1) Congenital lactase deficiency.

⠀⠀ A rare (several cases described) disease characterized by a lack of enzyme activity from birth. It is accompanied by watery diarrhea, flatulence and, possibly, malnutrition in children. This is what we differentiate with transient enzyme deficiency in very premature infants.

2) Lactase deficiency of the adult type.

⠀⠀ The production of the enzyme is inherited according to the principle of the Mendeleev dominant trait. Over the years, in people with a certain genotype, the production of the enzyme decreases, which makes it difficult to consume dairy products and https://pillintrip.com/de/medicine/postafen-meclozine. However, not completely impossible! In these patients, at an early age, enough enzyme is produced to metabolize breast milk and / or formula. But from 12 years (the earliest recorded manifestation) may begin to decline. But, more often, after all, after 18 years.

3) Secondary lactase deficiency.

⠀⠀ This is a transient condition that occurs as a result of damage to the intestines. That is, the initial damage to the intestine (inflammatory bowel disease, infections, food allergies, etc.) causes a decrease in the production of the enzyme.

⠀⠀ In childhood, we are more likely to meet with transient enzyme deficiency in newborns. Which, as a rule, levels off by 4-5 months. In children born prematurely, the timing may be lengthened. And often we are faced with a secondary enzyme deficiency – giardiasis often causes such a simatomatics. But other bowel diseases can produce similar symptoms as well. After the correction of the underlying disease, the ability to produce the enzyme is restored.
