Examine stools: When you say internal bleeding, it is presumed gastrointestinal bleeding. It can be acute or chronic. Acute bleeding can be life threatening, you may see bloody vomiting or rectal bleeding. Chronic bleeds, such as slow bleeding from a peptic ulcer, hemorrhoids, even some cancers, and divertticular bleeds. The blood in the stool can be detected with a simple test.
