Mrs. Oberhaus needs surgery to correct a severe case of Raynaud's disease, affecting one of her hands. What surgical procedure will be performed? After the surgery, will she be more likely to suffer from anhidrosis (lack of sweating) or hyperhidrosis (profuse sweating) in the affected hand?
What will be an ideal response?
Mrs. Oberhaus' doctor will perform a sympathectomy. Cutting the sympathetic fibers will result in dilation of the affected blood vessels. Because sweating is stimulated by sympathetic nerves, after they are cut the affected hand will suffer from anhidrosis.
