Sweating Question

[redoctober]

I understand that dry skin and sweating issues are symptoms of dysautonomia, but I'm a little confused about the relationship. I've noticed that the skin on my arms can get pretty wrinkly/flaky...like it is dehydrated. However, I can produce sweat like crazy in these same areas during a workout. So, if I can sweat like a pig on a particular patch of skin...how can it also be "dry and flaky" as well?

Here's a picture of my (really) sweaty arm that also sheds dry skin like no tomorrow:

oh, I'm envious of that sweating!! I can't sweat, thus NO heat tolerance.

I think sweating is independent of oil glands, so I'm thinking they are two separate entities. Someone correct me if I am wrong.

yes, you can have dry skin and sweat. I do not sweat either and I have to stay cool. Very scary not to sweat.

There are two functions of the small nerve fibers in your skin: vasomotor and sudomotor. The vasomotor nerves control the diameter of the blood vessels. The sudomotor nerves control sweating. Either one is an autonomic function. I have POTS and obvious discoloration of my arms or legs when they hang down, so I have vasomotor neuropathy. The sweat test is what tests for sudomotor neuropathy (and the QSART too, I think?).

I dont sweat either. Yesterday was terrible. First hot day this year. Was outside for a total of ten minutes. Not a drop of sweat on me. My sitting heart rate 125, all I did was stand up and went well over 160. Needless to say went inside and took a nap. Ugh!
