Molecular Mechanisms: How Smoking Triggers Insulin Resistance

Insulin resistance events when n cells in muscle, liver, and adipose tissue lose their ir sensitivity to insulin 's signal to absorb glucose from the blootream. Smoking akcelerates this process thugh multiple convergent pathays, creating a metabolic environmental that progressively degres glycemic control.
