Hi and welcome to HCM Low-lying placenta, or placenta praevia, is a complication of pregnancy where the placenta that feeds the growing baby is attached to the lower part of the womb near to or covering the cervix. There are several types of placenta praevia: 1. A low-lying placenta is near the cervical opening but not covering it. It will often move upward in the uterus as your due date approaches. 2. A partial placenta praevia covers part of the cervical opening . 3. A total placenta praevia covers and blocks the cervical opening. Probably your wife is having third type and it is serious and she has to be carefull The main symptom of placenta praevia, and the greatest risk to you and your baby, is vaginal bleeding. The bleeding that signals placenta praevia may occur at the end of the second trimester or beginning of the third trimester. It may be heavy or light.Bleeding is usually painless Mothers with a placenta praevia are also at increased risk of delivering prematurely, before 37 weeks of pregnancy Treatment part 1.90% of placenta praevias early in pregnancy resolve on their own, early treatment is often not necessary unless there are other complications, but in your wife case active intervention is necessary 2.avoid heavy exercise and sex 3.repeat ultrasounds later in pregnancy to verify the position of the placenta. 4.Bed rest 5.In Most of placenta praevia cases caesarean section may be performed. It is better not to travel and car driving also not indicated. She can take a walk in a mall, but strenuous activity is not good. Regards Dr Santosh
