This year, I am 20 years old. I feel that my digestion is not good, sometimes I have a boil in my intestines, I easily have loose or raw stools, I feel a bit tired but I do not have vomiting or fever. Symptoms occur every day or every other week, difficult to predict. I also only use probiotics but not completely. I always eat 3 meals on time, clean, do not use any harmful stimulants. So the doctor asked me sometimes what is the disease when boiling in the intestines with loose stools? What should I do doctor? I thank you.
