Why do my legs swell? Water retention or inflammation?

Swelling in the legs can happen for several reasons — the two most common being water retention and inflammation. While they may look similar, they have different causes and signs. Here’s how to tell the difference:

💧 Water Retention (Edema)

What it is:
Excess fluid builds up in the tissues, especially in the lower legs, ankles, and feet.

Common signs:

  • Legs feel heavy or puffy
  • Skin may look shiny or stretched
  • Swelling increases after standing or sitting for long periods
  • Leaves a dent when pressed (pitting edema)
  • Usually painless, but can feel tight or uncomfortable

Possible causes:

  • Standing or sitting too long
  • Hot weather
  • High salt intake
  • Hormonal changes (e.g., menstruation, pregnancy)
  • Kidney, liver, or heart issues
  • Side effects of medications (e.g., blood pressure meds, NSAIDs)

🔥 Inflammation

What it is:
The body’s immune response to injury, overuse, or a health condition (like arthritis).

Common signs:

  • Area is warm, red, and painful
  • Swelling is usually localized (e.g., one joint or part of the leg)
  • May have reduced mobility or stiffness
  • Often comes with an aching, burning, or sharp pain

Possible causes:

  • Arthritis (osteoarthritis, rheumatoid arthritis)
  • Injury or trauma (sprain, strain, fracture)
  • Infection
  • Autoimmune conditions
  • Gout or bursitis

Redness/WarmthUncommonCommon
SymmetryOften both legs equallyMay affect only one area
Pressing leaves dentYes (pitting)No or very mild

⚠️ When to See a Doctor:

  • Sudden, severe swelling
  • One leg is more swollen than the other
  • Swelling with chest pain or shortness of breath
  • Fever, redness, or signs of infection
  • Swelling that doesn’t improve with rest

📝 Final Tip:

  • For water retention, try reducing salt, staying active, and elevating your legs.
  • For inflammation, rest, ice, anti-inflammatory foods, or natural remedies may help.
  • If you’re unsure, a doctor can check with simple exams or blood tests to find the root cause.
