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.
Possible side-effects of Â­diuretic include: 1  an increased need to go to the toilet. 2  feeling thirsty, dizzy, weak, lethargic or sick. 3  low blood pressure when moving from lying or sitting to standing. 4  muscle cramps. 5  skin rash. 6  raised uric acid levels (that can lead to kidney problems and gout) 7  raised blood sugar levels.
