Swollen Feet: Causes, Warning Signs, and When to Seek Medical Advice
Swelling in the feet is something many people experience at different points in life. While it may seem harmless or temporary, it can sometimes be a signal of an underlying health condition that requires attention. Understanding the potential causes and knowing when to seek professional help is important for protecting your overall well-being.
Why Do Feet Swell?
There are many reasons why swelling in the feet occurs. Some are minor and temporary, while others may point to medical concerns that should not be ignored.
1. Poor Circulation
One of the most common causes of swelling is reduced blood flow in the legs and feet. When circulation is impaired, fluid can build up, leading to puffiness or discomfort. This is often linked to conditions such as peripheral artery disease or long periods of inactivity.
2. Fluid Retention
The body sometimes retains excess fluid, a condition known as edema. This can happen due to prolonged standing, sitting for hours during travel, or certain dietary factors such as high salt intake. In some cases, fluid retention may be related to issues with the heart, kidneys, or liver.
3. Inflammation and Injury
Swollen feet may also result from inflammation caused by sprains, strains, or other injuries. Even minor injuries can trigger noticeable swelling, often accompanied by pain, bruising, or redness in the affected area.
4. Medical Conditions
Certain health conditions can cause swelling as a secondary symptom. These may include:
-
Diabetes – which can lead to circulation issues and fluid buildup.
-
Arthritis – joint inflammation may cause localized swelling in the feet or ankles.
-
Infections – bacterial or fungal infections can lead to redness, swelling, and tenderness.
5. Medications
Some prescription medications, including those for blood pressure, diabetes, or hormone therapy, may have side effects that cause fluid retention and swelling.
When Swelling Should Be Taken Seriously
Not all swelling is cause for alarm, but it is important to monitor symptoms closely. You should seek medical advice if swelling is:
-
Persistent and does not improve with rest or elevation
-
Accompanied by pain, redness, or warmth in the skin
-
Present in only one foot or ankle, which may signal a blood clot
-
Associated with shortness of breath or chest pain, which requires immediate medical attention
