Swollen Feet Can Have Many Causes. Here Are Nine Signs That May Be Worth Paying Attention To.

The feet can be affected, and symptoms may include pain, stiffness, warmth, and swelling.

But rheumatoid arthritis, osteoarthritis, gout, bursitis, infections, tendon injuries, and circulation disorders are fundamentally different conditions.

That is precisely why treating every swollen foot as though it has the same cause can be problematic.

A correct diagnosis guides the appropriate treatment.

Yet even this does not cover all of the common explanations for lower-leg swelling.

The Veins Can Play a Major Role
Chronic venous insufficiency can cause swelling when veins in the legs have difficulty returning blood efficiently toward the heart.

Veins contain valves that help keep blood moving in the proper direction. When these valves do not work effectively, blood can pool in the lower extremities and contribute to swelling.

People may notice that swelling becomes more apparent after spending considerable time standing.

But venous problems are only one possibility.

Kidney disease can contribute to edema because the kidneys play an essential role in controlling fluid and salt balance. Liver disease can also lead to abnormal fluid accumulation.

Certain medications can contribute as well.

This creates an important practical lesson: when swelling begins after starting or changing medication, the medication history may be relevant to a healthcare professional.

Patients should not stop prescribed medication on their own simply because swelling appears. Instead, they should discuss the change with the professional who manages their treatment.

Pregnancy and Swelling
Swelling can also occur during pregnancy.

However, sudden or severe swelling during pregnancy should not automatically be dismissed as a normal pregnancy symptom. A healthcare professional may need to assess the person and determine whether further evaluation is required.

The same general principle applies throughout this topic.
