The Connection Between Being Overweight and Type 2 Diabetes

Type 2 diabetes happens when your body has trouble using insulin, a hormone that controls your blood sugar levels. Being overweight, especially having too much fat around your belly, makes it harder for your body to use insulin properly. Here's why:

  1. Fat Tissue Trouble: Fat isn't just something that sits there; it's active and releases hormones and other substances. When you have too much fat, especially around your belly, it releases stuff that messes with how insulin works in your body.
  2. Insulin Resistance: Your body's cells, like those in your muscles and liver, start ignoring insulin when there's too much fat around. This means they don't take in sugar from your blood as they should, leading to higher blood sugar levels.
  3. Inflammation: When you're overweight, your body is in a constant state of low-level inflammation. This inflammation makes it even harder for insulin to do its job, leading to more trouble with blood sugar control.
  4. Too Much Fat in the Wrong Places: Having too much fat in places where it shouldn't be, like inside your muscles and liver, also messes with insulin's actions. This can further worsen insulin resistance and make it harder for your body to control blood sugar.
  5. Gut Bugs: Believe it or not, the bacteria in your gut can play a role too. Changes in the types of bacteria living in your gut, often seen in overweight people, might make it harder for your body to manage blood sugar levels.
