Modulating gut microbiota using probiotics, prebiotics, antibiotics, or fecal microbiota transplantation improves glucose metabolism and insulin resistance in type 2 diabetes.

If you have type 2 diabetes, your gut bacteria play a key role in how your body handles sugar and insulin. You can positively influence these bacteria through specific probiotics and prebiotics (like those found in certain fermented drinks or fibers), which may help lower fasting blood sugar and improve insulin sensitivity. While not a cure, this is a valid therapeutic strategy alongside standard care.
