Lack of lactase – an enzyme that breaks down milk sugar lactose – most often occurs in babies up to a year. The fact is that the pancreas, which is responsible for the production of lactase, at this age does not know how to work in full force.
The situation is similar with other “producers” of lactase: E. coli, bifidobacteria and lactobacilli. In the first year, their composition in the intestines often changes.
Then dysbacteriosis occurs, and lactase is not always produced enough.
Another cause of the problem is the “legacy” of the elders. With a congenital shortage of lac-Tazy, 6–10% of children come into the world.
If lactase deficiency has arisen in a baby due to dysbiosis and poor pancreas work, most likely, with age this problem will go away by itself. And many children forget about it help drugs that restore the pancreas and healthy intestinal microflora.
If the baby has inherited a lack of lactase from the parents, there is a high risk that this situation will continue for a lifetime. Then mother will have to exclude fresh milk from the children’s menu (the ban does not apply to fermented milk products).
And if she feeds her crumb breast – give up whole milk and the most, and at the same time limit yourself to sweets.
Can breast milk and dry mixes be given to a lactase deficient baby? To resolve this issue, you need to know how big the lactase deficiency is.
This will show the analysis of feces for carbohydrate content.
If the baby is gaining weight normally and is feeling well – feel free to feed him with breast milk or a mixture, regardless of the level of carbohydrates in the analysis.
Scarce gains the necessary kilograms, but he behaves restlessly, he has a loose and frequent stool – the baby’s “dairy” menu can be left unchanged, but before feeding you can give him lactase medication (for example, Lactase Baby).
If the weight gain is small, the baby’s milk is poorly absorbed. Then you can partially replace it with special products with a low content of lactose.
Doctors recommend low-lactose or lactose-free mixtures (such as NAN, Nutrilon, Nut-ricia) and therapeutic food with probiotics (Gallia Lactophidus, Danone) for children who do not tolerate milk. But the mixture of hydrolysates, in which milk proteins are split to make it easier to digest, the crumbs will not work.
They worsen the production of enzymes and cause dysbiosis.
