What is Excess Sweating?

Excess sweating, or hyperhidrosis, is a condition characterized by an abnormally high level of perspiration. It can occur in specific areas, such as the palms, feet, underarms, or face, or affect the entire body. This condition can be either primary (idiopathic), where no underlying cause is identified and it is often linked to overactive sweat glands, or secondary, where excessive sweating is a symptom of another medical condition, such as thyroid problems, diabetes, or infections. Excess sweating can significantly impact daily activities, self-esteem, and quality of life.

What Causes Excess Sweating?

This condition is caused by a combination of factors. These factors include:

Excess sweating can be caused by various factors:

  • Primary Hyperhidrosis: This is the most common type, where sweating is not related to any other medical condition. It often affects specific areas such as the palms, feet, underarms, or face.
  • Secondary Hyperhidrosis: This type is due to an underlying medical condition or medication. Conditions like thyroid disease, diabetes, infections, or menopause can cause excessive sweating.
  • Medications: Some drugs, including antidepressants or antipyretics, can lead to increased sweating as a side effect.
  • Hormonal Changes: Fluctuations in hormones, such as those during menopause or puberty, can contribute to excessive sweating.
  • Stress and Anxiety: Emotional stress or anxiety can trigger sweating, particularly in social situations or stressful environments.

Diagnosing excess sweating typically involves:

  • Medical History: A healthcare provider will review your medical history, including any symptoms, medications, and lifestyle factors.
  • Physical Examination: An exam may be conducted to assess the areas affected by sweating.
  • Tests: Depending on the suspected cause, tests might be conducted to rule out underlying conditions, such as thyroid function tests or glucose tests.
  • Sweat Tests: Specific tests like the starch-iodine test or gravimetric test can measure the severity of sweating and identify affected areas.
  • What Are the Treatment Options for Excess Sweating?
  • Treatment options vary based on the severity and underlying cause:
  • Antiperspirants: Over-the-counter or prescription-strength antiperspirants containing aluminium chloride can help reduce sweating.
  • Medications: Oral medications such as anticholinergics can help reduce sweating by blocking nerve signals to sweat glands.
  • Botox Injections: Botox injections can temporarily block the nerves that stimulate sweat glands, providing relief for several months.
  • Iontophoresis: This treatment uses a device to pass a mild electrical current through the skin to reduce sweating, particularly in the hands and feet.
  • Surgery: In severe cases, procedures such as sympathectomy, which involves cutting nerves that trigger sweating, or removal of sweat glands may be considered.

Yes, certain lifestyle changes can help manage symptoms:

  • Wear Breathable Fabrics: Opt for clothing made from natural fibres like cotton that allow the skin to breathe and wick away moisture.
  • Stay Hydrated: Drinking plenty of water can help regulate body temperature and reduce sweating.
  • Practice Stress Management: Techniques such as mindfulness, meditation, or yoga can help manage stress and reduce sweating related to anxiety.
  • Maintain Good Hygiene: Regular washing and the use of antiperspirants can help control odour and keep sweat in check.
  • Avoid Triggers: Identifying and avoiding foods, drinks, or situations that trigger excessive sweating can be beneficial.

You should see a doctor if:

  • Excessive Sweating Is Persistent: If sweating is ongoing despite trying home remedies or over-the-counter treatments.
  • It Affects Daily Life: When sweating interferes with daily activities, work, or social interactions.
  • There Are Other Symptoms: If sweating is accompanied by other symptoms like unexplained weight loss, fever, or pain, it could indicate an underlying medical condition.
  • You Have Concerns About Treatments: If you are considering medical or surgical treatments and need professional advice on the best options for your condition.
