Formula Allergy in Babies- Causes, Signs, and Treatment

Difference Between Formula Intolerance and Formula Allergy

Formula allergy and formula intolerance are not the same as many mothers think. here is the difference between the two:

Formula Intolerance

The digestive system of the baby cannot tolerate the formula milk or digest it effectively. Due to this tolerance, the baby ends up having gastric issues. The intolerance is due to over-sensitivity or deficiency of a component that is present in the formula. Formula intolerance happens due to a defective digestive system and does not involve the immune system.

Formula Allergy

This type of milk intolerance involves the immune system where the antibodies attack the milk proteins thinking that they are pathogens. This in turn results in allergies and causes rashes, swelling etc. Formula allergy is more acute and fatal than formula intolerance.

What Causes Formula Allergy in Infants?

When the body is oversensitive towards the formula and shows a non-suitable reaction, formula allergy can be seen in babies. The allergy triggers when the immune system mistakes the proteins in the formula for foreign entities and attacks them.

This results in rashes, swelling, itchiness, etc. The allergy can differ in its intensity from one baby to the other. Many factors are responsible for causing a formula allergy in babies.

• The baby formula allergy can greatly be influenced by heredity, which means if the parents are allergic to anything, there are higher chances of the baby reacting towards it as well.
• The other main cause is a cross-reaction, which also indicates that the baby can have the same reaction to products that are similar. For e.g., the baby who has an allergy to cow milk could even show allergic reactions to that of goat milk or buffalo milk, etc.

3. Blood Test

This test will help in the estimation of the antibodies in the body as they are the ones that trigger the allergic reaction. The doctor can even prescribe a stool test to further confirm the allergy and rule out the possibility of other infections and conditions.

4. Skin Prick Test

This test is done by placing a few droplets of formula milk on the back of the baby’s arm. After this, the skin is pricked so that the milk enters the skin. After waiting for fifteen to twenty minutes, the skin is checked for any itchy rashes or red bumps, etc.

This test is done on young babies who are less than six months old. The diagnosis of the doctor is the deciding factor if the original formula needs a replacement.
