May be hemorrhoids.
Detailed Answer:
Hi,
I have gone through your query.
As you have mentioned your brother complains of
blood in stool. This can be due to various reasons like:
Rectal or anal hemorrhoids or anal fissures
Diverticulosis
Upper gastrointestinal bleeding
Peptic ulcer disease
Esophageal varices
colorectal cancer
Inflammatory bowel diseases like
Ulcerative colitis or crohn's disease
A black, tarry stool is likely an ulcer or other problem in the upper part of the digestive tract. Bright red blood or maroon-colored stools usually indicate a problem in the lower part of the digestive tract such as hemorrhoids or
diverticulitis. Hemorrhoids or anal fissures may be associated with pain at the time of passing stool.
Cause of the blood in stool should be found out. And as you have mentioned it is coming out without pressure, most probable site is in rectum.
Colonoscopy, Per
rectal examination and Ultrasound is advised.
Since he is having problem for three months, there have been excessive loss of blood.
Complete blood count should be done.
I advise you to consult a local surgeon asap for proper clinical examination and investigation as you have wasted 3 months of time on medication without knowing the cause.
Hope I have answered your query. If you have any further questions I will be happy to help.
