Changes in Stool Size and Shape: What You Need to Know

Decreased stool frequency and thinner, elongated stools?

Hello Doctor: I underwent a colonoscopy in May 2021, and the physician mentioned that I have intestinal adhesions.
Due to my difficulty with bowel movements, I take 3 capsules of MGO daily.
Recently, I caught a cold and took cold medication.
On the first day, my stool became very thin and long (about the size of a pinky finger), and on the second day, the stool volume was low.
I would like to ask if this could be a sign of a pathological change in the colon or if it is related to the intestinal adhesions.
I am a bit worried and would appreciate your clarification.
Thank you, Doctor.

This situation is likely related to diet and cold medication.
As long as there is no further bleeding, it should be fine.
It is recommended to increase the intake of dietary fiber during this period and to shorten the time spent on bowel movements.
If symptoms persist, it is advisable to consult a physician.
If necessary, a colonoscopy can also be arranged.

More Info

Changes in stool size and shape can often be a source of concern for many individuals, especially when there is a known history of gastrointestinal issues, such as adhesions. In your case, having undergone a colonoscopy that revealed intestinal adhesions, it is understandable that you might be worried about changes in your bowel movements.

Firstly, it is important to recognize that stool characteristics can vary significantly based on a variety of factors, including diet, hydration, physical activity, and even medications. The fact that you recently took cold medication could be influencing your bowel movements. Many over-the-counter cold medications can lead to constipation or changes in stool consistency due to their ingredients, which may include antihistamines that can slow down gut motility.

The appearance of your stool being very thin and long, resembling the size of a pinky finger, can be concerning. In general, changes in stool shape can sometimes indicate an underlying issue. For instance, very thin stools can be associated with conditions that cause narrowing of the intestinal passage, such as strictures or tumors. However, given your history of adhesions, it is plausible that these changes could be related to the adhesions affecting the normal passage of stool through the intestines.

Adhesions can lead to partial obstructions, which may cause changes in stool size and shape. If the adhesions are causing a narrowing of the intestinal lumen, this could explain the thin stool. It is also worth noting that the consistency and frequency of bowel movements can be affected by how well the intestines are functioning, which can be influenced by the presence of adhesions.

While it is essential to monitor these changes, it is equally important to consider other factors that could be contributing to your symptoms. For example, dietary changes, such as increased fiber intake or hydration, can significantly impact stool size and consistency. If you have recently changed your diet or if your fluid intake has decreased, this could also explain the changes you are experiencing.

Given your concerns, it is advisable to consult with a healthcare professional, particularly a gastroenterologist, who can evaluate your symptoms in the context of your medical history. They may recommend further diagnostic tests, such as imaging studies, to assess the status of your intestines and the presence of any potential obstructions or other issues.

In summary, while changes in stool size and shape can sometimes indicate a problem, they can also be influenced by a variety of benign factors. Given your history of intestinal adhesions, it is prudent to seek medical advice to rule out any serious conditions and to discuss your symptoms in detail. Regular monitoring and open communication with your healthcare provider are key to managing your gastrointestinal health effectively.
