The Science Behind Gut Cleanses: Helpful or Harmful?
A “gut cleanse” involves flushing out your colon (your large intestine) with a lot of a water-based fluid. Some people call this process a “colon cleanse,” “colonic irrigation,” or “colonic hydrotherapy.” It’s based on the ancient theory of autointoxication, believing in the need to rid your gut of built-up toxins to prevent ill health.
What does the science say about gut cleanses?
A colon cleanse involves using a lot of warm, water-based fluid — often up to 60 liters — to flush out your large intestine. It takes about 45 minutes and involves inserting a tube into your rectum.
The science behind a gut cleanse
In some scenarios, gut cleansing may be helpful. For example, a study found that participants with chronic constipation or fecal incontinence who had gut cleanses for 12 months reported an improvement in gut function and quality of life. However, it’s essential to note that gut cleanses aren’t beneficial for everyone.
Other studies show that gut cleanses can improve symptoms of chronic constipation and other bowel disorders. For individuals with irritable bowel syndrome (IBS), there’s evidence that a gut cleanse can enhance constipation, pain, and diarrhea.
A gut cleanse can provide relief from gastrointestinal symptoms for some people for short periods, but it doesn’t address the underlying cause of the issues.
The dangers of gut cleanses
Aside from specific scenarios, there’s no evidence that gut cleanses and detoxes offer health benefits and they come with risks.
Unwanted gut symptoms
Gut cleanses can cause mild gut symptoms like bloating, pain, and diarrhea, and may lead to soreness or sensitivity around the rectum. They have also been linked to side effects such as vomiting, dehydration, and electrolyte imbalance.
Perforation
A gut cleanse can result in a perforation of the large intestine, which requires immediate medical attention.
Gut microbiome disruption
A gut cleanse disrupts the balance of the gut microbiome, removing beneficial bacteria crucial for gut health. This disruption can exacerbate digestive problems in the long term.
Infection
Gut cleanses are invasive procedures that could introduce harmful bacteria into the large intestine, potentially leading to infections.
Alternatives to gut cleanses
While gut cleanses may benefit individuals with specific gut disorders, it’s vital to consider the risks. Consulting a healthcare professional for symptom management is recommended. Dr. Bulsiewicz suggests fiber as a key component for better gut health.
There are numerous ways to support gut health without resorting to cleanses, including drinking plenty of fluids, focusing on a balanced diet, getting adequate sleep, avoiding smoking and excessive alcohol consumption, and trying probiotic fermented foods.
Key takeaways about gut cleanses
Gut cleanses involve using water-based fluid to flush out the large intestine. While beneficial for some individuals with specific conditions, they pose risks and may not offer overall health benefits.
Supporting gut health through a balanced diet rich in fiber and other nutrients, adequate hydration, and healthy lifestyle choices is crucial for long-term well-being.
