(Concern) Weakness in the gastrointestinal system

I have had a weak stomach since I was a child.

As I get into my late 20s and into my 30s, my digestion gradually worsens, and it seems that aging affects my organs, making digestion even more difficult.ㅠㅠ I experience a variety of symptoms all at once, including abdominal bloating, excessive belching, stomach pain, abdominal pain, and fatigue.

So I keep avoiding eating with others, and when symptoms appear, I feel sick, weak, and even sitting becomes difficult, so I usually eat at home. Even at home, if I don't lie down immediately, the pain continues and it's hard to endure.

Please recommend effective digestive enzymes, foods beneficial for the digestive system, or special remedies.
