There are many causes of insulin resistance and the underlying process is still not completely understood. Risk factors for insulin resistance include obesity, sedentary lifestyle, family history of diabetes, various health conditions, and certain medications. Insulin resistance is considered a component of the metabolic syndrome. Insulin ...
Also, some causes of insulin resistance, like pregnancy, are temporary. ... Experts believe excess body fat, especially excess visceral fat around the internal organs, is the main cause of insulin ...
There is debate regarding whether obesity or insulin resistance is the cause of the metabolic syndrome or if they are consequences of a more far-reaching metabolic derangement. Markers of systemic inflammation , including C-reactive protein , are often increased, as are fibrinogen , interleukin 6 , tumor necrosis factor-alpha (TNF-α), and others.
Prediabetes –; Main types of diabetes: Type 1 diabetes – disease that results in autoimmune destruction of insulin-producing beta cells of the pancreas. [4]Type 2 diabetes – metabolic disorder that is characterized by high blood glucose in the context of insulin resistance and relative insulin deficiency.
Stress also increases insulin resistance, which can spike your blood sugar and cause weight gain, adds Alexander. "Acute stress isn't going to do that, but chronic stress can."
Age-related diseases can promote insulin resistance, which is an underlying cause of a number of medical conditions. Plus, resistance to insulin-induced cell stress decreases with age .
Type 2 diabetes is due to insufficient insulin production from beta cells in the setting of insulin resistance. [13] Insulin resistance, which is the inability of cells to respond adequately to normal levels of insulin, occurs primarily within the muscles, liver, and fat tissue. [60] In the liver, insulin normally suppresses glucose release.
The influx of Ca 2+ ions causes the secretion of insulin stored in vesicles through the cell membrane. The process of insulin secretion is an example of a trigger mechanism in a signal transduction pathway because insulin is secreted after glucose enters the beta cell and that triggers several other processes in a chain reaction.
