Abnormal stool shape?


Dear Doctor,
I have been experiencing frequent abdominal pain over the past two to three months.
Sometimes it is in the lower abdomen, other times in the upper abdomen, and occasionally in the right upper quadrant.
I underwent an ultrasound and gastroscopy around December last year, which only showed mild fatty liver.
Two weeks ago, I had a fecal occult blood test, and the results were normal.
However, I continue to have persistent abdominal pain, and recently, the shape of my stools has been very unusual.
I often feel lower abdominal pain and the urge to defecate, but I can only pass a small amount.
When I do have a larger bowel movement, the shape is very irregular.
I have never experienced anything like this before, and despite undergoing numerous tests, I still have no answers.
I am quite worried.
Could you recommend a good doctor in Taipei? Thank you.

Understanding unusual stool shapes and persistent abdominal pain can be concerning, and it's important to address these symptoms with a comprehensive approach. Based on your description, it seems you have been experiencing abdominal pain for the past few months, with varying locations of discomfort, and you have noticed unusual stool shapes, including thin or ribbon-like stools. You also mentioned having undergone several tests, including an ultrasound and endoscopy, which revealed mild fatty liver, and a recent stool test for occult blood that returned negative.

Firstly, let's discuss the potential causes of your symptoms. Abdominal pain can arise from a variety of gastrointestinal issues, including but not limited to:
1. Irritable Bowel Syndrome (IBS): This is a common functional gastrointestinal disorder characterized by abdominal pain and altered bowel habits, which can include diarrhea, constipation, or a combination of both. IBS can lead to changes in stool shape and consistency.

2. Intestinal Obstruction: A partial obstruction in the intestines can lead to cramping abdominal pain and changes in stool shape. This can be caused by adhesions, hernias, or other structural issues.

3. Inflammatory Bowel Disease (IBD): Conditions such as Crohn's disease or ulcerative colitis can cause abdominal pain and changes in bowel habits. These conditions often require more extensive testing, including imaging studies and possibly colonoscopy.

4. Colorectal Issues: Abnormal stool shapes, especially if they are thin or ribbon-like, can sometimes indicate issues in the colon, such as polyps or tumors. While your recent tests did not show any blood in the stool, it is still important to consider further evaluation if symptoms persist.

5. Dietary Factors: Changes in diet can also affect stool shape and consistency. A diet low in fiber can lead to harder, more compact stools, while a high-fiber diet can result in softer, bulkier stools.

Given that you have already undergone several tests without a definitive diagnosis, it may be beneficial to consult with a gastroenterologist who specializes in digestive disorders. They can perform additional tests, such as a colonoscopy, to visualize the colon directly and rule out any serious conditions.

In terms of managing your symptoms, consider the following:
- Dietary Adjustments: Increasing fiber intake through fruits, vegetables, and whole grains can help regulate bowel movements and improve stool consistency. Staying hydrated is also crucial.

- Stress Management: Stress can exacerbate gastrointestinal symptoms, so incorporating relaxation techniques, such as mindfulness or yoga, may help alleviate some discomfort.

- Regular Follow-ups: Keep a symptom diary to track your abdominal pain and stool characteristics. This information can be valuable for your healthcare provider in determining the next steps in your evaluation.

As for finding a good doctor in Taipei, I recommend looking for a reputable gastroenterology department at a medical center or university hospital. You can also ask for referrals from your primary care physician or seek recommendations from friends or family who have had positive experiences with gastroenterologists.

In summary, while unusual stool shapes and persistent abdominal pain can be alarming, there are various potential causes that can be investigated further. It is essential to work closely with a healthcare provider to determine the underlying issue and develop an appropriate treatment plan. Don't hesitate to seek a second opinion if you feel your concerns are not being adequately addressed.
