title: Raynaud's phenomenon in hypothyroidism.
abstract: Two patients with Raynaud's phenomenon were found to be hypothyroid and their symptoms disappeared with thyroid replacement therapy. Vascular reactivity studies in one patient demonstrated decreased vasomotor tone after therapy. Raynaud's phenomenon may be an expression of altered autonomic function in hypothyroidism.
