Gut bacteria is responsible for developing white blood cells which strengthens the overall immune system and that is why it’s important to keep your gut as healthy as possible. Gut bacteria develops white blood cells called macrophages, monocytes and neutrophils which all defend against pathogens.
Over the span of our lives, we are introduced to new things through our guts, noses and lungs from the things we eat, the places we go and the activities we take part in. To do these things, you must have a healthy balance between tolerance and reaction which is what your immune system aims to provide.
At a young age, your body will work to develop a diverse gut flora which consists of bacteria, fungi and other microorganisms. Because our gut bacteria influences our immune systems, having an unbalanced bacteria flora can put your immune system in an inflammatory state. This can lead to obesity, diabetes and depression.
The majority of bacteria are beneficial, but some are the root cause of disease. Your gut contains trillions of microbes that collectively make something called the gut microbiota. The gut microbiota is responsible for various aspects of the human body including metabolism, the cardiovascular system, nervous system and the immune system.
The immune system’s duty is to protect against diseases such as infectious microbes. Throughout our lifetimes, our immune systems have evolved just like our gut floras.
Our immune systems and gut microbiota work together to regulate one another, and this is made possible because up to 80 percent of the body’s immune cells are found in the gut. Since birth, the microbiota and immune system have learned to interact in ways to keep their host (yes that’s your body) safe and healthy.
When they work together properly, the immune system will help the good microbes grow and a healthy microbiota will help develop immune cells which in turn, create positive responses. Your gut microbiota and immune system will protect against pathogens and harmless microbes while maintaining self-tolerance.
You can promote your gut health by following a healthy diet. Being in control of your health and diet will protect you against disease. While everyone has different genetics and requirements, having an optimal gut lining is necessary for creating a strong gut microbiome.
The Intestinal Barrier
The gut microbiota communicates with the body through the intestinal wall. The wall acts as a barrier against gut microbes, pathogens and infected cells while promoting the gut flora.
Micro metabolites are good for the body and they get absorbed here through the intestinal barrier. These promote development, function, circulation and maturation in all of the body’s organs.
These metabolites allow the gut microbiota to create immune responses. Immune cells are also responsible for maintaining the intestinal wall. Overall, a strong immune system and brain are thanks to the intestinal barrier which allows good gut molecules to enter the body while keeping the other bad ones out. Your gut and your immune system would not be able to communicate without your intestinal barrier.
Connection Between the Gut and the Rest of the Body
The signals between the gut and other parts of the body that travels through neurons, hormones and the immune system are also known as ‘axes.’ These axes act as the communication between your gut, the body and if you have a disease. Many people who suffer from inflammatory bowel disease can often suffer from depression as a result. This is because the gut has the ability to alter the brain’s chemistry through neuronal pathways and the immune system’s cytokines.
These rely all on the state of the gut microbiota and something that commonly impacts the gut microbiota is stress. When you’re in a stressful situation, your brain may trigger pain in your gut, causing bloating or discomfort. Stress can change the nervous system and how it reacts. These changes can sometimes later lead to gut diseases and dysfunction.
The gut is also responsible for fat components and antigens which also impacts the risks of liver disease. Gut microbiota also influences asthma, pneumonia and some cancers. The human body consists of thousands of different microbes that make up the microbiome. Studies have revealed gut microbes are linked to autism, multiple sclerosis and inflammatory bowel disease.
