Some people have diarrhea when they drink milk, but what is going on?

With people's higher and higher requirements for the quality of life, eating breakfast is also more nutritious, milk has gradually appeared on our table, milk has high nutritional value, simple and convenient, so it has become the first choice of many office workers, but some people will have diarrhea as long as they drink milk, what is going on?

In fact, the main reason for diarrhea when drinking milk is lactose intolerance, as long as you drink milk, you will have diarrhea. To put it bluntly, it means that lactose cannot be digested. But milk should be a very common food in our lives, why can't we digest the lactose in milk?

After we drink milk, the lactase enzyme in the small intestine breaks down lactose into small molecules that we can absorb. However, some people do not secrete enough lactase to digest lactose completely. So where does the indigestible lactose go?

Indigestible lactose will eventually be broken down by bacteria in the large intestine, which can then lead to bloating, stomach pain and even diarrhea. So is lactose intolerance innate? This is not necessarily, lactose intolerance is roughly divided into three categories: one is born, which is relatively rare; There is also a decrease in lactase secretion due to changes in the small intestine, such as surgery.

This condition can be slowly recovered. The third is that you can drink milk when you are young, but when you grow up, you will gradually become lactose intolerant, and lactose intolerance will change with age.

In fact, it is not only age, but also the difference in lactose intolerance between different races. For example, we yellow Asians have a much higher percentage of lactose intolerance than Europeans. So what if you can't drink delicious milk when you grow up?

If you have lactose intolerance, there are actually quite a few solutions. For example, if you can't drink regular milk, but you can drink yogurt, this is because yogurt will break down some lactose when it is fermented. After we drink it, it will alleviate the problem of lactose intolerance to a certain extent.

If you don't like yogurt, you can drink less milk each time, or eat some food while drinking milk. If this is still uncomfortable, you can also drink lactose-free milk.

Some people's physique produces antibodies to milk, it depends on the individual's physique, everyone's body functions are different, some people eat a certain food allergy, some people are allergic to flowers.

Some people will have diarrhea when they drink milk because they are lactose intolerant, resulting in lactose not being completely broken down and making it easy to have diarrhea.

It is because some people are lactose intolerant, and the intake of lactose can cause the body's sensitivity, and it may also be the gastrointestinal discomfort caused by the milk after it is cooled.

What are the causes of diarrhea when drinking milk

OneLactose intolerance

Lactose intolerance refers to the digestion of lactoseLactase deficiency,This causes a series of symptomatic manifestations. In milk, there are a lot of themLactose, the lactose content is:。After this ingredient enters the human intestine, it can promote the intestinal tract toZinc, iron, calciumand other mineral elementsFast-absorbing

This lactose is also able to promote intestinal tractsBifidobacteriaThe mass multiplication can improve the microecological balance of the human body, and can also promote the synthesis of large amounts of intestinal bacteriaB vitaminsIt has a very strong protective effect on intestinal health.

However, there are a lot of people in the human bodyLactase activity is low, or in vivoLactase is substantially reduced。As a result, some of the lactose that enters the intestine becomes malabsorbed. After undigested lactose enters the intestines, it is affected by bacteriaFermentationand generate a series ofGas, thus allowing the patient to appearBloatingsituation.

Moreover, lactose that has not been completely digested and the products that have been fermented by bacteria will make the intestinalOsmolality rises rapidly。As a result, the amount of water flowing into the intestines increases substantially, causing the patient to experience recurrent diarrhea.

IIAllergy to cow's milk

Some people do not have very low lactase activity and do not experience lactase deficiency or decrease. However, it can produce some components in milkAllergiesphenomenon, for example, in milkProteins。It is produced when the protein in milk enters the bodyImmunoglobulinsIt causes the human body to have a reaction.

As a result, systemic allergies can occur.

If the allergy symptoms are mild, the patient will only experience mild allergiesBloated abdomenPhenomenon. In addition, when drinking milk, the patientCorners of the mouthwithlipsLocations will also appearSlight redness and swellingsituation.

IIIDecreased gastrointestinal function

If you have a range of gastrointestinal disorders, such as:Chronic gastritisOr yesStomach ulcerstime, gastrointestinalDigestive functionwill be lowered quickly.
