A skin disease that prevents one from sweating?

What is it called when you just don't sweat at all when you're hot, and instead you get all itchy, and when it's really bad, you just feel like you're going to faint?

did you by any chance have ETS surgery for sweat? dr's wont tell patients that androhidrosis is a side effect
Reply:Anhidrosis is when you don't sweat at all, or oligohidrosis, when you sweat very little. These conditions can sometimes be caused by medication too. In these cases, you could be prone to getting a heat stroke if you're too hot, so avoid being out in the sun, or over-exerting yourself, and drink lots of cold fluids to keep yourself from becoming too hot.
