    For the last three weeks, my stool floats in the toilet rather than sink to the bottom. The color is medium brown and comes, without straining, daily. I am 67 years old, take no medication, exercise regularly, and eat a balanced diet.
    Is this alarming?

    Hi Anne

    It may be a sign of steatorrhea – fats in the stool. This can arise for various reasons, some of which are very serious while others are more benign. At three weeks, it seems like the condition may have the potential to be a chronic ailment and this does raise some concerns. Certain conditions are more likely to occur in your age group so in that respect, yes, it may be alarming. You should see your doctor who will then take a stool sample and send it for further analysis. Based on the findings, other investigations may be conducted to help conclusively identify or exclude certain conditions.
