Lactose intolerance means that some people lack lactose due to the intestinal tract and cannot digest the lactose in the milk. This causes gastrointestinal symptoms such as bloating, abdominal pain ,nausea and abdominal pain cramping after eating milk and dairy products.
Among the populations with lactose intolerance, the black and yellow populations are the most frequently seen because the two populations rarely touch dairy foods during infancy.We can do a test for lactose intolerance before drinking milk
In China, more than 10% of infants and young children in lactation will have congenital lactase deficiency symptoms, and this proportion will become higher and higher with age.
The study shows that the incidence rate of children aged 3-5 years is 38.5%, the incidence rate of children aged 7-8 years is 87.6%, and the incidence rate of children aged 11-13 years is 87.8%, while the rate of lactose malabsorption in healthy adults is as high as 92%.
The main manifestations of lactose intolerance are some gastrointestinal symptoms , such as abdominal tension, bowel, abdominal pain, exhaust, and diarrhea. If these symptoms are one of the manifestations of lactose intolerance, the symptoms of individuals with lactose intolerance vary widely, while severe lactose intolerance occurs more than 30 minutes to several hours after ingesting a certain amount of lactose...
Lactose intolerance has a great impact on infants and young children and is accompanied by diaper rash, vomiting, growth retardation, etc. Adults sometimes have nausea reactions. The number and severity of intolerance symptoms are related to a variety of factors, such as lactase activity in the small intestine, the amount of lactose ingested, and whether other foods are ingested at the same time.
Lactose intolerance affects various minerals in milk, such as calcium, iron, phosphorus absorption, resulting in calcium deficiency, zinc deficiency, and iron deficiency and pelvic blood symptoms; lactose intolerance can also cause vitamins, protein and other infants in milk The essential materials for growth and development of young children are difficult to be digested and absorbed by children, causing problems such as low body weight and slow growth and development.
Because lactose is intolerant, when drinking milk, milk can not be completely decomposed, digested and absorbed in infants and young children, and stays in the intestinal cavity. Under the action of bacteria, various harmful substances are formed, causing intestinal flora imbalance and causing gastrointestinal disease symptoms. Long-term lactose intolerance can lead to diarrhea in babies with chronic diarrhea and diarrhea that are difficult to cure in children.
If your baby is lactose intolerant, you may experience diarrhea, abdominal cramps, bloating or farting between 30 minutes and two hours after drinking breast milk or eating other dairy products (such as cheese or yogurt that you start after eating complementary foods). It should be noted that the baby should not drink fresh milk until the age of one.
Lactose intolerance occurs less frequently in infants and is more common in adults. According to reports, the proportion of Chinese with lactose intolerance is as high as 93%. Most people have symptoms of intolerance only when a certain amount of lactose is ingested, and only a very small number of people take a small amount of lactose to have a serious condition. Infants usually synthesize lactose normally, so they can digest and absorb lactose in breast milk. After weaning, the synthesis of lactose in the body will gradually decrease. Lack of lactose intolerance can result in lactose intolerance in the small intestine due to various reasons.
Although lactose intolerance has a great impact on the human body, there are many effective ways to deal with it, and the right product should be chosen.
