Hyperhidrosis is the name for a condition characterized for the excess of sweating, this condition is caused by a failure of the sympathetic nervous system producing more sweating than the amount required to equilibrate overall temperature. It mainly affects areas such as armpits, palms of hands, face & soles of the feet; this syndrome implies an intense alteration of the psychological state of the person & makes more difficult social interaction, for this reason many people affected by this syndrome see how their quality of life is affected & feel they are losing control over it since sweating can emerge independently from the temperature of the body or the mood of the person.
