My legs swell even if im not on them for long periods of time. i do not eat lots of salt or faty. greasy foods. what else could be my cause?

Pregnancy: Varicose or incompetent veins, lymphedema to name a few. There is also the possibility of fibroids causing an issue, even kidney or cardiac issues. See your family doctor.

Swelling of legs: swelling of legs for no resin should be taken not lightly unless you stand whole day SO see a internist or kidney md

Edema: Hi. There are 4 main organs systems that, when dysfunctional, cause edema: heart, lungs, kidneys, liver. There are also some circulatory problems that cause edema. You should see your doctor for a thorough evaluation. Some problems are effectively treatable. Good luck!
