Butt Breathing Could Be a Life Saver for People With Lung Disease

In a discovery straight out of science fiction, researchers have found that mammals—including humans—might absorb oxygen through their intestines. Dubbed “butt breathing,” this surprising method could offer a lifeline for patients with severe respiratory conditions.

A study in Med reveals that oxygen-deprived mice and pigs survived longer when given oxygen rectally. This breakthrough could transform emergency medicine, especially for COVID-19, COPD, and pneumonia patients.

How Does Butt Breathing Work?

While it sounds bizarre, intestinal oxygen absorption isn’t unheard of in nature. Sea cucumbers and some fish use their guts to breathe in low-oxygen water. But could mammals do the same?

Researchers tested two methods on animals:
1. Gas Ventilation – Pumping pure oxygen into the rectum.
2. Liquid Oxygen Enemas – Administering perfluorocarbon (PFD), an oxygen-rich fluid.

The results stunned scientists: mice survived extreme oxygen deprivation, and pigs showed improved blood oxygen levels—without major side effects.

Why Butt Breathing Matters for Humans

For patients with failing lungs, ventilators and ECMO machines are often the only options. But these treatments are invasive and scarce in emergencies.

Enter enteral ventilation via anus (EVA)—a simpler, less invasive alternative. Dr. Takanori Takebe, a lead researcher, explains: “The rectum’s dense blood vessels make it ideal for rapid oxygen absorption.”

Potential Applications:

• Emergency oxygen for drowning victims
• Rescue aid for miners or trapped individuals
• Backup treatment for COVID-19 lung failure

Challenges and Ethical Concerns

Despite its promise, EVA faces hurdles:
– Safety: Could oxygen enemas harm gut bacteria?
– Social Stigma: Will patients accept “butt breathing”?

Researchers remain hopeful, refining methods for human trials. Future studies will examine long-term effects and neonatal uses for premature babies.

The Future of Unconventional Medicine

Butt breathing might sound absurd, but it underscores how innovation can emerge from unexpected places. As science pushes boundaries, could this be the next big medical breakthrough?
