The digestive system is made up of a long tube called the gastrointestinal (GI) tract. If the GI tract is injured in any way, it may lead to bleeding. The following symptoms could be an indication of whether the GI tract has been bleeding:
Pain or tenderness in the stomach area;
Pain or tenderness lower down;
Change in bowel habits;
A feeling of being permanently exhausted or run down.
SelfDiagnosis supply two types of bowel disorder tests, both of which are extremely easy to use and can detect the presence of blood in the stool.
