Doctors Caution Colon Cleansers May Clean Body of Nutrients

BETHESDA, Md. (NNS) -- Doctors at the National Naval Medical Center (NNMC) encouraged Sailors to avoid using unhealthy measures, like colon cleansers, to meet physical standards Aug. 11.

While the manufacturers of these cleansers claim they help shed pounds and free the body of toxins, Capt. Brooks Cash, Chief of Medicine for NNMC and Walter Reed Army Medical Center (WRAMC) said these could potentially lead to severe health hazards.

"There is a belief that stool in your colon clogs like a pipe and occasionally needs cleaning out. That is a myth," said Cash.

Additionally, there is no evidence of improved health with colon cleansing and over-the-counter medicinal laxatives and enemas used to perform these "cleansings," said Cash, who is also Professor of Medicine at the Uniformed Services University of the Health Sciences. He added that such rituals can lead to dehydration and potentially deadly electrolyte abnormalities.

In reality, the food we eat is not stored for long periods within the body. It is broken down into one- to two-millimeter particles of basic sugars, fats and proteins in the stomach. It is then absorbed by the small intestine where it is used to nourish the body. The unusable particles are sent to the colon where water is reabsorbed to form solid stool. This waste is then expelled from the body, Cash explained.

"Humans have been around for a pretty long time," he added. "There is no reason to use colon cleansers when your body has adapted to do such a good job of that on its own."

Touting such benefits as weight loss, shinier hair and greater overall health with the removal of "toxins" that build up in consumers' digestive tract, colon cleansers come in the form of pills, powders to be mixed with liquid and enemas; however, reading the fine print on the labels of these "ultimate colon cleansers" reveals such common side effects as nausea, vomiting, intestinal cramping, drowsiness and fatigue.

"There are numerous reports that these cleansers, especially the high colonics, have caused direct harm to patient's bodies, such as infections, colonic perforation, and even death," said Lt. Cmdr. Ruben Acosta, staff gastroenterologist and Assistant Professor of Medicine at USU. "These types of injuries and infections are especially prevalent because the cleanse is performed by alternative practitioners who are not subject to the same safety or hygiene regulations that protect the patients who undergo standard medical procedures."

Cash added that colon cleanser manufacturers take advantage of people by capitalizing on their fears of being overweight, unattractive or unhealthy. To combat those issues and sustain health, he recommends patients eat fiber, maintain an ideal body weight, exercise, not smoke and use alcohol only moderately, if at all.

"Another critically important preventative measure to take is to begin colon cancer screening at the appropriate ages," said Cash.

According to Cash, the only common reason other than problematic, severe constipation to do a colon cleanse is in preparation for a colonoscopy or virtual colonoscopy, two of the colon cancer screening options offered by the Gastroenterology Service at NNMC.

Patients with no family history of colon cancer should begin screening at age 50, regardless of gender; African-Americans should start at age 45. Anyone with at least two grandparents or one parent or sibling who suffered from colon cancer should begin screening at age 40 or 10 years before the age the relative was diagnosed.

"Colon cancer is the third most common cause of cancer and the second most common cause of cancer death in the US; however, it is largely preventable." said Cash. "Screening needs to occur every five to ten years, regardless of symptoms, as colon cancer is often silent until too late."
