excessive perspiration, disposition to perspire. In healthy persons hyperhidrosis may be observed when there is a high environmental temperature as one of the mechanisms of thermoregulation and with increased physical exertion. General hyperhidrosis may be observed in some endocrine diseases, various infections and intoxications, and also in affection of the hypothalamic region of the brain. Localized hyperhidrosis (for example, sweatiness of the palms, feet, and armpits) may be a function of increased excitability of the nervous system. Hyperhidrosis predisposes one to catarrhal diseases, pustulous and fungal infections (penetration of causative agents through the fragile surface layer of the skin), and friction irritations.
Treatment consists in removal of the cause of hyperhidrosis, hygienic body maintenance, general supporting treatment, sometimes physiotherapy, and topical antiseptic and adsorbent medications.
