The Claim

In hypertensive patients with fasting glucose levels ≤125 mg/dL, a 1-standard deviation increase in the triglyceride-glucose (TyG) index is associated with a 6.3% reduction in post-occlusive reactive hyperemia (PORH), independent of traditional cardiovascular risk factors.

In plain English

Among hypertensive individuals with normal fasting blood sugar, higher levels of the triglyceride-glucose index are linked to reduced blood flow response in skin capillaries after temporary blood flow blockage, regardless of standard heart disease risk factors.

See the scientific wording

In hypertensive patients with fasting glucose levels ≤125 mg/dL, each 1-standard deviation increase in the triglyceride-glucose (TyG) index is associated with a 6.3% reduction in post-occlusive reactive hyperemia (PORH), indicating a link between metabolic dysfunction and impaired skin microvascular reactivity independent of traditional cardiovascular risk factors.

Why this might work

When the body becomes resistant to insulin, it triggers inflammation and stress that reduce the number of repair cells in the blood. These repair cells normally fix tiny blood vessels in the skin. With fewer of them, the vessels cannot respond properly when blood flow is temporarily blocked and then restored, leading to weaker blood flow recovery.

  1. Study: Insulin Resistance is Associated With Skin Microvascular Dysfunction and Reduced Circulating Endothelial Progenitor Cells in Hypertensive Patients

    In people with high blood pressure and normal blood sugar, higher levels of a blood marker called TyG are linked to worse blood flow in tiny skin vessels after a cuff is released — meaning metabolic stress may harm small blood vessels even before diabetes shows up.
