Calcium metabolism in subjects living with a permanent ileostomy
Abstract:
Several indices of calcium metabolism have been studied in 39 subjects living with a permanent ileostomy after proctocolectomy for ulcerative colitis, and in a control group of 39 healthy volunteers, matched for age and sex. No significant differences were found in plasma levels of calcium, phosphate, magnesium, parathyroid hormone, calcitonin and 25-hydroxy-vitamin D nor in the urinary excretion of calcium and phosphate, but the alkaline phosphatase was raised in the ileostomists. The bone density of the ileostomists was rather low, but the difference from the control subjects was not statistically significant. The absorption of calcium was measured by means of a total body counter. The ileostomists retained significantly more calcium than expected. It is suggested that this may represent the correction of a state of calcium deficiency at the time of proctocolectomy, due to the effects of the colitis and its medical treatment with corticosteroids.

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
01:24Ostomy Care
An ostomy is a surgical procedure that creates an artificial opening from the intestines to the outside of the body, allowing for the rerouting of effluent. This opening is known as a stoma. A stoma usually protrudes above the skin surface, appearing pink or red, moist, and round, and it lacks nerve sensations.
There are different types of ostomies, including colostomies, ileostomies, and urostomies:
