Intestinal Bacteria: A Possible Basis For Future Obesity Treatments
Obesity is a global health problem that has a multifactorial etiology. Among the suspected and studied factors are intestinal bacteria.
Human beings contain a huge amount of bacteria in our body that help us to perform numerous functions -such as digestion-, or that protect us from other bacteria capable of causing disease. Some of them are intestinal bacteria.
Gut bacteria make up the gut microbiota. It is a set of microorganisms that live permanently in our digestive tract. It is made up mostly of bacteria, but there can also be viruses and fungi.
This intestinal microbiota makes up almost 1.5 kilograms of our weight. According to scientists, these bacteria fulfill a multitude of functions, since they facilitate part of the metabolic reactions that we need to live, and also stimulate the immune system.
The role of these intestinal bacteria in aspects such as obesity is currently being studied. In this article we explain the latest that is known about this topic and why it may be a future treatment.
What is the function of intestinal bacteria?
As we have already mentioned, intestinal bacteria are microorganisms present in our digestive tract. They are of different species and, in addition, in each person there is a different intestinal microbiota.
Scientists have studied these differences between people to show what are the functions that these bacteria fulfill in our body. They have proven that having a healthy microbiota contributes to maintaining a balance throughout our body.
It seems that intestinal bacteria are decisive in metabolism. They appear to help regulate appetite and weight. Also the inflammatory process that is associated with obesity. They could even play an important role in stress management.
For example, healthy people have been found to have many bacteria of the genus Clostridium . However, those who have a problem with their immune system, have a much smaller number of these.
