Is anybody going to cover that a common phenomenon is that people find blood in their stool after a night of drinking? I've heard of this before, and when you google it a lot of people report the same phenomenon. I found one explanation that said that your blood flow to your liver gets constricted as your liver tries to process the blood to remove alcohol, and then there is a back up of blood, and that back up goes to the rectum, since a third of the arteries from your rectum/lower intestine go to your liver, and the back up of blood sometimes leaks and causes blood in the stool. — Preceding unsigned comment added by 108.170.95.180 ( talk) 14:51, 22 August 2012 (UTC)

I plan to add to this article and revamp the list of causes given under blood in stool. This is a broad category, so in order to do it justice, I will approach several different areas.
Resources The page is currently out of date, with several resources dating from prior to 2010, with some even prior to 2000. I will update these resources, to ensure that the information reflected is more accurate. Additionally, as new information is added, my goal will be to only use resources within the last five years for primary information.
Introduction Currently the introductory paragraph quickly brushes over some topics rather quickly, which are important distinctions in the types of blood found in stool. I plan to edit this paragraph for understanding. I will also add a table to help readers more easily synthesize the information regarding the types of blood: hematochezia, melena, and BRBPR which can originate from outside of the anus(external hemorrhoids/anal fissure). I also plan to make mention of the complications that can occur due to bleeding, which will be a lead in to a section on anemia.
Causes section Rather than provided a list of causes, with no division as to the types of bleeding in the GI tract. I plan to divide the section into bleeds originating from the upper, lower and both portions of the GI tract, in order to help provide some understanding as to what each type of blood may look like in the stool. As a result, there will be a few introductory sentences for each of these sections, as well as the Causes section, in order to orient the reader to those causes.
Diagnosis section This section will be brief, as this page refers to blood in stool as a symptom, rather than as a diagnosis. It is important, however, to consider that the reader may be interested to learn what types of testing exist in order to pursue a diagnosis of the cause of bleeding. This is where the division of the Causes section become more useful. Different types of tests for diagnosis are used for different types of bleeding, usually as it pertains to upper v lower GI tract as the source.
Anemia This is an important complication of copious blood in the stool, and should be mentioned on this page for the sake of thoroughness.
Mimics A short list of substances that may mimic a blood in the stool, particularly things like PeptoBismol, as it mimics old blood in the stool, could also be useful to the reader.
Please let me know your thoughts on my plans for the addition of all this new information to my article. Thanks Sarahguess5 ( talk) 20:00, 20 November 2017 (UTC)

The tests that are considered for evaluation of the passage of blood in the stool is based on characteristic of bleeding (color, quantity) and whether or not the person passing blood has a low blood pressure with elevated heart rate, as opposed to normal vital signs. [1] These tests are combined to determine which of the causes below is the source of bleeding.
Melena is defined as dark, tarry stools, often black in color
[2] due to partial digestion of the
RBCs
Hematochezia is defined as bright red blood seen in the toilet either inside of, or surrounding the stool [2]
Hematochezia is typically presumed to come from the lower portion of the GI tract, and the initial steps of diagnosis include a DRE with FOBT, which if positive, will lead to a colonoscopy [2] [3] [4] [1]. If bleeding is large in volume, the evaluation may also include an EGD [2] [3] [1] [4]. If no source of active bleeding is found on these examinations, a capsule endoscopy may be performed, in order to more closely examine the small bowel, which cannot be seen with the other types of studies [4]. With melena, a DRE with FOBT is often also performed, however the suspicion for a source from the upper GI tract is higher, leading first to the use of EGD with the other tests utilized if no source is identified [3] [4]. The anoscopy is another examination, which can be used as an adjunct to the colonoscopy, which exams the rectum and distal portion of the descending colon [2] [1].
Color | Medical term | Frequency | Quantity | Types of bleeding considered |
---|---|---|---|---|
Bright red | Hematochezia [2] | Occasional | Small | Hemorrhoids [5] [1], inflammatory conditions [1], polyps [1] |
Bright red | Hematochezia [2] | Continous | Large | Upper or lower GI tract source of bleeding as a result of numerous causes [1] (see below), rapid bleeding [1] [3] |
Dark red/black | Melena [2] | Every stool | Mixed with stool | Upper GI tract source [3], peptobismol and iron use can mimic melena [3] |
Mucus may also be found in stool.
A texture described as tarry stool is generally associated with dark black stool seen in partially digested blood. This is generally associated with melena.
Age is an important indicator for the diagnostic workup that is considered for the presence of blood in stool, as a result of the diagnoses that tend to affect each age group. [1]
Age | Group | Types of bleeding considered |
---|---|---|
<20 years | Pediatric | Inherited/autoimmune condition or structural |
20-60 years | Middle aged | Inherited/autoimmune condition, vascular malformation |
>60 years | Elderly | Vascular malformation, liver disease, cancer |

was invoked but never defined (see the
help page).Blood in the stool can come from many sources. The causes range from not harmful to very serious conditions. A common way to divide causes of bleeding is based on the source of bleeding. The GI tract can be divided into upper [1] and lower [2], with some causes of bleeding affecting the entire tract. Blood in the stool often appears different depending on its source, guiding the diagnostic approach of these conditions, however, depending on the rate of bleeding, it can appear different from the typical presentation of the source [3] [4].
The upper GI tract is defined as the organs involved in digestion above the ligament of Trietz and is comprised of the esophagus, stomach, and duodenum [1]. Upper gastrointestinal bleeding is typically characterized by melena, however bright red blood can be seen with active, rapid bleeding [5].
Bleeding of the lower GI tract will typically appear as hematochezia [4] and can vary in degree of seriousness [4]. Slow bleeding from the ascending portion of the colon can result in partial digestion of the blood and the appearance of melena in the stool [3].
The development of blood in stool results from a variety of conditions, which can be divided into major categories of disease process. These broad categories include cancerous processes or abnormal structure of bowel wall, inflammatory disease, colitis caused by infection or medications and vascular compromise [3].
The gut wall is important to the movement of waste products through the GI tract. When compromise occurs at varying points along the tract
This list of diagnoses include diseases in which the wall of the bowel is compromised by disease [3].
Enteritis - inflammation of the small intestine, which may be caused by various forms of as well as by other conditions: [26]

was invoked but never defined (see the

There is also, generally, not a need to place citations in the middle of sentences. We sometimes use them after a comma if you are making a list, but try not to do this in all sentences as it makes it harder to read. Good work so far on your suggestions, I am out of time right now to review this. Please finish going through the article and correct the placement of citations.

Wiki article peer review on blood in stool: The article is very clear and understandable. The lead paragraph is strong and gives me a clear understanding of what blood in the stool is and a brief description of the two main kinds of described blood in the stool (hematochezia and melena). There is, by nature of the topic, lots of medical jargon that had to be used, but there are embedded links when appropriate and terms are defined when appropriate.
Everything in the article is relevant to the topic. If there was previous excess information, it has now been removed, and every part of the article is essential for getting a full, clear picture of blood in the stool.
The pathophysiology and evaluation sections of the article are heavier with medical jargon. In my opinion, this is by necessity. However, it would be difficult for a nonmedical person to read and understand these sections without going to other Wikipedia pages for further definitions. The author did a great job of minimizing confusion by embedding many other wikipedia pages for further clarification, which I think is the best solution to problems understanding medical jargon in this article.
The article is neutral and balanced. There are no statements or words present that would bias the reader toward and particular position. The article is purely informational and provides appropriate references after factual statements. The references provided support the statements where they were cited. The information is summarized nicely from the sources in the Wiki article writer’s own words, and I can see no concern for plagiarism. The majority of the sources were published in the last 5 years but there are some references from 1990—however, the information from these references is concerning history and physical exam, which is information that has not changed and is still relevant to the topic currently.
Things to change or add: I think it could potentially be helpful to provide images of melena and hematochezia. While there are links to both of these words for further information, I think it could add value to this particular article. Also, I think the table in the evaluation section could be simplified a little to make it easier to read.
