If You Have These Two "Dimples" on Your Lower Back, Here's What They Mean

Purely cosmetic—a normal variation in anatomy
More visible in lean individuals or those with strong glutes/core
Genetic—some people simply have the right bone structure and skin elasticity for them to show

They do not indicate weakness, injury, or poor health—in fact, they’re often associated with good posture and pelvic alignment.

⚠️ When to Be Concerned: Rare Red Flags

While most sacral dimples are benign, certain types of dimples in the lower back—especially in infants or if accompanied by other symptoms—can signal spinal issues:

1. Atypical Sacral Dimples (in babies)

Located off-center, larger than 5mm, or deeper than normal
Found below the gluteal crease (not at the top)
Accompanied by hair tufts, skin tags, or discoloration
→ May indicate spina bifida occulta or tethered cord syndrome (requires pediatric evaluation).

2. Painful or Changing Dimples (in adults)

If dimples are new, asymmetrical, or associated with:
- Chronic lower back pain
- Numbness/tingling in legs
- Bladder/bowel dysfunction
  → Could relate to sacroiliac joint dysfunction, piriformis syndrome, or nerve compression.

🚩 Note: The classic “dimples of Venus” are painless, symmetrical, and present since adolescence. If yours fit this description—you’re perfectly fine!

❤️ The Bottom Line

For the vast majority of people, those two little indentations are a harmless—and even celebrated—part of human anatomy. They’re not a sign of anything wrong; if anything, they reflect your unique bone structure and body composition.
