Colectomy is a surgical procedure to remove all or part of the colon. When only part of the colon is removed, it is called a partial colectomy. The procedure is also known as a bowel resection. The colon is part of the body's digestive system.
The use of potassium-sparing diuretics is contraindicated in patients with anuria, acute or progressive renal insufficiency, or diabetic nephropathy. Potassium-sparing diuretics can cause hyperkalemia, which may result in life-threatening cardiac arrhythmias. Careful monitoring of serum potassium levels is necessary in all patients treated with potassium-sparing diuretics, especially during initiation of therapy, after dosage adjustment, and during illness that could alter renal function.
(See Causes of hyponatremia in adults and Causes and evaluation of hyperkalemia in adults and Diagnostic evaluation of adults with hyponatremia.) HYPONATREMIA AND HYPERKALEMIA. Hyponatremia and hyperkalemia are the two major electrolyte abnormalities of primary adrenal insufficiency. Hyponatremia is mediated by increased release of antidiuretic hormone (ADH) which results in water retention and a reduction in the plasma sodium concentration [3,4].
