An imbalance in gut bacteria may cause the gut to leak toxins into the body, triggering inflammation and making it harder for the body to use insulin properly in people with type 2 diabetes.

The bacteria in your gut might affect your weight and blood sugar by changing how your body uses energy and handles inflammation.

The mix of bacteria in your gut might be connected to conditions like obesity and diabetes, and certain types of bacteria could be tied to storing more fat and how your body handles sugar.

Having a healthy mix of gut bacteria can help your body manage blood sugar better and respond more effectively to insulin.

When the good and bad bacteria in your mouth and gut get out of balance, it can trigger body-wide inflammation and leaky gut, which may raise your risk of heart disease.

Eating too much added sugar can irritate your gut, making it more oxygen-rich, which helps bad bacteria thrive and hurts the good ones—this imbalance might contribute to metabolic problems like obesity or diabetes.
