The nails are also more likely to becomes detached more easily if they become damaged (onycholysis). Raynauds disease of the skin which is a reaction of the blood vessels to cold is also more common.
One effect is the reflexes are sluggish at returning to normal after being hit with the reflex hammer. This means that when you tap the Achilles tendon and get a reflex, then things are slower to return to normal if there is a a hypothyroidism.
