From what I know, Syndrome X is insulin resistant..... type 2 diabetes usually respond to insulin. My body makes insulin, but it doesn't respond. My mom has type 2 also, but her body doesn't make it and it responds to injected insulin
Syndrome X is a mix of 2 or more health conditions related to being overweight or obese. They are: high cholesterol, high blood sugar (including "pre-diabetes"), high blood pressure, high triglycerides, high uric acid, and a couple of others.
Most people with diabetes (Type 2) have some of these other conditions related to being fat.
