Hyperhidrosis
Hyperhidrosis: excessive sweating. I am going to focus on the hands, feet, and armpits because that is embarrassing and emotionally distressing to people who have it. It is thought less than 1% of the population suffers from this.
The cause? For most there is not a disease causing it. Those with growth hormone excess (acromegaly) have sweating hands and feet. Medications can cause it – there are a lot, in particular some NSAIDs, BP meds, migraine meds, antidepressants, and narcotics. Stimulants in particular can cause sweaty hands and feet because the sympathetic nervous system causes the sweat glands to secrete perspiration. Interesting: doesn’t occur when asleep. Episodes occur usually during stress or excitement. Of course heat can cause the sweating as well.
