Hypohidrosis

• Hypohidrosis is a condition in which a person
  loses his ability to sweat even in hot and humid
  conditions. Our body releases the heat in the
  form of sweating. The inability of the body to
  sweat due to Hypohidrosis often increases the
  amount of heat in the body. This overheating can
  result in fatal heat stroke and other
  serious sweat gland complications. Hypohidrosis
  can affect smaller or larger areas of the body.
  Most people are not aware that they are suffering
  from Hypohidrosis. If left untreated,
  Hypohidrosis can lead to the development of
  another serious condition known as Anhidrosis
  which results in complete absence of sweating.

  For detecting the amount of sweat produced from
  the patients body in response to a given
  stimulus.
• Tissue biopsy - Taking the sample of the affected
  tissue from the sweat gland and observing it
  under the microscope.
• Thermoregulatory test - In this test, sweat
  production is measured by exposing the skin to an
  increased temperature. The alizarin powder is
  sprinkled, which changes its color from purple to
  orange if sweat appears.
