Have you ever taken off your socks at the end of the day and noticed deep marks around your ankles? Or perhaps your shoes suddenly feel tighter, even though you haven’t changed your footwear.
For many adults over 60, swollen feet and ankles are a familiar problem. Sometimes the swelling appears after a long day of standing, sitting, or traveling. Other times, it seems to develop without any obvious explanation.
While occasional mild swelling may be harmless, persistent or unexplained swelling can sometimes be an early sign of an underlying health condition involving the heart, kidneys, veins, or other parts of the body.
The important question is knowing when swollen ankles are simply a temporary inconvenience and when they deserve medical attention.
Here’s what older adults should know about the possible causes, warning signs, and practical ways to manage swelling safely.
1. Why Do Feet and Ankles Swell as We Age?
Swelling in the feet, ankles, and lower legs is commonly called peripheral edema.
Edema occurs when excess fluid accumulates in the tissues.
Gravity naturally encourages fluid to collect in the lowest parts of the body, especially after prolonged sitting or standing.
As people age, several factors can make swelling more common, including reduced physical activity, changes in vein function, certain medications, and chronic medical conditions.
However, swelling should not automatically be considered a normal part of aging.
Understanding its cause is important because the appropriate treatment depends on what is producing the fluid buildup.
2. Poor Vein Function: A Common Cause of Swollen Ankles
One of the most common causes of chronic swelling in older adults is chronic venous insufficiency.
Inside the veins of your legs are small valves that help blood travel upward toward your heart.
When these valves weaken or become damaged, blood can pool in the lower legs, increasing pressure inside the veins and allowing fluid to leak into surrounding tissues.
Signs you may notice
- Swelling that becomes worse toward evening
- A heavy or aching sensation in the legs
- Visible varicose veins
- Brownish discoloration around the ankles
- Dry, itchy, or irritated skin near the lower legs
In more advanced cases, venous insufficiency can contribute to skin breakdown and difficult-to-heal ulcers.
What may help?
Walking, gentle calf exercises, avoiding prolonged immobility, and elevating the legs can sometimes reduce symptoms.
Compression stockings may also help certain people, but they should be properly fitted and used with medical guidance, especially if you have peripheral artery disease or other circulation problems.
3. Heart Problems: When Swelling May Be a Warning Sign
Swollen feet and ankles can sometimes be associated with heart failure.
Heart failure does not mean that the heart has stopped working. It means the heart is unable to pump or fill efficiently enough to meet the body’s needs.
This can contribute to fluid accumulation in the legs and other tissues.
Other symptoms to watch for
Swelling related to heart failure may occur alongside:
- Shortness of breath during ordinary activities
- Difficulty breathing while lying flat
- Waking at night feeling breathless
- Unusual fatigue or reduced exercise tolerance
- Rapid weight gain caused by fluid retention
Swelling alone does not establish a diagnosis of heart failure. Many other conditions can cause similar symptoms.
However, new or worsening swelling accompanied by breathlessness should be evaluated promptly.
Call 911 if you experience severe difficulty breathing, chest pain, fainting, or sudden severe symptoms.
4. Kidney Problems and Fluid Retention
Your kidneys play a major role in regulating fluid, sodium, and waste products in the body.
When kidney function becomes impaired, the body may retain excess salt and water, contributing to swelling.
Certain kidney disorders can also cause protein to leak into the urine. A significant loss of blood proteins can allow fluid to accumulate in the tissues.
Possible accompanying symptoms
Depending on the underlying kidney condition, you might notice:
- Puffiness around the eyes
- Swelling in the feet or legs
- Changes in urination
- Foamy urine caused by excess protein
- Fatigue or reduced appetite
Importantly, chronic kidney disease often develops without obvious symptoms during its earlier stages.
People with diabetes or high blood pressure have an increased risk of kidney disease.
If kidney problems are suspected, a healthcare professional may recommend blood tests, urine tests, and an assessment of kidney function.
5. Could Your Medications Be Causing the Swelling?
Some medications commonly prescribed to older adults can cause swelling in the feet and ankles.
This does not necessarily mean the medication is dangerous or should be stopped.
Instead, swelling may be a recognized side effect that needs to be discussed with the prescribing clinician.
Medications that may contribute
Examples include:
- Certain calcium channel blockers used for high blood pressure, particularly amlodipine
- Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and naproxen
- Corticosteroids
- Certain diabetes medications, including pioglitazone
- Some medications used for nerve pain, including gabapentin and pregabalin
If swelling begins after starting a new medication or changing a dose, inform your healthcare professional.
Never stop or adjust a prescribed medication without medical advice.
Sometimes a dosage adjustment or a different treatment can improve the swelling.
6. Swelling in One Leg: Why It Needs Special Attention
Swelling that affects only one leg can have different causes from swelling that affects both legs.
One important possibility is deep vein thrombosis (DVT), a blood clot that forms in a deep vein, often in the leg.
DVT can occur after prolonged immobility, surgery, hospitalization, or long-distance travel. Risk also increases with certain medical conditions and advancing age.
Warning signs of DVT
Possible symptoms include:
- New swelling in one leg
- Pain or tenderness in the calf
- Warmth in the affected area
- Redness or unusual skin discoloration
Not everyone with DVT experiences all these symptoms, and some people have few obvious warning signs.
A blood clot can become life-threatening if part of it travels to the lungs, causing a pulmonary embolism.
Seek urgent medical assessment for new, unexplained one-sided leg swelling, particularly if it is painful, warm, or red.
If swelling is accompanied by sudden shortness of breath, chest pain, coughing blood, or fainting, call 911 immediately.
Do not massage a leg when DVT is suspected.
7. Liver Disease and Low Blood Protein
Although less common than venous problems, advanced liver disease can also contribute to fluid retention.
The liver produces albumin, an important protein that helps keep fluid inside blood vessels.
Severe liver disease may reduce albumin production and alter the body’s regulation of salt and water.
This can lead to fluid buildup, particularly in the abdomen and sometimes in the legs.
Other possible symptoms include yellowing of the skin or eyes, abdominal swelling, easy bruising, and fatigue.
However, swollen ankles alone are not a reliable indication of liver disease.
A medical evaluation is necessary to determine whether the liver is involved.
8. Lymphedema: When the Lymphatic System Is Involved
The lymphatic system helps return excess fluid from body tissues to the bloodstream.
When lymphatic drainage is disrupted, fluid can accumulate and cause swelling known as lymphedema.
This condition may develop after certain cancer treatments, surgery, infections, or other causes of lymphatic damage.
Sometimes the cause is not immediately clear.
Lymphedema can cause persistent swelling, a feeling of heaviness or tightness, and gradual changes in skin texture.
Treatment may include specialized compression, exercise, skin care, and lymphatic therapy under professional supervision.
Persistent swelling should be assessed rather than assumed to be lymphedema.
9. Simple Daily Habits That May Help Reduce Swollen Feet
If a healthcare professional has ruled out urgent or serious causes, several everyday habits may help manage mild swelling.
The most effective approach depends on the underlying condition.
Elevate your legs
When resting, try raising your legs above heart level for approximately 15–20 minutes, if comfortable and medically appropriate.
This can help gravity move accumulated fluid away from the feet and ankles.
People with certain heart or breathing conditions should ask their clinician whether this position is suitable.
Keep moving throughout the day
Sitting or standing in one position for long periods can encourage fluid accumulation.
Gentle movement activates the calf muscles, which help push blood upward through the veins.
Simple activities include walking around the house, ankle circles, and gently moving the feet up and down while seated.
Be mindful of sodium intake
Excess dietary sodium can contribute to fluid retention, particularly in people with heart, kidney, or certain other medical conditions.
Common sources include processed meats, canned soups, packaged snacks, and restaurant meals.
Choosing lower-sodium alternatives may help, depending on your medical needs.
Wear comfortable footwear
Shoes that are too tight can increase discomfort when feet are swollen.
Choose supportive footwear with enough room for the toes and avoid socks that create excessive pressure around the ankles.
Ask about compression stockings
Properly selected compression stockings may improve swelling caused by certain venous conditions.
However, compression is not appropriate for everyone. People with significant arterial disease or certain forms of heart failure may require special precautions.
Avoid purchasing very tight compression garments without knowing the cause of your swelling.
Don’t take water pills without medical advice
Diuretics, sometimes called water pills, are useful for specific medical conditions, including some cases of heart failure.
But they are not a universal treatment for swollen ankles.
Taking them unnecessarily can cause dehydration, electrolyte disturbances, or kidney problems.
10. When Should Swollen Feet or Ankles Concern You?
Not every episode of swelling requires emergency care, but certain symptoms should never be ignored.
Call 911 immediately if swelling occurs with:
Severe or sudden difficulty breathing, chest pain, fainting, or coughing up blood. These symptoms may indicate a life-threatening condition.
Seek urgent medical assessment if:
One leg suddenly becomes swollen, painful, warm, or red, or swelling develops rapidly without an obvious explanation.
Schedule a medical appointment if:
Swelling persists, repeatedly returns, gradually worsens, or is accompanied by skin discoloration, fatigue, or unexplained weight changes.
11. What Tests Might Your Doctor Recommend?
When evaluating swollen feet and ankles, a healthcare professional will usually begin by asking when the swelling started, whether it affects one or both legs, and whether it changes throughout the day.
They may also review your medications and examine your heart, lungs, legs, and skin.
Depending on your symptoms, tests may include:
- Blood tests: To assess kidney function, liver function, albumin levels, and other possible causes.
- Urine tests: To look for protein loss or signs of kidney disease.
- Venous ultrasound: To investigate suspected blood clots or problems with vein function.
- Echocardiogram: To evaluate heart structure and function when heart disease is suspected.
- Other heart tests: Such as an electrocardiogram or blood tests when clinically appropriate.
Not everyone needs all these investigations. Testing should be guided by the symptoms and examination findings.
12. Can Swollen Ankles Be Prevented?
Some causes of swelling cannot be completely prevented, especially when they are related to chronic medical conditions.
However, maintaining regular physical activity, avoiding prolonged immobility, managing blood pressure and diabetes, and following prescribed treatment plans can help reduce certain risks.
For older adults who spend much of the day seated, regular movement breaks may be particularly beneficial.
It’s also useful to notice patterns.
Does the swelling appear only in the evening? Does it improve overnight? Did it begin after a medication change? Is one leg more swollen than the other?
These observations can provide valuable information to your healthcare professional.
Final Thoughts: Your Feet May Be Telling You Something Important
Swollen feet and ankles are common after 60, but they should not automatically be dismissed as an unavoidable consequence of getting older.
Sometimes the explanation is relatively simple, such as prolonged sitting, standing, or a medication side effect.
In other cases, swelling may be associated with venous insufficiency, kidney disease, heart failure, blood clots, or problems with the lymphatic system.
The most important thing is to pay attention to swelling that is new, persistent, worsening, or accompanied by other symptoms.
Early evaluation can help identify the underlying cause and guide appropriate treatment.
And remember, the goal is not simply to make the swelling disappear. It’s to understand why it developed in the first place.
Have you ever noticed swollen feet or ankles at the end of the day? Does the swelling improve after resting overnight?
