Frequently Asked Questions
Q. Does a sudden onset of excessive sweating always mean hyperhidrosis?
A. No, sudden perspiration due to a readily apparent cause is called diaphoresis. Caffeine or nicotine can cause diaphoresis, as can a plate of spicy food. People recovering from fever frequently experience diaphoresis.
Hyperhidrosis Treatment
Antiperspirant
The first line of treatment is topical application of strong antiperspirant to the affected area. Aluminum chloride is the most common active ingredient in both prescription and non-prescription antiperspirants labeled “clinical strength.” For axillary hyperhidrosis, prescription antiperspirant may be sufficient, although the strength of these formulas can cause localized skin irritation.
Hyperhidrosis Diagnosis
Although excess perspiration is readily visible and makes diagnosis of hyperhidrosis itself simple, a physician will want to investigate any underlying causes.
Hyperhidrosis Symptoms
The defining symptom of hyperhidrosis is excessive sweating. While the definition of “excessive” is somewhat subjective, people with hyperhidrosis can readily separate sweating that interferes with daily life from the usual perspiration during exercise or on hot days.
