Excessive sweating on the palms and soles is known as Primary Focal Hyperhidrosis. Since you've had this for years and it's not a recent development, it is likely a localized overactivity of your sweat glands rather than an underlying systemic illness. For your upcoming medical examination, the focus is usually on whether the condition interferes with your functional abilities. Fortunately, there are several effective ways to manage this both in the short term for your exams and for long-term relief
Next Steps
Topical Antiperspirants: Using a clinical-strength antiperspirant containing Aluminum Chloride (20%) at bedtime is the first line of treatment. It helps block the sweat ducts temporarily.
Iontophoresis: This is a highly effective, non-invasive therapy where a medical device passes a mild electrical current through water to your hands/feet. It significantly reduces sweating after a few sessions.
Botox Injections: For a more immediate and long-lasting effect (6–9 months), Botox can be injected into the palms to block the nerves that trigger sweat glands.
Oral Medications: Anticholinergics can be prescribed, but they are usually a second option due to side effects like dry mouth
Health Tips
On the day of your examination, try to stay as calm as possible, as anxiety acts as a major trigger for hyperhidrosis. Using a specialized antiperspirant lotion (like Aldry or similar) starting a week before the exam can give you much better control. If the condition is severe, I highly recommend consulting a dermatologist to discuss Iontophoresis, as it is often considered the 'gold standard' for palm and feet sweating without involving surgery or needles."
