How do you flush out your colon?


A colon cleanse, also called colon hydrotherapy or a colonic, is a procedure that claims to remove waste and toxins from the colon. Some people use colon cleanses to detoxify the body, improve health, or promote weight loss. However, there is no scientific evidence that colon cleanses are beneficial. In fact, they can sometimes be harmful. This article will provide an overview of colon cleanses, their claimed benefits and risks, and some healthier alternatives for supporting digestive health.

What is a Colon Cleanse?

A colon cleanse involves flushing out the contents of the large intestine, also known as the colon. There are different methods used:

Method Description
Colon hydrotherapy Uses filtered water to gently flush the colon through a tube inserted into the rectum. Typically performed at a spa, clinic or doctor’s office.
Enemas Involve flushing water, sometimes mixed with herbs, acids or coffee, into the rectum to induce bowel movements.
Laxatives Stimulate bowel movements through chemical means. Can be taken orally or rectally.
Supplements Often contain herbs, fibers or chemicals that claim to loosen stool and cleanse the colon.

The premise behind colon cleanses is that toxic waste and mucus accumulate in the colon over time. Removing this waste is said to reduce inflammation, boost immunity, improve digestion and enhance overall wellbeing. However, there is no scientific evidence to support these claims.

Purported Benefits of Colon Cleanses

Advocates claim that colon cleanses provide the following benefits:

  • Remove toxins, waste and bacteria from the colon
  • Boost energy and alleviate fatigue
  • Treat constipation and promote regular bowel movements
  • Improve digestion and absorption of nutrients
  • Enhance immune function
  • Relieve inflammation in the gastrointestinal tract
  • Aid in weight loss
  • Reduce risk of colon cancer
  • Clear skin conditions like acne
  • Eliminate parasites or candida overgrowth

However, there is no credible evidence that colon cleanses can provide these effects. The colon already effectively eliminates waste material and bacteria. Some of the claims, like aiding weight loss and clearing acne, rely on the disproven theory of auto-intoxication. This is the belief that toxins enter the bloodstream through the colon, causing system-wide effects. However, studies show the colon does not absorb enough toxins to impact other organs. Overall, colon cleanses are not necessary for good health.

Potential Risks of Colon Cleanses

Colon cleanses come with the following possible side effects and risks:

  • Dehydration from fluid shifts
  • Electrolyte imbalances
  • Infection from improperly sanitized equipment
  • Perforations or punctures in the colon
  • Damage to intestinal flora
  • Abdominal pain and cramping
  • Nausea, vomiting, dizziness
  • Electrolyte abnormalities
  • Allergic reactions

There have also been some reported cases of more serious complications from colonics like severe dehydration, bowel perforations, sepsis, renal failure and electrolyte imbalances.

Repeated use of colon cleanses may make the bowels dependent on laxatives to properly function. Some herbal colon cleansers contain ingredients like senna, rhubarb root and cascara that can permanently damage the colon muscles over time.

Colonics should be avoided in people with gastrointestinal conditions like Crohn’s disease, ulcerative colitis, diverticulitis, severe hemorrhoids, colon cancer or recent rectal surgery. Those with kidney disease, heart conditions or electrolyte abnormalities should also steer clear. Pregnant women should not undergo colonics due to infection risks.

Overall, colon cleanses come with considerable health risks and are not recommended by doctors or dietitians. There are safer and more effective methods for improving gut health and relieving occasional constipation.

Healthier Alternatives to Colon Cleanses

Instead of doing risky colon cleanses, try these natural, gentle ways to support your digestive health:

  • Eat More Fiber: Aim for 25-35 grams of fiber per day from vegetables, fruits, whole grains, beans, nuts and seeds. Fiber promotes healthy bowel movements.
  • Stay Hydrated: Drink water and unsweetened fluids throughout the day. Proper hydration keeps the colon functioning optimally.
  • Exercise Regularly: Moderate activity like brisk walking for 30 minutes daily helps prevent constipation.
  • Manage Stress: Uncontrolled stress can disrupt your gut microbiome and digestive function. Try relaxation techniques.
  • Take Probiotics: These healthy bacteria support digestive health and immunity.
  • Eat Prebiotic Foods: Sources like garlic, onion, banana and asparagus feed probiotics in your colon.
  • Limit Alcohol and Smoking: These irritate the gastrointestinal tract and worsen constipation.
  • Talk to Your Doctor: Get an evaluation if you have persistent bloating, abdominal pain, diarrhea or constipation.

Making healthy lifestyle choices is the safest way to keep your colon working efficiently. Always talk to your doctor before attempting colon cleanses or other unproven detoxification methods.

When Constipation May Indicate a Health Problem

Occasional constipation is very common and usually responds well to simple home remedies. However, if you experience any of the following symptoms, see your doctor to rule out an underlying disorder:

  • Persistent or worsening constipation over several weeks or longer
  • Rectal bleeding or blood in the stool
  • Unintentional weight loss
  • Severe or progressively worsening abdominal pain
  • Nausea and vomiting
  • Persistent diarrhea alternating with constipation
  • Weakness, fatigue or dizziness
  • Swollen abdomen or abdominal masses

These types of symptoms may be linked to health conditions like:

  • Bowel obstruction from scar tissue, tumors or colon cancer
  • Gastrointestinal disorders like irritable bowel syndrome or inflammatory bowel disease
  • Anal fissures or rectal prolapse
  • Neurological disorders like multiple sclerosis, Parkinson’s or spinal injuries
  • Metabolic conditions like diabetes or hypothyroidism
  • Eating disorders
  • Side effects of medications

Early evaluation and treatment of these underlying issues can prevent complications. Your doctor can run tests to determine if there’s a cause other than everyday constipation. Don’t try to self-treat worsening or severe long-term constipation without seeking medical advice.

When to Seek Emergency Care

Most cases of constipation are not emergencies. However, seek immediate medical care if you experience:

  • Intense or worsening abdominal pain and swelling
  • High fever over 101°F (38°C)
  • Blood in vomit or bile-stained vomit
  • Chest pain or rapid heart rate
  • Marked vomiting or dehydration
  • Changes in mental status like confusion or delirium

These symptoms can indicate a bowel obstruction, intestinal tear (perforation), ischemic colitis, volvulus, or other serious condition requiring hospitalization. Don’t hesitate to go to the emergency room or call 911 if you have severe, alarming symptoms related to constipation.


Colon cleanses are unnecessary procedures that come with considerable risks and no proven benefits. Simple diet and lifestyle measures can relieve occasional constipation safely. Seek medical advice if you experience severe, worsening or persistent digestive symptoms. Your doctor can properly evaluate and treat any underlying conditions to get your bowel habits back to normal. With the right prevention and treatment guidance, you can keep your colon healthy for life.
