Cushings Disease


Hypercortisolism; Cushing’s Syndrome; Adrenocortical Hyperfunction


Cushing’s disease reflects an excess of cortisol. Depending on the cause of the disease, mineralocorticoids and androgens also may be secreted in increased amounts. The disorder may be primary (an intrinsic adrenocortical disorder [e.g., neoplasm]), secondary (from pituitary or hypothalamic dysfunction with increased adrenocorticotrophic hormone secretion resulting in glucocorticoid excess), or iatrogenic (from prolonged or excessive administration of corticosteroids). The disease results in fluid and electrolyte disturbances, suppressed immune response, altered fat distribution, and disturbances in protein metabolism. Changes in physical appearance that occur with Cushing’s disease can have significant influence on the patient’s body image and emotional well-being. The focus of this care plan is on the ambulatory patient with Cushing’s disease.




Diabetes Mellitus


Type 1; Type 2


Diabetes mellitus is a disorder of metabolism in which carbohydrates, fats, and proteins cannot be used for energy. Insulin, a hormone secreted by islet cells of the pancreas, is required to facilitate movement of glucose across cell membranes. Once inside the cell, glucose is the primary metabolic fuel. Type 1 diabetes occurs when the pancreas is no longer able to secrete insulin. This condition occurs as a result of an autoimmune process with destruction of pancreatic beta cells and has its onset between ages 1 and 24 years. The autoimmune process is triggered by a combination of genetic predisposition and environmental stimuli such as a virus. The result of the insulin deficiency is hyperglycemia. It represents 5% to 10% of the cases of diabetes. Type 2 diabetes results because of resistance of peripheral tissue receptors to the effects of insulin. This type of diabetes also has a genetic predisposition for insulin resistance in skeletal muscles, fat cells, and liver cells. Type 2 diabetes is characterized by hyperinsulinemia and hyperglycemia. Over time the beta cells of the pancreas fail to produce sufficient insulin. Its onset is slow and gradual, with many individuals having had the disease 10 years before diagnosis. It represents 90% to 95% of the cases of diabetes. This is usually a condition of middle-aged to older individuals, although a recent increase in the incidence of type 2 diabetes has occurred in children. Obesity is a major factor in the development of type 2 diabetes in both children and adults. Current studies relate waist circumference of 40 inches for men and 35 inches for women to increased risk for this form of diabetes.


Diabetes is a major public health problem; more than 16 million individuals, or 6.5% of the population, have the disease. Diabetes causes significant morbidity and mortality. Seventy percent of diabetes-related deaths are from cardiovascular disease. The severity of dyslipidemia and hypertension is higher in the person with type 2 diabetes. Diabetes is the most common single cause of end-stage renal disease in the United States. Diabetic retinopathy is the most frequent cause of new cases of blindness among adults 20 to 74 years of age. Diabetes is the leading cause of nontraumatic lower extremity amputations in the United States. This care plan concentrates on the care of individuals with type 2 diabetes.




Hyperthyroidism


Graves’ Disease


Hyperthyroidism occurs as a result of increased circulating levels of thyroid hormones. Women are affected more often than men. The peak age for diagnosis of the disorder is 20 to 40 years. The most common cause is Graves’ disease. This form of hyperthyroidism is an autoimmune disorder that contributes to a failure of the normal regulation of thyroid hormone secretion. Other causes of hyperthyroidism include toxic multinodular goiter, thyroid gland tumors, and pituitary gland tumors. The clinical manifestations of hyperthyroidism develop as a result of the hypermetabolic effects of increased thyroid hormones on all body systems. These manifestations include heat intolerance, irritability, restlessness, goiter, tachycardia, palpitations, increased blood pressure, diaphoresis, weight loss, increased appetite, diarrhea, visual changes, menstrual irregularities, and changes in libido. Thyrotoxic crisis or thyroid storm is a rare but severe form of hyperthyroidism that develops suddenly in response to excessive stress or poorly controlled hormone levels. The management of hyperthyroidism includes drug therapy, radioactive iodine therapy, and surgical removal of all or part of the thyroid gland.
