Blood surrounded by stool?
Answer:
Bright red blood contained by stool: {lower GI bleed}
hemorrhoids, anal fissures, polyps, ulcerative colitis, bacterial infections (shigella, salmonella, e coli, to name a few)
Dark blood surrounded by stool (maybe black and tarry): {upper GI Bleed)
bleeding gastric ulcers, oesophageal varicies, duodenal ulcer, alcoholic gastritis (to name a few)
he wants a rescope upper and lower within a few hours of this episiode to see any possible causes...
If the blood is bright and red it is possible from near the anus (like hemroids or a fissure). If it is dark it can mean that it is from farther inside. Of course, I hope he is seeing a doctor for this. Since, it can be a sign of colon cancer.
Alcohol can surrounded by fact irritate the esophagus and stomach. As a result the blood could be coming from the stomach. A correct test to see if the stomach is responsible is an endoscopy or Upper-GI testing. (Both are painless and do not require a "prep" to be taken prior like surrounded by a colonoscopy). However, if it bright red blood it is most likely due to an nouns that the colonoscopy would have detected.
Since this have not happened beforehand, it is also plausible that the blood is not related to alochol intake. Perhaps another condition has simply begun - surrounded by which case mind. If you focus on the alcohol aspect, doctors may only consider the liver and not other areas of the body. (For indisputable thorough testing you could also own an abdominal CT scan).
Just be aware that this is NOT normal and a solution should be reach. At the very smallest it should be discovered what is causing this problem. Keep exhausting your medical resources and don't whip a "we don't know, everything is fine" for an answer.
The doctor has merely missed the cause and requirements to look closer to find it. It could be dangerous.

With a middle-of-the-road colonoscopy recently, Ulcerative Colitis/hemmorhoids, etc. are somewhat unlikely (but not eliminate as possibilities). Alcohol use does cause liver change. Liver changes can front to anti-coagulation- making bleeding easier. Make sure he is not taking a Tylenol (acetaminophen) product at the same time or a hulking dose of Aspirin or Ibuprofen. This could cause undemanding bleeding by almost anything going down the GI tract. Have his liver enzymes checked if not done so before-and it never hurts to help yourself to a Milk Thistle tablet or two a day to verbs out a "toxified" liver.
