What Causes Lower Back Pain in Females?

16/01/2026

Lower back pain is one of the most common health complaints among women, affecting daily routines, sleep quality, and overall well-being. If you’ve ever wondered what causes lower back pain in females, the answer isn’t always simple. Women experience unique physical, hormonal, and lifestyle factors that can trigger or worsen discomfort in the lower back.

From menstrual cycles and pregnancy to posture habits and sleeping positions, multiple elements may be at play. Understanding the root cause is the first step toward effective relief and long-term prevention.

Understanding Lower Back Pain in Women

Lower back pain refers to discomfort or stiffness in the area between the ribcage and pelvis. It can be light and happen sometimes or really bad and last a long time. In females, this pain often overlaps with reproductive health, hormonal changes, and musculoskeletal differences.

Some women experience sudden pain, while others deal with chronic discomfort that develops gradually. Identifying patterns—such as pain during sleep, periods, or physical activity—can provide valuable clues.

12 Common Reasons: What Causes Lower Back Pain in Females

1. Hormonal Changes During Menstrual Cycle

Hormonal fluctuations before and during menstruation can loosen ligaments and increase inflammation.

Why it happens:

Rise in prostaglandins causes muscle contractions
Ligaments around the pelvis become more flexible
Increased sensitivity to pain

This explains why many women feel lower back pain just before or during their periods.

2. Pregnancy and Postpartum Changes

Pregnancy significantly alters posture, weight distribution, and spinal alignment.

Key contributing factors:

Growing uterus shifts the center of gravity
Increased lumbar curve
Weakening of core and pelvic muscles

Even after childbirth, lingering muscle weakness can continue to cause pain if not addressed.

3. Poor Posture and Sedentary Lifestyle

One of the most overlooked answers to what causes lower back pain in females is posture-related strain.

Common habits include:

Sitting for long hours at a desk
Slouching while using mobile phones
Sitting without lumbar support

Over time, poor posture stresses spinal discs and muscles.

4. What Causes Lower Back Pain in Females While Sleeping?

Night-time back pain is especially frustrating and often linked to sleep habits.

Possible reasons include:

Unsupportive or worn-out mattress
Sleeping on the stomach
Poor pillow height affecting spinal alignment

Side sleepers without knee support may also strain their lower back during sleep.

5. Muscle Strain and Overuse

Daily activities like lifting groceries, housework, or sudden movements can strain muscles.

Women are more prone to:

Repetitive bending
Carrying children on one hip
Improper lifting techniques

Even small strains can accumulate into chronic lower back pain.

6. Core Muscle Weakness

The lower back relies heavily on abdominal and pelvic muscles for support.

When core muscles are weak:

The spine bears more load
Muscles fatigue faster
Posture worsens

This is common in women who don’t engage in regular strength training.

7. Gynecological Conditions

Certain reproductive health issues may present as lower back pain.

Examples include:

Endometriosis
Uterine fibroids
Pelvic inflammatory disease (PID)

In these cases, back pain may worsen during menstruation or prolonged standing.

8. Osteoporosis and Bone Density Loss

Women, especially after menopause, face a higher risk of osteoporosis.

Why it matters:

Bones become fragile
Minor fractures can cause pain
Spinal compression alters posture

Lower back pain may be an early warning sign.

9. Stress and Emotional Tension

Stress doesn’t just affect your mind—it also affects the body.

Chronic stress can cause:

Muscle tightening in the lower back
Reduced blood flow to muscles
Heightened pain perception

This mind-body connection is often underestimated.

10. Weight Gain and Obesity

Excess body weight increases pressure on the lumbar spine.

This can lead to:

Disc compression
Muscle fatigue
Poor posture

Weight gain during pregnancy or hormonal changes can amplify this effect.

11. Footwear Choices

High heels and unsupportive shoes alter posture and walking mechanics.

Over time, they:

Shift weight forward
Increase lumbar curve
Stress spinal joints

This is a subtle but real contributor to lower back pain.

As women age, spinal structures naturally wear down.

Common conditions include:

Degenerative disc disease
Arthritis
Spinal stiffness

These changes may develop slowly but lead to persistent discomfort.

When Lower Back Pain Should Not Be Ignored

Seek medical advice if lower back pain:

Lasts more than a few weeks
Worsens at night
Radiates to legs
Comes with numbness or weakness
Is associated with fever or unexplained weight loss

Early diagnosis helps prevent complications.
