Insulin is an important metabolic hormone. Made in your pancreas, insulin is produced after eating in order to move the sugar from your blood into your cells for future energy use. If we eat too much, especially sugar and starchy foods, our bodies are flooded with insulin and over time our cells become resistant to the effects of insulin, leaving high levels of sugar and insulin in the bloodstream.

What might a low result mean?

A low insulin result can indicate type 1 diabetes, an autoimmune condition which means that the pancreas can no longer produce insulin. If no insulin is present to move glucose from your blood into your cells, then blood sugar can rise rapidly leading to symptoms of excessive thirst, frequent urination and fatigue. People with type 1 diabetes will need to inject insulin for the rest of their lives in order to control their blood sugar.

What might a high result mean?

Raised insulin can mean that you are becoming insulin resistant which is a pre-diabetic condition.

How might I improve my result?

Elevated insulin is a marker for pre-diabetes and diabetes as it signifies that your body is becoming less efficient at moving sugar from your blood into your cells. Controlling your blood sugar will also improve your insulin levels. Studies have shown that blood sugar and insulin both improve through weight loss achieved through calorie restriction. Eating a diet low in sugar and refined carbohydrates, high in whole grains, fruit and vegetables can also help improve insulin levels. Insulin sensitivity (how sensitive the body's cells are to the effects of insulin) can also be improved through exercise as well as getting sufficient sleep.
