Anhidrosis (Hypohidrosis)

Anhidrosis/hypohidrosis is reduced/absent sweating, focal or generalized, from causes: systemic (heat stroke/dehydration), neurologic (autonomic neuropathy/spinal cord/HSV), skin (scleroderma/ichthyosis/burn scars), medications (anticholinergics), congenital (ectodermal dysplasia). Treatment: identify/treat cause (stop anticholinergics; treat autonomic neuropathy; skin disease); avoid heat exposure; hydration; cool environment; monitor heat stroke risk; educate on signs of overheating; follow-up dermatology/neurology/internal medicine.
