Pregnancy can include many joyous moments, like hearing your baby’s heartbeat for the first time or seeing them on an ultrasound screen. A fair amount of aches and pains can also be involved.

Experts estimate that 50% of people experience lower back pain during their pregnancy or postpartum.

Read on for more information about lower back pain in pregnancy and what you can do to feel better.

If you’re experiencing lower back pain during pregnancy, you may try things like:

  • applying hot and cold packs to your lower back
  • wearing a supportive pregnancy belt
  • stretching frequently
  • sleeping on your left side while using supportive pillows
  • talking with a chiropractor or acupuncturist

In some cases, back pain may be due to an infection. If you’re experiencing signs of a urinary tract infection (UTI), like a fever or bloody discharge, it’s important to let your doctor know so they can provide the appropriate medications.

Lower back pain during pregnancy is usually associated with:

  • hormone changes
  • a shifted center of gravity

During pregnancy, your abdominal muscles stretch and weaken, which can change your posture and put a strain on your back. Pregnancy hormones also relax the ligaments in the joints of the pelvis and may lead to lower back pain.

Lower back pain during pregnancy is extremely common and may not require any further diagnosis.

If your doctor is concerned about your lower back pain or thinks it might not be pregnancy-related, they may consider diagnostic imaging.

Ultrasound and MRI testing are typically safe during pregnancy, but doctors only recommend them if they believe they could answer a medical question or provide a health benefit.

While you may not be able to fully prevent lower back pain during pregnancy, some things you can do to minimize it and increase your comfort include:

  • rucking a small pillow behind your lower back when sitting in a chair
  • avoiding lifting heavy objects
  • choosing shoes with good arch support that aren’t heels
  • balancing weight by carrying shopping bags and other items in both hands
  • focusing on good posture
  • exercising regularly

Standing for a long period of time increased lower back pain for 27.2% of pregnant women in one study. However, over 40% of pregnant women in the study were able to reduce back pain by resting.

While resting throughout the day can help lower back pain, nearly two-thirds of the pregnant women reported that back pain worsened during the night.

Many individuals experience relief in lower back pain shortly after they deliver the baby or within a few months of being postpartum.
