Imagine a future in which your health practitioner could predict how close to dying you are just by examining your poop? While it may not exactly be the first thing you would even consider imagining, there is a reason I am proposing this scenario to you. As it turns out, a new study has indicated that this may soon be a reality. According to the researchers, your poop’s chemical makeup, particularly the gut-bacteria-produced metabolites, may help in predicting death risk in the critically ill. By analyzing these fecal metabolites, doctors are able to work out your Metabolic Dysbiosis Score (MDS).
This score determines if you have gut dysbiosis, a gut microbiota imbalance associated with several health issues. By studying the substance found in feces, the researchers were able to identify certain patterns that indicated whether an individual in the ICU would survive the following 30 days. Although it is an unconventional technique, it could potentially revolutionize the manner in which doctors monitor the critically ill. Let’s find out more about how your microbiome may just be a vital yet untapped health indicator.
For the study, researchers from the Amsterdam University Medical Centers and the University of Chicago examined 196 ICU patients diagnosed with severe conditions such as septic shock and respiratory failure. All of these patients were at risk of dying within a short period. The researchers collected stool samples from the patients and analyzed them for chemical compounds called metabolites. These tiny compounds are the byproducts produced when bacteria in the gut digest food and interact with the body.
While hundreds of these metabolites were measured, the researchers focused on 13 that appeared to play a vital role in distinguishing the patients who survived from those who did not. These specific metabolites are connected to important biological functions such as immune response, the regulation of inflammation, and gut barrier health. The researchers then created the Metabolic Dysbiosis Score (MDS) system using this information. The team noted that the higher the MDS score, the more out of balance the patient’s gut was.

Furthermore, the more out of balance their gut was, the greater the likelihood of their dying within the next month. The results of the study were rather shocking. In the initial group, the MDS was able to predict who would die within 30 days with 84% accuracy. They were even more surprised to learn that conventional indicators, such as gut bacteria diversity, vital signs, and age, weren’t nearly as accurate. As it turns out, it was the chemicals that the microbiome produced that mattered the most. This indicated that even when the microbial system seems somewhat stable, a deeper microbial function imbalance could quietly be wreaking havoc.
Why Your Microbiome Is More Important than You Thought
Your gut microbiome consists of trillions of bacteria and microbes that live in your intestines. For many years, the scientific community has known that it plays a crucial role in your health. It helps produce vitamins, digest food, and even helps regulate mood via the gut-brain axis. This new research, however, indicates that it is actually the metabolic activity of the microbiome that can best act as an indicator of your body’s health.
Many of the 13 metabolites identified are related to compounds like short-chain fatty acids, bile acids, and tryptophan derivatives. These help support gut lining, regulate metabolism, and immune response. When these compounds are out of balance, it could affect your body’s ability to regulate inflammation or combat infections. Therefore, a bad MDS score isn’t just reflecting your gut, but your overall system. These imbalances typically occur before any outward symptoms appear. This means that MDS could provide an early warning for those who seem okay on the outside, yet are rapidly declining internally.
This could help doctors in the ICU determine who needs immediate intervention and who could potentially recover with normal care. Additionally, there’s also potential for the MDS score to help change health outcomes, and not only predict them. If health practitioners know exactly which metabolites are imbalanced, they could potentially develop targeted therapies for the patient. This could include personalized probiotics, diet changes, or even direct supplementation.
The Bottom Line
The idea that your poop could reveal if you are about to die may seem a little strange or even gross. Yet, your feces actually imparts information about your body that even advanced technologies are unable to. The Metabolic Dysbiosis Score is perhaps just the beginning of a medical revolution. A shift in view that views the gut not just as a digestive system, but as a vital indicator of your body’s internal state. This could potentially lead to personalized treatments and life-saving interventions in the near future.
