I’ve been having constipation and thin poo for 2 weeks. 2 weeks ago I started to suffer from constipation. I’ve been trying some medication but it helped very little. Even I feel my stomach is full i can’t poop properly. My poo is very thin and there is very little of it. I suffer from depression as well. But it never happened to me before. I read that thin poo is a symptom of colon cancer. And now I’m very down. I turned 17 three days ago. Must I be afraid?
