Women with Crohn’s disease often have concerns about how the condition might affect their ability to have children and experience a healthy pregnancy. Successful pregnancies are possible for many. With proper planning and consistent medical care, women with Crohn’s can navigate pregnancy with positive outcomes for themselves and their babies.
Fertility and Conception
The ability to conceive for women with Crohn’s disease is comparable to those without the condition, especially when the disease is in remission. Active inflammation, however, can reduce fertility. For instance, severe inflammation in the small intestine can affect the fallopian tubes, and active Crohn’s disease has been linked to a potential decrease in ovarian reserve.
Certain surgical procedures, such as ileal pouch-anal anastomosis (IPAA), can also impact fertility due to scarring around the fallopian tubes and ovaries. Despite these considerations, conception is achievable. Healthcare providers emphasize pre-conception counseling to discuss family planning and optimize disease control before attempting pregnancy.
Managing Crohn’s During Pregnancy
Maintaining remission of Crohn’s disease before and throughout pregnancy is important for both the mother and the developing baby. Active disease during pregnancy significantly increases the risk of complications. Continuous and collaborative medical care involving a gastroenterologist and an obstetrician is essential.
Most Crohn’s medications are safe to continue during pregnancy, and stopping them can be more detrimental than continuing treatment. Medications such as aminosalicylates, corticosteroids, and immunomodulators are safe. Biologic therapies, including anti-TNF agents, are also safe and should be continued, often throughout the third trimester, as the benefits of disease control outweigh potential risks. Certain medications like methotrexate should be discontinued well before conception due to risks of birth defects or miscarriage.
Close monitoring throughout pregnancy includes regular check-ups and nutritional support. Women with Crohn’s may have increased needs for certain nutrients due to malabsorption or inflammation. Folic acid supplementation is important, with higher doses recommended for those taking certain medications or with specific disease locations. Iron and vitamin D supplementation may also be necessary. Should a flare-up occur during pregnancy, it will be managed promptly to minimize risks, often by adjusting medication in consultation with the healthcare team.
Potential Outcomes for Mother and Baby
While most pregnancies in women with Crohn’s disease are successful, awareness of potential outcomes is important. If the disease is active during pregnancy, there can be an increased risk for the mother of complications such as pre-eclampsia and gestational diabetes. The risk of blood clots, including deep vein thrombosis, is also higher, particularly during flare-ups.
For the baby, active maternal Crohn’s disease can increase the likelihood of preterm birth or low birth weight. However, Crohn’s disease itself does not increase the risk of major birth defects. There is a slightly increased genetic predisposition for the child to develop inflammatory bowel disease, but this is not a certainty. The condition does not impact the baby’s cognitive development.
Delivery and Postpartum Considerations
Decisions regarding the mode of delivery are individualized and depend on several factors. Vaginal delivery is possible and preferred for women with Crohn’s disease. However, a Cesarean section may be recommended for those with active perianal Crohn’s disease or a history of specific surgeries like IPAA to prevent complications such as anal sphincter injury. Studies suggest that the mode of delivery does not impact the mother’s Crohn’s disease activity.
The postpartum period carries a risk of disease flare-ups, with approximately 30-35% of women with Crohn’s experiencing a flare after childbirth. This risk can be higher if the disease was active during the third trimester or if medication therapy was de-escalated. Continued monitoring and adherence to medication are important in the months following delivery. Most Crohn’s medications are safe during breastfeeding, allowing mothers to nourish their infants while maintaining their disease control.
