Sweating is
embarrassing, it stains clothes, and it complicates business and social
interactions. Severe cases can have serious practical consequences as well,
making it hard for people who suffer from it to hold a pen, grip a steering
wheel, or shake hands. Neurologic, metabolic, and other systemic diseases can
sometimes cause excessive sweating, And this excessive sweating is known as
Hyperhidrosis.
Hyperhidrosis,
which is sweating in excess of that required for normal thermoregulation, is a
condition that usually begins in either childhood or adolescence. Although any
site on the body can be affected by it, the sites most commonly affected are
the palms, soles, and axillae. It may be idiopathic or secondary to other
diseases, metabolic disorders, febrile illnesses, or medication use. It exists
in 3 forms: emotionally induced Hyperhidrosis (in which it affects the palms,
soles, and axillae,[1, 2] localized Hyperhidrosis, and generalized
Hyperhidrosis. It often causes great emotional distress and occupational
disability for the patient, regardless of the form.
The sympathetic
nervous system controls the sweating throughout the body. Often there is no
identifiable cause, but excessive activity of the sympathetic nervous system is
believed to be responsible in the majority of those affected. The sympathetic
nervous system normally responds strongly in situations of fear or stress. The
involved nerves branch from the sympathetic chain within the chest cavity.
Through a
systematic evaluation of causes and triggers of excessive sweating, followed by
a judicious, stepwise approach to treatment, many people with this annoying
disorder can achieve good results and improved quality of life.
