How Do I Know If My Newborn Is Lactose Intolerant
VERY rare: True lactose intolerance is very rare in children, especially since lactose is the primary sugar in breast milk. In 15 years I have seen 2, count 'em, 2 children who were lactose intolerant. Much more likely is cow's milk intolerance or even a mild milk protein allergy. Kids will outgrow both by around 9 to 12 mo of age. A soy formula or a "sensitive" formula help avoid the protein intolerance. ...Read moreSee 1 more doctor answer
Lactose is a type of sugar found in milk and other dairy products. Lactose intolerance develops when the small intestine does not make enough of an enzyme called lactase. The body needs this enzyme to digest lactose. This is not a milk allergy, but instead an intolerance with gastrointestinal symptoms of crampy abdominal pain, gassiness and diarrhea worse with increasing ...Read more
Not in newborn: Lactase which digests lactose or milk sugar essentially always present in newborns and levels only decrease in toddlers at age children would usually be weaned. It is lack of lactase that causes lactose intolerance. About 2-3% of infants are milk allergic so this is a more likely cause of reactions to cow milk. Switch to soy based formula and consult an allergist. ...Read moreSee 2 more doctor answers
Symptoms after dairy: Can occur as we get older, more in some ethnic groups (jews, blacks, asians), with certain parasites (giardia), after gastroenteritis. "poor man's test": drink 1 pint skim milk on empty stomach; get symptoms (gas, bloat, cramps diarrhea within 2 h). Can do lactose tolerance test (blood or breath test). Can have small amts as mixed meal; fat helps tolerance; yogurt more tolerable. ...Read moreSee 1 more doctor answer

Lactose intolerance?: Lactose breath testing (objective) or a clinical response to lactase enzyme supplements &/or milk avoidance (subjective decline in the gassiness & diarrhea associated with ingesting lactose) may clarify your concern. Some (particularly children) with suspected lactose intolerance however are intolerance to other milk components. Bleeding, weight loss, significant tenderness is not lactose intol. ...Read more
Simple test: Try avoiding all milk products for a week and then try the lactaid brand of milk/cheese/ice cream. If you don't have any problems with those then you are likely to be lactose intolerant. There is also a breath hydrogen test that some GI offices perform to more definitively diagnose the condition. ...Read more
Bloat, cramp: Bloating, cramping, diarrhea, gas, within a hour to three hours after milk or dairy products. You can have one of these symptoms or more than one. Or all of them. It may be dose dependent. The more milk and dairy you have, the worse the symptoms. There are hidden sources of milk, like certain bread crumbs. ...Read more
Eat lactose : Ifbyiunconsume lactose containing foods and become symptomatic , then you are likely to have lactose intolerance, as a result of the deficiency in the enzyme lactase. There are tests to confirm it. Avoiding or minimizing lactose intake and/ or taking lactase when eating lactose contains foods will help. See on line info on lactose intolerance, lactose- free diet and lactase. ...Read more
Found in milk. Lactose is a large sugar molecule that is made up of two smaller sugar molecules, glucose and galactose. In order for lactose to be absorbed from the intestine and into the body, it must first be split into glucose and galactose. The glucose and galactose are then absorbed by the cells lining the small intestine. The enzyme that splits lactose into glucose ...Read more
