What is the leading cause of hyperhidrosis?

The leading cause of hyperhidrosis is indeed genetics. Hyperhidrosis is a condition characterized by excessive sweating that often does not relate to environmental factors or physical activity. Research indicates that it tends to run in families, suggesting a hereditary component. Individuals with a family history of hyperhidrosis are more likely to develop the condition themselves.

While factors like infections, heat exposure, and hormonal changes can influence sweating, they are typically secondary causes or related to specific circumstances rather than the primary cause. Thus, understanding that genetics plays a crucial role helps in addressing the condition effectively, allowing for potential treatments or management strategies that take the hereditary nature into account.
