Researchers recently published a study in the Nature Genetics journal that highlighted that depression may be caused by two kinds of bacteria that live in the colon. The study analyzed the health data of 6,000 people in Finland, which compared their gut microbiota, genetics, lifestyle and diet. It was found that people with higher amounts of the bacterial strains Klebsiella and Morganella in the colon, both of which are considered unfriendly, may be more prone to depression. The Klebsiella pneumoniae strain in particular is considered one of the most dreaded germs in hospitals, due to its antibiotic resistance and ability to cause extensive damage to patients health. Both species create toxic chemicals within the body, that can cause inflammation in the nervous system, and elsewhere.
The research comes shortly after scientists also recently discovered that a greater amount of unfriendly bacteria in the bowels may also be responsible for long COVID-19 symptoms.
In the past doctors had noticed the link between depression and poor bowel health, with symptoms such as bloating, constipation and other problems common in those with problem. However they are realizing now that the bowel may the the actual cause, as opposed to the other way around.
By performing a good quality detox at least once a year, it helps to rid the bowel of material, such as mucoid plaque and food waste, that could otherwise provide a fertile breeding ground for unfriendly pathogens, which can wreak extensive damage on the body and mind.
