Hyperhidrosis (Excessive Sweating)

Hyperhidrosis (Excessive Sweating)

Hyperhidrosis is a medical condition characterized by excessive sweating beyond what is necessary for thermoregulation. This condition can affect various parts of the body, including the palms, soles, underarms, face, and other areas. Excessive sweating can significantly impact daily activities and quality of life. There are two types of hyperhidrosis:

Primary (focal) hyperhidrosis:

  • Cause: Often has no identifiable underlying cause and tends to run in families, suggesting a genetic component.
  • Symptoms: Typically affects specific areas like the hands, feet, underarms, and face.
  • Onset: Usually begins in childhood or adolescence.

Secondary (generalized) hyperhidrosis:

  • Cause: Results from an underlying medical condition or is a side effect of certain medications.
  • Symptoms: Sweating occurs over larger areas of the body or the entire body.
  • Onset: Can start at any age and is often linked to conditions such as diabetes, thyroid problems, infections, or menopause.


  • Visible sweating that can soak through clothing.
  • Sweating that interferes with daily activities such as holding a pen, gripping a steering wheel, or shaking hands.
  • Skin infections or irritation due to excessive moisture.


  • A healthcare provider may perform a physical examination and take a detailed medical history.
  • Tests such as the starch-iodine test or thermoregulatory sweat test can help determine the severity and location of the sweating.
  • Blood tests may be conducted to rule out underlying conditions causing secondary hyperhidrosis.


  • Antiperspirants containing aluminum chloride.
  • Oral medications such as anticholinergics, beta-blockers, or benzodiazepines.
  • Botox injections: Effective for treating excessive sweating in specific areas like the underarms.
  • Surgery: In severe cases, options like sympathectomy (cutting nerves that trigger sweating) or sweat gland removal may be considered.
  • Lifestyle changes such as wearing breathable fabrics, maintaining good hygiene, and avoiding triggers like spicy foods or stress.
