What Is Blood In Stool A Sign Of When Muscle Strain Is Also An Issue?

Blood mixed with the motion itself suggests that the bleeding is occurring higher up in the gastrointestinal system, for example as the result of peptic ulcers in the duodenum or stomach, or of tumours of the tomach wall. Ulceration in the oesophagus (oesophagitic) or ruptured blood vessels in the oesophagus from excess vomiting are also possibilities.
Is there any accompanying pain?
Pain felt when actually going to the lavatory suggests a problem located within the rectum itself. Haemorrhoids or a fissure ( a split in the sensitive lining here) may be the cause. On the other hand, a well-localized, dull, aching pain in the abdomen occurring when the sufferer is not going to the loo is more suggestive of an inflammation of the bowel ( colitis) , an infection or a bowel tumour.
