Abdominal issues?


Hello doctor, a few days ago I visited a physician due to blood in my stool.
After a digital rectal examination, the doctor indicated it was a tear and prescribed a suppository, after which there was no further bleeding.
However, I have started experiencing abdominal pain over the past two days, with sudden, intermittent pain in various locations.
Do I need to undergo a colonoscopy? I am a bit anxious about whether this could be a more serious condition, as I had an abdominal CT scan six months ago that showed no abnormalities.

Dr. Ke Fangxu reply Surgery


Although the probability of developing colorectal cancer at the age of 20 is not zero, it is generally very low.
Based on your description, it seems more like hemorrhoidal bleeding.
It is recommended to maintain a light diet and good lifestyle habits, while avoiding spicy, irritating, and greasy foods.
Increasing dietary fiber intake can also be beneficial.
If symptoms persist without improvement, you should consult a physician for medication or consider undergoing a colonoscopy.

When it comes to understanding abdominal pain and determining whether a colonoscopy is necessary, there are several factors to consider. Based on your recent experiences, including the presence of blood in your stool and subsequent abdominal pain, it is essential to approach this situation with caution and thoroughness.

Firstly, the presence of blood in your stool, even if it was attributed to a superficial tear or hemorrhoids, is a significant symptom that warrants further investigation. While the initial diagnosis may have been benign, any recurrence of symptoms, such as abdominal pain, should not be overlooked. Abdominal pain can arise from various sources, including gastrointestinal issues, infections, or even complications from previous conditions.

In your case, the fact that you have experienced sudden, intermittent abdominal pain in conjunction with a prior episode of rectal bleeding raises a red flag. Although your CT scan six months ago showed no abnormalities, conditions can develop or change over time. Therefore, it is crucial to monitor your symptoms closely.

A colonoscopy is a valuable diagnostic tool that allows for direct visualization of the colon and rectum. It can help identify various conditions, including polyps, inflammatory bowel disease (IBD), diverticulosis, and colorectal cancer. Given your symptoms and the history of rectal bleeding, a colonoscopy could provide clarity and peace of mind. It is particularly important if you have risk factors such as a family history of colorectal cancer or if you are over the age of 45, as recommended screening guidelines suggest.

In addition to the colonoscopy, consider discussing with your physician the possibility of other diagnostic tests that may be appropriate based on your symptoms. These could include blood tests to check for signs of infection or inflammation, stool tests to rule out infections or parasites, and imaging studies if indicated.

It is also essential to consider the nature of your abdominal pain. If the pain is severe, persistent, or accompanied by other concerning symptoms such as fever, weight loss, or changes in bowel habits, it is crucial to seek medical attention promptly. These could be signs of a more serious underlying condition that requires immediate intervention.

In summary, while the initial assessment may have indicated a benign cause for your symptoms, the recurrence of abdominal pain and the history of rectal bleeding suggest that further evaluation is warranted. A colonoscopy could be a prudent step to ensure that any potential issues are identified and addressed early. Always communicate openly with your healthcare provider about your concerns and symptoms, as they can guide you in making informed decisions about your health. Remember, early detection and intervention are key to managing gastrointestinal health effectively.
