Why have a colon hydrology test?

Constipation, bloating, a feeling of a swollen stomach, irregular bowel movements, or the sensation of incomplete evacuation… These digestive issues can have a significant impact on daily comfort and quality of life. The colon plays an essential role in digestion. These digestive issues can arise, in particular, when the colon’s function is disrupted.

The colon, also known as the large intestine, is the final part of the digestive system and is approximately 1.5 meters long (or longer in cases of dolichocolon). It performs several essential functions: it reabsorbs some of the water and minerals contained in food residues, helps form stool, and ensures its elimination. It also houses the gut microbiota, a community of billions of microorganisms that contributes to proper digestion and the body’s overall balance.

Its function can be affected by many factors, such as a low-fiber diet, inadequate hydration, a sedentary lifestyle, chronic stress, certain medications, hormonal changes, or certain digestive disorders. When bowel transit slows down, stool remains in the colon longer. It gradually becomes dehydrated, harder to pass, and can promote the fermentation of food residues. This fermentation can lead to digestive problems.

When these symptoms become persistent or recurrent, personalized care may be considered. Colon hydrology is one of the complementary approaches that can be offered to support the colon’s natural elimination functions and promote better digestive comfort. It is part of a comprehensive care plan tailored to your situation and needs.

Colonic hydration may also be recommended as part of preparation for a colonoscopy.

What is colon hydrology, colonic irrigation, or colon hydrotherapy?

Colonic hydrotherapy (also known as colonic irrigation or colon hydrotherapy) is a gentle technique that involves cleansing the large intestine using warm, filtered water. Performed by a trained therapist, it supports the colon’s natural elimination functions.

Unlike an enema, which acts primarily on the rectum and the lower part of the colon, colon hydrotherapy provides a more thorough cleansing of the large intestine through the gradual introduction of water in a closed system that ensures hygiene, comfort, and privacy.

This technique now benefits from modern equipment that allows sessions to be conducted under optimal conditions of safety and comfort.

What effects can you expect from a colonic irrigation session?

Colonic hydrotherapy can help support the body’s natural elimination processes. The effects experienced vary from person to person, but many patients report improved digestive comfort and a pleasant feeling of lightness after a session.

Promote a healthier digestive balance

Colonic irrigation can help support the body’s natural bowel function and promote smoother bowel movements. For some people, it also leads to improved digestive comfort, with a reduction in feelings of heaviness and bloating.

May help with:

✓ Promote more regular bowel movements

✓ Improve digestive comfort

✓ Reduce feelings of bloating, heaviness, and abdominal tension

hydrologie 3

Rediscover a sense of lightness and freedom

After a session, many patients describe a pleasant sensation of lightness and relief in the abdomen. This feeling of well-being is one of the most commonly reported effects, although each person’s experience is unique.

Patients often report:

✓ A lighter feeling in the stomach

✓ A sense of freedom

✓ An immediate sense of well-being

hydrologie 1

In some cases: preparation for a colonoscopy (or coloscopy)

Colonic irrigation may sometimes be performed as part of a specific preparation for a colonoscopy, when recommended by a healthcare professional. A thoroughly cleansed colon can improve visibility of the mucosa during the exam.

Colonic hydrology is part of a complementary approach

Colon hydration therapy is not a substitute for a medical consultation. If you experience severe pain, blood in your stool, unexplained weight loss, recent or persistent constipation, or any other unusual symptoms, it is important to see your doctor or a gastroenterologist to determine the cause.

How does a colon hydrology session work?

The patient lies comfortably on his or her back.
A sterile , single-use cannula is inserted into the patient’s rectum. The practitioner then performs successive “enemas” of 0.5 to 3 liters, at a stable, preset temperature and flow rate.

Through abdominal massage, the practitioner promotes abdominal relaxation.

The procedure takes about 45 minutes. Depending on the treatment goals, the therapist may recommend certain supplemental products (probiotics, magnesium, chlorophyll, etc.). These options are never routine; they are chosen based on your health status, your needs, and the absence of any contraindications.

How many sessions are generally recommended?

The number of sessions is determined in consultation with your therapist, based on your needs, your health status, your medical history, and your goals. The first session serves both to conduct a personalized assessment and to observe your response to the treatment. At the end of the session, your therapist will work with you to determine the number of sessions and their frequency, in order to provide you with care tailored to your situation.

In most cases, our therapists often recommend 2 to 3 sessions scheduled relatively close together to gradually support the functioning of the digestive system and promote better intestinal comfort.

Subsequently, follow-up sessions may be scheduled depending on how your needs evolve, in order to maintain the benefits you’ve achieved and tailor the follow-up to your pace.

In certain specific situations, the frequency of sessions may be adjusted in consultation with your doctor, particularly when they are part of a comprehensive medical treatment plan.

Some people also choose to have another session when they experience a recurrence of digestive discomfort, such as bloating, a feeling of heaviness, or irregular bowel movements.

Preparing for a session: Our recommendations:

In the two days leading up to the appointment, we recommend eating light meals in particular:

  • by cutting back on animal protein, dairy products, and gluten (bread, wheat, cookies, pastries),
  • by eliminating raw vegetables and raw fruit for people who experience bloating,
  • by eating wholegrain cereals and cooked vegetables and fruit.

We will send you a preparation protocol with your appointment confirmation e-mail.

Are there any contraindications to colon hydrotherapy?

Colonic hydrotherapy is not suitable for all medical conditions. During your first consultation, your therapist will take the time to review any potential contraindications with you and ensure that this treatment is appropriate for your situation.

Colonic irrigation is contraindicated in the following cases:

  • visceral or gynecological surgery performed within the last 3 months;
  • colon cancer;
  • anal fissure;
  • pregnancy.

In cases of diverticulitis, a hemorrhoidal flare-up, or chronic inflammatory bowel disease (IBD) in the acute phase, colon hydrotherapy is generally not recommended and should be postponed until the condition improves.

If you have any questions, please don't hesitate to contact us. We'll be happy to provide you with information and, if necessary, refer you to your doctor.

Could colon hydrology be helpful in my situation?

Here are a few conditions for which colon hydrology may be recommended. This list is not exhaustive and links to dedicated information pages explaining our approach for each situation.

Why should you have your colon hydrotherapy done at La Clinique Naturelle?

Two experienced professionals with complementary backgrounds.

Colon hydrotherapy is provided by Marie-Anne Geiser, a naturopath, and Nathalie Favre-Coutillet, a nurse. Their complementary skills, combined with more than 20 and 15 years of experience, respectively, ensure care that is thorough, personalized, and focused on your needs.

Both have received specialized training in this technique and are ASCA-certified.

A safe environment and strict hygiene standards

Colonic irrigation is performed in a dedicated room using equipment specifically designed for this procedure. Each session is conducted in accordance with strict hygiene protocols, using a closed-loop system and single-use cannulas, to ensure your safety, comfort, and privacy.

A multidisciplinary team at your service

Marie-Anne Geiser and Nathalie Favre-Coutillet work as part of a team of therapists with complementary skills. Regular discussions among professionals, the sharing of experiences, and knowledge of different approaches help enrich each treatment plan.

When appropriate, they can also refer you to other therapies offered at the Clinique Naturelle—such as nutrition, chi nei tsang, naturopathy, acupuncture, or other complementary treatments—to best meet your needs.

A complementary approach to conventional medicine

Colonic hydrology is part of a complementary approach to conventional medicine. It is never a substitute for medical care and can, when necessary, be integrated into a coordinated treatment plan with your doctor or other healthcare professionals.

Are the sessions covered by supplemental insurance?

Some supplemental insurance plans may cover part of the cost of these sessions. Since reimbursement terms vary from one insurer to another, we recommend that you check directly with your insurance provider before your first appointment.

To obtain accurate information, it is recommended that you provide the therapist’s name and the type of therapy involved, as these two factors are generally taken into account when determining reimbursement.

What our patients say

Two years ago, I had a severe skin condition. Parts of my body were completely inflamed; it felt like shards of glass were scraping my skin. That was just the tip of the iceberg: the good bacteria in my gut flora were completely depleted, and I had to start from scratch.

Two years later, the problem has been resolved—or rather, it’s under control thanks to a treatment that’s working. This addiction isn’t without its consequences; I have to regularly monitor my overall health because such aggressive treatment inevitably affects the body’s overall balance (white blood cells, liver, lungs). I had the idea of trying colon hydrotherapy to start fresh and build a solid foundation for good health going forward. Taking care of your insides—clearing them of accumulated waste and giving them a deep cleanse—is, in a way, like looking after your life partner!Following the recommendations of the professionals Marie-Anne and Nathalie, I had two sessions in quick succession, then a final one two months later. It was to the most recent session that I reacted the fastest, as if this reactivated body had begun to show itself the moment I decided to take care of it.
It’s not easy to consider taking this step. Aside from *The Imaginary Invalid*, who makes us laugh with his obsession with enemas, we don’t readily focus on our stools. We’re not ready to tackle the problem at its root—that is, why our digestive system is causing us trouble, and what it’s trying to tell us through its signs of distress. When our insides go haywire, it means something is truly wrong!
In fact, when we go to the Clinique Naturelle for a session, we’re heading to our colon’s beauty salon. Everything is beautiful, bright, feminine, and cozy—and surprisingly, everything smells wonderful. Nothing reminds us of an enema—and that’s a good thing. What’s more—and this is essential—Marie-Anne and Nathalie have magic fingers; they massage us as our bellies fill with warm water, helping our intestines relax, release, and rejuvenate. Their extensive medical experience puts us at ease, and their humanity and kindness envelop us like a cocoon…

"What a discovery!
This treatment will now be part of my routine for maintaining my health. With my 60th birthday just around the corner, better late than never!"

Faced with the saturation of work, responsibilities, stress, overconsumption of food, dʹalcohol and medication, and pollution, some people decide to treat themselves by "emptying the belly". At the Clinique naturelle in Geneva, Marie-Anne Geiser offers her patients colon hydrology, a kind of thorough enema. These therapies are fashionable, but are they recent? Behind the idea of a bodily emptying, isnʹt there the dream of a psychological and symbolic cleansing? Sociologist Francesco Panese, professor of social studies of science and medicine at the University of Lausanne, has long been interested in these practices.
