According to research published in The Lancet Public Health and carried out by a UK-wide team of researchers and clinicians from multiple universities and NHS trusts, women entering pregnancy with two or more long-term physical or mental health conditions face a 20% higher risk of miscarriage compared to those with no chronic conditions. The study analyzed 2,225,701 pregnancies and birth events recorded between 2000 and 2022 across England, Scotland, Wales, and Northern Ireland.
Pregnancy Risks Tied to Multiple Chronic Health Conditions
The study evaluated a wide range of maternal complications linked to pre-existing health problems.
Furthermore, researchers found that blood clot risks increased significantly. Women with two or more pre-existing conditions had more than double the risk of venous thromboembolism, a potentially serious type of blood clot. Among women with three or more long-term conditions, that risk jumped to more than three-and-a-half times the risk seen in women with no pre-existing conditions.
Impact on Mental Health During Pregnancy
Pre-existing health issues also impacted mental health outcomes during gestation. According to the study findings, women managing multiple chronic conditions faced around four times the risk of antenatal anxiety and depression compared to peers without pre-existing health problems.
Did you know? Living with several chronic conditions can be physically and emotionally demanding, and pregnancy introduces additional physiological stressors. Access to targeted mental health support is highlighted by researchers as a crucial component of comprehensive maternity care.
Dr. Kelly-Ann Eastwood, joint senior author, honorary lecturer at Queen’s University Belfast, and consultant obstetrician at St Michael’s Hospital, Bristol NHS Foundation Trust, stated that the results help define the urgent clinical challenges facing both women entering pregnancy with multiple conditions and the clinicians caring for them across the UK. She added that the findings highlight the pressing need to restructure existing maternity services to improve antenatal outcomes.
How Maternity Care Pathways Must Adapt
Current maternity care pathways are largely centered on individual conditions. Researchers point out that these traditional models may not adequately meet the complex needs of women living with multiple long-term physical or mental health conditions. Pre-conception care offers an opportunity to review existing health problems and medications before conception, allowing doctors to adjust treatments and establish monitoring plans.
However, the study authors cautioned that the research was observational and relied on routinely collected health records. This design means certain conditions and outcomes may have been under-recorded, and residual confounding could not be completely excluded. Future work by the research team will examine birth and child outcomes while identifying which specific combinations of conditions carry the highest risks.
Frequently Asked Questions
Does having a pre-existing health condition mean I will experience a miscarriage?
No. The study shows an association between having multiple long-term conditions and an increased risk of miscarriage, but it does not mean every woman with a chronic health condition will experience pregnancy loss. Miscarriage has many possible causes.
What specific conditions were analyzed in the study?
The study focused on women who entered pregnancy with two or more long-term physical or mental health conditions, encompassing a broad range of chronic illnesses rather than focusing on a single diagnosis.
What steps should women take before planning a pregnancy?
