Visual scale for the quantification of<unk> <unk>  can either be generalized, or localized to specific parts of the body. Hands, feet, armpits, groin, and the facial area are among the most active regions of perspiration due to the high number of sweat glands (eccrine glands in particular) in these areas. When excessive sweating is localized (e.g. palms, soles, face, underarms, scalp) it is referred to as primary<unk>  or focal<unk> . Excessive sweating involving the whole body is termed generalized<unk>  or secondary<unk> . It is usually the result of some other, underlying condition. Primary or focal<unk>  may be further divided by the area affected, for instance, palmoplantar<unk>  (symptomatic sweating of only the hands or feet) or gustatory<unk>  (sweating of the face or chest a few moments after eating certain foods).<unk>  can also be classified by onset, either congenital (present at birth) or acquired (beginning later in life). Primary or focal<unk>  usually starts during adolescence or even earlier and seems to be inherited as an autosomal dominant genetic trait. It must be distinguished from secondary<unk> , which can start at any point in life. Secondary<unk>  may be due to a disorder of the thyroid or pituitary glands, diabetes mellitus, tumors, gout, menopause, certain drugs, or mercury poisoning. One classification scheme uses the amount of skin affected. In this scheme, excessive sweating in an area of 100 square centimeters (16 square inches) or more is differentiated from sweating that affects only a small area. Another classification scheme is based on possible causes of<unk> .
