- The glycohypoxia hypothesis links chronic hyperglycemia in type 2 diabetes to functional hypoxia by impairing oxygen release from hemoglobin.
- Non-enzymatic glycation of hemoglobin may lock it in a high-affinity state, reducing oxygen unloading and affecting the oxyhemoglobin dissociation curve.
- Hyperglycemia-induced osmotic stress and the polyol pathway contribute to cellular swelling, reactive oxygen species generation, and mitochondrial dysfunction.
- Insulin resistance exacerbates hyperglycemia and limits ATP synthesis, activating hypoxia-inducible factor-1α and promoting complications like retinopathy and nephropathy.
- Potential therapeutic strategies include anti-glycation agents, polyol inhibitors, and GLUT-4 agonists to restore oxygen unloading and improve diabetes management.
