1. Does Pregnancy Make Rheumatism Worse?
✅ Not always.

Some women experience a significant improvement in symptoms—especially during the second trimester—while others may see their symptoms worsen, particularly after childbirth. Every case is different, and individual responses can vary.

2. Does Rheumatism Affect Fertility?

✅ In most cases, rheumatism does not directly impact fertility.

However, some medications—such as methotrexate—can temporarily reduce fertility. It should be stopped well in advance of pregnancy and only under medical supervision.

---

3. Can Rheumatism Harm the Baby?

If the disease is well-controlled and you're on pregnancy-safe medications, a healthy pregnancy is possible.

⚠️ In certain conditions—such as systemic lupus erythematosus (SLE) or antiphospholipid syndrome—there’s a higher risk of complications like miscarriage or preterm birth.

---

4. What Rheumatism Medications Are Safe During Pregnancy?

✅ Some drugs are considered relatively safe, including:

• Hydroxychloroquine (Plaquenil)

• Sulfasalazine

• Prednisone, in moderate doses

❌ You must avoid:

• Methotrexate

• Leflunomide

• Certain biologics (unless prescribed with strict supervision)

---

5. Can You Breastfeed While on Rheumatism Medications?

✅ Yes, many rheumatism medications are safe during breastfeeding, such as hydroxychloroquine and low-dose corticosteroids.
Always consult your doctor before nursing while on any medication.

---

6. What Precautions Should Be Taken When Planning Pregnancy?

• Stop unsafe medications early, such as methotrexate

• Regular follow-up with a rheumatologist and high-risk pregnancy specialist

• Aim for stable disease status for at least 6 months before conception

---

7. What Tests Are Needed During Pregnancy?

Key tests include:

• ANA (Antinuclear Antibodies)

• Anti-Ro / Anti-La antibodies

• Clotting tests (e.g., antiphospholipid antibodies)

These help identify early risks that could affect the mother or fetus.

Types of Rheumatism That May Affect Pregnancy

If you're diagnosed with a rheumatic disease and planning for pregnancy, it’s important to understand which conditions are most common and how they behave during this period:

---

✅ 1. Rheumatoid Arthritis (RA)

• The most common type among women of childbearing age

• A chronic autoimmune disease that causes joint inflammation, pain, and stiffness

• Symptoms may improve during pregnancy, but often flare up postpartum

---

✅ 2. Systemic Lupus Erythematosus (SLE)

• A complex autoimmune condition affecting the skin, joints, kidneys, brain, and more

• Requires close monitoring during pregnancy due to risks of:

  • Preeclampsia

  • Preterm delivery

  • Fetal complications

• Plan pregnancy only after at least 6 months of disease stability

---

✅ 3. Ankylosing Spondylitis

• Affects the spine and pelvic joints

• Pregnancy usually does not worsen the disease

• May cause difficulty during vaginal delivery if the pelvic joints are severely affected

---

✅ 4. Psoriatic Arthritis

• A type of arthritis linked to psoriasis

• Symptoms may improve during pregnancy, but flares are common postpartum

---

✅ 5. Sjögren’s Syndrome

• An autoimmune disease that targets the glands that produce tears and saliva

• Can increase the risk of congenital heart block in the baby

• Requires monitoring by a specialist in immunology and maternal-fetal medicine

---

✅ 6. Vasculitis

• A group of autoimmune diseases that affect blood vessels

• Pregnancy is possible but demands intensive medical supervision to prevent serious complications

---

Causes of Rheumatism Flares or Onset During Pregnancy

Some women experience the first symptoms of rheumatism during pregnancy, or a worsening of pre-existing disease. Here's why:

---

1. Immune System Changes

Pregnancy alters the immune response to protect the fetus. These changes can trigger autoimmune diseases such as lupus or rheumatoid arthritis in susceptible women.

---

2. Hormonal Fluctuations

Increased levels of estrogen and progesterone during pregnancy affect immune activity and may:

• Reduce symptoms in some types of rheumatism

• Worsen symptoms in others

---

3. Mechanical Stress on Joints

Pregnancy weight gain puts extra pressure on the:

• Knees

• Pelvis

• Ankles

This can worsen joint pain and stiffness—especially in those already prone to joint issues.

---

4. Stopping Certain Medications

Discontinuing drugs like methotrexate for fetal safety can cause:

• Disease flare-ups

• A return of severe symptoms if no alternative is used

---

5. Vitamin D and Calcium Deficiency

Pregnancy depletes the mother’s reserves of calcium and vitamin D, which may lead to:

• Bone pain

• Increased joint discomfort

• Worsening of pre-existing osteoporosis or arthritis

---

Common Rheumatism Symptoms During Pregnancy

Symptoms vary depending on the disease, but common signs include:

• Joint pain and swelling, especially in the hands, wrists, knees, and ankles

• Morning stiffness that eases throughout the day

• Fatigue even with little physical effort

• Localized heat and redness in inflamed joints

• Low-grade fever, often seen in RA or lupus

• Butterfly-shaped facial rash (specific to lupus)

• Muscle weakness or stiffness due to inflammation or reduced mobility

• Sleep disturbances from nighttime pain or anxiety

• Mild to moderate anemia (common in chronic RA)

• Loss of appetite or weight, despite pregnancy, due to systemic inflammation

⚠️ Risks of Rheumatism During Pregnancy

Rheumatic diseases, if not well-managed, can pose risks for both the mother and the baby. However, with proper care and monitoring, many women with rheumatism have safe and healthy pregnancies.

✅ First: Risks to the Mother

1. Increased disease activity
Some women may experience flare-ups, particularly in the first or third trimester. Symptoms include:

• Severe joint pain

• Morning stiffness

• Difficulty moving

2. Heart or lung complications
Conditions like lupus or vasculitis may affect:

• Heart function

• Breathing capacity

• Oxygen levels

3. Anemia and kidney issues
Lupus nephritis can lead to:

• High blood pressure

• Protein loss in urine

• Swelling in the body

4. Higher risk of blood clots
Conditions like antiphospholipid syndrome (APS) increase the risk of:

• Deep vein thrombosis (DVT)

• Placental clots, which may affect the baby’s oxygen and nutrient supply

5. Medication adjustments
Drugs like methotrexate or retinoids must be discontinued before pregnancy.
⚠️ Stopping medications without a safe alternative can lead to disease flare-ups.

---

✅ Second: Risks to the Baby

1. Premature birth
In cases of active disease, especially lupus, babies may be born before 37 weeks.

2. Low birth weight
Chronic inflammation or some medications may affect fetal growth, resulting in a baby born underweight.

3. Miscarriage or stillbirth
Risks are higher if:

• Lupus is not well controlled

• Maternal antibodies such as Anti-Ro / SSA are present

4. Heart conditions in the baby
In rare cases, maternal antibodies can cause congenital heart block, a serious but uncommon complication requiring fetal heart monitoring (fetal echocardiography).

???? Medical Advice:

Pregnancy with rheumatic disease is possible, but it must be closely monitored by a rheumatologist and a high-risk pregnancy (maternal-fetal medicine) specialist. If possible, plan your pregnancy in advance to optimize health and reduce complications.

✅ How to Manage Rheumatism During Pregnancy

If you have autoimmune conditions like lupus or rheumatoid arthritis, pregnancy doesn't necessarily mean worsening symptoms. Here’s how to manage your condition safely:

1. Preconception planning
Consult your rheumatologist and OB-GYN before pregnancy.
???? Aim to have your disease in remission or under good control for at least 6 months before conceiving.

2. Medication adjustments
⚠️ Avoid the following drugs during pregnancy:

• Methotrexate

• Leflunomide

✅ Relatively safe medications include:

• Hydroxychloroquine (Plaquenil)

• Sulfasalazine

• Prednisone (at carefully controlled doses)

3. Regular monitoring
Frequent check-ups are essential to monitor:

• Disease activity

• Fetal development

• Complications like preeclampsia or hypertension

4. Healthy diet and light exercise

• Eat foods rich in calcium and vitamin D

• Engage in gentle activities like walking or prenatal yoga to reduce joint pain and improve circulation

5. Rest and stress management

• Prioritize sleep and mental well-being

• Avoid physical and emotional stress, which may trigger flare-ups

6. Delivery options
Rheumatic disease does not automatically require a C-section.
Natural delivery is possible unless complications (e.g., heart, pelvic, or kidney involvement) arise.

7. Disease activity may improve during pregnancy
Some women experience temporary relief during pregnancy due to immune changes.
⚠️ However, symptoms often return postpartum — continued follow-up is important.
