Stool color light grey to a very light brown could indicate which condition?

• A. Renal failure
• B. Intestinal polyps
• C. Gallbladder disease
• D. Celiac disease

Answer: (C)

Pale, greyish stool happens when bile pigments aren’t reaching the intestines. Bile from the liver, stored in the gallbladder, normally colors stool brown. If bile flow is blocked—such as by gallstones or other gallbladder/biliary duct issues—the stool becomes light in color. That’s why gallbladder disease best explains this stool appearance among the options. Renal failure doesn’t change stool color, intestinal polyps don’t typically alter stool color, and celiac disease causes fat malabsorption (often with greasy, bulky stools) rather than a classic pale, bile-related stool.
