Question) Are there any self-treatment methods for irritable bowel syndrome?

I am suffering from irritable bowel syndrome.

The cause is unknown, but there are problems with digestive function.

It's not because I ate a specific food, but just normally eating as usual.

It is common to experience abdominal pain and diarrhea together.ㅠㅠ

Is there a way to get rid of irritable bowel syndrome?

Going to the hospital every time to get medication is exhausting ㅠㅠ

I wonder if there is no way to completely improve it.
