Hello, I have been experiencing constipation since middle school, typically having a bowel movement about once a week.
In recent years, I have occasionally relied on laxatives to help with bowel movements.
There was one instance where I did not have a bowel movement for 15 consecutive days, and I had to take medication to relieve it.
Recently, I noticed that my stools sometimes contain mucus or even fresh blood.
Just yesterday, I passed a significant amount of fresh blood and blood clots.
I would like to ask the doctor if this is a result of long-term medication use, or if not taking medication is causing my inability to have bowel movements.
Could there be other issues with my gastrointestinal tract? I am concerned about the possibility of colon or rectal cancer.
I have had stomach pain since childhood, and at the ages of 26 to 28, I underwent an endoscopy due to stomach pain.
At that time, it was noted that my stomach was slightly inflamed and my bowel movements were poor.
I consulted a doctor who mentioned it might be due to poor intestinal motility.
Overall, the endoscopy process was very uncomfortable, so I have neglected my gastrointestinal and bowel issues over the years.
However, the presence of blood clots this time has made me very anxious.
I would appreciate any advice from the doctor.
Thank you!

Hello: There are various causes of bloody stools, with common ones including colitis, hemorrhoids, and colorectal cancer.
Based on your medical history, unless there is a family history of colitis and you are over 50 years old, the likelihood of colorectal cancer is extremely low.
Your issue seems to primarily stem from hard stools causing friction at the anal area due to constipation.
As for whether the bloody stools could be caused by a gastric issue, a gastric ulcer with significant bleeding can also result in bloody stools; however, patients typically present with symptoms such as upper abdominal pain and dizziness, and the bloody stools would likely decrease as well.
Therefore, it appears that your symptoms are not related to the upper gastrointestinal tract.
If the condition of bloody stools persists without improvement, I recommend that you consult a gastroenterologist for further evaluation.
Thank you! Sincerely, Dr.
Yao Zhenrong, Internal Medicine.

More Info

Understanding blood in stool can be a concerning issue, especially for individuals with a history of gastrointestinal problems. Your symptoms, including the presence of mucus and fresh blood in your stool, as well as the recent occurrence of large amounts of blood and blood clots, warrant careful consideration and prompt medical evaluation.

Firstly, it is essential to recognize that blood in the stool can arise from various sources within the gastrointestinal tract. The most common causes include hemorrhoids, anal fissures, diverticular disease, inflammatory bowel disease (IBD), and colorectal cancer. Given your history of constipation and the use of laxatives, it is possible that the blood you are experiencing could be due to anal fissures or hemorrhoids, which can occur when straining during bowel movements. However, the presence of large amounts of blood and blood clots raises the concern for more serious conditions, such as IBD or even malignancy.

Chronic constipation, as you have described, can lead to significant strain during bowel movements, which may result in the development of fissures or hemorrhoids. These conditions can cause bright red blood to appear on the stool or toilet paper. However, the presence of mucus and the change in your bowel habits, along with the significant bleeding, suggest that there may be an underlying issue that needs to be addressed.

Your previous history of gastrointestinal issues, including gastritis and the discomfort associated with bowel movements, indicates that your gastrointestinal health has been compromised for some time. The fact that you have not sought medical attention for these ongoing issues could lead to the progression of a potentially serious condition. It is crucial to understand that while laxatives can provide temporary relief, they can also lead to dependency and worsen bowel function over time.

Given your symptoms, it is highly advisable to seek medical attention as soon as possible. A thorough evaluation by a gastroenterologist is warranted. This may include a physical examination, a review of your medical history, and potentially diagnostic procedures such as a colonoscopy. A colonoscopy can help visualize the interior of the colon and rectum, allowing for the identification of any abnormalities, such as polyps, inflammation, or tumors.

In addition to a colonoscopy, your doctor may also recommend imaging studies or laboratory tests to assess your overall gastrointestinal health. It is essential to communicate all of your symptoms, including the frequency of your bowel movements, the consistency of your stool, and any associated pain or discomfort.

In summary, while your symptoms may be related to chronic constipation and its complications, the presence of significant blood and blood clots in your stool is concerning and should not be ignored. Early detection and intervention are key to managing any potential gastrointestinal issues effectively. Please prioritize seeking medical care to ensure a comprehensive evaluation and appropriate management of your symptoms. Your health is paramount, and addressing these concerns promptly can lead to better outcomes and peace of mind.
