Why does someone in shock exhibit diaphoresis

Why does someone in shock exhibit diaphoresis

Someone in "shock" will be having multiple organs fighting for blood flow, attempting to keep the blood pressure up and keep oxygen traveling to these organs.

Thus there will be a high level of epinephrine and other related hormones ("adrenalin", or part of the sympathetic nervous system) to counteract the shock. With the stimulation of the sympathetic nervous system with this outpouring of epinephrine, it will activate the sweat receptors in the skin, causing "diaphoresis", or excessive sweating.

ICD-10 Diagnosis Code F40.290 Androphobia
If you become anxious and extremely self-conscious in everyday social situations, you could have a social phobia. Agoraphobia is a fear of public places, and claustrophobia is a fear of closed-in places.

Stimulation of the sympathetic nervous system by any cause will cause sweating, and drugs such as cocaine and amphetamines, or disorders of the sympathetic nerves themselves, such as "reflex sympathetic dystrophy" cause excessive sweating.

Your grandson, is correct, in thinking "why is this happening", since the body hold onto fluids at this crucial time, but that's why he is trained to start two large-bore IVs in the field and Start crystalloid fluids, usually ringer's lactate or normal saline at a fast rate to make sure the blood pressure and fluid status remains optimal before they can get the patient to the hospital.
