Q: MY ANKLES have been swelling, what could be the cause? Can I do anything for the swelling?

A: Swelling of the ankles as a result of the buildup of fluid in the tissues is called oedema. The causes of such include various illnesses, medications and occasionally allergies. A combination of medications, exercise, diet and lifestyle adjustments is often used in its treatment. While oedema can occur in any part of the body, the most affected areas are the feet, ankles and (lower) legs.

Causes of oedema

  • Gravity pulls water down into your lower limbs. The pull of gravity is accentuated if you are sitting or standing in one spot for an extended period.
  • If the valves in the veins of your legs are not functioning properly, this often leads to fluid accumulating in your feet and ankles. n A range of medical conditions can result in a buildup of fluid in your lower limbs. Especially diseases affecting such organs as the heart, lungs, kidneys, liver and thyroid.
  • Certain pain, diabetes, high blood pressure medications, steroids and hormones can cause oedema.
  • Pregnancy often causes mild oedema.

This is only a problem if associated with high blood pressure and or protein in the urine.

  • Premenstrual fluid retention.
  • Diets high in salt can result in fluid retention and oedema of the feet and ankles.
  • Inadequately functioning lymphatic system as a result of damage, infection or cancer.
  • Other causes include allergies, injury, burns, clots in the veins of the legs, and reduced protein in the diet.

How do you know that you have oedema?

  • The feet and ankles look swollen.
  • Skin often looks shiny.
  • Difficulty seeing the veins or bones in the foot or around the ankle.
  • Applying pressure with your fingers to the swollen area leaves an indentation/ dimple (pitting).
  • The feet may feel heavy, and you may have difficulty walking.

What are the complications of untreated oedema?

  • Chronic ulcer (“sore foot”).
  • Difficulty walking.
  • Poor circulation.
  • Cellulitis (infection in the soft tissue).
  • Pain in the lower limbs.
