Natural Colon Cleansing: Is It Necessary?
The practice of natural colon
cleansing dates back to ancient Greece. In the U.S., cleansing the colon
-- the large intestine -- became popular in the 1920s and 1930s. But when the
theories behind it lost support, it fell out of favor. Recently, though, colon
cleansing -- using, for example, teas, enzymes, or colon irrigation -- has
experienced resurgence.
Is colon cleansing good
for you? The jury is still out. That is because researchers have devoted little
study to colon cleansing. For now, here is some information that might help you
decide whether colon cleansing is for you.
What is natural colon cleansing?
There are two main colon-cleansing methods. One involves buying
products; the other involves seeing a practitioner to have a colon irrigation.
Colon cleansing with powdered or liquid supplements.
You take some supplements
used for colon cleansing by mouth. Others
you take through the rectum. Either way, the idea is to help the colon to expel
its contents. You can find these products on the Internet or in health food
stores, supermarkets, or pharmacies. They include:
Colon cleansing with colon irrigation (high colonics). The
first modern colonic machine was invented about 100 years ago. Today, colonic
hygienists or colon hydrotherapists perform colon irrigations. Colon
irrigations work somewhat like an enema. But they involve much more water and
none of the odors or discomfort. While you lie on a table, a low-pressure pump
or a gravity-based reservoir flushes several gallons of water through a small
tube inserted into your rectum.
After the water is in the colon, the therapist may massage
your abdomen.
Then you release the water like a regular bowel movement;
the process flushes out the fluids and waste. The therapist may repeat the
process, and a session may last up to an hour.
The practitioner may use a variety of water pressures and
temperatures and may or may not combine water with enzymes, herbs, coffee, or probiotics.
Probiotics
are supplements
containing beneficial bacteria.
What is the theory behind natural colon cleansing?
One of the main theories behind colon cleansing is an ancient
belief called the theory of autointoxication. This is the belief that
undigested meat and other foods cause mucus buildup in the colon. This buildup
produces toxins, the theory goes, which enter the blood's circulation,
poisoning the body.
What is the theory behind natural colon cleansing? continued...
Some people claim these toxins cause a wide range of symptoms,
such as:
On the surface, the idea of toxins being reabsorbed by the body
makes some sense. After all, rectal suppositories are used to rapidly
administer drugs. Could toxins, too, be quickly entering the bloodstream from
the colon?
If colon cleansing has any effect, however, it likely has less to
do with toxins than with its impact on the nervous system. What's the
evidence? Reflexes in the bowel affect the entire nervous system. In fact, a
wide range of symptoms caused by constipation
can be relieved by enemas. If this is true of enemas, then perhaps colon
cleansing has a similar effect.
What is the goal of natural colon cleansing?
The health claims made by producers of colon cleansing products
and colon irrigation practitioners are broad and wide-reaching. Their main goal
is to clear the colon of large quantities of stagnant, supposedly toxic waste
encrusted on colon walls. Doing so, they claim, will enhance the vitality of
the body.
Other stated goals include:
- Improving mental outlook
- Improving the immune system
- Losing weight
- Reducing the risk of colon cancer
Colon cleansing has been studied in relation to a few health
concerns. These include:
- Fecal incontinence or bowel leakage
- Ostomy (surgical connection between an intestine and the outside of the body) care
- Spasm during colonoscopy
- Drug withdrawal
- Before and during bowel surgeries
In most of these cases, no quality research has been done to tell
whether or not a colon cleansing is helpful.
Is natural colon cleansing needed?
Are bowel movements
enough to clear the colon? Or is it true that colon cleansing can be
beneficial? This is still unclear. We do know that the body alone can do the
following:
- Natural bacteria in the colon can detoxify food wastes.
- The liver also neutralizes toxins.
- Mucus membranes in the colon can keep unwanted substances from reentering the blood and tissues.
- The colon sheds old cells about every 3 days, preventing a buildup of harmful material.
- The normal number of bowel movements varies from person to person.
- Increasing the number of bowel movements doesn't improve weight loss. That's because the body absorbs most calories before they reach the large intestine.
Are there risks associated with natural colon cleansing?
Remember that "natural" doesn't necessarily mean safe.
The government doesn't regulate natural colon cleansing products, so their
potency, safety, and purity can't be guaranteed. And, each state has its own
rules about whether or not practitioners must be professionally licensed.
If you do decide to see a colon-cleansing therapist, choose one
who is licensed by a recognized national organization and who follows that
organization's standards. It's always a good idea to talk with your primary
health provider before starting a new practice such as colon cleansing.
Although the risk becomes greater the more often you have a colon
cleanse, a review of similar procedures, such as enemas and sigmoidoscopies,
shows the risk of severe effects is low when colon irrigations are performed by
trained personnel using low pressures with the right equipment. In Britain,
where practitioners carry out 5,600 colon irrigations each month, no serious
side effects have been reported.
However, there are some potential side effects:
- Vomiting, nausea, cramps
- Dizziness, a sign of dehydration
- Mineral imbalance
- Potential interference with medication absorption on day of procedure
- Bowel perforation
- Infection
- Depletion of helpful normal bowel flora unless replaced (i.e. probiotics)
Be aware, if the therapist adds a substance to the water
during colon irrigation, you run the risk of an allergic
reaction. Do not use laxatives or colon irrigations long term. They can irritate
or upset the balance of your colon's good bacteria and interfere with normal
bowel function.
Avoid colon irrigations, if you have:
- Diverticulitis
- Ulcerative colitis
- Crohn's disease
- Severe hemorrhoids
- Tumors in your rectum or colon
- Recent bowel surgery
- Heart disease or kidney disease, unless approved by your health care provider
Regarding children, there may be an increase risk of mineral
imbalances, therefore use caution with children. Follow the guidelines of the
IACHC (International Association of Colon Hydrotherapists www.i-act.org) and your health
care provider.
What else can you do to enhance colon health?
What you eat -- not what you flush through your colon -- may have
the greatest impact on colon health, lowering your risk of colon cancer
and enhancing your overall health.
Increasing both soluble and insoluble fiber can help with a wide
range of gastrointestinal problems, including constipation,
diverticular disease, and colorectal
cancer. The typical American consumes 10 grams to 15 grams a day, but you
need closer to 20 grams to 35 grams. If there are no gluten issues, add sources
of both insoluble fiber, such as cereal and whole grains, and soluble fiber,
such as bran, fruit, vegetables, and oatmeal.
Also, drink plenty of fluids, but drink alcohol in moderation.
Avoid tobacco
and limit red meat. And, of course, get screened for colon cancer beginning at
age 50, or earlier if your doctor advises.
