The immaturity of the digestive system in infants and the associated symptoms are a common cause of concern for parents. When does a baby's digestive system mature? On the forum, many worried parents ask when the immaturity of the digestive system in infants will end and how to survive this difficult time?
In today's article, we have collected the most important information about the maturation of the digestive system in infants.
How is maturation of the digestive system in infants?
The process of maturation of the digestive system in infants begins already in fetal life. It then progresses dynamically throughout the first years of life. The speed of this process is determined by various factors, including:
- how to feed the baby;
- possible prematurity;
- infections;
- medications used.
Exclusive breastfeeding in the first 6 months of life is the most recommended method of feeding by WHO, supporting the maturation of the infant's digestive system.
Maturation of the digestive system in infants includes:
- changes in the secretion of digestive enzymes: mouth, stomach, pancreas and intestines;
- development of the immune system: over 70% of human lymphocytes are cells of the lymphatic tissue associated with the digestive tract;
- differentiation of intestinal microbiota: mainly under the influence of the food consumed;
- sealing the intestinal mucosa barrier;
- gradual improvement of the motor function of the gastrointestinal tract.
