What is hyperhidrosis?
Hyperhidrosis is a pathological condition characterised by excessive sweating by sweat glands.
Depending on the site affected, it is characterised as focal or generalised. Focal hyperhidrosis can be idiopathic (primary), related to neuropathies, or it may be a result of diseases and wounds that affect the sympathetic nervous system. Generalised hyperhidrosis is usually secondary. Endocrinological and metabolic disorders, such as diabetes, hypoglycaemia and menopause, as well as neurological disorders may be accompanied by generalised hyperhidrosis.
Which body areas are affected?
Primary hyperhidrosis usually affects the armpits, palms of the hands, soles of feet and the face.
There are several types of treatments for hyperhidrosis, including antiperspirant sprays and creams, iontophoresis (suppresses sweat glands using galvanic electrical current), surgical removalof thesweat glands, sympathectomy which disables the sympathetic nerves that stimulate the glands
The currently most effective treatment for hyperhidrosis is achieved with Botulinum toxin typeA infusion. With this botulinum toxin treatment, the nervous stimulus is interrupted. In this particular treatment for hyperhidrosis, Botulinum Toxin disrupts the nervous stimulus that reaches the sweat glands, instructing them to produce sweat.
It should be noted that the application of Botulinum Toxin A in such conditions prevents excessive sweating rather than normal sweat production. Nearly 90% of patients respond to treatment for an average period ranging from 7 to 8 months.
