It sounds like you’re referring to the small indentations that some people have on the lower back, just above the buttocks. Medically, these are often called “dimples of Venus” (in women) or sacral dimples (more general term).
Here’s what they usually mean:
1. Cosmetic or Normal Variation
- Most of the time, these dimples are completely normal and purely a cosmetic feature.
- They are caused by a short ligament attaching the skin to the pelvis (sacrum).
- Many people have them and they don’t indicate any health problem.
2. Potential Medical Significance
- Rarely, if a dimple is deep, unusually large, or accompanied by a tuft of hair, redness, or swelling, it could signal an underlying spinal issue, like a spinal defect or tethered cord.
- In babies, sacral dimples are sometimes checked to rule out congenital spinal problems.
3. Fun Facts
- “Dimples of Venus” are considered a sign of genetic and structural symmetry in the pelvis.
- They have no effect on health, strength, or flexibility.
Bottom line:
If they are small, shallow, and symmetrical, these two holes/dimples are just a natural feature. If there are unusual changes, pain, or other symptoms, it’s worth a medical check.
If you want, I can explain why some people think these dimples are linked to “good health or fitness”—it’s actually partly true! Do you want me to?
