How To Tell If A Newborn Is Lactose Intolerant

My Doctor Says Tests Confirm My Baby Has Lactose Intolerance

Does your Baby Have Lactose Intolerance Or Cows Milk Allergy?

Some doctors might diagnose lactose intolerance if they measure excess acid in a babys poop or hydrogen gas in a babys breath due to temporary lactose intolerance . Noble and Bovey state that the presence of reducing sugars in a babys poop can be quite normal for breastfed babies particularly under six weeks of age11 while the Australian Breastfeeding Association says both a hydrogen breath test and a test for reducing sugars in the stool are often positive in normal breastfed babies under three months of age12. James Akre explains:

Excerpt from

James Akre, Infant Feeding the Physiological Basis, WHO, 1992

It is usual to find reducing substances such as sugars in the stools of healthy breast-fed infants they contribute to maintaining the acid environment that retards the growth of pathogens. In contrast, the delayed gut transit time of industrially prepared milks permits almost total metabolism of these sugars.

Prematurity And Lactase Deficiency

Though lactose intolerance is not common in babies, some babies who are born before 34 weeks donât have a fully functional gastrointestinal tract. They may lack lactase and other enzymes they need to digest food, though these can develop later as the child grows. Interestingly, these premature infants may still tolerate intact milk protein based formulas.

Quick Onset Of Symptoms

All of these symptoms are common enough to indicate any number of illnesses but a key differentiator between other illnesses and food intolerances is the quick onset of symptoms. Any of these signs will appear within 30 minutes to 2 hours of consuming milk or dairy-based products if your child is lactose intolerant.

My Doctor Said I Should Stop Breastfeeding

Some doctors are confused about temporary lactose intolerance, milk allergy and colic. They may recommend lactose-free formula or newer special formulas. However the answer to most cases of temporary lactose intolerance is to get help with breastfeeding rather than switch to industrial formulas. A baby with an irritated intestine needs the anti inflammatory effects of breast milk and a breastfeeding specialist can help suggest changes to feeding management10.

Inappropriate Use Of Lactose

Single Working Mom: Lactose Intolerant Symptoms In Babies

A recent survey in Northern Ireland assessed formula prescription patterns in infants with likely non-IgE-mediated CMA. The survey found that thickened anti-regurgitation formula, lactose-reduced partially hydrolyzed formula or lactose-free, cows milk protein-containing formulas were commonly prescribed in infants with symptoms suggestive of non-IgE-mediated CMA . The survey was repeated after the implementation of active education and national feeding guidelines . Following the educational interventions, the use of EHF and AAF increased by 63%, while the use of alternative treatments was reduced by 44.6%. Overall, the recognition of CMA increased from 3.4% to 9.8% of treated infants. This study demonstrates both the need for health care provider education on gastrointestinal CMA, as well as the usefulness of educational campaigns and national treatment guidelines.

General: Excess Fussiness Sleeplessness Or Colic

How can I know if my 8 month old has a dairy intolerance?

Every baby cries, but crying continuously and inconsolably for extended periods is unusual. You might hear someone say a baby who cries a lot has colic. Some doctors find colic controversial, but excess crying comes from somewhere, often with insomnia. Doctors also often downplay fussiness, which can delay diagnosing CMA. We hear this from parents all too often!

When should you suspect that crying is excessive and something serious is happening? The going adage is to talk to the doctor if it happens in threes. That is: if your baby cries for 3+ hours in a day, for 3+ days in a week, for over 3 weeks. That can signal gastrointestinal pain, which could result from CMA.

Extreme fussiness can also come with reflux, a rash, or other factors. Keep this in mind when asking your childs doctor about the possibility of CMA.

Why Is Lactose Important

Lactose is important to a babys health. It aids in the absorption of calcium and phosphorus and supports the growth of good bacteria in the intestinal tract. Good bacteria are major players in the prevention of disease. They inhibit the growth of harmful microorganisms bacteria, viruses, and parasites – that live in the intestinal tract and those entering the body in food and fluids. Good bacteria help to keep the walls of the intestines healthy, preventing harmful microorganisms from entering into the blood stream. Good bacteria also aid in the digestion of lactose.

Galactose, a simple sugar that comes from the breakdown of lactose, is vital to a healthy brain and nerve tissues. Galactose can be found is some foods, but milk containing lactose will be a babys only source of galactose during the early months – an important time of rapid brain growth and development.

Glucose, the other simple sugar that bonds with galactose to form lactose in milk. Glucose is essential for energy, growth and cell development. Without glucose in the diet a baby will use body fat as a source of energy, and lose weight. A baby will not survive if deprived of glucose for a long period. Most foods, including lactose-free milk, will be broken down or converted into glucose in the body.

Does Lactose Intolerance In Infants Cause Colic

Think about it: If it did, there would be no “witching hour.” Lactose consumption is pretty steady throughout the day, but colicky fussing tends to peak in the evening. But let me explain how this theory got started, and why it’s a myth.

The lactose your baby eats is digested by the enzyme lactase in the intestine. With age, adults have less and less lactase. This makes some of us lactose intolerant causing bloating, bellyache and diarrhea after eating dairy products. This adult problem led some doctors to speculate that colicky babies might be suffering from stomach pain from lactose intolerance.

Soon, the markets were flooded with lactose-free formulas and special lactase-containing colic dropsall claiming to be a cure for colic and lactose sensitivity in babies. But this multimillion-dollar promotion was based on hype not health. A Canadian study showed no improvement from lactose-free formula in colicky babies. And an Australian study found no reduction in crying when fussy infants were given lactase in their mothers milk.

Treatment Of Infants With Congenital Lactose Deficiency

In infants with congenital lactase deficiency, breast milk or lactose-containing formula cause persistent watery diarrhea and growth failure. In this situation, breast feeding can generally not be sustained. Infants with congenital lactase deficiency require a change to a lactose-free formula. If recognized and treated early, infants with congenital lactase deficiency achieve normal growth and development . Lactose restriction needs to be continued for life. However, older children and adults may tolerate small amounts of dietary lactose, depending on the disease severity.

If babies have more severe or persistent issues, it could signal an underlying cause like a cows milk protein allergy.

Symptoms Blamed For Lactose Intolerance

Lactose intolerance is often blamed as being a contributory factor for colic, resulting in cessation of breastfeeding and substitution of lactose free formula. Infants with gastrointestinal symptoms on exposure to cows milk are more likely to have cows milk allergy than lactose intolerance

Green and frothy bowel motions may be a sign that the baby is receiving too much lactose, which has a rapid gut transit time. This may be due to an excess of the early less fat-rich milk or switching the baby between breasts before emptying one breast first. Babies may be very unsettled and windy. Mothers may have an overactive letdown reflex.

Assessment by an experienced breastfeeding worker may be beneficial to ensure optimal milk removal by the baby is taking place before considering lactose free formulae. Imbalance of milk transfer can produce similar symptoms i.e. loose bowel motions, which may be green and frothy. This is due to the rapid transit time of large volumes of lower fat milk and consequently an excessive consumption of lactose . Breast compression when the baby is not actively sucking may improve milk transfer.

Babies can exhibit excess wind and gastric discomfort, which may be diagnosed as lactose intolerance, but which in fact is transitory lactase deficiency i.e. too much lactose for the available lactase.
