Excess insulin is also implicated in cardiovascular disease and certain cancers. Interestingly, some of the risks associated with high IGF-1 are thought to be mediated through its effect on insulin signaling, highlighting the interconnected nature of these two systems.

It promotes cell proliferation, differentiation, and inhibition of apoptosis. While insulin manages the immediate needs of the body regarding energy, IGF-1 is crucial for long-term growth during childhood and has significant anabolic effects in adults, including muscle hypertrophy and bone density maintenance.
Structurally, IGF-1 is remarkably similar to insulin, sharing about 60% amino acid homology, which allows it to interact with the insulin receptor, albeit with lower affinity. Activation of IGF-1R initiates pathways like the MAPK/ERK cascade, which is more directly involved in cell growth, proliferation, and gene expression.
How Insulin Spikes After Eating Tie Into IGF-1 and Health Risks
Its primary function is to facilitate the uptake of glucose into cells, particularly in muscle and adipose tissue. Primary Physiological Roles The primary role of insulin is metabolic regulation.
