Gut bacteria could determine whether you develop PTSD

Posted by: | November 3, 2023 | Comments

Molecular Biologists found that you’re more likely to develop PTSD if you lack in certain immune supporting bacteria

The bacteria living in your gut could tell you whether you are at risk of developing post-traumatic stress disorder (PTSD). New research has suggested that people living with PTSD have low levels of bacteria that help with fighting infections.

Molecular biologists from Stellenbosch University analysed microbial DNA that they extracted from stool samples of people with PTSD and those who experienced trauma but haven’t developed the disorder. They found that individuals with PTSD had lower levels of three specific gut bacteria.

The bacteria, called Actinobacteria, Lentisphaerae and Verrucomicrobia, support the functioning of the immune system. “We were interested in what these three bacteria mean in terms of PTSD,” says lead researcher of the South African study, Stefanie Malan-Muller. “We hypothesise that people with PTSD struggle to regulate their immune system functioning, and they often have high levels of inflammation.”
