===Pathology involving glucose===

When there is insufficient glucose in your body, a person may start experiencing the symptoms of [[hypoglycemia]]. Because the lack of glucose inhibits your cells from operating properly, you will feel fatigued, light headed, and nauseous. In most cases, the sympathetic nervous system is triggered resulting in tremors, nervousness, and anxiety. In extreme cases, people can go into comas.

When there is insufficient glucose in your body, a person may start experiencing the symptoms of [[hypoglycemia]]. Because the lack of glucose inhibits your cells from operating properly, you will feel fatigued, light headed, and nauseous. As a reflex action, the [[sympathetic nervous system]] is triggered into releasing [[epinephrine]] from the [[adrenal medulla]]. Epinephrine increases [[gluconeogenesis]], [[lipolysis]] and [[glycogenolysis]]. Ciculating ephinephrine may also result in tremors, nervousness, and anxiety. In extreme cases, people can go into comas as the principal source of energy for the brain is glucose.

A common disorder called [[diabetes mellitus]] is caused by a defect in normal glucose homeostasis. This occurs when one's body does not generate enough [[insulin]] due to autoimmune destruction of insulin secreting Beta-cells in the pancreas, or because body cells have been rendered "insulin resistant". The latter is precipitated by obesity or a genetic factor that causes dysfunctional cell signaling when insulin binds to its plasma membrane receptor.

A common disorder called [[diabetes mellitus]] is caused by a defect in normal glucose homeostasis. This occurs when one's body does not generate enough [[insulin]] due to autoimmune destruction of insulin secreting Beta-cells in the pancreas (termed Type I Diabetes Mellitus), or because body cells have been rendered "insulin resistant" (Type II Diabetes Mellitus). The latter is precipitated by obesity or certain genetic factors that cause dysfunctional cell signaling when insulin binds to its plasma membrane receptor.
