Hypohidrosis is a disorder in which a person exhibits diminished sweating in response to appropriate stimuli. In contrast with

benign condition, the consequences of untreated hypohidrosis include hyperthermia, heat stroke and death.[1]
An extreme case of hypohidrosis in which there is a complete absence of sweating and the skin is dry is termed anhidrosis.

Causes

The causes are the following:[citation needed]

Medications

Physical agents

Dermatological

Neuropathic

Diagnosis

Sweat is readily visualized by a topical indicator such as iodinated starch (Minor test) or sodium alizarin sulphonate, both of which undergo a dramatic colour change when moistened by sweat. A thermoregulatory sweat test can evaluate the body’s response to a thermal stimulus by inducing sweating through a hot box ⁄ room, thermal blanket or exercise. Failure of the topical indicator to undergo a colour change during thermoregulatory sweat testing indicates hypohidrosis, and further tests may be required to localize the lesion.[citation needed]

Magnetic resonance imaging of the brain and ⁄ or spinal cord is the best modality for evaluation when the lesion is suspected to be localized to the central nervous system.[citation needed]

dermatological disorder. Biopsy results may reveal the sweat gland destruction, necrosis or fibrosis, in addition to the findings of the primary dermatological disorder.[citation needed

Management

The treatment options for hypohidrosis and anhidrosis are limited. Those with hypohidrosis should avoid drugs that can aggravate the condition (see "Medications", under

corticosteroids. Although an optimum dose and regime has not been established, pulse methylprednisolone (up to 1000 mg/day) has been reported to have good effect.[citation needed
