28th health concern - staying up all night going back and forthㅠㅠ indigestion as well.

Lately, I haven't been able to digest food well. The amount and timing of my meals are similar to before. I used to be able to eat a lot at once and still digest it easily. I couldn't understand why others complain about feeling bloated and having stomach pain due to indigestion. Now that I am older and my digestive function isn't as good as before, I often feel bloated and uncomfortable when I can't digest food properly. Also, I have never had diarrhea before, but this year I have experienced it three times. My stomach rumbles all night, and I keep going back and forth to the bathroom, which drives me crazy. The next day, I feel nauseous and exhausted, making it impossible to go to work. I always keep antacids and anti-diarrheal medication on hand just in case I get sick again. I wonder if I feel better after eating? I get anxious checking myself. When I feel something is off, I always have indigestion. I'm worried that something serious might be happening. I'm afraid to go to the hospital. ㅠㅠ
