Finding metformin in your stool doesn’t automatically mean a problem. Many factors influence absorption. However, if you suspect undigested metformin, visual inspection alone is insufficient. Metformin tablets are typically white or off-white and somewhat oblong. Look for these characteristics. However, other stool components can resemble metformin.
Color and Shape Clues
Undigested food particles, particularly pills or capsules from other medications, may be similar in size and shape. Compare the suspect particle to known metformin tablets. Color variation within the stool itself is common. The presence of white specks could stem from calcium or other dietary factors. Consider the foods you ate recently; this can help rule out certain possibilities.
Seeking Professional Guidance
If you frequently observe what you believe to be undigested metformin, consult your doctor or pharmacist. They can help determine if incomplete absorption is a concern and may adjust your dosage or suggest alternatives. Accurate identification requires professional analysis, not self-diagnosis. A complete blood test measuring metformin levels will provide a more precise assessment of your medication absorption.
