might be an allergy to formula milk. However, I'm not quite sure how to identify the symptoms of a formula allergy. Could you please explain it to me? This way, I can better assess my baby's condition, and if it is indeed an allergy, I can take prompt action. Thank you very much.

To identify symptoms of formula milk allergy, one can assess manifestations in the skin, gastrointestinal tract, and respiratory system.
1. Skin symptoms: Common skin manifestations of formula milk allergy include eczema, which typically appears shortly after exposure to formula milk. It initially presents as red patches, followed by development into dense small papules. In severe cases, there may be exudation and crusting, commonly affecting the face, neck, and extensor surfaces of the limbs. Urticaria (hives) may also occur, presenting as wheals of varying sizes and shapes accompanied by itching. Infants may become irritable and scratch their skin.
2. Gastrointestinal symptoms: Infants may refuse to feed or experience frequent spitting up due to gastrointestinal discomfort. Some infants may develop diarrhea with changes in stool consistency, such as watery or mucus-containing stools, and increased frequency. Others may develop constipation related to functional disturbances caused by intestinal allergy. Additionally, abdominal pain is common, and infants may cry persistently without an apparent cause and be difficult to comfort.
3. Respiratory symptoms: Symptoms may include runny nose and nasal congestion resembling a common cold but without other signs of infection such as fever. Coughing may also occur, usually as an irritating dry cough, and severe cases may lead to wheezing, particularly exacerbated at night or after physical activity.
If an infant develops the above symptoms after consuming formula milk and other common causes have been ruled out, formula milk allergy should be suspected. Prompt medical attention is necessary for relevant examinations to confirm diagnosis, and feeding strategies should be adjusted under medical guidance.
