I noticed my skin was getting very dry, rubbing my shins the floor looked like an advert for dandruff shampoo. Looking around the net for reasons/solutions I came across this site.
Thought it was very informative for anyone interested.
An underactive thyroid may result in:
Cold, pale and dry skin
Delayed wound healing
A yellowish hue to the skin due to carotenaemia
Sparse, brittle hair which comes out in handfuls
Slow growing ridged and brittle nails
Myxoedema resulting in puffy eyelids and hands – another presentation of mucinosis.
Thyrotoxicosis results in an increase in metabolic rate. This may result in:
Smooth, moist, warm skin
Flushing of face and hands
Overgrown nails (acropachy, clubbing), which may lift off the nail bed (onycholysis)
Fine soft thinned scalp hair
Generalised itching (pruritus)
Increased skin pigmentation
Graves disease can be associated with other autoimmune conditions, including vitiligo.
Pretibial myxoedema or thyroid dermopathy affects 5% of patients with Graves disease. It may appear before, during or after the thyrotoxic state and is sometimes associated with an underactive thyroid. Pretibial myxoedema presents with a swollen and lumpy appearance over the shins and sometimes also affects the feet. The skin may be discoloured pink or purple, with prominent hair follicles. This is known as ‘peau d'orange’ (orange-peel) appearance. It may instead look warty or ‘verrucous’.
