Miscarriage may lead to post-traumatic stress disorder: Study

Updated: Nov 02, 2016 13:04 IST

Washington D.C. [USA], Nov. 2 (ANI): A new study says that women, following a miscarriage or ectopic pregnancy, might undergo post-traumatic stress disorder.

The team behind the research from Imperial College, London stated that the findings suggest women should be routinely screened for the condition, and receive specific psychological support following pregnancy loss.

In the study the team surveyed 113 women who had recently experienced a miscarriage or ectopic pregnancy.

The majority of the women in the study had suffered a miscarriage in the first three months of pregnancy, while around 20 percent had suffered an ectopic pregnancy, where the baby starts to grow outside of the womb.

The results revealed four in ten women reported symptoms of post-traumatic stress disorder (PTSD) three months after the pregnancy loss.

Miscarriage affects one in four pregnancies in the United Kingdom and is defined as the loss of a baby before 24 weeks, although most miscarriages occur before 12 weeks.

Ectopic pregnancies are much rare, affecting around one in 90 pregnancies. The fertilised egg usually implants in the fallopian tubes connected to the womb, where it cannot grow, and so the pregnancy either miscarries or must be ended surgically or with mmedicine.

In the new study, funded by the Imperial College Healthcare Charity, the scientists sent the women questionnaires asking them about their thoughts and feelings after their pregnancy loss. All of the women had attended the Early Pregnancy Assessment Unit at Queen Charlotte's and Chelsea hospital, West London.

The results revealed that three months after the pregnancy loss, nearly four in ten women (38 percent) met criteria for probable PTSD.

Among the women who suffered a miscarriage, 45 percent reported PTSD symptoms at this time, compared to 18 percent of the women who suffered an ectopic pregnancy.

Post-traumatic stress disorder is caused by stressful, frightening or distressing events, and causes people to relive the event though nightmares, flashbacks, or intrusive thoughts or images that appear at unwanted moments. The symptoms can start weeks, months or even years after a traumatic event and can cause sleeping problems, anger, and depression.

The women in the study who met the criteria for PTSD reported regularly re-experiencing the feelings associated with the pregnancy loss, and suffering intrusive or unwanted thoughts about their miscarriage. Some women also reported having nightmares or flashbacks, while others avoided anything that may remind them of their loss, or friends and family who are pregnant.

Furthermore, nearly a third said their symptoms had impacted on their work life, and around 40 percent reported their relationships with friends and family had been affected.

Jessica Farren, lead author of the research, from the Department of Surgery and Cancer at Imperial, said that this research suggests women should have an opportunity to discuss their emotions with a medical professional.

"We were surprised at the high number of women who experienced symptoms of PTSD after early pregnancy loss. At the moment there is no routine follow-up appointment for women who have suffered a miscarriage or ectopic pregnancy. We have checks in place for postnatal depression, but we don't have anything in place for the trauma and depression following pregnancy loss," stated Farren.

"Yet the symptoms that may be triggered can have a profound effect on all aspects of a woman's everyday life, from her work to her relationships with friends and family," she added.

Dr Farren further explained that previous research has suggested women who experience a stillbirth may develop post-traumatic stress disorder. However this is the first research to only focus on early pregnancy loss.

"There is an assumption in our society that you don't tell anyone you are pregnant until after 12 weeks. But this also means that if couples experience a miscarriage in this time, they don't tell people. This may result in the profound psychological effects of early pregnancy

loss being brushed under the carpet, and not openly discussed," she said.

The team, who conducted their research in collaboration with the University of Leuven in Belgium, also questioned a control group of 50 women with ongoing pregnancies.

The study results also revealed around one in five women had symptoms of moderate anxiety at three months after their pregnancy loss. In the control group, one in ten reported symptoms of anxiety.

Furthermore, one in 20 women reported symptoms of depression three months after their loss.

Tom Bourne, senior author of the study, said the team are now planning larger follow-up studies, to confirm the findings and help identify at-risk women.

"Not all women who suffer a miscarriage or an ectopic pregnancy will go on to develop PTSD or anxiety and depression. Therefore we are now investigating why some women may be more at risk than others, to help medical professionals identify who may need extra support," said Bourne.

Jane Brewin, who part-funded the research, said, "This study gives a voice to many women who have suffered miscarriage in silence and the often significant consequences that follow. The message is clear: in a civilised society it is not acceptable for women to suffer in this way. Following this study there must now be added impetus to change miscarriage treatment and care; many women need more support following a miscarriage and the NHS needs to rethink how women are treated throughout the experience so they do not suffer from PTSD and other psychological impacts. Tommy's Centre for Early Miscarriage Research was opened this year with the support of many families who want to bring about change and we'd encourage all families to join with us to find answers to miscarriage and help improve care for everyone."

Bourne added that in addition to improving diagnosis of psychological disorders following miscarriage, researchers need to assess what treatments may help.

"We know that talking therapies, such as cognitive behavioural therapy, have been successful at treating PTSD. However we need to investigate how this treatment should be tailored to women who have suffered an early pregnancy loss," stated Bourne.

Ian Lush, who funded the study, said, "Clearly, losing a baby at any stage is devastating for parents. We recognised early on the potential this piece of research had, and equally, how important the findings would be to patients and clinical staff right across the NHS. The outcomes that are being shared will hopefully mean the effects of early pregnancy loss deservedly get the spotlight shone on them, and women and their partners, thanks to better understanding of those effects, get the extra support they need."
