Does anyone know the effect of taking glycerine suppositories daily to achieve regularity? I have been a D type for yrs, but recently became D/C. Though the C is not terrible for me, it can lead to the D, which is. My mother, who is in her nineties, has been using a glycerince suppository every morning for 40 yrs, with no apparent ill affects. She doesn't have ibs but liked to go before leaving the house. I am tempted to try this, in order to avoid the C which can lead to urgency and D. Any thoughts will be appreciated.
