Orange Stool: Causes and When to Seek Medical Advice - Gastroenterology and Hepatology

Orange stool can be a concerning symptom for many individuals, as it may indicate underlying issues within the digestive system. However, it is essential to understand that the color of stool can be influenced by various factors, including diet, medications, and gastrointestinal health.

In your case, the orange-red color of your stool could indeed be related to your recent dietary choices. Foods like pumpkin, which is rich in beta-carotene, can impart an orange hue to the stool. Similarly, if you consumed items like sweet potatoes or carrots, these could also contribute to the coloration. Fast food items, such as those from a "香吉士" (which I assume refers to a fast-food chain), may contain artificial coloring or ingredients that could alter stool color as well. Therefore, it is quite plausible that your recent meals are the primary reason for the orange tint in your stool.

Regarding your concern about potential bleeding in the digestive system, it’s important to note that blood in the stool typically presents as red or black, depending on where the bleeding originates. Bright red blood usually indicates bleeding from the lower gastrointestinal tract, while black, tarry stools suggest bleeding from the upper gastrointestinal tract. Since you mentioned that the stool does not resemble blood, it is less likely that there is a significant bleeding issue. However, if you notice any changes in your stool color that persist or are accompanied by other symptoms such as abdominal pain, changes in bowel habits, or weight loss, it would be prudent to seek medical advice.

As for your previous colonoscopy in September 2018, if no abnormalities were found at that time, it is generally recommended to follow up with screening colonoscopies based on your risk factors and the guidelines set by health organizations. For average-risk individuals, a colonoscopy is typically recommended every ten years. However, if you have a family history of colorectal cancer, personal history of polyps, or other risk factors, your doctor may suggest more frequent screenings. Given that it has been nearly three years since your last colonoscopy, it would be wise to discuss with your healthcare provider whether you should schedule another screening, especially if you have any new symptoms or concerns.

In summary, the orange color of your stool is likely related to your diet, particularly the consumption of pumpkin and possibly other foods. It is less likely to indicate bleeding, especially since you do not see blood in your stool. However, if you have ongoing concerns or if your symptoms change, consulting with a healthcare professional is always the best course of action. Additionally, consider discussing the timing of your next colonoscopy with your doctor to ensure you are adhering to appropriate screening guidelines.
