Excessive Sweating (Hyperhidrosis)

When sweating goes beyond normal and how your GP can help

What excessive sweating means

Sweating is a normal process that helps regulate body temperature. Hyperhidrosis describes sweating that is excessive for the situation, such as soaking clothes or dripping from the hands, feet, underarms, face, or scalp without heat or exertion. This condition is separate from night sweats, which occur during sleep and have different causes.

Primary and secondary hyperhidrosis

Doctors broadly describe two patterns. Primary hyperhidrosis usually begins earlier in life and often affects specific areas like the palms, soles, underarms, or face. It tends to be symmetrical and occurs while you are awake. Secondary hyperhidrosis develops later and relates to another factor, such as medicines, hormonal changes, infections, or underlying medical conditions. Distinguishing between these patterns matters because it guides investigation and management.

Why excessive sweating affects daily life

Persistent sweating can interfere with work, social interactions, confidence, and mental wellbeing. People often adjust clothing choices, avoid handshakes, or limit activities to manage symptoms. These impacts are real and deserve attention. Hyperhidrosis is not a sign of poor hygiene or anxiety alone, and it is not something you simply need to “put up with”.

What can trigger or worsen symptoms

Sweating patterns often fluctuate. Stress, heat, certain foods, caffeine, alcohol, and hormonal changes can increase sweating in some people. Some medicines also contribute. Recognising patterns helps your GP understand whether sweating fits a primary pattern or whether another cause needs review.

When a GP review is important

A GP assessment helps clarify the type of hyperhidrosis you are experiencing and whether any underlying cause needs investigation. Review is especially important if sweating starts suddenly, becomes generalised rather than localised, or is associated with weight loss, fever, palpitations, tremor, or other new symptoms. These features may suggest a secondary cause that needs targeted care.

How your GP supports management

Your GP works with you to understand triggers, daily impact, and treatment preferences. Management focuses on reducing symptoms and improving quality of life, not just on sweating volume alone. Even when hyperhidrosis is primary and long-standing, structured care can make symptoms more manageable and reduce their effect on daily activities.
