Crohn’s disease is usually diagnosed between the ages of 15 and 25 — the peak in a woman’s fertility.

If you’re of childbearing age and have Crohn’s, you may wonder if pregnancy is an option. Women with Crohn’s are just as likely to get pregnant as those without Crohn’s.

Eat a nutritious, vitamin-rich diet. Folic acid is especially important for pregnant women. It’s the synthetic form of folate, a B-vitamin found naturally in many fruits and vegetables.

Folate helps build DNA and RNA. This makes it crucial for the early rapid cell division phase of pregnancy. It also prevents anemia and protects DNA from mutations that can develop into cancer.

Pregnancy and Crohn’s treatment

Most medications to treat Crohn’s have been proven safe for pregnant women. However, some may cause birth defects. Also, certain medications that control inflammation from Crohn's disease (such as sulfasalazine) can lower folate levels.

Folate deficiency can lead to low birth weight, premature delivery, and can slow a baby’s growth. Folate deficiency can also cause neural tube birth defects. These defects can lead to malformations of the nervous system, such as spina bifida (a spinal disorder) and anencephaly (abnormal brain formation). Talk to your doctor about getting the right dosage of folate.

Women with Crohn’s can have vaginal deliveries. But it they’re experiencing active perianal disease symptoms, a cesarean delivery is recommended.

Cesarean delivery is the best option for women with an ileal pouch-anal anastomosis (J pouch) or bowel resection. It will help decrease future incontinence issues and protect your sphincter functionality.

The genetic factor of Crohn’s

Genetics appear to play a role in developing Crohn’s disease. Ashkenazi Jewish populations are 3 to 8 times more likely than non-Jewish populations to develop Crohn’s. But so far, there is no test that can predict who will get it.

The highest incidences of Crohn’s are reported in Europe, North America, Australia, Japan, and the tip of South America. There are higher incidences of Crohn’s disease in urban populations than in rural populations. This suggests an environmental link.

Cigarette smoking is also connected to Crohn’s flare-ups. Smoking can make the disease worse to the point of needing surgery. Pregnant women with Crohn’s who smoke should quit immediately. This will help with Crohn’s and also to improve the course of the pregnancy.
