Lactose Intolerance Test At Home For Baby

Lactose intolerance vs milk allergy

Lactose intolerance stemming from the digestive system

Lactose is a disaccharide widely found in mammalian milk. About 4.5 grams of lactose is contained per 100 milliliters of milk. Lactose can be absorbed after it is broken down into glucose and galactose by lactose in the human small intestine.

Babies can normally synthesize lactase and thus digest and absorb lactose from breast milk. After weaning, the synthesis of lactase in vivo will gradually decrease. If this lactase is absent in the small intestine for various reasons, a large amount of undigested lactose can reach the large intestine smoothly. Some bacteria in the large intestine ferment with lactose to produce a large amount of gas, which can lead to symptoms of diarrhea   ,abdominal distension, diarrhea, and farting . This is lactose intolerance.

Lactose intolerance varies greatly among different races. White people in Europe and the United States usually have less lactose intolerance because they  test for lactose intolerance,while the proportion of Chinese people with lactose intolerance is as high as 93%. Moreover, individual differences between people with the same lactose intolerance are also significant. Most people suffer from intolerance only when they take in a certain amount of lactose. As a result, people with lactose intolerance can still eat a small amount of milk. Only a very small minority of people are in the same situation as Lenard in TBBT, where a small amount of lactose can lead to serious problems.

Milk allergy from the immune system

Milk allergy, more specifically, is allergic to protein in milk. Every 100 milliliters of milk contains about 3 grams of protein, including casein and whey protein. Both proteins can cause allergies. When the immune system mistakes the normal intake of milk protein as an invading enemy, it triggers a series of immune responses to fight the "enemy". The result may be vomiting, diarrhea, skin swelling, asthma and other symptoms. When the immune response is too strong, untimely rescue may even lead to death.

Infants are more susceptible to milk protein than adults because their immune system is not yet mature. About 3% of babies are allergy to milk protein. Moreover, infants who are allergic to milk proteins are usually allergic to proteins from other animal milk, and even to proteins from breast milk. In addition to milk protein, proteins in eggs and peanuts are often allergens for infants. In most cases, the allergy will disappear after a few years. Of course, there are a few people who have been allergic to certain proteins even in adulthood, such as Howard, who is severely allergic to peanuts in TBBT.

Although locatose intolerance in infants is rare.there are still some infants with congenital lactase deficiency, in which case they need to be hydrolyzed to glucose and half under the guidance of a doctor. Lactose-free formula infant formula.

If you are lactose intolerance in adults, you can relieve the symptoms by drinking milk in small portions and multiple doses. Since the main nutrients of milk are digested and absorbed mainly in the stomach and small intestine, even if there is slight lactose intolerance, it will hardly affect the digestion and absorption of nutrients.

Whether it is lactose intolerance or milk allergy, you need to find the root cause, the right medicine, choose the right product according to your situation.
