Side effects of lactose-free formula are usually mild, like gas or fussiness, but can sometimes mimic a cow's milk protein allergy (CMPA) with rashes, vomiting, or breathing issues, requiring medical attention; it's crucial to distinguish lactose intolerance from a protein allergy, as lactose-free milk doesn't help CMPA, and some evidence suggests potential metabolic differences or sweeter taste affecting long-term habits, so consult a doctor before switching formulas, especially if severe symptoms appear.
There may be further risks associated with using a lactose free milk as diets without lactose may have disadvantages for the composition of the infants' colonic microflora and colonic physiological function, and may compromise calcium absorption.
If your baby is distressed, remove lactose for 2 days [use a lactose free formula/milk and follow a lactose free diet]. If the symptoms improve then continue with the lactose free formula/milk and diet for up to 8 weeks to allow resolution of symptoms.
Lactose-free formula
This formula is suitable for babies who are lactose intolerant. This means they cannot absorb lactose, which is a sugar that's naturally in milk and dairy products. Lactose intolerance is rare in babies. Symptoms include diarrhoea, abdominal pain, wind and bloating.
Signs to watch for include:
Symptoms of lactose overload
frequent large, runny poos which might be green, frothy or explosive*
Can lactose-free milk cause diarrhea? In actuality, lactose-free milk is still a dairy product, as was previously explained. Therefore, lactose-free milk will also cause you to feel sick and cause you to have diarrhea if you have a milk allergy.
Over 90 percent of Asian-Americans are lactose intolerant, and it is least common among Americans with a Northern European heritage.
Lactose-free milk is just as nutritious for you as regular dairy milk because it contains all the same essential milk vitamins and proteins, just without the lactose. This means all members of your family can enjoy the nutritional benefits and delicious real milk taste, even if they're lactose intolerant.
If your baby is diagnosed with lactose intolerance, a low lactose or lactose free infant formula may be recommended. If your baby is formula fed or you're considering giving them formula, consult your GP or a dietitian before using or changing to a low-lactose or lactose-free infant formula.
If your mixed feeding involves exchanging some breastfeeds for baby formula, then your baby will not receive as many benefits as they normally would if they were exclusively breastfed. As such, their immune system may not be as well protected from certain infections1.
Lactose intolerance causes symptoms like fussiness, gas, blood or mucus in stool, nausea, spit up and diarrhea. While exposure to lactose may cause your baby discomfort, it will rarely cause any long-term problems.
Common Indicators of Lactose Intolerance in Babies
Lactose-reduced formulas remove the lactose carbohydrate from cows' milk and replace it with corn syrup solids. These formulas quickly raise blood sugar and may cause rapid weight gain.
Easy to digest: With the addition of the lactase enzyme, lactose free milk is much easier to digest meaning less digestive tract discomfort such as indigestion, gas, stomach pains, bloating and diarrhoea.
Estimates for lactose intolerance vary by ethnicity. African American and Asian ethnicities see a 75% - 95% lactose intolerance rate, while northern Europeans have a lower rate at 18% - 26% lactose intolerance. For some people, drinking milk with their morning cereal is all the dairy they need for the day.
Lactose intolerance causes symptoms such as:
Abstract. Lactose intolerance occurs in about 25% of people in Europe; 50-80% of people of Hispanic origin, people from south India, black people, and Ashkenazi Jews; and almost 100% of people in Asia and American Indians.
Common Foods to Avoid if Lactose Intolerant
Lactose intolerance can lead to diarrhea, which may be watery and frequent. The body's inability to fully digest lactose can result in the unabsorbed sugar drawing excess water into the intestines, leading to loose stools.
The 7 key danger signs for newborns, often highlighted by organizations like the WHO, are not feeding well, convulsions, fast breathing, severe chest indrawing, lethargy/unconsciousness (movement only when stimulated), high or low temperature, and jaundice (yellow skin/soles) or signs of local infection like an infected umbilical stump, requiring immediate medical attention.
Some signs that your baby may need a formula change include:
Signs of overfeeding a baby include frequent spitting up/vomiting, fussiness, gassiness, a tight belly, and changes in stool (loose, green, frothy, or explosive). While babies often know when they're full (turning away, falling asleep), signs of overfeeding often involve discomfort and digestive issues, sometimes with rapid weight gain or a very full, hard tummy, especially if fed past fullness cues.
