Idiopathic hyperhidrosis localized to certain areas of the body.
Secondary focal hyperhidrosis. This form of excessive sweating is similar to. in that it affects certain areas of the body such as the armpits, hands and feet. The only difference between the two is that primary sweating occurs for no apparent reason whereas secondary sweating develops from an existing medical condition. Treatment for secondary focal hyperhidrosis. It is important to determine if there is an underlying cause such as heart disease or respiratory failure before prescribing a course of treatment. INTRODUCTION. Hyperhidrosis (excessive sweating) is a common condition rarely due to significant underlying pathology that may have serious social, emotional, and professional consequences. The diagnosis and treatment of primary focal hyperhidrosis is reviewed here. Night sweats and menopausal hot flashes are discussed separately. (See Approach to the patient with night sweats and Menopausal hot flashes .). Primary focal hyperhidrosis is usually caused by a problem with the sympathetic nervous system. This is an involuntary part of your body’sautonomic nervous system which regulates a range of functions that are related to the ‘fight or flight’ response to stress. in which the affected person sweats excessively from their entire body. Primary excessive sweating is often defined as ‘primary focal hyperhidrosis’ because the sufferer loses excess amounts of sweat from particular (‘focal’) parts of the body such as the hands and feet. Hands, feet, armpits, and the groin area are among the most active regions of perspiration due to the high number of sweat glands in these areas. When excessive sweating is localized (e.g. palms, soles, face, underarms, scalp) it is referred to as primary hyperhydrosis or focal hyperhidrosis. Excessive sweating involving the whole body is termed generalized hyperhidrosis or secondary hyperhidrosis. It is usually the result of some other, underlying condition. Primary or focal hyperhidrosis may be further divided by the area affected, for instance palmoplantar hyperhydrosis (symptomatic sweating of only the hands or feet) or gustatory hyperhidrosis (sweating of the face or chest a few moments after eating certain foods). Unlike its counterpart, that is, generalized or secondary hyperhidrosis, it is idiopathic in nature or is not associated with an underlying condition. Typical regions of excessive sweating include the underarms, palms, soles, groin and craniofacial (face/scalp) areas. Focal hyperhidrosis is a condition characterized by excessive or profuse sweating in certain body regions. Primary focal hyperhidrosis. Primary focal hyperhidrosis is one of two types of excessive sweating in which the sufferer experiences sweat loss from specific areas of their body. This differs from. in which the affected person sweats excessively from their entire body. Primary excessive sweating is often defined as ‘primary focal hyperhidrosis’ because the sufferer loses excess amounts of sweat from particular (‘focal’) parts of the body such as the hands and feet. Idiopathic hyperhidrosis localized to certain areas of the body is called primary focal hyperhidrosis. Primary focal hyperhidrosis usually affects the axillae, palms, and soles. The condition may also affect other sites, such as the face, scalp, inguinal, and inframammary areas. The diagnosis and treatment of primary focal hyperhidrosis is reviewed here. Night sweats and menopausal hot flashes are discussed separately. (See Approach to the patient with night sweats and Menopausal hot flashes .). Localized Sweating: Primary Focal Hyperhidrosis. The most common cause of excessive sweating is called primary focal hyperhidrosis. This form of hyperhidrosis affects about 1% to 3% of the population, and usually starts in childhood or adolescence. 1 | 2 | 3 | 4.
