Lactose intolerance
Lactose intolerance.
For moms and dads:
It is extremely rare to suffer from lactose intolerance from birth.
It becomes much more frequent after 5 years of age.
So, by pure statistics, lactose intolerance should not be the cause we think a priori.
For healthcare professionals:
Lactose is a disaccharide widely distributed in diet and pharmaceuticals; It is the milk sugar of mammals. Lactose is the name of the sugar found in milk. In order to transform lactose into energy, the body must divide it into smaller portions that can be absorbed. The small intestine contains an enzyme called lactase, a chemical that divides lactose. Lactose is the name of the sugar found in milk.
A loss of lactatic intestinal activity is common with age, variable between ethnic groups and genetically conditioned, which can cause malabsorption. It can also be secondary to intestinal mucosal damage and, rarely, due to congenital deficit. Malabsorption does not necessarily imply intolerance with clinical significance. Lactose excuse from the diet produces clinical improvement but, in the long term, may lead to a defect in the recommended daily intake of other nutrients such as calcium. It can be reintroduced in the diet, although the clinical tolerance threshold is individual.

A deficiency of absorption or malabsorption of lactose can be a causal factor in the appearance of colic in infants. The presence of excess lactose in the tubedigestive, not absorbed or poorly absorbed, causes the fermentation of lactobacilli and bifidobacteriaresult in an increase in lactic acid and hydrogen, with aosmotic effect, further increasing abdominal distension.
The combination of this gas and this acid can produce symptoms not only of abdominal distension, but also of pain, flatulence, nausea and diarrhea.

According to the American Society of Gastroenterology, Hepatology and Pediatric Nutrition (NASPGHAN), we highlight the following information:
Lactose intolerance can occur at any age and in children of any ethnic group. It is extremely rare to suffer from lactose intolerance from birth. In children, lactose intolerance becomes more frequent after 5 years of age.

Why can some children have lactose intolerance and others can't?
Most children produce lactase at birth and can digest lactose when they are babies. Lactose is the main sugar contained in breast milk. A child can become lactose intolerant if an infection or an allergic reaction damages the small intestine, causing a shortage of lactase production. Usually this damage is temporary, but it may be weeks or even months before the child can tolerate dairy products again. Other more chronic diseases, such as celiac disease, Crohn's disease or an infection with parasites can also cause temporary lactose intolerance. In other cases, lactose intolerance develops spontaneously over time. When children reach 3 to 6 years of age, their bodies naturally go on to produce lower amounts of lactase than those produced in the first or second year of life. In some children, production continues to shrink or even stop completely. Frequently, symptoms of lactose intolerance appear in adolescence or early adulthood. Some ethnic groups (particularly blacks, Hispanics, Asians) are more likely to develop lactose intolerance.
