Discovering that you're pregnant is a moment filled with joy! If you are living with multiple sclerosis (MS), it can be natural to have questions and concerns about how pregnancy might impact your health and the course of your condition.
The Basics
Let's start with the most important information. There is no evidence that pregnancy speeds up or worsens the effects of MS. There is no evidence that MS causes infertility. And studies have shown there is no difference in pregnancy, delivery, or birth defect rates between women with MS and those without. So at its core, pregnancy with MS is completely viable. That being said, there are some things to be aware of.
Potential Symptoms
Pregnancy can have varying effects on MS symptoms. Some women see a temporary improvement in symptoms, particularly during the second and third trimesters. This may be due to the body's natural anti-inflammatory processes that help suppress the immune system. However, others may find their symptoms worsen, especially during the first trimester.
While the risk of relapse tends to decrease during pregnancy, there is a slight increase in the postpartum period. Monitoring symptoms closely, staying in regular contact with your healthcare team, and having a plan in place for postpartum care are essential for minimizing any potential relapse impact. Your neurologist may recommend a personalized approach, considering factors such as breastfeeding and the resumption of disease-modifying therapies (DMTs) post-delivery.
During birth, women with MS are more likely than other women to experience a few differences. The baby may be smaller than normal (but still healthy!) based on the time they've spent in the womb. Because MS affects muscles and nerves, it may also be more difficult to push the baby out during birth. Similarly, because of muscle problems from MS cesarean births are more common.
Managing Medications
No DMTs are approved by the FDA for use during pregnancy. It's crucial to discuss the safety of these medications during pregnancy with your neurologist. Balancing the management of MS symptoms with the well-being of the baby requires careful consideration and open communication with your healthcare providers.
Similarly, most medications used to treat MS symptoms are not safe to use during pregnancy. For delivery, all forms of anesthesia are considered safe, but working closely with your provider is important for all medicines being considered.

Health and Wellness
Adopting a healthy lifestyle is beneficial for all pregnant women, but it's particularly important for those with MS. This includes a well-balanced diet, regular exercise, and adequate sleep. These lifestyle factors contribute to your overall well-being and may positively impact your MS symptoms. Moreover, proper nutrition is essential for fetal development. Exercises like swimming or prenatal yoga can help maintain physical fitness without causing strain on the joints.
Pregnancy can bring about a range of emotions, and it's important to prioritize your mental health. Living with a chronic condition like MS may add an extra layer of complexity. Seek support from friends, family, and mental health professionals who can provide guidance and assistance in managing both the physical and emotional aspects of pregnancy with MS. Joining support groups or connecting with other mothers who have navigated pregnancy with MS can provide valuable insights and emotional support.
The Importance of Support
It is crucial to talk to your neurologist about your pregnancy as soon as possible. They can look at your current MS treatment plan and make necessary adjustments to ensure the well-being of both you and your baby. As mentioned above, some medications used to manage MS may need to be adjusted during pregnancy to minimize potential risks. Additionally, your neurologist can provide guidance on the potential impact of hormonal changes during pregnancy.
Regular prenatal check-ups are vital for any pregnant woman, but they take on added significance for those with MS. Monitoring your overall health, as well as your MS symptoms, allows healthcare professionals to address any concerns promptly. Open communication with your obstetrician and neurologist ensures a coordinated approach to your care. Routine monitoring may include neurological examinations, imaging studies, and assessments of vitamin D levels, as vitamin D plays a role in both MS and pregnancy health.

Navigating life with multiple sclerosis presents unique challenges. With careful planning and collaboration with your healthcare team however, it is entirely possible to have a healthy and successful pregnancy. Keep open lines of communication to ensure a comprehensive approach to your well-being and that of your growing family.
