Endocrine and Metabolic DisordersFree Board Review Questions CME Quiz
The endocrine system is responsible for regulating a range of bodily functions through the release of hormones. Hormones are secreted by the glands of the endocrine system, traveling through the bloodstream to various organs and tissues in the body. The hormones then tell these organs and tissues what to do or how to function. Endocrine systems play a major role in the protection against acute elevations in serum potassium by means of insulin action and adrenergic modulation of extrarenal potassium disposal. Aldosterone is recognized as the delayed regulator of potassium excretion. Magnesium levels fall in hyperaldosteronism, hyperparathyroidism, and diabetic keto-acidosis, as well as in malnutrition states. The integrated action of these hormones and electrolytes are thus of major importance in regulation of the cardiovascular system. Endocrine disorders and metabolic result in certain hormones being too high or too low which can have a number of effects on health. The signs and symptoms depend on the hormone that’s out of balance.
