Symptoms of lactose intolerance

summary

Lactose intolerance mostly occurs in newborns and infants, whose main food is milk. The reason is that infants secrete less lactase, which leads to the inability to completely digest and decompose lactose in breast milk or milk powder, thus causing diarrhea. This is not caused by bacterial or viral infection, so it is also called lactase deficiency. The incidence of lactose intolerance is quite high in China. The main carbohydrate in breast milk or milk powder is lactose. If the lactase secretion is insufficient, part of lactose will be decomposed into lactic acid and carbon dioxide by the colonic flora. Lactic acid will stimulate the intestinal wall, resulting in accelerated intestinal peristalsis and diarrhea. Let's talk about the symptoms of lactose intolerance.

Symptoms of lactose intolerance

Lactose intolerance is generally divided into congenital lactase deficiency, secondary lactase deficiency and adult type lactase deficiency. Newborns are generally congenital and related to race and heredity. And the secondary often occurs after enteritis, which leads to the damage of the top of intestinal villi, and then leads to the lack of enzymes. Adult type is the most common, closely related to eating habits, mainly because with the growth of age, the activity of lactase gradually decreased, or even disappeared, resulting in lactose intolerance or malabsorption.

If the child breast-feeding, formula or milk products, diarrhea, stool thin with foam, odor, abdominal distention, abdominal pain, spastic abdominal pain, fart, vomiting, and so on, these symptoms are most likely to be lactose intolerance, parents should cause a note, timely to the hospital.

In general, lactose intolerance does not need drug treatment. As long as we adjust the diet structure, avoid lactose containing food or lactose free dairy products, pay attention to supplement probiotics, we can choose probiotics suitable for children, which can improve the intestinal metabolic environment and enhance resistance. In addition, it can also supplement lactase and so on.

matters needing attention
