Many mothers-to-be these days have been experiencing SI joint pain pregnancy due to the many additional weight and hormonal changes. This pain typically manifests around the lower back and hips and can be remedied by simple solutions like using a Momcozy Ergonest Maternity Belly Band.
What Is The Sacroiliac Joint
The sacroiliac joint links the spine to the pelvis and carries weight during movement. Problems in this joint can lead to SI joint pain while pregnant. The sacroiliac joint can be:
- A strong link between the lower spine and pelvis
- A weight distributor for the upper body to the legs
- A shock absorber when standing, walking, or moving
- A stabilizer that helps with balance during pregnancy
- A support for posture throughout daily activities
The body experiences difficulties in various ways when the sacroiliac joint malfunctions. During pregnancy, the additional weight, hormone variations, and changed posture are the factors that lead to an increased load on the joint. And this is the reason why many pregnant women end up with pain in that area.

Causes Of Sacroiliac Joint Issues During Pregnancy
These are the typical reasons for sacroiliac joint pain during pregnancy:
Hormonal Changes
During pregnancy, the body emits relaxin which is a hormone that loosens the ligaments in the pelvic area to make things easier during birth. Though the loosened joints are beneficial for the delivery, they can also cause the sacroiliac joint to be unstable which is a factor for the pain in the lower back and hips.
Weight Gain and Added Pressure
As the baby develops, there is additional weight that puts pressure on the sacroiliac joint. The pelvis, which is the support for the mother’s body and the baby, can be a source of increased stress on the joint.
Postural Changes
Pregnant women usually change their posture to counterbalance the bulging belly. The rearrangement of the body causes the pelvis and lower back to be struck unevenly by the strain, which is the reason the sacroiliac joint is giving off an ache.
Weakened Core Muscles
The stomach muscles have been extended to accommodate the baby and weakening the core strength. When the core is weak, it becomes difficult to support the pelvis and spine, thus more sacroiliac joint pressure is felt.
Previous Joint Problems
Women who already had lower back or pelvic issues before pregnancy may feel the pain more strongly. An existing weakness or injury increases the chance of SI joint pain while pregnant.

Symptoms Of Sacroiliac Joint Issues in Pregnancy
SI joint pain pregnancy is frequently misinterpreted as lower back pain, as it is a common area where the trouble might have come from. It can range from mild to severe. Its symptoms may include:
- Discomfort that originates in the lower back area and radiates into the buttocks or thighs
- Aching that intensifies when standing up, climbing stairs, or turning in bed
- The pain is quite severe and limited to the one side of the hip that becomes more apparent when you walk so walking faster cannot be done
- Stiffness in the lower back after sitting or lying down for a long time
- In severe cases, moms with SI joint pain pregnancy can’t walk without difficulty

Risk Factors Of Sacroiliac Joint Issues while Pregnant
Sacroiliac joint pain and pregnancy often go together because the body goes through many changes that affect the pelvis and lower back. The common risk factors include:
- Injuries to the lower back that have reduced the strength of the sacroiliac joint
- A fast increase in body weight while being pregnant that led to higher pressure on the pelvic area
- The condition of being pregnant with twins or multiples, , which adds extra strain on the joints
- Poor posture that causes the spine and pelvis to be subjected to uneven stress
- Family history of joint problems that raise the chance of discomfort
What Are The Complications Of Sacroiliac Joint Issues During Pregnancy
Problems with the sacroiliac joint may interfere with movement, posture, and even rest of pregnant women. Many mothers who deal with SI joint pain pregnancy notice that the discomfort affects more than just their lower back. The possible complications can be:
- Restricted movement that causes difficulty in walking or going up stairs
- Sleeping problems due to hip or lower back pain
- Overloading with stress on the surrounding muscles, which results in more pain
- Greater risk of falls when balance is affected by joint pain
- Episodes where SI joint pain during pregnancy causes difficulty standing up
- Long-term strain on the pelvis that may extend into the postpartum period
How To Manage Pregnancy-Related SI Joint Pain
