Blood and Mucus in Stool: Gastrointestinal Concerns Explained

Blood in stool, mucus, and gastrointestinal issues?

Hello, Doctor.
I would like to ask you three questions.

1.
In the past, my bowel movements were mostly unformed and diarrhea-like.
However, in the last 2-3 months, they have suddenly become more formed, and at the beginning of the bowel movement, the stool is somewhat hard, but I do not experience constipation.
Is this considered normal?
2.
For the past two months, I have been experiencing gastrointestinal discomfort and frequent abdominal pain, which sometimes leads me to use the restroom.
After a bowel movement, I feel significantly relieved, but after a while, the discomfort returns.
Since last month, I have noticed what seems to be a thrombosed vein at the anal opening, which causes pain during bowel movements and a sensation of a foreign body in the anus.
I have also experienced recurrent anal fissures, and I notice bright red material on the surface of my stool, which disperses in the toilet water.
Could this be caused by hemorrhoids and anal fissures?
3.
This week, I have occasionally felt a sensation of being unable to pass gas, but after some time, I am able to do so.
My stomach feels bloated, and sometimes I have a sensation of incomplete bowel movements.
If I return to the toilet, I find that only a small amount of mucus is expelled.
Could this be indicative of gastrointestinal inflammation or functional dyspepsia? I sometimes notice food remnants in my stool.
In the past month, I underwent an upper endoscopy, fecal occult blood test, and cancer marker tests.
The endoscopy showed inflammation in the duodenum, the fecal occult blood test was negative, and the cancer marker levels were within the normal range.
I also had a rectal examination, but the doctor did not mention anything specific, only prescribing an anal suppository, ointment for anal fissures, and a stool softener.

1.
Bowel habits are often influenced by diet, exercise, lifestyle, and even psychological stress.
Increasing dietary fiber intake can help form more regular stools, and if it does not cause any significant disruption to daily life, it may not be a concern.

2.
If there are symptoms such as abdominal pain or a feeling of incomplete evacuation, even if fecal occult blood tests are normal, a colonoscopy should be considered.
Hemorrhoids and anal fissures can cause pain and bleeding during bowel movements, but they do not typically cause abdominal pain or changes in bowel habits.
3.
A colonoscopy can be considered to rule out any colonic lesions.
Once it is confirmed that the colon is normal, medications can be prescribed to address symptoms of irritable bowel syndrome, which may help alleviate your concerns.

Understanding the presence of blood and mucus in stool can be concerning, and it’s important to address these symptoms with a comprehensive approach. Based on your questions, let’s break down each concern and provide some insights.

1. Changes in Stool Consistency: You mentioned that your stool has transitioned from being unformed to more formed, albeit with some hardness at the beginning. This change can be normal, especially if you are not experiencing constipation. Factors such as dietary changes, hydration levels, and stress can influence stool consistency. If your stool is formed but not hard, and you are able to pass it without straining, this is generally considered a normal variation. However, if you notice persistent changes or discomfort, it would be wise to consult a healthcare provider.

2. Symptoms of Pain and Blood: The presence of pain during bowel movements, along with the sensation of a "thrombus" or lump at the anal area, suggests the possibility of hemorrhoids or anal fissures. Hemorrhoids can cause bright red blood on the surface of the stool or on toilet paper, and they can lead to pain and discomfort, especially during bowel movements. Anal fissures, which are small tears in the anal lining, can also cause sharp pain and bleeding. Given your description of recurring pain and the presence of red material in your stool, it is likely that these conditions are contributing to your symptoms. It’s essential to manage these issues with appropriate treatments, such as topical medications, stool softeners, and dietary adjustments to prevent straining.

3. Bloating and Mucus in Stool: The sensation of bloating and the feeling of incomplete evacuation can be indicative of gastrointestinal issues such as functional dyspepsia or inflammatory bowel conditions. The presence of mucus in the stool can occur in various conditions, including irritable bowel syndrome (IBS) or infections. Since you have undergone a gastroscopy that revealed duodenal inflammation and have had negative results for occult blood and cancer markers, it’s reassuring that serious conditions have been ruled out. However, the ongoing symptoms suggest that you may be experiencing a functional gastrointestinal disorder or mild inflammation. Dietary modifications, such as increasing fiber intake, staying hydrated, and possibly avoiding trigger foods, can help alleviate these symptoms.

In summary, your symptoms of changes in stool consistency, pain during bowel movements, and bloating with mucus are likely interconnected. The findings from your recent medical evaluations are encouraging, but ongoing management is essential. Here are some recommendations:
- Dietary Adjustments: Increase fiber intake gradually to help with stool formation and prevent straining. Ensure adequate hydration.

- Topical Treatments: Continue using the prescribed ointments for hemorrhoids and fissures to promote healing and reduce discomfort.

- Monitoring Symptoms: Keep track of your symptoms, including any changes in bowel habits, pain levels, and the presence of blood or mucus. If symptoms persist or worsen, follow up with your healthcare provider for further evaluation.

- Follow-up Care: Regular follow-ups with your gastroenterologist or colorectal specialist can help monitor your condition and adjust treatment as necessary.

It’s crucial to maintain open communication with your healthcare team about your symptoms and any changes you experience. They can provide tailored advice and interventions based on your specific situation.
