[[Calciuria and phosphaturia during fasting. Effect of calcitonin alone or with a thyroid hormonotherapy combination]

The author compares 4 groups of obese individuals subjected to fasting for 7 days: Some took no medication, the others received either triiodothyronine (100 to 150 microgram per day), or calcitonin (1 unit MRC per day) or both triiodothyronine and calcitonin. An increase in calciuria and phosphaturia was observed with either triiodothyronine or calcitonin. Triiodothyronine in association with calcitonin did not increase further the calciuria caused by calcitonin but increased phosphaturia. The author offers an explanation for these various observations.
