Classification

A first classification distinguishes between generalized and localized sweating. The first involves the whole body and is usually a consequence of other pathologies (very often infections, endocrinological or neurological disorders, cardiovascular pathologies and neoplasms) or of the use of certain drugs; however, as well as pathological mechanisms, it can be the result of the action of external factors such as to cause overheating of the skin (environmental, clothing and exercise). Localized hyperspiration is instead in most cases idiopathic (or essential), but sometimes it can be emotional (palmar-plantar or axillary), gustatory, olfactory, associated with disorders affecting peripheral innervation, Frey syndrome ( frequent phenomenon that occurs after total parotidectomy or interventions on the temporomandibular joint, characterized by hyperhidrosis and facial redness in the parotid region during meals) and other factors.

Primary idiopathic sweating is a more frequent disorder than the secondary form; generally it begins in childhood or adolescence and lasts throughout life. Anxiety and nervousness can aggravate or trigger a sweating attack, but only rarely is a real psychiatric disease present. It can more often manifest with palmar, axillary and plantar hyperhidrosis, while less frequently it can extend to the trunk and thighs; a combination of the various locations described above is very likely. The disorder can reveal itself with attacks of sweating or, less frequently, continuously; it can be caused by high ambient temperatures (and in these cases there is often an exacerbation in summer and an improvement in winter) or by emotional stress, but it can also occur without any apparent triggering cause.
