Sodium is known to raise blood pressure (and sometimes greatly), so doctors generally recommend limiting it. Check with your healthcare professional before you up your intake -- if you consume an amount that's not good for you, it can lead to heart failure (especially if you're older).
Other possible causes for foot, leg, and ankle swelling include certain medical conditions or body changes, such as: Natural hormonal changes: Fluctuating levels of estrogen and progesterone can cause reduced circulation in the legs, resulting in swelling.
Swollen legs feet and ankles are caused by water retention. When your circulation has problems working against the effects of gravity, your blood collects in the lower part of your body. The extra pressure on your blood vessels makes them leak fluid into the tissues of your legs feet and ankles. This causes swelling, and your skin can become very discoloured; in severe cases your skin may even weep fluid. Large veins on the surface can become swollen and painful â a condition known as varicose veins.
