Studies Say Depression May Be Linked To Your Gut Bacteria
Depression is generally of a disorder of the brain. But a new research has claimed that it is linked to the gut too. The study published on December 6th in Nature Communications suggests that a human’s gut microbiome and depression could be related.
A microbiome refers to all the microbes or microorganisms that live in your body. Gut microbiome is the colony of microorganisms in your stomach and intestines. It performs a lot of important functions for your body, which includes the brain too.

The recent studies have pointed to the fact that certain strains of bacteria in the gut might aggravate depressive symptoms while other strains might decrease them.
In the two studies, researchers found out 13 varieties of bacteria that were positively related with depressive symptoms. In some people with depression, gut bacteria was less, while in others, it’s level was too high.
Ultimately, the researchers found out that an individual with a highly diverse gut microbiome has a lesser chance of experiencing depression. The experts, however, have said the discovery doesn’t actually prove that a particular microbe causes or shields against depression.
Director of the Oppenheimer Center for Neurobiology of Stress at the University of California, Dr. Emeran Mayer, said that the bacteria in the gut change in quantity and diversity in the presence of any chronic illness. He also stated that the findings might be relevant to all the diseases in general and not only depression.
These groundbreaking findings from the study may prove to be very useful in gaining more insights on depression and it’s treatment. There are a lot of things still unknown about the disorder and if the gut and depressive symptoms are really linked, it would help in developing new treatment options.
