For people living with diabetes, unusual foot swelling should never be ignored.
What Causes One Foot to Swell More Than the Other?
1. Deep Vein Thrombosis (DVT)
Deep vein thrombosis occurs when a blood clot forms in a deep vein, usually in the leg. It may cause swelling in one leg, pain, tenderness, warmth, or redness. DVT can be serious and requires urgent medical assessment.
2. Infection in the Foot
A foot infection may cause swelling, redness, warmth, pain, or discharge from a wound. In people with diabetes, nerve damage can reduce the ability to feel pain, meaning an injury or infection may go unnoticed.
3. Injury or Sprain
An ankle sprain, fall, or other injury can damage the surrounding tissues and cause localized swelling. If swelling is severe, pain is significant, or walking becomes difficult, seek medical evaluation.
4. Circulation Problems
Poor blood circulation can affect the feet and legs. Conditions involving the veins or arteries may contribute to swelling or other changes in foot health. The cause should be assessed by a healthcare professional.
5. Fluid Buildup and Other Medical Conditions
Fluid can accumulate in the tissues for several reasons, including certain medications and heart, kidney, or vein-related conditions. Although these conditions often affect both legs, swelling can sometimes be uneven.
Why Is Foot Swelling Important for People With Diabetes?
Diabetes can affect nerves, circulation, and the body's ability to heal wounds. Swelling may be associated with infection, injury, or other foot complications.
Watch for these warning signs:
✓ Redness or unusual warmth
✓ A wound, blister, or discharge
✓ New changes in foot shape
✓ Skin discoloration
✓ Swelling that persists or gets worse
✓ Reduced sensation or difficulty walking
A warm, swollen foot in someone with diabetes may sometimes indicate Charcot foot, a condition involving damage to the bones and joints. Prompt assessment is important, even if the foot is not very painful.
✓ When Should You Seek Medical Attention?
Seek urgent medical assessment if one leg or foot suddenly becomes swollen, especially when accompanied by pain, redness, or warmth.
Call emergency services immediately if swelling occurs with chest pain, sudden breathlessness, or coughing up blood, as these may indicate a serious blood clot complication.
People with diabetes should also seek prompt assessment for a newly swollen, red, or warm foot, particularly if there is a wound or skin discoloration.
How Can You Help Protect Your Foot Health?
✓ Inspect your feet daily for swelling, wounds, blisters, or changes in colour.
✓ Wear properly fitting footwear.
✓ Keep your feet clean and dry.
✓ Avoid walking barefoot, especially if you have reduced sensation.
✓ Do not ignore wounds or changes in foot temperature.
✓ Seek professional advice for unexplained or persistent swelling.
Avoid self-diagnosing the cause or massaging a suddenly swollen leg when a blood clot is possible. The appropriate treatment depends on the underlying condition.
✓ Conclusion
One foot being more swollen than the other can have several causes, ranging from injury to infection or a blood clot. Identifying the cause early is important, particularly for people with diabetes. Do not ignore sudden, persistent, or worsening swelling.
