Gastrointestinal issues


(1) I would like to ask the doctor, I have been experiencing irregular bowel movements for about six months.
Sometimes my stools are pellet-like, and other times they are watery.
Last week, I noticed this issue and visited a clinic for a stool test, which came back normal.
After taking medication, my condition improved, but sometimes I have normal bowel movements one day and then diarrhea the next morning.
Could you please explain what this situation might be? Is there a possibility of colon cancer?
(2) I would like to ask the doctor, two days ago I ate something similar to oily chicken, and as a result, I had stomach pain that night.
After seeing a doctor and taking medication, the abdominal pain went away, but when I woke up in the morning, I had diarrhea that was dark green in color.
(3) Could you please clarify, doctor, if a stool occult blood test could be inaccurate if the stool sample is taken during a bout of diarrhea and the sample volume is very small?

Dr. Chen Qifeng reply Gastroenterology and Hepatology


It is likely a functional gastrointestinal disorder.
It is recommended to have a diet low in oil, low in dairy, and low in irritating foods.
If symptoms persist, at least consider a colon X-ray to rule out any organic lesions.

More Info


Understanding gastrointestinal issues can be quite complex, especially when symptoms are varied and persistent. Based on the information provided, it seems you are experiencing a combination of irregular bowel movements, abdominal pain, and changes in stool consistency and color. Let's break down your concerns and provide some insights.

1. Irregular Bowel Movements: You mentioned having inconsistent bowel habits for about six months, with episodes of both constipation and diarrhea. This fluctuation can be indicative of several conditions, the most common being Irritable Bowel Syndrome (IBS). IBS is a functional gastrointestinal disorder characterized by symptoms like abdominal pain, bloating, and altered bowel habits without any identifiable structural or biochemical abnormalities. Stress, dietary choices, and lifestyle factors often exacerbate these symptoms.
The fact that you experienced improvement after taking medication suggests that there may be a functional component to your symptoms. However, persistent changes in bowel habits warrant further investigation, especially if they are accompanied by alarming features such as significant weight loss, blood in the stool, or severe abdominal pain.

2. Abdominal Pain and Stool Color: You reported experiencing abdominal pain after consuming certain foods, such as oily chicken, followed by greenish diarrhea. The green color of stool can result from several factors, including rapid transit through the intestines (which may not allow enough time for bile to break down completely) or dietary choices (such as consuming green foods or food dyes). If the pain was acute and resolved quickly after medication, it may have been a transient reaction to the food rather than a sign of a serious underlying condition.

3. Fecal Occult Blood Testing: You inquired about the accuracy of fecal occult blood tests when the stool sample is collected during a bout of diarrhea. Generally, these tests are designed to detect hidden blood in the stool, which can be a sign of various gastrointestinal issues, including polyps, hemorrhoids, or malignancies. However, if the stool is very watery and the sample is small, it may not provide a reliable result. It’s crucial to follow up with your healthcare provider for further testing if there are concerns about potential bleeding or other serious conditions.


Recommendations:
- Dietary Adjustments: Consider keeping a food diary to identify any potential triggers that may worsen your symptoms. Reducing intake of high-fat, spicy, or processed foods, as well as caffeine and alcohol, may help alleviate symptoms. Incorporating more fiber gradually can also assist with bowel regularity.

- Hydration: Ensure you are adequately hydrated, especially if experiencing diarrhea. Electrolyte solutions can be beneficial in maintaining hydration levels.

- Stress Management: Since stress can significantly impact gastrointestinal function, exploring stress-reduction techniques such as mindfulness, yoga, or therapy may be beneficial.

- Follow-Up with a Specialist: Given the duration and nature of your symptoms, it would be wise to consult a gastroenterologist. They may recommend further diagnostic tests, such as a colonoscopy, especially if there are any red flags or if your symptoms persist despite conservative management.

In conclusion, while your symptoms may be indicative of functional gastrointestinal disorders like IBS, it is essential to rule out more serious conditions through appropriate medical evaluation. Keeping track of your symptoms and dietary habits will be invaluable in managing your health and communicating effectively with your healthcare provider.
