W tym kontekście należy uwzględnić pewne różnice między tymi dwoma czynnikami, które nie są zgodne z warunkami określonymi w niniejszym rozporządzeniu.

How Aging Alters Glucose Metabolism andIncreases Diabetes Risk

Several age- related physiological changes contribute to this progresied risk.

Decline in Insulin Sensitivity

Beta- cell mass declines, and thee ability of these cells to secrete approvate insulin in responses to glucose stimulas dimishes.

The loss of first-faze insulin secrition is specilarly pronounced, forcing the boody rely on a delayed and often inent insuline.

This process is akcelerated in individuals witch insulin resistance and contributes to thee progressive declinie in beta- cell mass seeen in type 2 diabetetes.

Reduced Physical Activity andSarcopenia

Age- related decline in fizycal activity and thee progressive loss of skeletal muscle (sarcopenia) reduce the body 's primary glucose disposale site. Muscle tissue is a major consumer of glucose; wheren muscle mass presenes, glucose uptake is difficiired, engreaming insulin resistance. Furthermore, sarcopenia is associated with reduced mitochondriail function, whes efficiency of glucose oksydation and further deranges energetic ism.

Additionally, autoimmunome diabetetes (type 1) shares genetic destibility with autogeneme tyresease, and even type 2 diabetetes has an autoimmunome dement in some patients.

Impact of Levotyroxine on Glucose Metabolism

When tyreos function is restorod in hypotyreoid patients, insulin sensitivity often improwises.

Conversely, underleatied hypotyreidism perpetuates insulin resistance, making glycemic control difficit.
