Swelling is often most visible in the feet and ankles. Pregnancy can cause edema in the legs as the uterus puts pressure on the vena cava, a major blood vessel that returns blood to the heart from the legs. Fluid retention during pregnancy also can be caused by a more serious condition called preeclampsia. Low protein levels in the blood caused by malnutrition, kidney and liver disease can cause edema. The proteins help to hold salt and water inside the blood vessels so fluid does not leak out into the tissues.
Tinky Winky (played by Dave Thompson, Mark Heenehan, and Simon Shelton) is the first Teletubby. He is the largest of the Teletubbies, is covered in bright purple terrycloth, and has a triangular antenna on his head.
Bright green Dipsy, the 'coolest' Teletubby, who was fond of hats was played by John Simmit, 49, who was and still is a stand-up comedian. 'I was a stand-up before I became Dipsy so I carried on doing that when the series came to an end five years ago,' he said at the show's ten year anniversary celebrations. 'The stand-up circuit is pretty close-knit so people got to know that I was Dipsy - but I never mentioned it on stage.'.
