Hi,
I am a seventeen year-old female with a family history of colon cancer, diabetes, and varicose veins. Great start, I know.
Anyway, I play sports actively and eat quite well, weighing in at 58kg. Problem is, I've had diarrhoea for a few days now, but it's not severe - it's like my colon is down-sizing. I've also been experiencing stomach cramps, and as of this morning my stools have been red/maroon in color. I went to the bathroom just now and the maroon color was consistently distributed throughout the stool. I am very worried about what this could be, and regarding my family history am convinced I should visit a doctor. Could you give me any advice about what this could be? I've researched stool samples and colon cancer as well as hemorrhoids, and have not eaten any foods that have a red coloring in days, but I'm still unsure about the cause.
