A recent research study has revealed potential health dangers for astronauts embarking on space missions.
The findings show that space travel presents serious risks, not only from the challenges of zero gravity and prolonged weightlessness but also from the negative effects on gut health.
The study identified a significant increase in ‘leaky gut’ syndrome during space missions, where the intestinal lining becomes more permeable, possibly allowing harmful substances to enter the bloodstream.
Published in the Journal of Life Science in Space Biology, the study was conducted by a Nigerian microbiology researcher named Akinsuyi Oluwamayowa.
The research highlights the concerning health risks faced by astronauts in the unique space setting, where traditional medical assistance from Earth is not readily available.
The study demonstrated that a compromised intestinal barrier could lead to toxins and bacteria entering the bloodstream, potentially leading to inflammation and a higher risk of infections.
The report also noted a decrease in the expression of genes crucial for protecting the gut lining, which could have serious implications for an astronaut’s immune system and disease prevention ability.
“In tandem, there was an observed increase in the expression of genes associated with inflammatory cytokines, which are indicative of the body’s response to stress or injury. This increase suggests that space travel triggers inflammatory processes, which could have a range of negative health outcomes. ”
During the study discussion, Oluwamuyiwa pointed out that there were notable changes in the makeup of the astronauts’ gut bacteria.
“The altered gut microbiota and increased gut permeability observed in astronauts could lead to severe health issues that not only affect the individuals but could also jeopardize entire missions,” he noted.
In addition , he uncovered a decrease in important beneficial bacteria crucial for immune system health.
Speaking further,on the research Oluwamayowa stated, “There was a decline in the presence of beneficial bacteria, which are crucial for not only digestion but also for the overall immune system function. Conversely, there was a rise in potentially harmful Gram-negative bacteria. These changes in gut flora composition could further weaken the intestinal barrier and exacerbate the risks associated with leaky gut syndrome.
“The implications of these findings are far-reaching. As space agencies like NASA and SpaceX set their sights on more ambitious missions, including the prospect of manned missions to Mars, the health and well-being of astronauts are of utmost importance.
“This study underscores the urgent need for targeted research to understand and mitigate the health risks associated with space travel. It is imperative that we develop strategies to maintain gut health and prevent the adverse effects of altered gut permeability. These strategies could be crucial for the success of future space missions, particularly those of longer duration.”
