|Sweating is a natural process by which body regulates an individual’s body temperature. The system that regulates all this is known as Sympathetic Nervous system.In approximately 1% of the population this system is working at a higher level and thus this problem of Hyperhydrosis.
We divide hyperhydrosis into Two types: Idiopathic – of which the cause is unknown and the second one is secondary to some disease process.
Causes of Secondary Hyperhydrosis
This is a far more frequent condition than secondary hyperhydrosis and is generally, localized in one or several locations of the body (most often hands, feet, armpits or a combination of them). It usually starts during childhood or adolescence and persists all life. Nervousness and anxiety can elicit or aggravate sweating, but psychological/psychiatric disturbances are only rarely the cause of the disorder.
Sweating can appear suddenly or manifest itself more continuously.
In patients with primary hyperhidrosis or for symptomatic treatment of heavy sweating in patients with secondary hyperhidrosis, not treatable otherwise, the following methods have been adopted.
Aluminium chloride (20-25%) in 70-90% alcohol, applied in the evening Alternate days.
This method consists in applying low intensity electric current (15-18 mA), supplied by a D/C generator, to the palms and/or soles immersed in an electrolyte solution. It is difficult to apply in axillary, and impossible to use in diffuse hyperhidrosis of the face or the trunk/thigh region.
There are no specific drugs available against profuse sweating. Sedatives or Anticholinergics are often tried. Anticholinergics show too many side effects.
Patients with axillary hyperhidrosis who are unresponsive to medical therapy can be effectively treated by excision of the axillary sweat glands.
The principle of sympathectomy is to interrupt the nerve tracks which transmit the signals to the sweat glands.
The endoscopic technique is very safe, if performed by a surgeon experienced in this type of procedure, leads to definitive cure in nearly 100% of patients, leaving only a minimal scar in the armpit.
Individuals with combined hyperhydrosis of the palms and soles have a good chance to improve the sweating of their feet after an operation aiming to suppress sweating of the hands. Isolated plantar hyperhydrosis can, however, only cured by Lumbar Sympathectomy, an open abdominal procedure.
Diffuse hyperhydrosis of the trunk or general sweating of the whole body cannot be treated by surgery.
OTHER TREATMENT METHODS
A family of toxins produced by bacteria known as Clostridium botulinum. This toxin is one of the most lethal poisons known, interfering with the effect of the transmitter substance acetylcholine at the synapses (the contact point of a nerve ending with another nerve cell or a muscle) and leading to progressive paralysis of all muscles in the body, including the respiratory muscles.
