We often overlook our feet, but they can reveal surprising clues about our health. As the article asks, “Could our feet be the windows to our overall health?”

**Swelling and Fluid Retention**
Swollen feet might point to serious conditions. “Heart failure can cause fluid buildup,” and kidney or liver problems—such as cirrhosis—can also lead to swelling due to fluid imbalance.

**Vein and Lymph Issues**
If your veins struggle to return blood to the heart, “fluid can pool in the legs and feet,” a condition known as venous insufficiency. Similarly, blocked lymph nodes may cause lymphedema, or chronic swelling.

**Infections**
Sudden swelling, pain, and redness in one foot may suggest an infection like cellulitis.

**Medication Side Effects**
Some drugs—including steroids, antidepressants, and blood pressure medications—may cause feet to swell.

**Pregnancy Warning Signs**
Swelling during pregnancy is common, but “excessive or sudden swelling can signal preeclampsia,” a potentially dangerous condition.

Taking a closer look at your feet might help detect hidden health issues early.
