When Should You See a GI Doctor for Rectal Bleeding?
A small amount of blood may sometimes have a relatively common cause, but it is important not to assume the cause without appropriate evaluation by a gastroenterologist such as Dr. Khan.
Consider speaking with a healthcare professional when rectal bleeding:
- Keeps returning
- Persists
- Occurs without a known explanation
- Appears mixed with stool
- Is associated with changes in bowel habits
- Occurs with unexplained weight loss
- Is accompanied by persistent abdominal pain
- Occurs with ongoing diarrhea or constipation
- Is associated with unexplained anemia
- Is accompanied by other concerning symptoms
The urgency and appropriate evaluation depend on the amount of bleeding, your symptoms, age, medical history, and other risk factors.
A gastroenterologist for rectal bleeding can evaluate whether your symptoms may be related to the digestive system and whether additional testing is appropriate.
Bleeding That Lasts or Returns
Small amounts of bleeding that continue for more than a few days, keep coming back, or have no clear cause are worth a GI evaluation, even if they seem minor.
Bleeding With Other Symptoms
See a gastroenterologist if bleeding comes with changes in bowel habits, abdominal pain, unexplained weight loss, fatigue, or a low blood count.
When It Is an Emergency
Heavy bleeding, black or tarry stool, dizziness, fainting, or a racing heartbeat need emergency care right away. See emergency warning signs

What Can Cause Rectal Bleeding?
Rectal bleeding is a symptom, not a diagnosis.
Blood may appear on toilet paper, in the toilet bowl, on the outside of stool, or mixed with stool. The appearance alone cannot reliably identify the cause.
Possible causes can include conditions affecting the anus, rectum, colon, or other parts of the digestive tract.
Examples may include:
- Hemorrhoids
- Anal fissures
- Polyps
- Diverticular conditions
- Inflammatory bowel disease
- Infections
- Colorectal cancer
- Other gastrointestinal conditions
This is not a complete list, and symptoms alone cannot determine the cause.
A medical evaluation may be needed to identify the appropriate diagnosis and treatment.
Learn more about GI Symptoms and Conditions.
Bright Red Blood vs. Dark Blood in Stool
The appearance of blood can vary.
Bright Red Blood
Bright red blood may be associated with bleeding closer to the rectum or lower digestive tract, but the appearance of blood alone does not determine the exact source.
Dark or Black Stool
Dark or black stool can have different causes, including certain foods, medications, supplements, or gastrointestinal bleeding.
Black, tarry stool can be a sign of bleeding higher in the digestive tract and may require urgent medical attention.
Seek prompt medical advice when you have unexplained black or tarry stools.
Rectal Bleeding and Hemorrhoids
Hemorrhoids are swollen blood vessels in or around the rectum and anus and can cause symptoms such as:
- Rectal bleeding
- Itching
- Discomfort
- Swelling
However, not all rectal bleeding is caused by hemorrhoids.
Even if you have previously been diagnosed with hemorrhoids, new, persistent, or recurring bleeding should be appropriately evaluated.
Learn more about Hemorrhoid Treatment.
Rectal Bleeding and Changes in Bowel Habits
Rectal bleeding that occurs with changes in bowel habits may require additional evaluation.
Examples include:
- New or persistent constipation
- Ongoing diarrhea
- Alternating diarrhea and constipation
- A significant change in usual bowel patterns
- Changes in stool appearance
Depending on your symptoms and medical history, a GI specialist may recommend further testing.

Blood in Stool and Abdominal Pain
Rectal bleeding accompanied by persistent abdominal pain, unexplained weight loss, or other ongoing symptoms should be medically evaluated.
These symptoms can have many possible causes and do not automatically indicate a serious condition.
However, a gastroenterologist can evaluate the full clinical picture and determine whether further testing is appropriate.
