Colonic vs. enema
Colonic vs. Enema: What’s Actually Different?
If an enema made you poop but you still feel backed up, a colonic is a very different process.
An enema and a colonic both introduce fluid through the rectum. That is the similarity. What happens after the fluid enters is very different.
A typical small-volume cleansing enema gives you one limited amount of fluid. You hold it briefly, then move to the toilet and have a bowel movement.
At Iowa Colonics, a colonic is a 45-to-60-minute process of gradual filling and releasing. Warm, filtered water enters gradually. Water has time to contact stool. Your colon fills. Your body releases water, gas and stool through enclosed tubing while you remain on the treatment table. Then another gradual fill can begin.
Enema: one administration, then evacuate. Colonic: fill, soften, release, then repeat throughout the session.
What Happens With a Typical Small-Volume Enema?
A typical over-the-counter cleansing enema is designed to produce a bowel movement quickly.
A current adult Fleet saline enema delivers 118 mL of fluid. You administer that fluid once. You hold it for the period directed by the product. Then you move to the toilet and evacuate.
Fleet states that its saline enema usually produces a bowel movement within 1 to 5 minutes.
- Fluid goes in once.
- You wait briefly.
- You go to the toilet and evacuate.
Not every enema is exactly the same. Some enemas use different solutions, different amounts of fluid or different retention times. But a typical small-volume OTC cleansing enema is still a finite administration.
What Happens During a Colonic?
A colonic does not end after one amount of water is introduced.
At Iowa Colonics, Joanna gradually introduces warm, filtered water through the Aquanet APS-100. You remain on the treatment table.
As water enters, it has time to contact stool inside the colon. Harder, drier stool can absorb water and begin to soften. Gas can shift. Your colon can begin moving.
When your body is ready to release, the water, gas, stool and other released material flow out through enclosed tubing. Then another fill can begin.
- Water flows in.
- Stool has time to absorb water and soften.
- Your body releases.
- Water and released material flow out.
- Another gradual fill begins.
A typical Iowa Colonics session moves through these changing fills and releases for 45 to 60 minutes.
There is no suction pulling poop out of you. Joanna controls the water going in. Your body determines when it releases.
Why Does That Feel Different From an Enema?
Because the first bowel movement does not have to be the end of the process.
With an enema, you may have a bowel movement within minutes. That may be exactly what you wanted.
But some people have had the experience of finally pooping and still thinking, “There is more in there.”
You may feel less pressure but still feel full. You may poop but still feel backed up. You may get some stool out but still have the uncomfortable feeling that you are not finished.
A colonic gives the process substantially more time.
One fill may release stool immediately. Another may mostly move gas. Another may produce very little while harder stool continues absorbing water. A later fill may release stool that was not ready to move earlier in the session.
A colonic gives your body repeated opportunities to fill, soften and release during one extended session.
Is a Colonic Just an Enema With More Water?
No.
The important difference is not simply the amount of water. It is how that water is delivered over time.
Typical Fleet Adult Saline Enema
A current adult Fleet saline enema delivers 118 mL in one finite administration. You retain it briefly and then evacuate.
Iowa Colonics Session
Water enters. Your body releases. That water leaves. More water can enter. Your body releases again. The process can continue throughout a 45-to-60-minute session.
A colonic does not place the entire session’s water inside your colon at once. Water enters and leaves repeatedly.
That means the total amount of water passing through during a long irrigation session can be much greater than the amount present inside the colon at any single moment.
Research Shows How Different Repeated Irrigation Can Be
In a published 2022 medical colon-hydrotherapy study, the irrigation process averaged about 60 minutes, 14.8 filling-and-emptying cycles and about 59 liters of cumulative water during the entire procedure.
That does not mean 59 liters were inside the colon. Water was entering and leaving repeatedly.
It also does not mean an Iowa Colonics APS-100 session uses 59 liters. That research used different equipment.
The reason the study matters here is much simpler: repeated irrigation over an hour is a fundamentally different process from administering one small volume of fluid once.
Does an Enema Only Reach the Rectum?
No.
Iowa Colonics does not oversimplify this comparison just to make colon hydrotherapy sound better.
Enema fluid can travel beyond the rectum.
In one imaging study, researchers tracked a 60 mL medication-retention enema. The fluid reached the sigmoid region in every administration, the region of the splenic flexure in 22 of 24 administrations, and the transverse colon once.
This was a medication-retention enema held for hours, not a fast-acting Fleet cleansing enema. So we do not assume every enema behaves the same way.
The important difference is not a made-up line showing where enema water stops.
The important difference is the process: a typical small-volume cleansing enema gives one finite administration, while colon hydrotherapy repeatedly introduces and releases water over a much longer period.
Does Colonic Water Reach the Entire Colon?
Not necessarily.
Research using imaging has shown that retrograde colon-irrigation fluid can travel far into the colon.
In one study, irrigation fluid reached, on average, just beyond the right colic flexure.
This was not an APS-100 study, so Iowa Colonics does not claim that every APS-100 session reaches that exact location.
Bodies are different. Sessions are different. How far water travels can be different.
Water Reaching Stool and Stool Actually Coming Out Are Two Different Things
Suppose water reaches a particular part of the colon. That tells us water reached that area.
It does not prove every piece of stool in that area came out.
Research examining retrograde colon irrigation has measured both where irrigation water traveled and where stool was actually evacuated. Those were not identical results.
Iowa Colonics does not claim: “If the water reached it, the colon is now completely empty.”
A colonic is not a guarantee of complete emptying. It is a process that gives water time to contact stool while your body moves through repeated fills and releases.
The APS-100 Is Doing More Than Holding a Bag of Water
Iowa Colonics uses the Aquanet APS-100. Joanna operates it throughout your colonic.
Joanna Controls How Quickly the Water Enters
The APS-100 has manual treatment-water flow control. Joanna can slow the incoming water or allow more flow based on how you are feeling and how the session is progressing.
Joanna Can See the Incoming Flow Rate
The APS-100 has a flow meter that displays the rate of treatment water entering the colon.
The System Monitors Pressure
As the colon fills, pressure naturally increases. The APS-100 uses Applied Pressure Sensing Technology to detect rising intracolonic pressure.
The manufacturer states that the system automatically diverts water through an internal bypass to maintain intracolonic pressure below 2 psi.
In plain English: when pressure rises, the equipment is designed to reduce continued incoming pressure rather than blindly keep pushing water in.
The Water Temperature Is Controlled
The APS-100 regulates the incoming municipal water to the selected treatment temperature and includes automatic thermal protection.
The Water Goes Through Three Stages of Treatment
Before treatment water enters the system, it passes through a pre-filter, activated carbon and UV treatment.
You Release Through Enclosed Tubing
At Iowa Colonics, the APS-100 is used in a closed setup. When your body releases, water, poop, gas and other released material travel through enclosed tubing while you remain on the treatment table.
There Is No Suction Pulling Stool Out of You
The APS-100 is not vacuuming stool out of your colon.
Water enters. Your colon responds. Pressure rises naturally. The system regulates incoming flow. Then your body releases.
The process works with evacuation, not by mechanically vacuuming the bowel empty.
So Which Is Better: a Colonic or an Enema?
That depends on what you are trying to do.
If you want a quick, inexpensive intervention that may trigger a bowel movement within minutes, an OTC enema may be all you need.
A colonic is different.
It takes longer. It is practitioner-guided. It involves specialized equipment. And it uses repeated irrigation and release rather than one administration.
That difference may matter if your frustration is not simply: “I have not pooped today.”
It is: “I poop, but I still feel backed up.” “Some came out, but I still feel full.” “I feel heavy and uncomfortable.” “I keep going to the bathroom without ever feeling finished.”
What a Colonic Cannot Guarantee
Iowa Colonics does not promise that:
- Every colonic reaches the entire colon.
- Every piece of stool comes out.
- A particular number of bowel movements will happen.
- A specific amount of stool will be released.
- One session will make you completely empty.
- A colonic is medically superior to an enema for every person.
Your body determines what it is ready to release. That is also why one person’s session can look very different from another person’s session.
What You Get at Iowa Colonics
Every Iowa Colonics appointment is private and one-on-one. Joanna Ayala personally performs every colonic.
- A private treatment room.
- A private bathroom and changing area.
- The Aquanet APS-100.
- A new, unopened, single-use client kit.
- Warm, filtered treatment water.
- Practitioner-controlled water flow.
- Pressure and temperature management.
- A contained closed-system release.
- 45 to 60 minutes for the actual colonic.
You remain in communication with Joanna throughout the session. If you want the water slowed, paused or stopped, tell her. If you want to stop completely, the session stops.
If You Tried an Enema and Still Feel Like There Is More
Now you know why a colonic is not simply the same thing with a different amount of water.
An enema can create a quick bowel movement.
A colonic gives your body a longer process: fill, soften, release, repeat.
If you are tired of pooping a little and still walking away feeling backed up, you can experience one complete colonic and decide from your own body what the difference feels like.
Colonics begin at $130.
Important Safety Information
Colon hydrotherapy is a non-medical wellness service and is not appropriate for everyone.
Severe or persistent abdominal pain, repeated vomiting, major abdominal swelling, significant rectal bleeding, fainting, severe weakness, concerning inability to pass gas, or possible bowel obstruction or perforation require appropriate medical evaluation.
Do not delay needed medical care to receive colon hydrotherapy.
Iowa Colonics screens clients for contraindications before treatment.
