The immune system is our body's defense mechanism against foreign and harmful invaders. A significant part of the immune systen is intertwined with the bacteria in your gut, whereby good bacteria helps fend off harmful viruses, bacteria and fungi. With an unhealthy gut, there is a lack of good bacteria which weakens the immune system.

The digestive system is primarily in charge of the digestion of food and absorbtion of nutrients which happens in the gut. An imbalance of the good an bad bacteria in your gut will affect the digestive processes, which in turn can lead to numerous conditions such as high blood sugar, high cholesterol, weight gain and other conditions.

Hormones are essential in ensuring the processes in your body work seamlessly. An imbalanced gut impacts hormone production and regulation which in turn leads to disturbance in the bodily process. For example, the hormone called serotonin which acts as a mood stabiliser, is produced, and stored in the gut. Hence, an unhealthy gut has been shown to lead to feelings of depression and anxiety.

Your gut health will impact your metabolism as it regulates your glucose metabolism, appetite, and fat storage. It also regulates metabolic wastes and toxins. Therefore, an unhealthy gut will not be able to regulate these processes. This results in symptoms of chronic fatigue, inflammation, obesity, and others.
