In focal (localized) sweating, the excessive sweating occurs either in the palms, soles, armpit (axilla) or face. It may occur on one or both sides of the body. The rest of the body acts normally and does not perspire. The most classic example of localized sweating is the axilla (armpit).
Axillary Hyperhidrosis (Armpit Sweating) is associated with excessive dripping sweating in the armpits. If the clothes are not frequently changes, an odor is always present. The amount of sweating is extremely difficult to control and does not respond to any deodorants and anti perspirants.
While the presence of axillary sweat and bromhidrosis (odor) is normal in most individuals after the age of puberty, some individuals experience excessive sweating that pours down the arms and soaks the clothes, creating a socially embarrassing situation. Because of the constant wetness and staining from the sweat, these poor individuals are not able to wear clothes of certain fabrics or colors.
The condition when severe can lead to social isolation and depression. It is always worsened in the presence of anxiety and stress.
Why localized sweating occurs in one part of the body is not known and is not associated with any other disorders. It appears that the sweat glands in these areas become hypersensitive or overactive than normal. Frequently, this condition may run in families but no genetic linkage factor has been identified. The condition can develop at any age but most individuals complain about the sweating in their late teens. Both men and women appear to be equally affected.
The condition does vary in severity with time. It is silent for some time and then starts up again. The sweating is usually worsened by stress, emotional lability spicy foods and heat. The sweating is always made worse by anxiety. In most cases the triggers of sweating remain unknown. The majority of individuals who develop this disorder are under the age of 25. The condition appears to occur in 3 out 100 people. It is a long term condition, however, a significant number of individuals to improve with time.
