My lactose intolerance comes and goes. Why is this happening?

It is said that 7 out of 10 Koreans have lactose intolerance.

I also naturally drank a lot of soy milk because of my lactose intolerance.

But I like milk too.

There is also lactose-free milk that is easy to digest, but

The price range was a bit more expensive than regular milk.

So I used to just drink regular milk.

I found that it's fine if you keep drinking regular milk consistently.

But does this also depend on age?

They say I used to always have a stomachache.

These days, the proportion of people who are okay has increased compared to those who are sick.

Before, I had a really hard time even after drinking that banana-flavored milk.

These days, I mix black sesame powder into milk and drink it, and it doesn't bother me at all.

^^;;; But then again, it's not like it doesn't hurt at all, and the pain rate is definitely

It's less than before.

Maybe it's the effect of age... but as I get older, I'm experiencing many things changing... It's making me a little sad... T_T
