Have you ever had diarrhea or bloated stomach without digesting milk? As quite a few people experience these symptoms, they often call them milk allergies and are reluctant to eat milk and other dairy products. Today, we’re going to learn more about lactose intolerance, which is known to be caused by lactase deficiency. If you usually drink milk and feel bloated or have diarrhea, please refer to it.
What is lactose intolerance?
The exact medical name for lactose intolerance is lactase deficiency, which is caused by a lack of enzymes that break down lactose, as can be seen in the word. Here, lactose is decomposed and absorbed in the form of galactose and glucose by a digestive enzyme called lactase, and in humans, it is born with the ability to secrete lactase and is an important criterion for determining milk intake depending on the production of this ingredient. But in a person who lacks lactase, lactose in milk is not broken down and absorbed, but it passes through the digestive system, which is fermented by microbes in the intestine, causing gas to cool down, which is called lactose intolerance.
The cause of lactose intolerance
There are three main causes of the disease. The broad primary characteristic is that the incidence rate varies slightly depending on race, and it is known that it is closely related to the degree of dairy intake such as milk, cheese, and yogurt, and an individual’s ability to digest lactose, and Asians may lack the aforementioned lactase from childhood.
Lactase is secreted from small intestine cells, and when damaged by disability infections such as rotavirus, inflammation occurs, and lactase cells may disappear together and may not regenerate again in the process of naturally healing the inflammation. If you drink dairy products while the ingredients are gone, the disease will appear because it is not digested as well as before. In this case, there are cases where simple milk allergies are thought of and dairy products are avoided.
The rarest of the three types is due to autosomal recessive inheritance, which results in a congenital lack of ability to break down lactose. Therefore, in this case, when a newborn baby eats powdered milk or breast milk, it sometimes causes diarrhea.
Various symptoms
People with lactose intolerance always show abnormal symptoms not only by eating milk but also cheese and yogurt. At first, you feel uncomfortable in your stomach, but in most cases, you get bloated or cause abdominal pain, and eventually have diarrhea. For reference, the amount of lactose that causes the milk allergy varies slightly from person to person, depending on the amount of lactose intake, the degree of deficiency of lactic acid, and the type of food containing lactose. Therefore, even if you eat a small amount, you may get an immediate reaction.
How to find out if you have lactose intolerance
The lactase deficiency can be determined by comprehensively judging symptoms, medical history, and promotion, but most of them can measure the amount of hydrogen in breathing, starting with lactose resistance tests, and determine whether it is a variability test. Therefore, it is better to clearly understand your physical condition through these tests rather than seeing milk allergies after drinking dairy products.
In the case of patients with the disease, it is recommended not to eat dairy products including milk, but if you need to drink it, it is recommended to eat lactofree products that remove milk sugar from the market.
