Q: Is Your Baby Experiencing Diarrhea After Formula? Possible Lactose Intolerance

Hello： Breast milk also contains lactose, so your situation is likely not lactose intolerance. <br>I suggest trying a different brand of formula. <br>There is no need to specifically choose a lactose-free formula. <br>Best regards, Rensheng.

Bowel movement occurs within half an hour after consuming hydrolyzed milk formula?

My baby is currently seven months old and has been exclusively bottle-fed with breast milk.
However, due to work commitments, we have started trying formula milk.
Generally, after consuming Abbott Similac, a rash appears at the corners of the mouth within half an hour, so we switched to Abbott Gain.
Currently, the formula is given only at bedtime.
For the first one to three days, there were no issues, but in the last two days, my baby has been having bowel movements within 30 minutes to an hour after drinking the formula, about 1 to 3 times, and the stools have become increasingly watery.
When we try to switch back to breast milk, there are no such issues.
I would like to know if my child might have lactose intolerance, or if we need to change the formula brand.
Should we consider switching to a lactose-free formula?

More Info

When it comes to your seven-month-old baby experiencing diarrhea after consuming formula, it is essential to consider several factors, including potential lactose intolerance and the suitability of the formula being used.
Lactose intolerance in infants is relatively uncommon, especially in babies under one year of age. However, it can occur, particularly in those with a family history of lactose intolerance or other gastrointestinal issues. Symptoms of lactose intolerance can include diarrhea, bloating, gas, and abdominal pain, which may manifest shortly after consuming dairy products, including formula that contains lactose.

In your case, since you mentioned that your baby developed a red rash around the mouth after consuming the Abbott Similac formula, this could indicate an allergic reaction or sensitivity to an ingredient in that formula. The subsequent diarrhea, which occurs within 30 minutes to an hour after feeding, further supports the possibility of an intolerance or sensitivity to the formula. The fact that switching back to breast milk alleviates the symptoms suggests that the formula may not be suitable for your baby.

Here are some steps you can take to address this situation:
1. Consult with a Pediatrician: Before making any changes to your baby's diet, it is crucial to consult with your pediatrician. They can evaluate your baby's symptoms, perform any necessary tests, and provide personalized recommendations based on your baby's health history.

2. Consider Lactose-Free Formula: If lactose intolerance is suspected, switching to a lactose-free formula may be beneficial. These formulas are designed for babies who have difficulty digesting lactose and can help prevent gastrointestinal distress.

3. Monitor for Allergies: Keep an eye out for other signs of allergies, such as skin rashes, excessive fussiness, or respiratory issues. If you notice any of these symptoms, it may be necessary to explore hypoallergenic formulas, which are formulated to reduce the risk of allergic reactions.

4. Gradual Introduction: If you decide to try a new formula, consider introducing it gradually. Start with a small amount mixed with breast milk to see how your baby reacts before fully transitioning.

5. Hydration: Ensure your baby stays hydrated, especially if diarrhea persists. Breast milk is an excellent source of hydration, and if formula is being used, ensure it is prepared correctly.

6. Observe Bowel Movements: Keep a record of your baby's bowel movements, noting the frequency, consistency, and any accompanying symptoms. This information can be helpful for your pediatrician in diagnosing the issue.

7. Dietary Adjustments: If your baby is consuming solids, consider the types of foods being introduced. Some foods can also contribute to diarrhea, so it may be worth evaluating their diet as well.

In summary, while lactose intolerance is a possibility, it is essential to consult with a healthcare professional to determine the best course of action for your baby. They can help identify whether the formula is the issue or if there are other underlying factors contributing to the diarrhea. Making informed decisions based on professional advice will ensure your baby's health and well-being.
