My GP has agreed with me that my legs look like a cartoon and I am waiting to hear from my private endio (he is calling around 7). In the meantime here is a cut and paste jobby of an article I saw on the board:
In hypothyroidism there is a strong tendency for your body to produce excess mucin - basically a jelly-like substance (chemically - glycosaminoglycans, hyaluronic acid, etc.). These build up in your tissue and retain water.
The resulting swelling - oedema - is non-pitting and if you press with finger tips, it pushes straight back. There are only a few causes of this type of non-pitting oedema and hypothyroidism is probably the top of the list.
The word myxoedema describes this swelling with mucin - and is a term quite often used for hypothyroidism itself because it is such a distinctive feature.
Only proper treatment with adequate thyroid hormone resolves this. And it can take quite a long time for it all to return to normal.
Did any of you have water tablets and how quickly did the swelling go down please?
