What causes premature rupture of membranes?
PROM's causes aren't thoroughly understood, but taking certain steps may help reduce your risk. Smoking increases the risk of PROM, so quit now. Get early, regular prenatal care so that certain complications of pregnancy that increase the risk of PROM, such as uncontrolled high blood pressure, can be detected and treated. You also are at increased risk of PROM if you are pregnant with twins (or a higher number of multiples).
