Placenta previa is a condition in which the placenta is positioned low in the uterus, partially or fully covering the cervix. This can lead to complications as the cervix dilates during labor, potentially causing the placenta to detach from the uterine wall.
How Common Is Placenta Previa?
Approximately 1 in 200 pregnant women experience placenta previa during the third trimester. The condition is more prevalent among women who have:
- Given birth to multiple children
- Had a cesarean section
- Underwent surgery on the uterus
- Carried twins or triplets
Types of Placenta Previa
- Complete Previa: The cervical opening is entirely obstructed by the placenta.
- Partial Previa: A section of the cervix is covered by the placenta.
- Marginal Previa: The placenta extends to the edge of the cervix.
Symptoms of Placenta Previa
The signs and symptoms can differ, but the primary indicator is typically painless bleeding during the third trimester. Other symptoms may include:
- Premature contractions
- The baby being in a breech or transverse position
- The uterus measuring larger than expected for the gestational age
Treatment Options
Upon diagnosis, treatment generally involves bed rest for the mother and regular hospital visits. Depending on how far along the pregnancy is, steroids may be administered to help mature the baby’s lungs. If there is uncontrollable bleeding, a cesarean delivery is usually performed, regardless of the gestational age. Some cases of marginal previa may allow for vaginal delivery, while complete and partial previas will necessitate a cesarean section.
Physicians often advise limiting certain activities:
- Refrain from intercourse
- Minimize travel
- Avoid pelvic examinations
Causes of Placenta Previa
The exact cause remains unclear, but several factors can increase the risk of developing placenta previa, including:
- Being over the age of 35
- Having had more than four pregnancies
- A history of uterine surgeries, regardless of the incision type
Coping with Placenta Previa
Receiving a diagnosis of placenta previa can be both shocking and frustrating, especially with the anticipation of a healthy delivery. Support groups exist for mothers on bed rest and those experiencing placenta previa, which can provide much-needed assistance during this challenging time. Healthcare providers, such as doctors and midwives, can help connect you with these support networks.
