Changes in bowel habits

Hello Dr.
Chen: A few days ago, after having a bowel movement, I noticed blood on the toilet paper, but there was no blood in the stool itself.
In the following days, I felt the urge to have a bowel movement but could only pass soft, thin stools, and I couldn't have a complete bowel movement like before the bleeding.
One day, I experienced cramping abdominal pain and passed watery stools.
I exercise four days a week for over 30 minutes each time, and I drink water normally.
I only eat lunch and dinner each day, occasionally having fried foods.
What could this situation be? Thank you.

Hello, based on the symptoms, it appears to be gastroenteritis causing soft and watery stools, with occasional mild rectal bleeding, which is not serious.
It is recommended to avoid oily, dairy, and irritating foods.
If the watery stools do not improve, you may consult a gastroenterologist.
Wishing you safety and health.
Sincerely, Dr.
Chi-Feng Chen, Attending Physician, Department of Gastroenterology, Taoyuan Hospital, Ministry of Health and Welfare.

More Info

Understanding changes in bowel movements can be concerning, especially when accompanied by symptoms such as blood on toilet paper or changes in stool consistency. Based on your description, it seems you are experiencing a combination of symptoms that may be related to several factors, including diet, exercise, and possibly underlying gastrointestinal issues.

Firstly, the presence of blood on the toilet paper, even if not directly on the stool, can indicate a few potential issues. It could be as simple as hemorrhoids, which are swollen veins in the rectal area that can bleed during bowel movements, especially if the stool is hard or if there is straining involved. Another possibility could be anal fissures, which are small tears in the lining of the anus that can also cause bleeding and discomfort.

The change in your bowel habits, specifically the transition to softer, thinner stools, could be influenced by several factors. Regular exercise is generally beneficial for gastrointestinal health, as it promotes better digestion and bowel regularity. However, if your diet is limited to just two meals a day and occasionally includes fried foods, this could lead to irregular bowel movements. A diet low in fiber can contribute to softer stools and may not provide enough bulk for a healthy bowel movement. It's essential to ensure that you are consuming adequate fiber from fruits, vegetables, whole grains, and legumes to support healthy digestion.

Additionally, the occurrence of abdominal cramping and diarrhea-like stools could suggest a gastrointestinal disturbance, such as irritable bowel syndrome (IBS), which is often exacerbated by stress and dietary choices. Stress can significantly impact gut health, leading to symptoms like cramping, changes in bowel habits, and even diarrhea. Given that you mentioned exercising regularly and maintaining hydration, it would be beneficial to evaluate your overall diet and consider incorporating more fiber-rich foods.

If the symptoms persist or worsen, it is crucial to seek medical attention. A healthcare provider may recommend further evaluation, such as stool tests or imaging studies, to rule out any serious conditions, including inflammatory bowel disease (IBD) or colorectal cancer, especially if there is a family history of such diseases. While your family history may not indicate a direct risk, it is always prudent to be vigilant about any significant changes in your health.

In summary, while your symptoms could be related to benign conditions such as hemorrhoids or dietary factors, it is essential to monitor your symptoms closely. If you continue to experience blood, significant changes in bowel habits, or abdominal pain, please consult a healthcare professional for a thorough evaluation and appropriate management. Remember, maintaining a balanced diet rich in fiber, staying hydrated, and managing stress are key components of gastrointestinal health.
