What Is Relaxin?
Relaxin is a hormone linked to pregnancy that helps change connective tissue and joint support. The hormone affects ligaments and other soft tissues, especially around the pelvis. These changes can support the body as pregnancy progresses, but they do not mean that every joint is unstable or injured.

Key Takeaways About Relaxin
- Relaxin is a hormone, not a joint disorder.
- Its effects may include greater pelvic ligament flexibility.
- Relaxin is not the same as a ligament tear.
How Relaxin Works

Relaxin is released during pregnancy and affects connective tissue. Connective tissue includes ligaments, which help support joints. The hormone can make some tissues more flexible as the body adapts to pregnancy.

The hormone does not work like a pain reliever or a treatment. Its effects may be felt around the pelvis, lower back, or other areas that share support between the spine and hips. Pregnancy Chiropractic Care considers these changes when reviewing movement, posture, and comfort.
Relaxin is not measured by checking whether a single joint feels loose. A clinician looks at your symptoms, movement, and physical findings together. The same hormone can affect people in different ways, so one person may notice more change than another.

From the Arrowhead Clinic - Lithia Springs team
When we discuss Relaxin, we consider how pregnancy-related tissue changes may affect movement and comfort. We review posture, pelvic motion, and reported symptoms before choosing gentle care strategies. Our team treats Relaxin as part of the pregnancy picture, not as a diagnosis by itself.
Relaxin in Practice: A Real-World Example
A pregnant person may notice new pelvic pressure or lower-back discomfort while Relaxin affects connective tissue. During Pregnancy Chiropractic Care, the team reviews movement and posture to guide appropriate care.
