Treatment Guide
Available treatment options
When it comes to clearing a hard impaction, lubrication is often more effective than simply adding fluid volume. This is why I frequently recommend an Arachis Oil Enema .
It contains peanut oil, which coats the hardened stool, softens it, and lubricates the bowel lining, allowing the mass to slide out with much less straining. Of course, because arachis oil is derived from peanuts, it carries a risk of anaphylaxis for those with nut allergies.
For those patients, we rely on alternatives like saline or phosphate enemas, which draw water into the bowel to flush it out. However, for sheer softening power of rock-hard stool, oil-based enemas are typically my first line of defence.
What to expect from treatment
Realistic expectations are key to a successful enema. Unlike micro-enemas that work in 15 minutes, an oil retention enema is a slow process. It usually needs to be held in the bowel for 1 to 3 hours, or ideally overnight, to properly penetrate the stool.
Here is a crucial clinical pearl that is rarely written on the box: always warm the enema slightly by placing the sealed bottle in a bowl of warm (not hot) water for ten minutes before use.
Administering cold liquid into the rectum causes instant muscle spasms and an overwhelming urge to evacuate immediately, long before the oil has had time to do its job.
A body-temperature liquid is much easier to retain.
Self-care and prevention
Once we have cleared the blockage, prevention is vital. Beyond the standard advice of drinking two litres of water daily and increasing dietary fibre, the physical mechanics of how you sit on the toilet matter immensely.
I always advise patients prone to impaction to use a small footstool in the bathroom. Elevating your knees above your hips straightens out the puborectalis muscle, which normally acts like a kink in a garden hose to keep you continent.
Straightening this anatomical kink reduces the need to strain and helps prevent stool from pooling and hardening in the lower rectum in the future.
