What is
insulin-like growth factor 1?

Insulin-like growth factor 1 (IGF-1), also known as somatomedin C, is a hormone which helps to control how rapidly your body's cells grow and reproduce.

What causes
elevated IGF-1?

Although a high level of IGF-1 is necessary for growth in children, high IGF-1 in adults is associated with the reproduction of cancer cells and the ageing process. There is a link between high IGF-1 levels and high protein intake.

Why take an
IGF-1 blood test?

IGF-1 blood tests help diagnose growth abnormalities and evaluate pituitary function. However, you may want a blood test to measure your IGF-1 if you are about to start a programme of intermittent fasting or if you have already been intermittent fasting and would like to assess the effect it has had.
