Back pain during pregnancy is usually common a complaint. It’s not unusual as you’re gaining weight. You are walking and moving in a different way as your hormones are calming the muscles and ligaments throughout your body. This can be a week by week pregnancy occurrence.
50 to 70 percent of expectant mothers experience pregnancy back pain as it often begins in the second half of conception as changes in your body weight and center of gravity put added strain on your spine.
A study was done in America on pregnancy back pain prevalence and the results were astounding as it was both troubling and consoling at the same time. Back pain during pregnancy occurs mostly in the 36th week of pregnancy as the mother suffers from lower back and pelvis pain.
The most comforting and appeasing information this study offers is the fact that pregnancy back pain subsides three months after the delivery.
Back Pain during Pregnancy – Symptoms
Back pain during pregnancy are often dull, persistent aches over the lower back area that typically affects younger women, those who have had multiple pregnancies and those who possess weak backs.
For most women, the sacroiliac joint is where the pain often originates. This is where the pelvis attaches to the spine. Pregnancy back pain may begin as stiffness in the morning and then progress to soreness through the day.
Causes of Back Pain during Pregnancy
Back pain during pregnancy is one of those pregnancy problems that can affect the majority of child-bearing women because of the following causes:
Changes in posture, fetal growth and movement
Your uterus expands as your fetus grows and this shifts your center of gravity as it stretches out and weakens your abdominal muscles. This is a week by week pregnancy event that changes your posture and movement, eventually putting a strain on your back.
Women normally gain 25 and 35 pounds of weight during a healthy pregnancy. This pregnancy weight gain is then supported by the spine, which can cause a discomfort in your lower back. Furthermore, the pressure on the blood vessels and nerves in the pelvis and back are manifested due to the growing baby and uterus.
Your body produces a hormone called relaxin, during pregnancy that allows ligaments in the pelvic area to relax, loosens the joints in preparation for the birth process. This can cause ligaments that hold up the spine to loosen up a bit, which can lead to instability and back pain during pregnancy.
This is one of pregnancy problems that can make you feel less stable as it causes pain when you walk, stand, and sit for long periods, bend, or even lift things. In short, this makes moving a problem.
Another cause of back pain during pregnancy is the fact that as your uterus expands; two corresponding sheets of muscles called “rectal abdominis” may split along the center layer. This may worsen pregnancy back pain.
Emotional stress can be the source of muscle tension in the back, which may be reflected as pregnancy back pain. You may find that you experience an increase in back pain during pregnancy when stress is great.
