Lactose Intolerance Test At Home For Baby

After milk you diarrhea ,lactose intolerance ?

Posted on December 21, 2019 by Rebecca

Maybe many people have this experience. They used to drink milk and they didn't have anything. They didn't know when to start drinking milk and diarrhea. I thought it was allergic to milk, but drinking yogurt was fine or drinking a small glass of milk after a meal was fine. This phenomenon is most obvious to Asians. This is lactose intolerance caused by lactase deficiency.When I drink milk and have diarrhea, it may be gastrointestinal discomfort or lactose intolerance

 Infant lactose intolerance, a simple explanation is that the intestinal tract affects lactose digestive disorders and causes intestinal symptoms such as flatulence, intestinal cramps or diarrhea. The main cause is the lack of lactase.

For most mammals, including humans, lactase maintains high activity until the age of 2, and most people's lactase activity lasts until 2-15 years, then gradually decreases to adult levels, about normal. 10% of infant enzyme activity levels. However, it is currently only found in some humans that lactase can remain active until adulthood or even life.

Due to different dietary environments and habits, lactose intolerance also has genetic differences determined by genetics. The incidence of Caucasians, especially in Northern Europe, is significantly lower, such as 2%-15% in Northern Europe and 9%-23% in Central Europe. In the United States, 6%-22% of Caucasians and 20%-30% of northern India, and the prevalence in Asia can reach 95% to 100%. (Figure 1. Lactose intolerance profile)

How is lactose intolerance formed?

In the human intestines, countless enzymes help break down food,what mean of the enzymes definition.Among them, lactase is the most mature in the small intestinal mucosa disaccharidase, the lowest content, the most vulnerable, the slowest recovery, and closely related to human health. Lactose is hydrolyzed by lactase into galactose and glucose and absorbed by the body.

When the intestinal mucosal lactase deficiency or enzyme activity is reduced, lactose can not be decomposed, stay in the intestine, and be decomposed by the intestinal bacteria into lactic acid and CO2 gas, causing symptoms such as flatulence, intestinal cramps, and diarrhea. (Fig. 2. Intestinal lactose decomposition diagram) Infant lactose intolerance

 Sometimes, premature babies will not produce enough lactase for some time, because the baby's lactase levels generally increase in the final stages of the third trimester. The phenomenon of congenital lactose intolerance in babies is very rare. A baby with congenital lactose intolerance can only drink special, lactose free infant formula.

Most babies are caused by diarrhea caused by lactose intolerance, especially rotavirus enteritis. Rotavirus not only destroys the intestinal mucosa but also reduces the secretion of lactase. It also directly acts on lactase to destroy it, causing secondary lactose intolerance, which makes diarrhea difficult.

Especially for babies who are mother or infant or milk powder, a vicious circle will be formed: diarrhea, lactase is destroyed, and lactose intolerance increases diarrhea. Therefore, when the baby has severe diarrhea, it is necessary not only to supplement the probiotics but also to properly supplement the lactose and reduce the lactose intake.

Lactose intolerance main symptoms and effects

The common symptom of infants and young children is diarrhea, and the typical stool is a yellow loose stool. With foam and acid odor, and abdominal discomfort, abdominal distension and other symptoms. The symptoms of diarrhea disappeared several days after the lactose diet.

Lactose that has not been hydrolyzed by bacteria is decomposed by bacteria to produce gas, which causes abdominal symptoms. Its toxic metabolites (such as formic acid, acetaldehyde, ethanol, hydrazine, short-chain fatty acids, peptide toxoids, etc.) change the mechanism of signal transmission between cells. It causes the patient to have systemic symptoms such as headache, inattention, memory loss, mouth ulcers, arrhythmia, muscle and joint pain, frequent urination, various allergic reactions (eczema, asthma, itching, etc.). Lactase deficiency also affects the absorption of calcium by small intestine tissue, which causes calcium deficiency or rickets in children.

lactose intolerance and lactose tolerance

You may think that lactose intolerance is similar to milk allergy. Milk allergy is a reaction of the body's immune system, and lactose intolerance is a problem of the digestive system. However, the symptoms of the two are very similar. For example, milk allergy or lactose intolerance may cause abdominal pain or diarrhea after eating dairy products. Every time your baby eats dairy products, it will appear dry and itchy rash or swelling of the face, lips, mouth, or urticaria, tears, runny nose, etc., then the baby may be allergic to milk protein.

Lactose intolerance treatment

Unfortunately, lactose intolerance is neither treatable nor preventable. However, if the baby is lactose intolerant, we can take the following measures to help alleviate the baby's discomfort:

(1) Reduce or avoid the consumption of dairy products, or switch to lactose-free/low-lactose milk powder.

It is based on cereals, soy milk or legumes, and meat-free foods such as meat. For infants under the age of 2 who use milk as their staple food, they can switch to lactose-free milk powder.

Lactose-free milk powder replaces lactose with carbohydrates such as maltodextrin or corn starch, while the ingredients of formula, such as protein, fat, vitamins and trace elements, are still preserved. Generally, supermarkets can also buy them. Supermarkets or infants are lactose-free/low-lactose. Diarrhea milk powder.

(2) Eat with cereals

In general, children who drink milk on an empty stomach will have more severe symptoms, but the lactose concentration of milk may be “diluted” in a given environment when fed on a mixed diet. Therefore, children can eat some biscuits before drinking milk or drinking milk, which will reduce the feeling of intestinal exhaust and relieve discomfort. If your babies drink milk powder for babies, it is also a good idea to try to add some cereals to eat.

(3) replace milk with yogurt

Yogurt is produced by fermentation after adding certain Lactic acid bacteria. The fermentation process breaks down 20%-30% of the lactose in the raw milk into lactic acid. The protein and fat are decomposed into small components. The minerals beneficial to the human body such as calcium, iron, and zinc are also decomposed. Therefore, for lactose intolerant babies, yogurt that is easier to digest is a good choice.

(4) Lactase

Directly supplementing lactase is the easiest and quickest way. Taking lactase capsules before each meal or before drinking milk can alleviate the symptoms.
