I'm 19, going on 20, and over the last three or so weeks have found blood in with my poo when I wipe my bottom. My diet since around Christmas admittedly hasn't been great, with me drinking lots of alcohol and eating lots of food in between. I also have an iguinal hernia, which could be the cause of this problem. I tend to feel constipated quite often during the day and have gone from pooing just once a day to two or three times a day. There's no pain involved when I poo, but it's really concerning me because my diet hasn't been good at all of late and my nan has recently just died from colon cancer, and had blood in her stool just before she died.
