Questions about stool shape?
Hello Dr.
Tsai: A few days ago, I experienced rectal bleeding after straining during a bowel movement.
For the next few days, I noticed a small amount of blood when I strained again, and I had difficulty sitting normally due to anal pain, which resolved after about three days.
Today, without the urge to defecate, I strained to have a bowel movement and closely observed the shape of the stool.
I found that the color was normal and it was formed, with a diameter of about 2 centimeters.
However, one side had a flat indentation approximately 1 centimeter wide.
I would like to know if this shape is normal.
Thank you!

Hello: This should still be considered a normal phenomenon.
However, if there is continuous bleeding, it is recommended to consult a colorectal specialist.

When it comes to stool shape and the presence of blood, it’s essential to understand the potential implications for your health. Based on your description, it seems that you experienced some rectal bleeding after straining during a bowel movement, which can be concerning. Let's break down the situation and discuss when you should be worried and what steps you can take.
Firstly, the presence of blood in your stool, especially after straining, is often associated with conditions such as hemorrhoids or anal fissures. Hemorrhoids are swollen veins in the rectal area that can bleed when irritated, particularly during bowel movements. Anal fissures, on the other hand, are small tears in the lining of the anus that can occur due to passing hard stools or straining. Both conditions can cause pain and discomfort, and they are generally not serious but can be quite bothersome.
The fact that you experienced blood after straining and that it has continued to occur, albeit in smaller amounts, suggests that there may still be some irritation in the anal area. The absence of pain after three days is a positive sign, as it may indicate that any irritation is healing. However, if you continue to see blood, even in small amounts, it’s essential to monitor the situation closely.
Regarding the shape of your stool, a normal stool is typically cylindrical and can vary in size. The fact that your stool is about 2 cm in diameter and has a flat indentation on one side could be due to several factors. It might be a result of the stool being compressed against the rectal walls or due to the way it passed through the anal canal. While variations in stool shape can occur, if you notice persistent changes, especially if accompanied by other symptoms like pain, significant changes in bowel habits, or continued bleeding, it would be wise to consult a healthcare professional.
In general, here are some guidelines on when to seek medical attention regarding stool shape and the presence of blood:
1. Persistent Bleeding: If you notice blood in your stool consistently over several days, or if the bleeding increases in volume, you should seek medical advice.
2. Severe Pain: If you experience severe pain during bowel movements or in the anal area, it’s important to consult a doctor.
3. Changes in Bowel Habits: If you notice significant changes in your bowel habits, such as diarrhea or constipation lasting more than a few days, this warrants a medical evaluation.
4. Other Symptoms: If you experience additional symptoms such as weight loss, fatigue, or changes in appetite, these could indicate a more serious condition and should be evaluated by a healthcare provider.
5. Family History: If you have a family history of gastrointestinal diseases, it’s prudent to be more vigilant about any changes in your bowel habits or stool characteristics.
In conclusion, while occasional blood in the stool after straining can be due to benign conditions like hemorrhoids or fissures, it’s crucial to monitor your symptoms. Maintaining a healthy diet rich in fiber, staying hydrated, and avoiding excessive straining during bowel movements can help prevent these issues. If your symptoms persist or worsen, please consult a healthcare professional for a thorough evaluation and appropriate management. Your health is paramount, and it’s always better to err on the side of caution when it comes to gastrointestinal symptoms.
