arthritis in pregnancy

Overview

Arthritis is a long-term condition that causes pain, swelling, and stiffness in the joints. When you are pregnant, arthritis can affect how you feel day to day, and pregnancy can change the way your arthritis behaves. With the right care, most women with arthritis have a healthy pregnancy and baby.

Arthritis is one of the most common long-term conditions among women of childbearing age. While not every pregnant woman has it, many pregnant women already live with arthritis or develop joint symptoms for the first time during pregnancy.

It can affect anyone who is pregnant, especially women who already have inflammatory arthritis such as rheumatoid arthritis or psoriatic arthritis. Osteoarthritis — the wear-and-tear type — can also feel more painful during pregnancy because of weight gain and posture changes.

Symptoms

Common symptoms

• Pain, aching, or tenderness in one or more joints
• Swelling or redness around a joint
• Stiffness, especially in the morning or after rest
• Reduced range of motion — trouble bending or straightening a joint
• Fatigue or tiredness that comes with joint pain

Symptoms in children

• This article is about arthritis during pregnancy. For children, arthritis is a separate condition that can cause joint swelling, pain, and stiff movement — if you have concerns about a child, see a pediatrician.

Symptoms in older adults

• Older women who become pregnant may already have osteoarthritis, which can cause knee, hip, or hand pain that may worsen during pregnancy due to extra weight and changing posture.

Causes

Main causes

• Arthritis happens when the joints become inflamed (swollen and painful) or when protective cartilage wears down.
• During pregnancy, your body makes hormones that relax the joints and ligaments, which can change how stable and painful your joints feel.
• Weight gain and shifting posture during pregnancy place extra stress on weight-bearing joints like the hips, knees, and back.
• In inflammatory arthritis (like rheumatoid arthritis), the immune system may change during pregnancy — sometimes calming symptoms, sometimes causing a flare.

Risk factors

• Having a type of arthritis before pregnancy
• A family history of arthritis or other autoimmune conditions
• Being overweight before pregnancy
• Previous joint injury or wear-and-tear
• Pregnancy-related changes like weight gain and hormone shifts

When to see a doctor

See a doctor urgently if:

• Sudden, severe joint swelling or pain that stops you from using a joint
• A hot, red, or very painful joint — this could mean an infection
• Any joint pain that comes with a fever or feeling generally unwell

Book a routine appointment if:

• If you have arthritis and are thinking about getting pregnant — talk to your doctor before you conceive
• During pregnancy, keep your regular check-ups so your healthcare team can review how your joints are doing
• If you notice new joint pain or stiffness, or existing symptoms are getting worse, make an appointment

Diagnosis

Your doctor will ask about your symptoms, your medical history, and how your joints feel day to day. They will examine your joints by looking for swelling, warmth, and any limits in movement. If they think you have a specific type of arthritis, they may recommend tests.

Tests that may be done

• Blood tests to look for inflammation or certain antibodies
• Urine tests to check for signs of inflammation or protein
• Imaging tests like ultrasound or MRI, which are thought to be safe in pregnancy — your doctor will explain why they are needed

What to expect at your appointment

Diagnosis can take a little time. Your doctor will work with your maternity team, and possibly a rheumatologist (a doctor who specialises in joints), to understand your symptoms and plan care that is safe for you and your baby. You don't need to be an expert — just be honest about what you're feeling.

Treatment

Treatment for arthritis in pregnancy focuses on managing pain and inflammation while keeping you and your baby safe. Your healthcare team will help you choose a plan based on your symptoms, your type of arthritis, and your stage of pregnancy.

Self-care at home

• Use warm or cold packs on painful joints (ask your doctor which is best for you)
• Rest when you need to and break tasks into smaller steps
• Gentle exercise like walking, swimming, or prenatal yoga – with your doctor's permission
• Wear supportive shoes and avoid high heels
• Try pregnancy pillows or cushions to help you sleep more comfortably
• Ask for help with lifting and housework when you can

Medical treatments

Some medicines can be used to treat arthritis during pregnancy, but only under the close supervision of a qualified healthcare provider. Your doctor may adjust your current medicines or suggest other options. Never start, stop, or change any medicine without talking to your doctor first.

When is surgery considered?

Surgery for arthritis is usually not done during pregnancy. Joint surgery or joint replacement is typically delayed until after you have had your baby, unless there is an emergency that requires immediate care.

Living with this condition

Take things at your own pace. Plan your day so you have time for rest and gentle movement. Tell your midwife or doctor about your joint symptoms at every appointment. Small changes — like using long-handled tools, a grabber, or grips that are easier to hold — can make a big difference.

Lifestyle tips

• Keep a steady daily routine with balanced activities and rest
• Guard your joints: use larger joints for carrying, and avoid gripping too hard
• Stay in touch with your healthcare team and be honest about your pain levels
• Stay active with low-impact exercise as approved by your doctor
• Ask for help from family and friends when needed

Diet and exercise

Eat a balanced diet with plenty of fruit, vegetables, whole grains, and protein. Staying active with gentle, low-impact activities like walking or prenatal yoga can help keep joints moving and reduce stiffness. Some people find that certain foods make their arthritis worse, but there is no one-size-fits-all diet. Always talk to your doctor before starting a new exercise or taking any supplement.

Mental health and emotional wellbeing

Living with joint pain while pregnant can be stressful and tiring. It is normal to feel frustrated, anxious, or low at times. Your emotional health matters just as much as your physical health. Talk to your midwife or doctor if you feel overwhelmed — they can connect you with counselling or support groups.

Prevention

Arthritis cannot always be prevented, especially if you have an inflammatory joint condition. However, staying at a healthy weight, keeping active, and protecting your joints may help reduce the severity of symptoms. If you are planning pregnancy, talking to your doctor beforehand is the best way to prepare.

Vaccines

Some vaccines are advised before or during pregnancy to protect you and your baby from infections. Talk to your midwife or doctor about which vaccines are right for your situation and timing.

Screening programmes

If you have arthritis, your healthcare team may monitor your blood pressure, urine, and overall wellbeing during pregnancy. This is not to worry you — it is to catch and manage any potential complications early.

Complications

If left untreated

• Constant joint pain could make daily activities very difficult
• High levels of inflammation in some types of arthritis may increase the risk of early birth or low birth weight
• Some medicines used for arthritis may not be safe in pregnancy — another reason to review your treatment plan before and during pregnancy

Long-term outlook

The good news is that many women with arthritis have healthy pregnancies and healthy babies. With careful planning, a supportive healthcare team, and simple self-care strategies, you can manage joint symptoms and enjoy your pregnancy. Even if your arthritis flares, there are safe ways to help you cope.
