Your health matters just as much as your baby's. If you are dealing with hip pain during pregnancy, here is what you need to know.

The short answer

Hip pain affects many pregnant people, particularly in the second and third trimesters. It is caused by the hormone relaxin loosening hip joints, weight gain changing your gait, the growing belly shifting your center of gravity, and the pressure of side sleeping. It is usually treatable with stretching, support pillows, and gentle exercise.

What Parents Should Know

According to ACOG, NIH, March of Dimes guidelines, hip pain affects many pregnant people, particularly in the second and third trimesters. It is caused by the hormone relaxin loosening hip joints, weight gain changing your gait, the growing belly shifting your center of gravity, and the pressure of side sleeping. It is usually treatable with stretching, support pillows, and gentle exercise. At Second trimester, hip pain may begin in the second trimester as the hormone relaxin loosens ligaments and joints. Gentle hip stretches, prenatal yoga, and swimming can help maintain mobility and reduce pain. A pregnancy pillow between your knees while sleeping can significantly improve nighttime hip pain. It is generally considered normal when aching hips, especially at night from side sleeping. However, you should contact your pediatrician promptly if sudden severe hip pain with inability to bear weight, which could indicate a joint or bone issue.

By Age

What to expect by age

Second trimester

Hip pain may begin in the second trimester as the hormone relaxin loosens ligaments and joints. Gentle hip stretches, prenatal yoga, and swimming can help maintain mobility and reduce pain. A pregnancy pillow between your knees while sleeping can significantly improve nighttime hip pain.

Third trimester

Hip pain is often worst in the third trimester due to maximum weight and joint laxity. Sleeping on your side with a pillow between your knees and under your belly is recommended. Alternating sides during the night, warm baths, and gentle stretching before bed can help. A physical therapist experienced with pregnancy can provide targeted exercises.

Postpartum

Hip pain usually improves after delivery as relaxin levels decrease and joint stability returns. Recovery may take weeks to months. Gentle postpartum exercises focusing on hip and core strengthening can speed recovery. If hip pain persists beyond a few months, consult your provider.

What to Tell Your Pediatrician

  • Describe when you first noticed hip pain during pregnancy and how it has changed over time.
  • Note your baby's current age and which age-specific patterns you are seeing.
  • Mention if hip pain is severe enough to limit walking or daily activities.
  • Mention if pain is sharp and sudden rather than a gradual ache.
  • Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
  • Bring a list of any questions or observations you want to discuss at the appointment.

What You Can Do at Home

Symphysis Pubis Dysfunction (SPD/PGP)

Symphysis pubis dysfunction (SPD), also called pelvic girdle pain (PGP), occurs when the joint at the front of the pelvis becomes too loose during pregnancy, causing pain, instability, and difficulty walking. It affects about 1 in 5 pregnant people to some degree. It is caused by the hormone relaxin and the weight of the growing baby.

Back Pain During Pregnancy

Back pain affects approximately 50-70% of pregnant people and is most common in the second and third trimesters. It is usually caused by the shifting center of gravity, weight gain, hormonal changes that loosen ligaments, and postural adjustments as the belly grows.

Sciatic Nerve Pain in Pregnancy

Sciatica during pregnancy involves pain that radiates along the sciatic nerve, from the lower back through the buttock and down the leg. It affects roughly 1% of pregnant people and is caused by the growing uterus putting pressure on the sciatic nerve, hormonal changes loosening joints, or the baby's position.

Dealing with Abnormal Prenatal Screening Results

An abnormal prenatal screening result can be terrifying, but it is important to understand that screening tests are designed to cast a wide net and have significant false-positive rates. Most people with abnormal screening results go on to have healthy babies after further testing confirms the baby is fine. An abnormal screening is a reason for more information, not a diagnosis.

Pregnancy Over 35 (Advanced Maternal Age)

While pregnancy after 35 carries some increased risks (including chromosomal abnormalities, gestational diabetes, and hypertension), the vast majority of people over 35 have healthy pregnancies and healthy babies. The term "geriatric pregnancy" is outdated and does not reflect reality. With appropriate prenatal care and monitoring, outcomes are excellent.

Amniocentesis Questions and Fears

Amniocentesis is a diagnostic test performed between 15-20 weeks that analyzes amniotic fluid to detect chromosomal conditions and genetic disorders with over 99% accuracy. The risk of pregnancy loss from the procedure is approximately 1 in 500-1,000 when performed by an experienced provider. Understanding the actual risks can help you make an informed decision.
