Back pain is one of the most common complaints during pregnancy. As your body grows and changes to support your baby, added weight, shifting posture, and hormone fluctuations can all contribute to discomfort in your lower or upper back. While it’s a normal part of the pregnancy journey, that doesn’t mean you should suffer through it without relief.
Why Back Pain Happens During Pregnancy
Pregnancy changes nearly every part of your body, and the spine is no exception. For many people, back pain begins in the second half of pregnancy and can range from mild aches to persistent pain that interferes with daily activities.
Common Causes of Back Pain
- Weight gain: The average weight gained during pregnancy is typically between 25 and 35 pounds, although it can vary significantly. This additional weight puts pressure on the spine, especially the lower back.
- Postural changes: As your uterus expands, your center of gravity shifts forward. Many unconsciously adjust their posture to maintain balance, leading to muscle strain.
- Hormonal effects: Pregnancy hormones, especially relaxin, cause ligaments in your pelvis and spine to loosen. While this prepares your body for birth, it also makes joints less stable and more prone to strain.
- Muscle separation: The growing uterus can cause the abdominal muscles (specifically the rectus abdominis) to separate, a condition known as diastasis recti. Weakened core muscles can lead to extra pressure on your back.
- Stress: Physical stress isn’t the only culprit. Emotional stress can cause muscle tension, especially in the back and shoulders.
What Types of Back Pain Are Common?
Not all pregnancy-related back pain feels the same. Understanding where and how it hurts can help you and your provider identify the cause.
Lower Back Pain (Lumbar Pain)
This is the most typical type of pregnancy-related back pain. It’s felt just above the waistline and often worsens with prolonged sitting, standing, or lifting. Lumbar pain tends to be deeper and more persistent.
Pelvic Girdle Pain (PGP)
PGP affects the back of the pelvis and may radiate to the thighs or hips. It often feels like a sharp, stabbing pain near the tailbone or on one side of the buttocks. Getting in and out of a car, walking upstairs, or turning in bed can worsen the discomfort.
Upper Back Pain
While less common, some people experience pain in the upper back or between the shoulder blades. This can be caused by poor posture or the strain of larger breasts during pregnancy.
When to Talk to Your Provider
Back pain is often manageable, but it’s important to know when it might be signaling something more serious.
Reach out to your provider if you experience:
- Sudden or severe back pain that doesn’t go away
- Pain accompanied by fever or burning during urination (could indicate a kidney infection)
- Numbness, tingling, or weakness in the legs
- Difficulty walking or a feeling of instability
- Back pain combined with vaginal bleeding or cramping
These symptoms may point to conditions that require immediate medical attention.
Safe and Effective Relief Techniques
The good news? There are several ways to manage and relieve pregnancy-related back pain. Most of them are simple, drug-free, and easy to do at home.
Practice Good Posture
As your body changes, so should the way you move and stand. Try these adjustments:
- Stand tall with shoulders relaxed and back
- Keep your feet hip-width apart for stability.
- Avoid locking your knees
- Use a footrest to take pressure off your lower back when sitting
Use Supportive Gear
- Maternity support belts can help distribute the weight of your belly more evenly and take pressure off your lower back
- Supportive shoes (with low heels and good arch support) reduce strain when walking or standing
- Pregnancy pillows offer back and belly support when sleeping, especially when placed between the knees or under the abdomen
Stay Active with Pregnancy-Safe Exercises
Gentle exercise helps strengthen back and abdominal muscles while improving flexibility and circulation. Talk to your provider before starting any new activity.
Safe options include:
- Prenatal yoga
- Swimming or water aerobics
- Walking
- Pelvic tilts and stretching
Avoid any exercises that involve lying flat on your back after the first trimester or that cause pain or discomfort.
Try Heat and Cold Therapy
A heating pad on your lower back for 20 minutes can help ease tight muscles. Cold packs may reduce inflammation. Always place a towel between your skin and the heat or ice, and don’t apply for extended periods.
Schedule Prenatal Massage
Many pregnant patients find relief through a prenatal massage, which can help reduce muscle tension and promote relaxation. Make sure your therapist is trained in prenatal care.
Focus on Sleep Positioning
Sleep on your side (preferably the left) with a pillow between your knees and under your belly to keep your spine aligned. Avoid sleeping on your back after 20 weeks, as this can put pressure on major blood vessels and worsen back discomfort.
Preventing Back Pain Later in Pregnancy
As your pregnancy progresses, these preventive habits can help reduce the likelihood of worsening back pain:
- Don’t lift heavy objects, and use your legs instead of your back when lifting anything
- Take breaks throughout the day to stretch and change positions
- Sit in chairs with good lumbar support, or place a small pillow behind your lower back
- Stay hydrated and maintain a healthy weight gain based on your provider’s guidance
Back pain may be common during pregnancy, but that doesn’t mean you have to suffer through it. By understanding the causes and taking proactive steps, you can reduce discomfort and enjoy a healthier, more comfortable pregnancy.
