If you are pregnant or thinking about having a baby soon, your mind is probably full of questions. This is a very normal and exciting time in your life. You might wonder about feeding your baby, coping with labor, or eating the right foods.

However, if you live with ankylosing spondylitis, your worries might look a little different. You may wonder if you can get pregnant safely, or if your condition will affect your baby. This guide is here to help you understand what to expect.

Can You Get Pregnant with Ankylosing Spondylitis?

The best news is that ankylosing spondylitis does not harm your fertility. You can get pregnant just like anyone else. However, you need to plan ahead much earlier than someone without this condition.

Some medicines you take for your joints can cause birth defects. Because of this, your doctor may ask you to stop these medicines weeks or months before you try to get pregnant.

Using a reliable birth control method is a great way to time your pregnancy safely. Many women use intrauterine devices, known as IUDs. These are small, T-shaped plastic devices placed inside your womb by your doctor.

When you are ready to start a family, talk to your doctor right away. They will review your medicine list and help you switch to safer options. They will also remove your IUD and guide you on managing your joint symptoms.

Fathers-to-be should also pay attention to their medicines. Studies show that drugs like sulfasalazine and cyclophosphamide can lower sperm counts in men. If you and your partner are planning a family, make sure your doctor knows about all the medicines you take.

Can AS Cause Complications During Pregnancy?

Most medical studies show that ankylosing spondylitis does not cause severe pregnancy complications. The vast majority of women with this condition give birth to healthy babies. The risk of a miscarriage is no higher than it is for the general population.

However, if your joint disease is very severe, your risks may be higher. High blood pressure during pregnancy, known as preeclampsia, can also increase risks. This condition is dangerous for both mother and baby and requires close monitoring by your medical team.

To help you understand what doctors watch for, here is a helpful breakdown of potential risks:

Potential Complication What It Means for You
Preterm Birth Your baby might arrive before the 37th week of your pregnancy.
Low Birth Weight Your newborn may weigh slightly less than average at birth.
C-Section Delivery You might need a surgical delivery through your abdomen.
NICU Admission Your baby may need special care in the neonatal intensive care unit.

Will My AS Symptoms Worsen During Pregnancy?

As your baby grows, your body weight increases steadily over nine months. This extra weight puts heavy pressure on your joints, muscles, and lower back. Because of this, you may feel more stiffness and pain as you reach your second and third trimesters.

An unexpected flare-up can happen at any time during pregnancy. One major study found that about 80 percent of women with ankylosing spondylitis experience a flare-up. Symptoms often get worse in the months after giving birth as well. The good news is that these symptoms usually settle down over time.

Every woman's body reacts differently to pregnancy. Some expectant mothers notice no change in their joint symptoms at all. In very rare cases, some women even experience a temporary drop in their pain levels.

What to Expect During Pregnancy

Navigating pregnancy with a chronic condition takes careful planning and teamwork with your doctors. Let us look at three important areas you should understand.

Medicines and Baby Growth

Your doctor will help you balance your pain control with the safety of your growing baby. If safe options exist, you can continue taking certain medicines to manage your inflammation.

Nonsteroidal anti-inflammatory drugs, or NSAIDs, include common medicines like ibuprofen, naproxen, celecoxib, and aspirin. Doctors usually consider these safe during the first 20 weeks of pregnancy.

Taking NSAIDs after 20 weeks can cause serious kidney and heart problems for your baby. Always consult your doctor before taking any medicine during pregnancy.

Will AS Go to Your Baby?

Autoimmune conditions like ankylosing spondylitis have a strong genetic link. If you carry a specific gene marker called HLA-B27, you have a 50 percent chance of passing it to your child.

However, carrying this gene does not mean your baby will definitely develop the disease. Medical studies show that only about 20 percent of children who inherit the gene ever develop ankylosing spondylitis.

AS and Childbirth

Many women with ankylosing spondylitis have normal, healthy vaginal deliveries. However, your condition can affect your pelvis, hips, and fused spine, making vaginal birth more challenging.

Spine inflammation can also make it difficult for doctors to place an epidural. An epidural is an injection into your lower back given by an anesthesiologist to block labor pain.

Talk to your obstetrician and your anesthesiologist early in your pregnancy. Ask if they have experience treating patients with ankylosing spondylitis. They can discuss your options and schedule a C-section if vaginal delivery is too risky.

Caring for Your Baby After Birth

Taking care of a newborn baby requires a lot of physical energy and sleep. If you have joint pain, this stage of life can test your patience and strength.

Breastfeeding is generally safe with ankylosing spondylitis. Many joint medicines are safe to use while nursing your baby. However, small amounts of some drugs can pass into your breast milk.

Always talk to your doctor about your medicine plan before you start breastfeeding. They will help you choose options that keep your baby completely safe.

Your disease symptoms often flare up during the first few months postpartum. If this happens, schedule a visit with your rheumatologist to adjust your treatment plan.

Simple daily tasks like lifting your baby, changing diapers, and slouching during feedings can strain your back. Arrange for family members or friends to help you at home before your baby arrives.

Do not hesitate to hire extra help if you can afford it. Remember to eat nutritious foods and rest whenever your baby sleeps so your body can heal.

💡 Take-Home Message

Ankylosing spondylitis does not stop you from having a wonderful family. Talk to your healthcare team early to build a safe roadmap for pregnancy.

Expect your symptoms to shift during pregnancy and after delivery, and stay in close contact with your doctors. Never hesitate to lean on your support system when daily chores feel heavy.

When to Seek Emergency Medical Care

Call 911 (US/Canada), 999 (UK), or go to your nearest Emergency Department right away if you experience any of these red flag symptoms during pregnancy:

  • Severe vaginal bleeding or fluid leakage before your due date.
  • Sudden, severe headaches, vision changes, or upper stomach pain (signs of preeclampsia).
  • Sudden decrease in your baby's movements.
  • Severe chest pain, shortness of breath, or sudden high fever.
❓ FAQ

Frequently Asked Medical Questions (FAQ)

Evidence-based clinical answers to common patient questions

Does ankylosing spondylitis stop me from getting pregnant?

No, ankylosing spondylitis does not harm your natural fertility or your ability to conceive. Women with this condition can get pregnant successfully, though planning ahead with your doctor is essential for medicine safety.

Are AS medicines safe to take while pregnant?

Some medicines like certain NSAIDs are safe during the first 20 weeks of pregnancy. Other strong drugs must be stopped beforehand. Always consult your doctor to review your prescriptions safely.

Will my baby inherit ankylosing spondylitis?

There is a genetic link through the HLA-B27 marker, giving a 50 percent chance of passing the gene. However, only a fraction of children who inherit this gene will ever develop the disease.

Can I have a normal vaginal delivery with a fused spine?

Many women have smooth vaginal deliveries. However, spinal fusion and pelvic pressure can make delivery harder. Your obstetrician may discuss a C-section if vaginal birth poses too many risks.

What happens to my AS symptoms after birth?

Your symptoms may flare up or worsen in the first few months after giving body delivery due to physical stress and sleep loss. Your rheumatologist can help adjust your care plan during this time.

Can I breastfeed while taking medicine for AS?

Yes, many medicines are safe during breastfeeding. A small amount of certain drugs can pass into breast milk, so check with your pediatrician and rheumatologist before nursing.
