The gut microbiome, located inside the intestines, is home to a diverse population of microorganisms. This ecosystem includes various types of bacteria, viruses, fungi and parasites.
The creation of this ecosystem begins at birth. Whether through vaginal birth or breastfeeding, we are initially introduced to bacteria that will grow in our guts. As we age, our diet and environment continue to introduce new bacteria into our gut microbiome. These exposures can either help or harm the health of our gut.
Imagine your body as a house. You as the homeowner, are responsible for maintaining the living space to make sure your household runs efficiently. Your house also has a network of pipes and wires that keep the lights on and the water running behind the scenes. Your body’s internal ecosystem, the gut microbiome, is the system behind the scenes that helps your digestion, immune system, metabolism, and even out mental health and mood going!
Let’s take a closer look at the systems that the gut microbiome directly impacts:
Digestive System: Bacteria in our gut helps our digestive system break down micronutrients, complex carbohydrates, and dietary fiber. This process helps us fully digest our food and retain essential nutrients.
Immune System: The gut microbiome supports our immune functions. Did you know that your gut is the largest immune system organ, housing 80% of our bodies immune cells? These cells help remove germs that pass through our system every day.
Nervous System:The gut microbiome affects our nervous system through the gut-brain axis. Ever had a “gut feeling”? If so, you have experienced the network of nerves, neurons, and neurotransmitters between your brain and gut communicating. The health of our gut microbiome impacts their ability to communicate. Additionally, the bacteria in our gut stimulates the production of feel good hormones (like serotonin) that can impact our mood and mental health.
An unhealthy or unbalanced gut microbiome could mean a loss of healthy bacteria, an overgrowth of bad bacteria, or a loss of bacteria diversity. Some signs that you may have an unbalance microbiome include:
- Gas and gas pain.
- Bloated stomach.
- Poor digestion.
- Lower abdominal pain.
- Diarrhea or constipation
