Insulin is a hormone that helps to control the amount of sugar in the blood. Insulin resistance results in an abnormal response to insulin from the body's cells, resulting in higher than normal amounts of insulin being made in the body. Eventually, the body slows its production of insulin, leading to increased blood sugar levels. This can therefore result in a higher risk of developing impaired fasting glucose and therefore diabetes in the near future.
PCOS is a hormonal disorder affecting women, with a common characteristic being increased androgens or ‘male hormones’ that can prevent ovulation and affect menstruation. PCOS can also increase the risk of developing insulin resistance. The diagnosis of PCOS is complex and involves a medical history, examination, blood tests and ultrasounds.
