Does a catheter make bladder shrink?

Yes, a catheter can make the bladder shrink. When a catheter is inserted into the bladder, it can cause the bladder to become irritated and inflamed. This inflammation can lead to scarring and contraction of the bladder, which can make it smaller and less able to hold urine. Additionally, the presence of a catheter can interfere with the normal functioning of the bladder, which can also lead to shrinkage.
