Chapter 19 Alterations of Hormonal Regulation
- Addison’s disease – (Adrenal Insufficiency)-
- - Autoimmune disorder where body creates antigens that attack the adrenal glands
- Cushings Syndrome- caused by chronic exposure to excess cortisol (too much steroid).
- Cortical hyperfunction (hypercortisolism) – DOES NOT involve the pituitary gland.
- Hypokalemia (decrease K), increase in Na+ resulting in ^BP, hyperglycemia, metabolic alkalosis (decrease H+)
Acromegaly- Hypersecretion of Growth Hormone-
o A disorder in adults in which the pituitary gland produces too much growth hormone
- Results from continuous exposure to high levels of growth hormone (GH) and insulin-like growth factor 1 (IGF-1); it almost always is caused by a GH secreting pituitary adenoma.
Pheochromocytoma - Chromaffin cell Tumors
- A hormone-secreting tumor (benign) that can occur in the adrenal glands (neuroendocrine tumor of the medulla of the adrenal glands).
- adrenal gland releases hormones that cause persistent or episodic high blood pressure, headaches
Thyroid Dysfunction- Hypothyroidism- Underactive Thyroid Gland
- deficient production of TH by the thyroid gland
- DX w/ blood test looks at T3, T4, and TSH Levels
Parathyroid Dysfunction- Hyperparathyroidism – Excessive Secretion of Parathyroid Hormone (PTH) by parathyroid gland
- Hyperkalemia ^Ca+ and Hypophosphatemia
Diabetes Mellitus (DM)- a group of metabolic disease characterized by hyperglycemia resulting from defects in insulin secretion, insulin action, or both.
- Body cannot properly use insulin leading to hyperglycemia
Type II Diabetes: ranging from predominantly insulin resistance with relative insulin deficiency to predominantly an insulin secretory defect with insulin resistance
Diabetes Mellitus- Assessment findings in hypoglycemia- reduction in plasma glucose concentration to a level that may induce symptoms or signs such as altered mental status and/or sympathetic nervous
Diabetic ketoacidosis – A serious diabetes complication where the body produces excess blood acids (ketones)-
