Flat Stool: What It Means for Your Digestive Health

The stool is flat-shaped?

Hello Dr.
Chen: I have been concerned about my bowel movements over the past six months.
The symptoms are as follows: I have undergone gallbladder removal surgery and rubber band ligation for internal hemorrhoids.
I drink 2 to 3 bottles of Yakult daily.
I have regular bowel movements every day, which are soft but formed, yellow or yellow-brown in color.
However, the first 15 to 20 centimeters of my stool is slightly flattened, resembling an oval shape rather than a cylindrical form, while the stool beyond 20 centimeters becomes very flat.
I have already undergone both a flexible sigmoidoscopy and an anoscopy, both of which were normal.
Is this pattern of bowel movements normal for me? Could it indicate the presence of colorectal polyps? I would appreciate your clarification on my concerns.
Thank you!

Hello, after gallbladder removal, the main issue is the digestion of fats; generally, it is advisable to reduce the intake of greasy foods.
As for your symptoms, if the endoscopy shows no issues, it is primarily a problem of poor function in the colon and rectum.
Making slight adjustments to your diet and developing good bowel habits is recommended.
Additionally, performing pelvic floor exercises can strengthen the function of the rectum and anus.
Wishing you good health, Dr.

More Info

Understanding the characteristics of stool can provide valuable insights into digestive health. In your case, the observation of flat or oval-shaped stools, especially if they are consistently flat over a period of time, can be concerning. However, it is essential to consider various factors before jumping to conclusions.

Flat stools can sometimes indicate a narrowing of the intestinal passage, which may be caused by several conditions, including but not limited to, strictures, inflammation, or even the presence of polyps. Since you have undergone gallbladder removal and have had a history of hemorrhoid banding, it is crucial to monitor any changes in your bowel habits closely. While the normal appearance of your stool is generally a good sign, the change in shape could warrant further investigation.

In your case, the fact that you have had a colonoscopy and an anal examination that returned normal results is reassuring. These procedures are effective in ruling out significant issues such as colorectal cancer or large polyps. However, if you are still concerned about the shape of your stool, it may be beneficial to discuss this with your healthcare provider. They may recommend additional imaging studies or tests to ensure that there are no underlying issues that need to be addressed.

Dietary habits can also play a significant role in stool formation. Consuming a diet rich in fiber, including fruits, vegetables, whole grains, and legumes, can help maintain healthy bowel movements. Since you mentioned drinking yogurt drinks, which can be beneficial for gut health due to their probiotic content, it may also be helpful to incorporate more fiber-rich foods into your diet. Fiber helps to bulk up the stool and can improve its consistency, potentially leading to a more typical cylindrical shape.

Additionally, hydration is crucial for digestive health. Ensuring that you drink enough water throughout the day can help soften the stool and promote regular bowel movements. If you are experiencing any other symptoms, such as abdominal pain, changes in appetite, or weight loss, it is essential to report these to your doctor, as they could indicate a more serious condition.

In summary, while flat stools can be a cause for concern, especially when they persist, your previous normal examinations are a positive sign. It is essential to maintain a balanced diet rich in fiber, stay hydrated, and continue monitoring your symptoms. If you have ongoing concerns or if your stool shape changes further, do not hesitate to reach out to your healthcare provider for further evaluation. They can provide personalized advice and determine if any additional tests are necessary to ensure your digestive health remains optimal.
