Your friend is 15 years old. Every time my friend ate food with a lot of animal fat, for two days after that, he had a thin white greasy scum floating to the surface of the water after having a bowel movement. My friend also did not have diarrhea, fatigue at all. So the doctor asked me what is the cause of women having a thin layer of fat when they go out?

Currently, I am facing the situation that when I eat (including both main meals and snacks), I will defecate (faeces) immediately and go many times. So the doctor asked me to go out many times after eating, what are the signs of disease? How do you treat it, doctor?

I have had symptoms of bowel movements many times in the past few years, I have been to a few places to see a doctor and have taken medicine, but it has not been cured. Mostly in the morning, wake up a few times or after eating, you can go out without time.
