Information about placental abruption

The placenta is your baby’s support system in the womb. If your placenta doesn’t work properly, your baby is at risk of health problems. Placental abruption is when your placenta comes away from the wall of your womb.

plancental abruption diagram

The placenta processes your baby’s nutrients, waste and oxygen by bridging your baby’s blood circulation with that of your own. It sits inside the womb alongside your baby, and is attached to the wall of the womb. It is linked to the baby by umbilical cord, which is attached to the baby’s abdomen.

Placental abruption (discussed here) and low-lying placenta are conditions linked to the placenta that can cause premature birth.

Placental abruption is a serious condition in which the placenta starts to come away from the inside of the womb wall before the baby has delivered. This is an emergency because it means that the support system for the baby is failing.

Studies show that placental abruption affects up to 1% of pregnancies (though it is suspected that the actual figure may be higher as it may not always be diagnosed). In this condition some or all of the placenta separates from the wall of the womb before the baby is delivered. This can be caused by an impact such as a car crash, or may be related to a condition such as pre-eclampsia or fetal growth restriction, also know n as Intrauterine growth restriction or IUGR.

When placenta abruption happens the placenta is damaged and the baby may not be supported to develop properly.

Symptoms of placental abruption

  • pain in the back and abdomen
  • contractions
  • tender womb
  • vaginal bleeding.

If you are suffering from any of the symptoms above get medical help immediately because they may signify an emergency.

In most cases of placental abruption it will be diagnosed from obvious blood loss.

However it could also be a concealed or ‘silent’ abruption, in which the blood is trapped between the wall of the womb and the placenta so there is little or no bleeding. In this case it would be diagnosed when the woman reports pain in the back or abdomen.

The level of pain depends on the severity of the abruption. A less severe abruption may feel like a bruise. A severe abruption will be very painful.

Risk factors for placental abruption

Placental adruption is more likely if the mother:

  • had a previous placental abruption
  • is a smoker
  • is a cocaine or amphetamine user
  • has chronic high blood pressure
  • has pre-eclampsia
  • has had a blow to the stomach or an indirect trauma that may have affected the placenta
  • has an intrauterine infection.

To reduce your risk avoid smoking in pregnancy and taking street drugs in pregnancy.

What does placental abruption mean for me and my baby?

The effects and treatment of placental abruption depend on how severe it is. If you are under 34 weeks and only a small part of the placenta has broken away from the womb you will be monitored closely to make sure the baby is growing properly and to watch for signs of labour starting.

If there is a risk of your baby not growing properly then labour may be induced.

If the abruption is more severe, you are losing lots of blood and the baby is in distress or at risk of not growing properly you may need to have your labour induced or have an emergency caesarean.

In addition to any problems that the baby may have from the placental abruption, there are health risks of being delivered early. These depend on how far into the pregnancy you are.

    I lost my little boy at ten days over his due date I was sent into the hospital on the Tuesday they said I I high blood pressure but sent me home and said they would induce me on Thursday
    They induced me on Thursday everything was fine baby heart beat was good he was fine I went for a walk had something to eat I came back because I had bad back pain and my contractions had start which were quit bad my midwife put me on the monitor and was a bit worried with how strong my my contractions were she then got another midwife to check it she said to take me of the monitor and that everything was fine with baby I then asked for pain relie pethidine which made me sleepy I then feel asleep and about 2:00 Friday morning my waters had broken there was a bit of blood but I though that can happen when your water break the midwife came in and said I was in labour they kept trying to find a heart beat but in the end there was no heart beat
    Could this be a placenta abruption and could I happen again in another pregnancy do women have more children after something this happens

  • By Midwife @Tommys on 21 May 2018 - 16:27

    Charlotte, I am so sorry to hear this. It is so devastating. Usually abruption is associated with continual pain. While contraction pains come and go, there is no break from the pain with abruption. I can't rule this out but there may be other reasons why your baby died. Have you had a discussion with your obstetrician to discuss the reasons? An appointment to talk through your pregnancy and the care received should be arranged for you. This should include discussing any future pregnancy and what should be put in place to reduce your risks. You are also very welcome to call us here at Tommy's if you want to discuss anything with a midwife. 0800 0147 800. We hope you have good support from your family and friends and we send best wishes from all at Tommy's.

    I had a Placenta Detached at 39weeks and i had to go for a C-section, i had abdominal pain and then mild bleeding .
    My son is 3yrs old and diaglonised with ASD, is placenta detachment a problem.
    I remember the doc telling me that the heart beat of the baby was monitored and it was 150.
    Requesting for advice and feedback

  • By Midwife @Tommys on 15 May 2018 - 15:03

    Hi LD
    thanks for getting in touch. The person best placed to go through your medical and obstetric history with you about you and your son, is your GP. They will have access to your full medical and obstetric records and be able to more accurately help you to make any conclusions from there. I do hope that you get the answers you need soon.
    I am sorry to not be able to help you very much, but this is really not within a midwives knowledge base.
    All the best
    Sophie, Tommy's Midwife

    I had a placenta abruption at 39 weeks and lost my baby. until the midwifes realized what happened it was too late. Then by the next pregnancy i had a placenta abruption again at 36 weeks and luckily they manged to save my daughter who was born healthy and is now 5 years old. If i become pregnant again will i get another placenta abruption? and will it happen earlier than 36 weeks??

  • By Midwife @Tommys on 9 May 2018 - 11:10

    Dear Sara,
    I am so sorry to hear that you had a placental abruption and your firstborn died as a result of this. You then went on to have another baby at 36 weeks born early because of another abruption.
    I have included a link which states that the chance of abruption after 2 previous pregnancies complicated by abruptions is 19-25%.
    https://www.rcog.org.uk/en/guidelines-research-services/guidelines/placental-abruption---query-bank/
    If you feel able to become pregnant again you will be monitored extremely closely and this care will increase at around 34 weeks. It will mean that you will also be very aware of any signs or symptoms of abruption as your pregnancy progresses and you would seek medical help immediately.
    Please keep in contact and call us on 0800 0147 800 if you need any support.
    Warmest wishes

    I had placenta abruption at 36 weeks with my son. He was born via emergency c section and I now a healthy beautiful 3 year old boy. I'm terrified if I got pregnant this could happen again x

  • By Midwife @Tommys on 3 May 2018 - 12:59

    Hi Leanne, Thank you for your comment.

    We can understand your anxieties regarding a future pregnancy. Placental abruption can be very unpredictable but as you have had one before, then you will be closely monitored and should be under consultant led care. It may be worth speaking to your GP to see if you can have a pre conception meeting with one of the consultants at the hospital who will be able to pull your notes and you can discuss anything that is worrying you. Hope this helps, take care, Tommy's Midwives x

    Hi,I recently lost my beautiful baby girl this month on the 16 of this month ,at the hospital they had already booked me an elective c section but I did not reach the day,early in the morning I felt back pain ,I woke up and I noticed that im bleeding it was a severe bleeding,I developed bp in pregnancy I didn't know about and the clinic I was going to did not catch it early,but I did get the treatment I don't know if it's was too late for me to take medication for bp,there was protein in my urine also every antenatal visit I had just that no one explain the danger and me I had no idea that my life was in danger and my child's too,so I bleed a lot when I got to hospital it was too late for my baby died a stillbirth

  • By Midwife @Tommys on 26 Apr 2018 - 14:50

If we can offer you any support or guidance or you would just like someone to talk to then please email us if and when you are ready on [email protected] Please take care and be kind to yourself in these early days. Best Wishes Tommy's Midwives x

    I’m so very sorry about your Babygirl. I’m also suffering from the loss of my Babyboy on April 17, 2018 the same way. Mine was “silent” because the blood was trapped behind my placenta. I felt as if I had to reply to you, because I noticed the similarities between us. I believe the clinic I attended for all of my pre natal care did not monitor me close enough being that my pressure was often high, & the amount of swelling I had.

  • By Midwife @Tommys on 9 May 2018 - 16:02

    Dear Auja,
    I am terribly sorry to hear that you lost your BabyBoy in April if there is anything that you want to talk about you can email us at [email protected] or call 0800 0147 800.

    Hi
    I had my daughter 9 months ago during my labour I started bleeding and it got heavier and heavier so they induced me. My daughter was not distressed, but was a lot of blood at delivery. My daughter was born with a serious eye infection, not sure why. I wanted to find out the effects to the body after this because all though they did not say my placenta was ruptured they said it could be coming away. Ever since I've had my baby I have serious painful stomach cramps especially if i exercise and if my baby stands on my stomach. It's never happened with my son and I'm not sure what is going on and I've asked my gp and they cannot give me answer. It's just very uncomfortable and can last a few hours like sharp pains in my lower abdominal and feels aggregated by standing up and sitting down after lower body exercise. Would love some help with this.

  • By Midwife @Tommys on 4 Apr 2018 - 10:18

    Hi Lee
    I am sorry to hear that you have been experiencing some pain and discomfort since the birth of your daughter 9 months ago. A placental abruption is a worry whilst you are still pregnant and in labour. But once both baby and placenta are safely out of the uterus, it will not cause any further problems for you. I would advise that potentially you see a different GP in your surgery for a second opinion. It sounds more like it could be a muscular problem affecting your stomach muscles and uterine muscles after the pressure of pregnancy and childbirth rather than anything worrying. The GP may be able to refer you to a Physiotherapist if they feel that this would be of use.
    Please do call or email if you need any further advice or support.
    All the best
    Sophie,Tommy's Midwife :)

  • By Kate (not verified) on 20 Mar 2018 - 07:36

    I had a full placental abruption at 36 weeks with my little girl, she was breech and I was in labour. I had previously had a c section and my wound ruptured too, luckily we are both fine and she is now 4 and absolutely perfectly healthy. I am healthy and non smoker etc just wondering what the risk factors are to have another baby? Would this happen again?

  • By Midwife @Tommys on 21 Mar 2018 - 11:59

    Hi Kate,
    There would be a risk of this happening again but this risk depends on your health in pregnancy and lifestyle factors too. Did you have a de-brief following the birth of your little girl? You should have been offered the opportunity to go through what happened and any possible reason for the cause (although there may not be an obvious answer), if this has not happened you can ring the hospital and they can arrange this for you and discuss about planning for another pregnancy. It is likely that they would suggest that you have an elective c section if you do have another pregnancy. If you would like to talk about this in more detail then please do email us [email protected]
    Best wishes, Tommy's midwife.

    My granddaughter just had a beautiful baby boy after an emergency c section because the placenta had detached and the baby's heart rate dropped. He was born 6lbs 8 oz on the 37 or 38 week. They rushed him to neonatal and then took him to another neonatal specialty hosp to check for neurological damage. He was pink and not on oxygen when they took him to the other hosp. She hasn't even had the chance to hold him yet. My heart is broken for her and the baby. I pray they will be ok. I found your story as a glimmer of hope that he will be ok. I am not near her vicinity and am worried sick for them! Thank you for sharing your story.

  • By Midwife @Tommys on 28 Mar 2018 - 09:59

    Hi Tina, I am really glad that you have found our story helpful. I am not able to make comment on your great grandson's condition except to say that some hospitals are better equipped than others and I am sure that he has been taken to the safest place and that he is being very well cared for.
    Take care and please let us know how he gets on. Best wishes

  • By Kate (not verified) on 30 Mar 2018 - 15:44

    I hope they have a speedy recovery ❤️ Lots of love and best wishes!
    At the time of mine I never realised the seriousness of it but looking back now it is so scary to think what the outcome could of been. The professionals are amazing at what they do and I’m sure he is recieving the most amazing special care. All the best. Hope she gets to have a cuddle soon.
    Best wishes

    I was 23weeks and 3days when I found out that my placenta pulled away from my womb. 1 week before I had some pain I went to my doctor midwife and she said everything was fine since there was no blood. The pain had stopped. The following Monday morning I woke up to blood. To make a long story short my water broke and the next day I went in to labor. My daughter's heart stopped beating before the labor started. I was a smoker of cigarettes. Since I have stopped smoking them if I got pregnant again would this happen again. I also have high blood pressure. I'm afraid to try again and some days I just want to go be with her. Looking for answers

  • By Midwife @Tommys on 5 Mar 2018 - 13:27

    Hi,
    I am so sorry about the loss of your daughter and what you have been through. It is completely understandable that you are looking for answers and wanting to understand what happened. Has any de-briefed you following the loss of your daughter and given you the opportunity to go through what happened? If not then you can contact the maternity unit and ask how to arrange this. It is great that you have given up smoking for this pregnancy as this will really help for you to have a healthy pregnancy. The team will also monitor your blood pressure closely and try to control this as much as possible. If you have any concerns or notice anything has changed then please do contact your midwife for support. Best wishes, Tommy's midwives.

    Im 20 years old, my pregnancy was perfect i had no problems with bloodpressure, when i vistited the midwife everything was perfect on the growth chart. Untill one morning i woke with severe abdominal pain after being rushed to hospital i found out my baby boy no longer had a heartbeat. It was all internal bleeding i had a full placental abrution after battling pain i eventually had an emergency c section i lost 3 ltrs of blood and had multiple blood transfusions, I know im lucky to be alive but i just want an answer the more im reading the more it makes no sense whats happened . I dont smoke or drink im healthy and the placenta sheered off the wall completely when i was asleep in bed. Will this happen again in another pregnancy? And why has this happened?

  • By Midwife @Tommys on 10 Jan 2018 - 11:32

    Hi there. I am ever so sorry about the passing of your son after your placental abruption. I can only begin to imagine how difficult this has been for you and your family. You should have a de-briefing appointment with an obstetric consultant at your maternity unit reviewing your notes and your medical history in order t0 try and break down a little more why this might have happened and how you would be cared for in a future pregnancy. If this appointment has not happened yet, you can call your antenatal clinic in the hospital, or any midwife contact that you have, to try to help arrange one for you for asap. This will also be a huge part of your grieving process. I know this is a very difficult time and so you need lots of support and advice throughout the next few months
    Please do feel free to call me on 0800 0147800 if you wish to have a friendly chat about how you are feeling and how you may be able to access more support locally in coping with your grief.
    The link below to our webpage on placental abruption gives you lots more information about what the possible causes of this are. Sometimes, though, no direct cause can be found for this occurring. I do hope that this helps.

    I woke one morning with severe stomach pains and then sudden blood loss, was rushed to hospital on blue lights and monitored for 14 hours before being induced. My sons heart rate was brilliant throughout and we’re fortunately home and well.
    I lost over 400ml (the only started weighing the pads 8 hours after being admitted) and I’ve recieved no answer as to what actually happened? I’m extremely healthy, did pregnancy yoga and felt really fit and well throughout my pregnancy. When I got pregnant I only weighed 6stone7 so I’m not sure if my size has some connection? He was breech for a few weeks and a couple of days before I had him I felt him turn, I also felt light headed the day before I had him and wondered if I’d lost my plug as my discharge suddenly increased. Always wanted more than one child but now I’m petrified that il have a 2nd child even early and that we both might not be as lucky! Does this sound as though it’s a placental abruption?

  • By Midwife @Tommys on 3 Jan 2018 - 10:47

    Hi Alice. It is very difficult to know without looking at your notes/through your history. Please make a consultant midwife/obstetrician appointment at your hospital where you had the baby to have a de-briefing session- where they go through your notes and try to understand what may have caused this experience. Sometimes a conclusion can be drawn, other times it is not possible! I hope that this is useful but am also very pleased that you had happy outcome!

    Currently in hospital (35weeeks +3days, baby number 1). Has quite severe blood loss 2days ago which has now settled, was having lots of contractions but now settling. Didn’t have any pain or warning signs. No risk factors or trauma. The doctors are planning to send me home soon but this idea terrifies me as I’m obviously v high risk for having further placental abruption and I’ve read that in 20% of cases there is no bleeding - so if this were to happen at home I would have no way of knowing and she would probably be stillbirth? I’m not sure if I’m overreacting or if there is any situation I should be pushing for? Or some questions I should be asking to reassure myself? I’m happy to sit in hospital for as long as needed on a monitor but I’m don’t think that’s going to happen!

  • By Midwife @Tommys on 30 Oct 2017 - 13:59

    Hi. I would suggest that you talk to the doctors about your concerns and ask them to explain the risks to you. Have they diagnosed placental abruption or could this be antepartum haemorrhage with unknown cause? If the CTG is normal then home may be your best option but I am reluctant to advise without access to all the test results. Wish you all the best from Tommy's midwives

    Two daughters one at 29 weeks (has some learning delays she is 12) my other daughter 36 and 5. Two days from being "full term" I am not a smoker I'm not a cocaine or amphetamine user. I was pretty healthy and active during both pregnancies. According to testing my placenta I was 99% abrupted. They lost the fetal heart rate so while I had entered the OR as delivering awake soon it became emergent. My question is this is there any correlation between the placenta detaching for an undetermined amount time and any cognitive delays or is it simply due to the complications of being 2.5 pounds. This is a question I have been wondering for years and would love to finally get some answers. I know how blessed I am that she survived and she's amazing but the massive difference between my girls the other has been identified as gifted both times I abrupted. Also are there any genetic reasons that this may happen?

    Thank you.

  • By Midwife @Tommys on 9 Oct 2017 - 16:00

    Any abruption is a serious emergency as I am sure you realise having had 2 daughters affected. If the fetal heart rate slowed this could suggest that there was some degree of oxygen deficiency to the baby which may account for cognitive delays she has experienced. Unfortunately although you have identified some high risk factors this could in fact happen to anyone. Best wishes to you and your daughters x

  • By Anonymous (not verified) on 28 Sep 2017 - 21:14

    Is it considered a placental abruption before 20 weeks? My OB only stated that my placenta tore away from the uterine wall (13 weeks along). In this case is it considered a subchorionic hemorrhage?

  • By Midwife @Tommys on 29 Sep 2017 - 12:33

    I am so sorry for your loss.
    Yes a placental abruption is considered to be after 20 weeks.
    In your case the type of haemorrhage would need to be confirmed by the scan findings as it depends on the location.

    My abruption was back in 2001 I went into normal labour, no other signs that anything other than a normal labour was taking place. Within 2 hours I had lost all my strength and energy but managed to call my midwife by then it was 1 long continuous contraction no let up just continual pain. My son was born asleep 9 hours later (normal birth)

    I 've had two placental abruptions first ending in still birth second in an emergency c section and premature birth. Other symptoms are light handedness and vomiting. This condition is rarely spoken of and women are not told about it or to watch for the symptoms like other well known complications during pregnancy which i think it should be so they are made aware.

  • By Anonymous (not verified) on 13 Aug 2017 - 03:51

    I also went through placental abruption two years ago which ended in still birth at 37 weeks. I am now expecting baby number two, only a few weeks pregnant and I am terrified.

    This article is extremely useful in outlining the symptoms of abruption, and I feel it should be produced intonleaflets and distributed to all hospitals. I lost my little girl in 2012 to abruption caused by Pre Eclampsia. I went in complaining about horrific pain in the back and abdomen, and what felt like contactions every minute or so.
    I also had high BP and protein and blood in my urine. The hospital told me to stop being "soft" and go home as I was in slow labour and it would get worse. The third day I went in complaining of this pain, they informed me my baby had died at full term.
    They were so uneducated about abruption and Pre Eclampsia. I presented all the symptoms, yet they did nothing.
    Tommys do amazing work and it's thanks to Tommys that I now have 3 beautiful, living children all born high risk at St. Mary's.
