How Important Are the Bacteria Living in Your Bowels?

It is estimated that there are ten times as many bacteria in the human body as there are in human cells.  This shows that there is a huge number of bacteria in your body. A majority of these bacteria are found in your digestive passageway. We were made to believe that bacteria are harmful to your body. But is this really entirely true?  Let’s take a look at some of the benefits of bacteria in your bowel.

  • Assists your immune system: Your intestines send a signal to the bacteria and vice versa. The signal received allows the body to regulate itself based on what is happening to your body. It gets the immune system ready for any traces of toxins in your body.
  • Influences your health: According to Tillisch Kirsten, the bacteria determine whether you will develop inflammatory bowel disease or infectious colitis. The identification of the bacteria in your bowel can be used to know diseases you are likely to have. Some of the health issues associated with bowel bacteria are cancer, obesity, cancer and depression.
  • Help your body to adapt: Since we constantly ingest food, bacteria, and viruses, they accumulate in your guts. They interact with the lining of your intestine that is filled with immune cells. These immune cells constantly change to adapt with the bacteria. Hence, they make your body adapt to what you ingest.
  • Stimulates the production of antibodies in your blood: The bacteria contribute to the strength your immune system. In fact, it is believed that someday they will be used as treatment. The treatment can be achieved with the use of bacteria spores. These spores will help to boost your immune system. This form of treatment will be particularly useful for the newborns and the elderly ones.
  • Regulates your weight: Some researchers have suggested that the bacteria in your bowel have an influence on your weight. Besides, a recent study concluded that people who are obese have less diversity in their bowel bacteria than ordinary people. An increase in a group of bacteria known as Firmicutes and a decrease in another group known as Bacteroidetes has been linked to obesity, too. This implies that the bacteria in your gut can be altered to regulate your weight. In order to achieve this, the ratio of the Bacteroidetes to the Firmicutes has to be altered.
  • Have direct effects on the brain: There have been speculations that bowel bacteria can affect the brain. Studies carried out on animals have also suggested something similar. A particular study conducted on mice in which they were given antibiotics shows this. It was discovered that the mice became less anxious when they were given antibiotics. Once the gut bacteria were restored, they became anxious again. This suggests that the bacteria have effects on your brain.


Nature does not just put some things in place without reasons. The many bacteria in the human body have their functions there. They help in your digestion process as well as keeping your health in check.
