Back Pain during Pregnancy: Why does it happen and How to deal with it?

Back Pain is the most common problem faced by women during their pregnancy. Though the back pain is more common by the third trimester but it can occur at any point of time during the pregnancy. This pain not only hampers the daily activities but also hinders the sleep.

Back pain is primarily due to the growth in the size of baby and the uterus which not only causes a deviation from the normal posture of the mothers’ body but is also responsible for the weakening of the abdominal muscles which in turn pressurizes the lower back. The secondary cause to the pain is the change in the hormone levels which loosens the joints around the region adjoining the pelvic and spinal region there by causing a sense of instability in the mother.

Types of Back Pain during Pregnancy

Back Pain due to pregnancy can be categorized as:

  • Posterior Pelvic Pain: It is more common in pregnant woman who have to stay in one posture for a prolonged period. The pain radiates form the tail bone and spreads under the entire waistline. The pain can limit itself to one side of the pelvis or it can strain both sides depending on the severity. In severe cases, the pain can outspread to thigh and hip region up to the knees. Patients usually feel stiffness around the region which is not easy to treat. Prime reasons that can aggravate the pain are:

– Rolling in the bed when lying down
– Climbing up and down the stairs
– Remain seated in one position for a long time
– Sudden rising up from the seated posture
– Lifting heavy objects
– Twisting around and bending forward
– Brisk walking and running.

  • Lower Back Pain: It is also known as the “Lumbar Pain”. This pain is usually localized in the center of the back region lying just above the waist. The pain usually arises due to soreness in muscles which are present around the spine area. Prolonged postures like sitting, standing or frequent lifting of heavy objects are known to worsen the pain.

Sometimes, the lumbar pain can also co-exist with a radiating pain in the leg or foot region, this condition is known as Sciatica. In this condition, the pain originates from the lower back down to the foot through the hip region causing a sense of pain along with tingling and numbness.

What are the reasons for Back Pain during Pregnancy?

There are multiple reasons behind the pregnancy back pain, some of which are mentioned below:

  • Increase in Weight: For a healthy pregnancy, a woman is expected to gain weight around 25 to 35 pounds; this increase in weight has to be supported by the spine. If it is not supported, it starts causing the lower back pain in the mother. Apart from this the weight of the developing baby encapsulated in the expanding uterus also exerts a lot of pressure on the blood vessels and nerves in the pelvic region and the lower back area. This also adds to the back pain.
  • Change in Posture:Pregnancy causes a change in the balance point of the mother’s body which gradually makes way to a posture that is a precursor to pressure on the back thereby causing back pain. The body unknowingly gives in to the change in posture.
  • Hormonal fluctuations:During pregnancy, the body causes the ligaments in the pelvic region to relax so as to allow the joints to become loose which aids in easing the birth process. This loosening in the joints is caused due to release of a hormone called Relaxin which is also responsible for loosening the ligaments that support the spine leading to instability in the body and pain in the back.
  • Muscle separation:The abdominal muscles that starts from the rib cage to the pubic bone, comprises of two sheets that might get separated along the center joint due to expansion in the size of uterus thus increasing the severity in back pain.
  • Stress: Stress is the root cause of many problems, so is it in case of back pain during pregnancy. Stress can cause the muscles in the back area to get tensed, which may cause in back pain or back spasms. It is common for expecting mothers to face an increase in back pain during stressful phases of pregnancy.
