WHAT CAN I DO ABOUT... water retention

Swelling of the feet and ankles is called oedema. This occurs because fluid leaks out of blood vessels into the tissues in the feet and ankles.

“Generally, the veins in the legs transport tissue fluid back up towards the heart. But anything that interferes with this makes oedema worse,” says Dr Lee. “For example, standing or sitting for long periods, hot weather, or pressure on the veins in the pelvis, and in pregnancy.

“If your electrolyte balance is abnormal, possibly from too much salt in your diet, this can cause oedema.

“It can also be a feature of blood clots and other more serious illnesses.” To reduce oedema, elevate your legs, and avoid sitting and standing for long periods. Try to lose weight, as this reduces pressure on the veins.

Exercise regularly and eat a low-salt diet.

If your symptoms do not improve, it’s advisable to see your GP.
