Swollen feet
This is usually a temporary nuisance caused by standing too long or a long flight - especially if you are pregnant.
In contrast, feet that stay swollen can be a sign of a serious medical condition. The cause may be poor circulation, a problem with the lymphatic system, or a blood clot. A kidney disorder or underactive thyroid can also cause swelling.
If you have persistent swelling of your feet, see a physician.
