Insulin resistance manifests in non-obvious physical signs long before blood sugar becomes abnormal. These include skin tags, velvety darkened skin on the neck (acanthosis nigricans), and loss of hair on the toes. These are early warning signs of metabolic dysfunction that can be visually identified.

Many clinicians mistakenly believe insulin's main role is blood glucose control. In reality, it's a master hormone signaling every cell—from brain to bone—to store energy. This function is so powerful it can slow the body's overall metabolic rate to prioritize energy storage.

The entire system of prenatal and postpartum care is fundamentally designed as a triage mechanism. Since roughly 75% of pregnancies are uncomplicated, its primary purpose is not to medicalize a natural process, but to efficiently identify and manage the 25% of cases that will face complications.

Many chronic illnesses, including high blood pressure, cancer, and cognitive decline, are not separate issues but symptoms of a single underlying problem: chronically elevated insulin levels. This metabolic “trash” accumulates over years, making the body a breeding ground for disease.

The idea of preventing disease by managing measurable risks like cholesterol was a paradigm shift in medicine, born from observing 5,000 residents of Framingham, MA over decades, an unprecedented study that began in 1948.

The vascular damage from sugar is direct and chemical. Excess glucose acts like glue, binding to and disabling the very enzymes that produce nitric oxide. This shuts down the body's ability to dilate blood vessels, leading to a cascade of health issues like hypertension and peripheral neuropathy.

Diet during pregnancy doesn't just build a baby; it actively programs their DNA by placing epigenetic "switches" on genes. These switches influence the baby's future risk for diseases like diabetes, obesity, and even psychiatric disorders, shaping their health for life.

Only 7% of US citizens are metabolically healthy, meaning 93% have at least one biomarker of metabolic syndrome (e.g., pre-diabetes, high blood pressure, abdominal obesity). This widespread metabolic ill-health provides a strong biological basis for the escalating mental health crisis.

For select patients who find frequent lab checks for hyperglycemia monitoring to be a significant barrier, a continuous glucose monitor (CGM) can be a practical alternative. While off-label, it provides valuable data for management in patients who might otherwise be non-adherent with monitoring.
