What Causes Low Lying Placenta During Pregnancy?

Posted on Fri, 14 Aug 2015

Question: What is low lying placenta? I am 35 weeks due. I have been told that it's 2cm away from OS.

Answered by Dr. Nidhi Setia (2 hours later)

Brief Answer:
placenta is close to cervix.

Detailed Answer:
Hello
Welcome to HCM.
I Understand your concerns.

Low lying placenta means the placenta has implanted low down in your uterus, close to your cervix.

Placenta 2cm away from OS at 35 weeks may be an indication for caesarean section. But the judgement varies from doctor to doctor.

It is important to monitor the progress your pregnancy thoroughly.

Can you please upload your scan report?

Take care.
Thanks.

Thanks for the reply. I don't have any report with me. They wont give in hand. My concern is at what time I mean in which week they plan to do c- section and for normal vaginal birth how much cm away it should be...in my last Thursday scan they said anterior dipping into.lower segment...could you please answer this...

Brief Answer:
normal is atleast 5cm away from OS.

Detailed Answer:
You are most welcome.

Normally, placenta should be atleast 5cm away from the OS for safe vaginal delivery.

Sometimes, there is vaginal bleeding due to low lying placenta. This is one immediate indication for C-Section. Otherwise, it is done when your pain starts or whenever is the due date (whichever is earlier).

Your scan report means that placenta is on anterior wall of uterus on its lower segment.

Please avoid heavy weight lifting and strenuous exercises.

Keep in touch with your doctor.

Hope you have a healthy delivery and baby.
Thanks.

Thanks a.lot.
My last query is, is there any chance of going up even after 35 weeks?
I checked with doc and I was told that no need of complete bed rest..just avoid lifting of heavy items...
Will they plan for c even if normal labor starts?

Answered by Dr. Nidhi Setia (3 hours later)

Brief Answer:
no need of complete bed rrst.

Detailed Answer:
There is no chances of going up after 30 weeks.

Though there is no need for complete bed rest in low lying placenta(grade 1 placenta previa),you should be careful.

If there is any bleeding or pain abdomen .report immediately to your doctor.

Grade 1placenta previa is not direct indication for c-section.it completely depends on progression of labour and doctor too.

Hope it helps.

Feel free to ask further.

Thanks
