Anxiety May Originate In Your Gut

Posted on May 19, 2015

Have you ever felt anxiety fluttering its relentless wings in the center of your stomach? It might not be simple nervousness. The human gut is often called the "second brain," and for very good reason. Research has begun to understand the link between mood and behavior and how they are directly affected by the bacteria in the gut.

Bacteria in the gut are responsible for a number of metabolic and biological process within the body. Brain health and mood stabilization is something that is deeply affected by the balance of good bacteria in the intestines. A study from McMaster University recently verified this notion, observing just how powerful the gut is at influencing brain chemistry and behavior.

In the study, researchers disrupted normal gut bacteria count in healthy mice by administering antibiotics, bacteria-killing medicines that destroy all bacteria in its path — including good bacteria. Following disruption of the normal flora balance, mice became less cautious, and changes in the animals’ brain-derived neurotrophic factor — a protein associated with mood disorders — increased significantly. Upon discontinuing antibiotics, gut bacteria normalized and brain chemistry was restored to pre-study levels.

Researchers in this study noted that, while many factors play a role in dictating mood and mental health, bacteria in the gut strongly influences behavior and can be noticeably disrupted during antibiotic administration. This conclusion leads many to believe that the use of probiotics, beneficial bacteria found to influence serotonin levels, the immune system, and digestion, may be a helpful therapeutic tool for behavioral disorders.
