Path to improved well being
There are several causes of back pain during pregnancy. These are due to changes that occur in your body.
- Pressure on back muscles. As your baby grows, your uterus expands and becomes heavier. This puts added weight on your back muscles. You may find yourself leaning backward or arching your low back. The pressure can lead to back pain or stiffness.
- Weakness in stomach muscles. Your growing baby also puts pressure on your stomach muscles. This can cause them to stretch and weaken. Your stomach and back muscles are connected. Your back muscles have to work harder to offset your belly.
- Pregnancy can alter your center of gravity. The way you move, sit, and stand can cause pain to your back and other parts of your body. A compressed nerve due to poor posture also can cause pain.
- Pregnancy hormones. Many hormones change when you are pregnant for different reasons. Later in your pregnancy, hormones increase to relax the muscles and ligaments in your pelvis. This prepares your body for labor. If your muscles and ligaments become too loose, it can lead to back pain.
- Anxiety and built-up tension can make your back muscles tight or stiff.
To help prevent back pain, be mindful of how you sit, stand, sleep, and move.
- Sit in a way that supports your back. Choose a lumbar chair or place a pillow behind your low back. Try propping your feet up to increase blood flow and prevent slouching.
- Sit and stand up straight. Try to keep your back in line with your bottom and legs rather than arch your low back. Do not sit or stand in the same position for a prolonged time. It could pinch a nerve. Do not lock your knees. If you have to stand for long periods, try resting one foot at a time on a box or stool.
- Wear low-heeled shoes that are comfortable and provide support to your whole body. It may help to use arch support inserts. Avoid shoes with heels that can knock you off balance.
- Sleep with a mattress that isn’t too soft and offers support. When you are pregnant, it is best to sleep on your side. Place pillows under your stomach and between your legs for added support. Try to avoid sleeping on your back. This can put pressure on your uterus and cut off blood flow to your baby.
- Do not twist or make sudden movements that could strain your back or stomach muscles.
- Do not lift things by bending forward. Instead, keep your back straight and lift with your legs, not your back. Be careful not to lift or carry too much weight at once.
- Get plenty of exercise. This will help strengthen your back and stomach muscles and improve your posture. Talk to your healthcare provider about what type of exercise is safe. Walking and swimming often are fine. If you were very active before pregnancy, you may be able to continue doing the same level of activity. Certain moves and stretches, such as Kegel exercises, also prepare you for labour.
- Wear maternity pants. The wide elastic waistband provides extra support.
If you have back pain, these tips can help relieve soreness and stiffness.
- Apply heat or a cold compress to your back. Avoid putting extreme temperatures on your stomach.
- Take acetaminophen (brand name: Tylenol) if approved by your healthcare provider.
- Find ways to relieve stress. Learn breathing exercises or take a prenatal yoga class.
- Get a prenatal massage from a certified therapist.
- Ask your healthcare provider about alternative medicine. This could include acupuncture or a chiropractic adjustment. It could also include osteopathic manipulation. Your muscles and joints are moved through stretching and using gentle pressure.
