Document Summary
Diabetes mellitus - the disorder of carbs, fat & protein metabolism with absolute or relative insulin deficiency. Triggers/underlying etiology of acute complications often includes: concurrent illness and factors related to the management of plasma glucose levels including noncompliance with diet or pharmacology therapy or side effects of pharmacological therapy. Triggers/underlying etiology of chronic complications often includes: chronic hyperglycemia & the resultant metabolic events. Hyperglycemia affects cells that don"t effectively reduce the transport of glucose into the cell in a hyperglycemic state resulting in intracellular hyperglycemia. Cells that are vulnerable to chronic hyperglycemia include: Neurons & shwann cells in the peripheral nerves. Plasma glucose varies based on the last meal; homeostatic mechanisms of the body generally maintain glucose at a level <6. 0 mmol/l. Hypoglycemia - the development of neurogenic/autonomic and/or neuroglycopenic symptoms. Activation of the sympathetic nervous system results in the neurogenic/autonomic symptoms of trembling, palpitations, sweating, anxiety, hunger, nausea, and tingling.
