Insulin resistance is closely linked to a cluster of systemic conditions including hypertension, dyslipidemia, fatty liver, and polycystic ovary syndrome.

Beyond elevated blood glucose, insulin resistance disrupts multiple metabolic pathways, contributing to hypertension and abnormal blood lipids, collectively termed metabolic syndrome. It also promotes fat accumulation in the liver (nonalcoholic fatty liver disease) and hormonal imbalances causing polycystic ovary syndrome in women, highlighting its broad systemic impact.
