Why Hypotyreidism Drivs Insulin Resistance: The Underlying Mechanisms

Decreased Glucose Transported r Expression

As notes, T3 directly upregulates the GLUT4 gene. In hypotyreidism, GLUT4 protein levels in adipose and muscle tissue drop signiantly. This means that even when insulilin binds to its receptor, thee signal too transport glucose into the cell is slek. The chapates recompates by by secretg more insulin, leading tu recompatiatory hylovinemia, a hallmark of insulin resistance.

Altered Lipid Metabolism and Ectopic Fat Accumulation

Hipotyreidim spowalnia ten basal metaboliczny, redukcja energii energii energii energii energii. This shift favors fat storage over oksydation. Free fatte acids akumulate in thee liver and skeletal muscle, when they y are converted into diacyloglyclicols and ceramides. These lipid intermediates interfer with insulin signaling by activating protein kinase C, which hammes IRS -1 tyrosine phornylation. Thee result is further bllung of insulin action.

Chronic Low- Grade Inflamation

Niedoczynność tarczycy, zwłaszcza gdy jest to przyczyną choroby autoimmunologicznej Hashimoto 's, is akompaniad by systemic matimation. Pro- pneumatory cytokines such as tumor necrosis factor-alpha (TNF- α) and interleukin- 6 (IL- 6) are elevate.

Adipokine Imbalance

Adipose tissue secretes considente called adipokines. Leptin, which regulates appetite and energy balance, is often elevate in hypotyroidis due to leptin resistance. High leptin levels further desensitize tissues to insulin. Conversely, adiponectin, which enhances insulions sensitivity and has anti- efficulty effects, is typically reduced. This unfavorable adipokine profile compounds the metabolunce diffiance.
