Raynaud's is a fairly rare disorder of the blood vessels supplying the skin. During a Raynaud's attack, the blood vessels narrow, limiting blood circulation to affected areas. It makes parts of your body (usually fingers, toes, nose and ears) feel numb and cool in cold temperatures or under stress.
PPROM is associated with 30-40% of preterm deliveries and is the leading identifiable cause of preterm delivery. PPROM complicates 3% of all pregnancies and occurs in approximately 150,000 pregnancies yearly in the United States.
A large uterus or a short cervix can cause you to go into labor early. A chronic illness , such as high blood pressure, diabetes, or obesity, can cause early labor. An infection , such as a urinary tract infection or vaginal infection, can weaken the membranes (linings) of the amniotic sac around your baby. This could lead to premature rupture of the membranes and preterm labor. Problems with the placenta , such as placenta previa or placental separation, may cause preterm labor.
