Hello doctor. About a year ago, my digestive system showed signs of disorder. I have the following symptoms: flatulence after eating, eat little but quickly fill up, many meals look at the tray of rice, I already feel full.

Dear Doctor, I am 50 years old. 25 years ago, I had bloody stools, then after half a month of treatment, there was no more bleeding, but since then, I have had abdominal pain, bloating, erratic bowel movements.

I am 24 years old. Before, I had stomach disease but it has not hurt for more than a year now. Suddenly these days, every day after a meal, I have abdominal pain (liquid). Even one day, when I just put down my chopsticks, my stomach hurts, sometimes it hurts, sometimes it hurts. So the doctor asked me, what is the disease after eating with loose stools? I thank you doctor.

I have had a colonoscopy since June 2021 and discovered that I have superficial ulcerative cecum. So the doctor asked me if superficial cecal ulcer is dangerous? How soon should I have another endoscopy? Thank you doctor.

Sometimes when I go heavy, I see that the stool has things I have eaten but can't digest like corn kernels, or when I eat vegetables, I see green pieces when I go heavy. So the doctor asked me to go out and eat undigested food, what is the disease? Thank you.
