Celiac stool is often light tan or gray.
In individuals with untreated celiac disease, changes in stool color and consistency are common due to maldigestion and malabsorption of nutrients. Diarrhea is a prevalent symptom, affecting 45-85% of patients. This diarrhea often results in stools that appear:
- Light tan or gray: The altered color is due to impaired bile absorption. Bile normally gives stool its brown color.
- Oily or frothy: The presence of undigested fat can give the stool an oily or frothy appearance.
- Watery or semiformed: The consistency can range from watery to semiformed, reflecting the impaired absorption of fluids.
It's important to note that changes in stool color can also be caused by other factors, so it is essential to consult a healthcare professional for proper diagnosis and treatment if you experience persistent changes in stool color or consistency.
