Lower Back Pain During Pregnancy – Causes & Treatment

Published on: 16 September , 2018 | Ekta

Back pain or discomfort during Pregnancy is a common phenomenon wherein the extent of discomfort varies from mild to extreme. The second half of pregnancy could be more taxing as back pain usually increases during that period. This is due to the simple fact that the baby growth is more rapid, thus applying more pressure on your spine which holds the weight of the growing baby and the uterus. Read more about Lower Back Pain During Pregnancy – Causes & Treatment.

During pregnancy, the body releases a hormone called ‘relaxin’ which helps the body to prepare for child birth. One of the effects of this hormone is that the ligaments throughout the body get loosened thereby reducing the stability of the pregnant woman and making her susceptible to weakness. A host of mechanical and hormonal factors lead to various discomforts during Pregnancy period, the most prominent being the lower back pain. Studies indicate that nearly 5 – 7 out of 10 pregnant women suffer from this body condition.

Lower Back Pain During Pregnancy – Causes & Treatment

What causes back pain during Pregnancy?

InLife HealthCare

The origin of the back pain is at the sacroiliac joint where the pelvis meets the spine. The common reasons are overweight/obesity, previous history of back pain.

Here is a list of the most common causes of back pain in pregnant women:

Excessive weight gain during pregnancy

The weight of the growing baby and the uterus puts pressure on the blood vessels and nerves in the pelvis and back resulting in back pain during pregnancy. A normal weight gain during pregnancy is anywhere between 11 – 15 kga. Beyond that it becomes difficult for the spine to hold on to the additional weight. This is the foremost reason for back pain in pregnant women. The pressure also pinches your sciatic nerve and causes the pain to run down the back of your legs.

Shift in the center of gravity

Pregnancy shifts your center of gravity – to a small extent, but it hardly gets noticed as your body adjusts to maintain it’s posture. This causes back pain or strain in many cases.

Change in posture or position during pregnancy

Wrong posture, standing on one leg, excessive standing, bending frequently over the waist are all the contributing factors. This results in you adjusting your posture and the way you move causing a strain on your back. According to NHS you should avoid lifting heavy objects right from your 1st trimester.

Stress during pregnancy

Emotional, physical or psychological stress levels also determine the well being of the expecting mother. An increase in the stress levels leads to severely tightening of muscles leading to chronic back pain. Emotional stress can cause your muscles to be tense in the back. This tension is then felt as pain or back spasms. This pain increases whenever you face stressful periods in your pregnancy.

Muscle separation

As the uterus expands, two sheets of muscles- the rectus abdominus run parallel from the rib cage to the pubic bone; they might get separated along the center seam causing severe back ache.

Previous health records

Any previous history of back pain, injury to the pelvis, hormonal imbalance, strenuous/monotonous work schedule, hypertension could all be the contributing factors for back pain or strain.

Hormonal changes during pregnancy

During pregnancy, the body releases a hormone called ‘relaxin’ which causes the loosening of the ligaments in your pelvis and makes the joints looser in preparation for the delivery process. So the ligaments around the back and spine also get loosened, thereby making it more susceptible to injury, instability & pain.

Fluid Retention & Oedema

Raised hormone levels cause your body to retain water during pregnancy. This causes your feet to get swollen and you feeling bloated. Your growing uterus puts pressure on the veins carrying blood back from your lower body partially blocked blood flow and retaining the fluid in your legs and feet.

How to treat back pain during pregnancy?

There is no established connection between 'pregnancy' and 'back pain'. However, the good news is that this pain will disappear gradually after the child’s birth, or in many cases even before that. There are 12 simple and practical tips we would like to share with you which help you to ease or minimize your back pain & swelling. Dealing with the pains during pregnancy can be very stressful. With the added weight and the pressure of the growing baby, the pains just cause a lot of added stress and strain.

Regular exercise during pregnancy

Following a regular exercise routine will help you both in the short run and long run to strengthen your body, especially the core muscles and back muscles. It boosts your muscle flexibility and helps you to strengthen your spine. The recommended activities could be swimming, walking, stationary cycling, squatting, yoga. Depending upon your health condition, your gynecologist would suggest you a preferred exercise regime; including stretching, tummy and stabilization exercises will be very helpful to keep you healthy and fit! Monitor your weight - While it is normal to gain about 10-15 kgs during pregnancy, excessive weight gain aggravates swellings and can lead to other complications.

Elevate your feet

Keep your feet raised upto 6-12 inches above the level of your heart for 15-20 minutes atleast 3-4 times a day. This helps in easy flow of blood back to your lungs and heart.

Dress up right

This might not seem that important a factor, but it actually is! Right from your inner wear to the shoes you choose to wear – everything should be well thought of before you make the choice. Choosing to wear loose fitting clothes, flat heels, wearing maternity garments which have supportive bands to support your belly, the right size of maternity bra are some of the pre requisites you need to look into when you plan your shopping list. The whole underlying idea is that you need to be comfortable while you move around so that oxygen supply to the muscles is the maximum.

Ideal sleep position during pregnancy


It is strictly restricted to sleep on the back. The ideal position would be to sleep on the side with a pregnancy pillow in between the legs so that the pressure on the back muscles is minimum. During pregnancy, try sleeping on your sides and not your back as this helps relieve the pressure on the vena cava. The vena cava is the largest draining vein leading to your heart.

Stop lifting weights during pregnancy

It is very important that you do not lift weights. In case you have a toddler to take care of, then bend at your knees or squat to lift him up. Or you could sit on the ground and allow him to climb your lap. in no situation you should bend at your waist, as it adversely affects your back strain.

Heat and Cold therapy/fermentation

Applying heat packs or cold packs on your back will help in providing temporary relief from your back pain. If your gynecologist approves of it, then you could resort to application of cold packs in the form of ice bags or wrapping up frozen vegetables in a cloth bag on the prone areas. You could repeat this for 7 – 10 times in a day. After a couple of day switch to heat pads application. This will help to ease out the strain. However care should be taken to not touch the abdomen area.
