By Mayo Clinic staffSome people will try almost anything to keep from perspiring, including Botox injections and surgery to remove overactive sweat glands. But for people with anhidrosis (sometimes called hypohidrosis), the inability to sweat normally can be life-threatening. When you don't perspire, your body can't cool itself, leading to overheating and sometimes to heatstroke — a potentially fatal condition.
Anhidrosis can be difficult to diagnose. Mild anhidrosis often goes unrecognized, and dozens of factors can cause the condition, including skin trauma and certain diseases and medications. Treatment of anhidrosis involves addressing the underlying cause, though in some cases, the reason for anhidrosis is never found.
