Enemas and Suppositories Both Provide Constipation Relief
When over-the-counter laxatives and lifestyle remedies fail to relieve difficult constipation, enemas and suppositories are two treatment options doctors may recommend.
What is an Enema?
An enema involves injecting a liquid solution into the rectum to encourage bowel movements. The additional fluid volume stimulates the intestines to contract and push out stool.
Enemas are available in ready-to-use formats at pharmacies or can be custom mixed by doctors for stubborn constipation cases.
What is a Suppository?
A suppository is a solid medication in bullet-shape that you insert into the rectum where it dissolves and triggers a bowel movement through chemical stimulation.
Glycerin, bisacodyl, and polyethylene glycol are common active ingredients. Effects occur in 15 minutes to several hours depending on the type.
Key Differences Between Administering Enemas and Suppositories
While both enemas and suppositories are used rectally to relieve constipation, there are some key differences in how they are administered:
Liquid Solution vs Solid Dose
The main difference is that enemas involve instilling water or liquid solutions into the rectum via an enema bag, bulb syringe or other delivery device. Suppositories use pre-formed solid medications inserted manually with a finger.
Volume Administered
A typical enema administers 100-200 mL of fluid solution into the rectum compared to a suppository which uses a small 4-8 gram solid dose.
Administration Process
Giving yourself an enema has a longer administration process of hanging/filling the bag, lubricating the tip, inserting, infusing all the liquid at the right rate, and removing. Suppository insertion is simpler with just lubricating and pushing the capsule into place.
Comparing Enema and Suppository Effectiveness
Both stimulus-based treatments can effectively induce bowel movements to relieve even severe cases of constipation. Key differences in effectiveness include:
Onset of Action
Enemas tend to produce bowel movements faster than most suppositories with results in 2-15 minutes. Bisacodyl and glycerin suppositories take 15-60 minutes to act in most people.
Mechanism of Relief
Enemas primarily work by increasing the fluid volume in the intestines, triggering contractions to push out stool. Suppositories use irritant chemicals to stimulate bowel movements once dissolved.
Extent of Relief
The larger liquid volume of enemas may stimulate more complete evacuation and relief of built up stool in the colon compared to suppositories.
Safety and Side Effect Considerations
Both treatments are generally safe for periodic use, but certain side effects and risks may occur.
Discomfort During Administration
Inserting an enema tip or suppository too forcefully can cause anal or rectal discomfort, pain or potential injury. Always use proper lubrication and go very slowly.
Electrolyte Imbalance
Frequent or improper use of certain enema solutions can flush out too many bodily electrolytes depleting levels of essential sodium, chloride and potassium for example.
Infection Risk
Improperly sterilizing enema equipment or using tap water can introduce harmful bacteria into the rectum leading to infection. Follow all disinfecting directions carefully.
Bowel Irritation
Overusing stimulant laxative suppositories may irritate the sensitive rectal tissues, especially if diarrhea occurs. Glycerin suppositories tend to be gentlest option.
Professional Guidance Recommended
It’s best to consult a doctor before trying enemas or suppositories to treat difficult constipation cases. They can assess if stimulus-based treatments are medically appropriate and provide guidance on proper administration protocols and safety precautions based on your health status.
With professional input, both enemas and medicated suppositories can provide safe, targeted relief when you need constipation relief fast.
FAQs
Are enemas or suppositories more effective for constipation?
Both can be highly effective, but enemas may stimulate more complete evacuation and relief by instilling more fluid to induce bowel contractions. Suppositories act locally where inserted.
Do enemas and suppositories have side effects?
Used occasionally they are well tolerated, but overuse can cause electrolyte imbalance, infection, bowel irritation, nausea or cramps. Improper administration may cause discomfort or anal/rectal injury.
Which works faster - an enema or suppository?
Most enemas tend to produce bowel movements within 0-15 minutes after administration. Bisacodyl and glycerin suppositories generally take 15-60 minutes to stimulate a movement once inserted.
Can I give myself an enema or suppository at home?
Yes, both treatments are available for at-home use to relieve constipation. Follow all package instructions carefully and talk to your doctor if you have any health conditions or experience worrisome side effects.
