Infant inhalant allergies can cause vomiting, crying, and poor growth.

Patient's question:

No

Doctor's answer:

Milk powder can cause allergies in some people, because the human body produces an immune response to resist the invasion of foreign substances. It's similar to how some people may be allergic to pollen. Certain substances in milk powder are foreign to the human body, triggering an immune response and causing allergies.
Common symptoms of allergies include: difficulty breathing, dizziness, vomiting, diarrhea, redness and rashes on the skin, fainting, and even life-threatening reactions. If a newborn has an allergic reaction to breast milk, it can be very dangerous.
If you suspect an allergy to milk powder, pay attention to any abnormal reactions after use, such as respiratory, digestive, or neurological symptoms. You can also dilute a small amount of milk powder, let it cool to body temperature, and apply it to thin, sensitive areas of the skin (e.g., behind the ear) to test for a reaction.
Give it a try. If you're still not sure, go to the hospital for a skin test to determine what you're allergic to. It's a harmless and beneficial step. Most general hospitals should be able to perform such tests.
If you have an allergic constitution or a weakened immune system, you need to be even more cautious!
