Lactose Intolerance Test At Home For Baby

How do you test a baby for lactose intolerance?

Infant lactose intolerance is due to less lactase secretion, also known as lactase deficiency. Lactase deficiency is a widespread worldwide problem. The incidence of the Far East population is high, and most people do not have symptoms. However, diarrhea and other symptoms often occur in neonates and infants with milk as the main diet.

The peak ages of lactose intolerance in different countries are different. Japan is 7-8 years old, Africa is 3~5 years old, and 1168 healthy children aged 3-13 years in Beijing, Shanghai, Guangzhou, and Harbin have investigated lactase. The incidence of deficiency is high, and 87% of children with lactose intolerance occur between 7 and 8 years of age.

The main symptom of diarrhea several times a day to more than 10 times, most of the children have more intestinal gas, often bring a small number of feces on the diaper. Most of the stools are yellow or blue-green, or egg-flower soup, foamy, with milk, and a few children have milk or vomiting. Because the effect of lactase is low, the child will be accompanied by bloating and varying degrees of uneasiness, easy to cry, defecation or improved diarrhea after treatment. Intestinal colic is rare and often occurs in the course of the disease, but it can also occur before diarrhea in babies. In severe cases, dehydration, acidosis, growth retardation, etc. can occur, and there is no fever.

Pediatric diarrhea is a group of digestive tract syndromes characterized by multiple causes and multiple factors, which are characterized by increased frequency of stools and shape changes. It is a common disease in infants and young children in China. The high incidence period within 1-year-old is the main cause of malnutrition, anemia, and growth and development disorders in children.

In daily care, many babies will have diarrhea and children's diarrhea and vomiting . There is a saying that lactose intolerance can cause diarrhea in the baby. But is this the case? Today, let us uncover the true causal relationship between “lactose intolerance” and “diarrhea”.

First of all, there are many reasons for baby diarrhea. For example, sudden changes in climate, disorders of the baby's gastrointestinal system function, and infection with viral bacteria may be the cause of diarrhea. Diarrhea is prone to damage the baby's small intestine epithelial microvilli, resulting in a lack of secondary lactase. Lactose deficiency causes lactose to enter the large intestine and produce a large amount of gas, which causes the baby's intestinal tract and flatulence.

At the same time, the unabsorbed sugar and fermentation products form a highly permeable environment, forming osmotic diarrhea, which causes the symptoms of diarrhea to increase. If the symptoms of diarrhea in the baby are aggravated, it will continue to aggravate intestinal mucosal damage and aggravate lactase deficiency.

Look at the so-called lactose, which is a kind of sugar contained in dairy products. It must be hydrolyzed by lactase to become two monosaccharides in the small intestine, namely glucose and galactose. Lactose-deficient people, after eating milk or dairy products, lactose in milk can not be completely digested and absorbed in the intestinal lumen, so that the osmotic pressure of the intestinal contents is increased, the intestinal emptying is accelerated, so that lactose is quickly discharged. The large intestine is fermented by the action of bacteria. Mild symptoms are not obvious, and heavier people may have symptoms such as abdominal distension in newborn, bowel, exhaust, abdominal pain, and diarrhea. Doctors call it lactose intolerance.

It can be seen that after diarrhea occurs, the small intestinal epithelium is damaged and the lactase is greatly reduced, resulting in the lack of secondary lactase, which leads to lactose intolerance. However,infant  lactose intolerance caused by diarrhea will further aggravate the symptoms of diarrhea.

Therefore, when your baby has a condition that is difficult to improve with diarrhea, parents should pay attention to whether the baby is lactose intolerant.

When your baby has diarrhea, start removing lactose from the food, such as ordinary milk powder for your baby, to prevent the increase in lactose intolerance and prolong the course of your baby's diarrhea. At this time, the most simple and effective way is to replace the diarrhea milk powder with the lactose-free formula for targeted conditioning, and after the diarrhea is improved, adhere to the diarrhea milk powder for 2-3 weeks to consolidate the effect.

In the choice of diarrhea milk powder, pay special attention to the lactose content in the formula table. The national standard regulates the so-called lactose-free formula, that is, only lactose content below 0.5 g / 100 g of milk powder can claim "lactose-free formula."

  Pay attention to the difference between the lactose-free formula and low-lactose formula when choosing diarrhea milk powder. There are also some claims that the so-called "lowering lactose", in fact, the lactose content far exceeds the standard of 0.5 g / 100 g of milk powder, so should pay attention to choose to indicate "lactose-free formula" when buying milk powder.
