Swollen ankles during your period happen because hormonal fluctuations cause water retention and temporary blood vessel dilation. This menstrual-related swelling typically peaks during the luteal phase, when progesterone levels rise.
Progesterone slows fluid elimination by reducing sodium excretion through your kidneys. Estrogen increases blood vessel permeability, letting fluids leak into surrounding tissues. Both hormones peak during the luteal phase, making swelling most noticeable then.
| Type | Location | Timing |
|---|---|---|
| Mild edema | Feet, ankles, hands | Starts mid-cycle, peaks before period |
| Moderate swelling | Legs, abdomen, face | Lasts throughout luteal phase |
| Severe edema | Full-body | Persistent beyond period |
Most women experience mild-to-moderate swelling. Severe or persistent swelling may indicate an underlying condition like venous insufficiency or kidney disease.
