Metabolic syndrome is primarily caused by obesity and inactivity.
Metabolic syndrome is linked to a condition called insulin resistance. Normally, your digestive system breaks down the foods you eat into sugar (glucose). Insulin is a hormone made by your pancreas that helps sugar enter your cells to be used as fuel.
In people with insulin resistance, cells don't respond normally to insulin, and glucose can't enter the cells as easily. As a result, glucose levels in your blood rise despite your body's attempt to control the glucose by churning out more and more insulin.
This can eventually lead to diabetes when your body is unable to make enough insulin to keep the blood glucose within the normal range.
