Placenta previa is a condition that can affect pregnant women. In this condition, the placenta covers part or all of the cervix. Because the placenta is vital for your baby’s growth, placenta previa can be serious. Early diagnosis and proper care help keep both mother and baby safe. In this blog, we will explain placenta previa, its causes, symptoms, diagnosis, and treatment options. We will also share tips for expectant mothers and answer common questions.
What Is Placenta Previa?
Placenta previa happens when the placenta sits low in the uterus and covers the cervix. The cervix is the opening to the birth canal. Normally, the placenta attaches higher up in the uterus. However, with placenta previa, it blocks the baby’s way out. This can cause bleeding and other problems during pregnancy and delivery.
Causes and Risk Factors
Several factors can increase the risk of placenta previa. While the exact cause is often unknown, some women are more likely to develop this condition. Common causes and risk factors include:Having had placenta previa in a previous pregnancyCarrying more than one baby (twins or triplets)Previous surgery on the uterus, such as a C-sectionBeing over 35 years oldSmoking during pregnancyHaving a large placentaHistory of miscarriages or abortions
Symptoms of Placenta Previa
Placenta previa often causes painless bleeding during the second or third trimester. However, not all women have symptoms. Common signs include:Bright red vaginal bleeding, often without painBleeding after sexual activityBleeding that starts and stops on its ownRarely, mild cramps or contractions
Sometimes, there are no symptoms until a routine ultrasound finds the problem.
How Is Placenta Previa Diagnosed?
Doctors usually diagnose placenta previa with an ultrasound. This test uses sound waves to create pictures of your uterus and baby. Sometimes, a transvaginal ultrasound gives a clearer view. If you have bleeding, your doctor may also check your vital signs and do blood tests. Early diagnosis helps plan safe care for you and your baby.
Treatment Options for Placenta Previa
Treatment depends on how far along you are and how much bleeding you have. In many cases, doctors recommend:Resting and avoiding heavy activityAvoiding sex or anything that could trigger bleedingStaying in the hospital if bleeding is heavyMonitoring your baby’s growth with regular ultrasounds
If the placenta still covers the cervix close to delivery, a C-section is usually needed. Most women with placenta previa deliver healthy babies with proper care.
