What Are the Symptoms of Protein Allergy in Babies? How to Cope with It?

A baby's allergy to protein occurs when certain substances in food enter the body and are mistakenly identified by the immune system as pathogens. The immune system then releases a special immunoglobulin E, which reacts with the food to produce certain chemical substances. This can lead to a series of allergic symptoms, such as indigestion, skin itching, redness and swelling, headache, diarrhea, asthma, sore throat, and more. Let's take a look at the symptoms of protein allergy in babies and what to do about it.

1. Gastrointestinal Issues: When a baby experiences protein allergy, the first organ system affected is the gastrointestinal tract. The inability to absorb protein can lead to symptoms such as nausea, vomiting, and loss of appetite. In severe cases, there may be symptoms of abdominal bloating and pain. Some babies with weaker constitutions may even experience gastrointestinal inflammation. Therefore, parents must take this seriously.

2. Skin Allergy Symptoms: Allergies, regardless of the source, often manifest visually on the skin. This is also true for protein allergies. If a baby experiences protein allergy, symptoms such as hives and itching may appear on the skin. Parents must be careful not to let the baby scratch and break the skin.

3. Nervous System Affected: Protein allergy in babies not only affects the gastrointestinal tract but can also impact the nervous system. Common symptoms include headache and dizziness. In severe cases of protein allergy, there may even be symptoms of respiratory difficulty or shock. Therefore, it is crucial not to underestimate this condition and to seek treatment at a reputable hospital promptly.

When a baby experiences nausea, diarrhea, vomiting, loss of appetite, abdominal bloating, and pain, these symptoms may be caused by protein allergy. Additionally, abnormal skin manifestations, such as itching, may also occur. In severe cases, protein allergy can even damage the gastrointestinal tract and affect intestinal function.

Babies' protein allergy is often closely related to the milk they consume. Therefore, it is recommended to switch to a less allergenic milk powder or a hydrolyzed protein formula to help alleviate the symptoms of protein allergy. As the baby grows older, this condition will naturally disappear.

If, after birth, a baby exhibits abnormal symptoms, especially skin issues, and topical medications do not provide relief but instead make the symptoms worse, it is likely related to the milk they are consuming. In such cases, trying a different type of milk powder may help the baby's skin recover faster.
