Diagnosis and qualitative identification of hyperhidrosis

Hyperhidrosis is a dermatologic disease defined as excessive sweating that exceeds thermoregulatory needs, and is estimated to affect at least 4.8% of the population. The condition can be classified as either primary and idiopathic, or secondary due to an underlying medical condition or medication adverse event. Primary hyperhidrosis accounts for 93% of all cases. The diagnosis is partially determined and supported by objective quantitative tools, but is mainly identified by subjective accounts of patients regarding the extent of impact the excessive sweating has on their daily and general quality of life.
