When over expressed, as when exposed to an excessive amount of reactive oxygen species, it causes chronic inflammation and is implicated in many different conditions, from cancer, to alzheimers, to rheumatoid arthritis, to IBS, as well as COPD and other lung diseases
At 20 years, levels average around 200 ng/ml, while studies document concentrations drop to approximately 80 ng/ml by age 60[2]
In this review we discuss the relevant actions of IGF-1 on metabolism and the implication of IGF-1 deficiency in the establishment of metabolic syndrome
