One day in evening I have semi solid liquid stool. There was a 1st poop that was semi solid stool colored brown then 2nd poop was red color which was little liquid. It was like diarrhea. Little stomach cramps is also der. After 2 hours I have to go to again for stool. Again there was red color liquid semi solid stool. There was a good quantity of red color. Again after 2 hours I have to go to stool again. Now it's semi solid stool colored brown. No red color stool this time. Note:- I have taken reddish in salad in lunch on same day. Another day:- I have gone 2 times for passing stool. Both time it's like liquid semi solid stool color medium to dark brown. No red color stool this time also. I am worrying about red color liquid semi solid stool which was happened on 1st day. Is it blood? Or is it because of reddish? It's in good quantity of red color. And how can we identify that is it because of reddish or blood? Please help me.
