Have you ever slipped on your favorite pair of shoes only to find they suddenly feel too tight? Swollen feet can be uncomfortable, making even the simplest tasks—like walking—feel like a challenge. While swelling can happen due to minor issues, it can also be a sign of an underlying health condition. Understanding the causes and knowing when to seek medical attention can make all the difference in your well-being.
What Causes Swollen Feet?
Your body naturally fights gravity to circulate blood and fluids throughout your system. When something disrupts this process, fluid can accumulate in the feet, ankles, and legs—a condition known as edema. While occasional swelling may not be a major concern, persistent or painful swelling may signal a more serious issue.
Let’s take a look at 10 common causes of swollen feet and when to see your doctor.
1. Standing or Sitting for Too Long
If you’ve been on your feet all day—or, on the flip side, sitting for extended periods—your feet may swell. This happens due to gravity, which causes fluids to pool in your lower extremities.
How to Reduce Swelling:
- Elevate your feet at the end of the day
- Wear compression socks
- Take breaks to stretch or move around
If swelling doesn’t subside after rest or starts affecting one foot more than the other, it’s time to check with a doctor.

2. Excessive Salt Intake
Do you love salty snacks like chips, fries, or canned soups? Too much sodium can cause your body to retain water, leading to swollen feet and ankles.
Ways to Reduce Sodium Intake:
- Check food labels and opt for low-sodium options
- Increase potassium intake (bananas, spinach, avocados)
- Stay hydrated to flush out excess salt
Persistent swelling could indicate an issue with your kidneys or heart, so seek medical advice if lifestyle changes don’t help.
3. Injuries and Inflammation
A twisted ankle, fracture, or tendonitis can lead to swelling due to inflammation. The key difference between injury-related swelling and other causes? Pain.
Treatment for Injury-Related Swelling:
- Rest and avoid putting weight on the affected foot
- Apply ice packs to reduce inflammation
- Use compression bandages for support
If swelling worsens or doesn’t improve after a few days, consult a doctor.
4. Pregnancy
Pregnant women often experience swollen feet due to increased fluid retention, weight gain, and pressure on blood vessels.

Tips to Reduce Swelling During Pregnancy:
- Avoid standing for long periods
- Wear comfortable shoes and avoid tight socks
- Stay hydrated and elevate your feet
However, if swelling is sudden, severe, or accompanied by high blood pressure, it could be a sign of preeclampsia, a serious condition that requires medical attention.
5. Premenstrual Syndrome (PMS)
Hormonal changes before your period can cause bloating and fluid retention, leading to swollen feet.
How to Manage PMS Swelling:
- Reduce salt and processed foods
- Stay active and drink plenty of water
- Consider magnesium supplements to balance fluid levels
If swelling lasts beyond your menstrual cycle or worsens over time, speak to your doctor.
6. Excess Body Weigh
Carrying extra weight puts added pressure on your feet and blood vessels, leading to swelling.
Ways to Reduce Swelling from Extra Weight:
- Engage in low-impact exercises like swimming or cycling
- Maintain a healthy diet to support weight loss
- Elevate your feet periodically
Even modest weight loss can significantly reduce swelling and improve circulation.
7. Medication Side Effects
Certain medications can cause fluid retention, including:
- Blood pressure medications
- Steroids
- Antidepressants
- Diabetes medications
What You Can Do:
- Talk to your doctor about alternative medications
- Increase movement and hydration
- Use compression socks to prevent fluid buildup
Never stop a prescribed medication without consulting your doctor first.
8. Varicose Veins
Varicose veins occur when veins become weak and struggle to push blood back to the heart. This leads to blood pooling in the legs and feet, causing swelling.
How to Manage Varicose Veins:
- Exercise regularly to improve circulation
- Elevate your legs when sitting or lying down
- Wear compression socks
If swelling worsens or becomes painful, seek medical advice for further treatment options.
9. Blood Clots (Deep Vein Thrombosis – DVT)
A blood clot in your leg can block circulation, leading to one-sided swelling, pain, and redness. This condition—called deep vein thrombosis (DVT)—is potentially life-threatening if the clot travels to your lungs.
Seek Medical Help Immediately If You Experience:
- Pain and tenderness in one leg
- A warm sensation around the swollen area
- Shortness of breath or chest pain
Blood clots require immediate medical treatment, often with blood thinners or other interventions.
10. Heart, Liver, or Kidney Disease
Swelling in the feet can be an early warning sign of organ-related issues:
- Heart failure can cause fluid retention due to poor circulation
- Kidney disease reduces the body’s ability to remove excess fluids
- Liver disease leads to low protein levels, causing fluid buildup
When to See a Doctor:
- Swelling doesn’t go away after rest
- It affects both feet and worsens over time
- Symptoms include shortness of breath, fatigue, or nausea
Prompt medical attention is crucial to managing and treating these conditions effectively.
Final Thoughts: Don’t Ignore Persistent Swelling
Swollen feet can be a minor inconvenience—or a major red flag. If you notice persistent swelling, pain, or other concerning symptoms, don’t ignore them. While occasional swelling from standing, salty foods, or PMS is common, ongoing or severe swelling could point to a deeper health issue.
When in doubt, listen to your body and consult a doctor. Your feet might just be trying to tell you something important!
