Defecation
I have been experiencing constipation for the past two weeks, and there is bleeding from the anus after bowel movements, which is fresh blood (I thought it might be hemorrhoids or anal fissures).
However, this morning during a bowel movement, I expelled a deep green, greasy substance that floated on the surface of the water, which startled me.
Could you please tell me what the issue might be? Which specialist should I see? Thank you for your response.

Hello:
1.
The most common causes of blood in the stool are indeed hemorrhoids or anal fissures.
If the symptoms are recurrent or persistent, it is advisable to consult a colorectal surgeon.
2.
The color of feces primarily comes from bile, which contains bilirubin and biliverdin, often giving stool a normal yellow-green color.
When feces are pushed into the colon, biliverdin is reduced to bilirubin, turning the stool yellow.
However, if there is insufficient water intake or slowed intestinal motility, the color of bile can become concentrated, resulting in dark brown stool.
Conversely, if intestinal motility is too fast, bile pigments may not be metabolized by bacteria in time, leading to the original dark green or green color.
Additionally, consuming excessive green fruits and vegetables can also result in green stool.
Therefore, deep green stool is likely caused by rapid intestinal motility leading to bile.
If this color of stool occurs frequently, it is recommended to consult a gastroenterologist.
Wishing you good health,
Dr.

More Info
When it comes to bowel issues, particularly those involving symptoms like constipation, rectal bleeding, and unusual stool characteristics, it is crucial to approach the situation with caution and seek appropriate medical advice. Your symptoms, including fresh blood after bowel movements and the recent occurrence of deep green, oily stool, warrant immediate attention from a healthcare professional, specifically a gastroenterologist.
Understanding Your Symptoms
1. Constipation and Rectal Bleeding: The presence of fresh blood after bowel movements often indicates a problem in the lower gastrointestinal tract. Common causes include hemorrhoids (piles), anal fissures, or more serious conditions such as diverticular disease or colorectal polyps. Hemorrhoids and anal fissures are typically associated with straining during bowel movements, which can occur with constipation.
2. Deep Green, Oily Stool: The appearance of deep green, oily stool that floats can suggest malabsorption issues. This could be due to a variety of factors, including dietary changes, gastrointestinal infections, or conditions affecting the pancreas, such as pancreatitis or pancreatic insufficiency. The oily nature of the stool indicates that fat is not being absorbed properly, which can lead to steatorrhea (fatty stools).
When to Seek Help
Given the combination of your symptoms, it is advisable to consult a gastroenterologist. They specialize in diagnosing and treating conditions related to the digestive system, including the esophagus, stomach, intestines, liver, gallbladder, and pancreas. Here are some steps you should consider:
1. Schedule an Appointment: Contact a gastroenterology clinic as soon as possible. Given the presence of rectal bleeding and the unusual stool characteristics, it’s essential to get a professional evaluation.
2. Prepare for Your Visit: When you see the gastroenterologist, be prepared to discuss your symptoms in detail. This includes the frequency and consistency of your bowel movements, any dietary changes, medications you are taking, and any other symptoms such as abdominal pain, weight loss, or changes in appetite.
3. Diagnostic Tests: The doctor may recommend several tests to determine the underlying cause of your symptoms. These could include:
- Stool Tests: To check for infections, malabsorption, or blood.
- Colonoscopy: This procedure allows the doctor to view the inside of your colon and rectum, helping to identify any abnormalities such as polyps, inflammation, or tumors.
- Imaging Studies: Such as an abdominal ultrasound or CT scan, to assess the organs involved in digestion.
Additional Considerations
- Dietary Adjustments: While waiting for your appointment, consider keeping a food diary to track what you eat and any corresponding symptoms. This can help identify potential triggers.
- Hydration and Fiber: Ensure you are drinking plenty of water and consuming a diet rich in fiber to help alleviate constipation. However, if you are experiencing significant discomfort or changes in your bowel habits, it’s best to avoid self-treatment until you have seen a doctor.
- Avoiding Over-the-Counter Medications: While it might be tempting to use over-the-counter laxatives or stool softeners, these can sometimes exacerbate the problem or mask underlying issues. It’s best to consult with your healthcare provider before starting any new medications.
Conclusion
In summary, your symptoms of constipation, rectal bleeding, and the recent appearance of deep green, oily stool are concerning and should not be ignored. Seeking help from a gastroenterologist is the best course of action to ensure a thorough evaluation and appropriate treatment. Early intervention can lead to better outcomes and help address any underlying conditions effectively.
