A healthy microbiome can support people with diabetes by improving insulin sensitivity and reducing chronic inflammation. The production of short-chain fatty acids such as butyrate by certain gut bacteria promotes glucose metabolism and has anti-inflammatory effects. A balanced microbiome also helps with weight control, which reduces the risk of type 2 diabetes. By strengthening the intestinal barrier, it also prevents inflammatory substances from entering the bloodstream. This can contribute to better blood sugar control and mitigate blood sugar spikes. Overall, a healthy microbiome supports important processes for stabilizing blood sugar and can positively influence diabetes management.
