Once some stool leaves, more will follow. Mineral oil works in the same way. Stimulant laxatives work by stimulating the muscles of your colon to contract. Not surprisingly, they can also give you cramps. Stimulant laxatives are generally not a good idea to use except in rare circumstances since regular use can alter your normal gut function and remove the normal urge to defecate.
Enemas work by expanding the rectum and flush out stool.
These should also be used very rarely, if at all, unless recommended by your physician. Visit our online store for products related to this guide.
