Bacteria in gut affect brain and behavior

Bacteria in the gut can influence brain chemistry, and behavior and drugs such as antibiotics can influence bowel functioning according to a new study in mice. The researchers showed that disrupting the normal gut flora of the mice leads to changes in the animals’ behavior, making them less timid and more adventurous, as well as leading to changes in their brain chemistry.

Another recent study shows the link between gut bacteria and stress response. The researchers have found that stress can alter the balance of bacteria that live in the intestine, leading to immune system problems.

So, using antibiotics not only can have an impact our moods and behavior but also on our immune system. You can read more on how gut bacteria can influence us in Gut Bugs Affect Brains and Stress wrecks intestinal bacteria, could keep immune system on idle.
