Can Crohn's disease affect my fertility and pregnancy?

Question

Hello doctor,

I am a 28-year-old woman who has been experiencing stomach cramps, loose stools, and fatigue for the past year. After undergoing several tests, I was diagnosed with Crohn's disease. I am worried because I have read that it can affect fertility and pregnancy. My doctor has suggested starting biologic injections.

Are they safe for women of my age?
Can stress make Crohn's disease worse?
Please explain what long-term management involves and whether surgery may be required at some point.

Kindly advise.

Hello,

Welcome to icliniq.com.

I understand the concern.

Crohn's disease is a chronic inflammatory condition that can affect any part of the digestive tract. However, with modern therapy, most women live full and active lives, including having healthy pregnancies.

Crohn's disease itself does not usually reduce fertility, especially when the disease is well controlled. The key principle is that active inflammation has a greater negative effect on pregnancy outcomes than approved medications.

Most biologic medicines, such as anti–tumor necrosis factor (anti-TNF) agents including Infliximab and Adalimumab, are considered safe for women of childbearing age and during pregnancy when properly monitored. Maintaining remission before conception is the strongest predictor of a healthy pregnancy.

Biologic medicines target specific immune pathways that drive inflammation. They are used to:

Induce remission.
Prevent complications such as strictures and fistulas.
Reduce dependence on corticosteroids such as Prednisolone.

These medicines are generally safe but require screening for infections such as tuberculosis before starting therapy, along with regular monitoring during treatment.

Stress does not cause Crohn disease, but it can worsen symptoms and trigger disease flare-ups through gut–brain interaction pathways.

I would suggest the following long-term management:

Regular follow-up with a gastroenterologist.
Maintenance medication, even when symptoms improve.
Monitoring with blood tests, stool markers, imaging, and sometimes colonoscopy.
Nutritional support, including supplementation of iron, vitamin B12, and vitamin D when needed.

Approximately 30 to 50 percent of patients may require surgery at some point in their lives. However, early treatment with biologic medicines such as Infliximab or Adalimumab significantly reduces the risk of surgery.

I hope you are satisfied with my answer. For further queries, you can consult me at iCliniq.
