Although we have many types of bacteria throughout our whole body, gut bacteria that lines the digestive system and lives in the intestines and colon may have the biggest impact on your health. These bacteria affect everything from your metabolism, your mood, to your immune system. Gut bacteria paired with other small organisms come together to make up the unique microbiome of every person. In a healthy person, the microbiota will help protect the body from disease causing organisms, such as through contaminated food or water.
Family genes, the environment, medication use and diet all play a role in that type of microbiota that live in your gut.

People who are sick or have contracted certain diseases have different sorts of gut bacteria compared to healthy people. Some illnesses that research has found links to the bacteria in your gut include.
Probiotics are foods or supplements that contain tiny organisms that are supposed to improve the “good” bacteria in the body.
