The president's recently discovered vein condition is called chronic venous insufficiency, which occurs when leg veins fail to pump blood to the heart, causing it to pool in the lower limbs, which can then become swollen.
Veins and valves "propel the blood up and out of the leg" and back toward the heart, Dr Meryl Logan, assistant professor of vascular surgery at the University of Texas at Austin told the BBC.
Blood flowing from the legs to the heart is moving against gravity, which can make that process more difficult.
"So what chronic venous insufficiency is, is when those veins and valves don't work and blood goes backwards down the legs," she said.

Leavitt said that there was "no evidence of deep vein thrombosis or arterial disease" and that all results from the test were "within normal limits".According to a note from White House physician Sean Barbabella released to reporters, the condition is "benign and common", especially in people over age 70.
Additional testing showed "no signs of heart failure, renal impairment, or systemic illness" in Trump, Barbabella said in the note, which confirmed the information from Leavitt's earlier briefing.
Overall, Trump is in "excellent health", the doctor wrote. Ah so. I believe the Queen died from just the same condition.
