Clinical FAQs & Expert Guidance
Frequently asked clinical questions, privacy architecture, and digestive wellness guide.
1How accurate is AI stool image classification compared to a doctor's assessment?
Our on-device computer vision models are calibrated against hundreds of peer-reviewed gastroenterology reference images using the Bristol Stool Form Scale. While clinical evaluation by a physician remains the diagnostic gold standard, our local inference engine provides over 90% classification consistency for shape, texture, and color segmentation without ever uploading your private photos.
2Do my photos get uploaded to a cloud server or stored anywhere?
No. All inference executes directly inside your browser sandbox via WebAssembly and TensorFlow.js. Zero bytes of image data ever leave your device or reach our servers. Only the resulting numerical metric (e.g. Bristol Type 4, Brown) is saved to your account if you choose to record it.
3What do unusual stool colors like green, yellow, or black indicate?
Stool color shifts reflect dietary intake and digestive transit speed. Green usually signals rapid transit or rich leafy vegetables; yellow often indicates excess dietary fat or malabsorption; black or tarry stools can signal upper gastrointestinal bleeding or iron supplementation. If abnormal colors persist for more than 48 hours without dietary cause, consult your doctor.
4How often should a healthy adult have a bowel movement?
Clinical gastroenterology defines normal bowel frequency anywhere between 3 times per day to 3 times per week, provided the consistency remains within Bristol Types 3 or 4 without painful straining or urgency.
5Can tracking stool consistency help manage IBS or IBD?
Yes. Objective daily records of Bristol scores, color, and transit speed provide gastroenterologists with critical longitudinal data to distinguish IBS subtypes (IBS-C, IBS-D, IBS-M) and evaluate dietary FODMAP protocols.
6What is the difference between Bristol Type 3 and Type 4?
Type 3 is sausage-shaped with visible surface fissures (healthy, slightly firmer), whereas Type 4 is completely smooth, supple, and snake-like. Both are medically considered normal, with Type 4 representing the optimal hydration gold standard.
7When should I seek immediate medical attention for stool symptoms?
Seek prompt medical care if you observe frank red blood in your stool, jet-black tarry stools (melena), unexplained rapid weight loss, severe nocturnal abdominal pain, or watery diarrhea accompanied by high fever lasting more than 48 hours.
