Q: What about the bladder? Pregnant women tend to have a more frequent urination. Is that the same with a corset? --- Sandra  (7/2/14)

A: The actual increase in abdominal pressure in the bladder is relatively small. The musculature, such as diaphragm and the pelvic floor, stretch or expand to accommodate excessive pressure. Pressure differences from straining or during lifting can be considerably greater. 


Frequent urination from bladder compression is not necessarily related to corset-wearing. The focus of the compression in lacing is different from that of pregnancy, due to the limited space in the lower pelvis to accommodate the growing uterus and the clamping of the bladder laterally between the pubic bone and the uterus. In corseting, this is not the case, with the pressure focus being at some distance from the bladder.
