There is a communication between the microbiotas of the gut and lungs.
All the microorganisms that are naturally found in and on the human body are called the microbiota. These include mostly bacteria, viruses and fungi. The microbiota has been shown to have a vital role in health, including immunity.
The Gut-Lung Axis
Airway and lung microbiota
There is a diverse population of microbes found throughout the upper respiratory tract and lower respiratory tract. These have been shown to interact with immune functions.
Recent evidence describes the cross-talk between the microbiotas of the gut and lungs. Changes in lung microbial community influence the composition of gut microbiota and vice versa, influencing respiratory health.
Disruptions in gut and lung microbiota have been linked to respiratory diseases including viral respiratory tract infections, asthma, chronic obstructive pulmonary disease (COPD) and lung cancer.
Gut microbiota regulates the immune system and protects against harmful pathogens. As we grow, our microbiota and immune system shape the development of each other.
