History of Excessive Sweating with Abnormal Clinical Findings on Physical Examination or Laboratory Tests in Adolescents with Hyperhidrosis* Isolated cases may have a number of underlying etiologies that are not covered by this list. The most common include the following: neuropathic disorders including diabetes mellitus, hypothyroidism, ataxia telangiectasia, anorexia nervosa/bulimia nervosa; inflammatory diseases including sarcoidosis; multiple myeloma; lymphoproliferative disease such as systemic lupus erythematosus (SLE); adrenal insufficiency due to Cushing’s syndrome or Addison’s disease; tuberculosis; drug reactions such as drug hypersensitivity reactions including antineoplastic agents also known as chemoablativeness syndromes or allergic hypersensitivities caused by antihistamines or vasoconstrictors used for treatment of allergies.
