Hyperhidrosis
Axillary hyperhidrosis is a medical condition characterised by excessive sweating in the underarm (axillary) area that occurs independently of heat, exercise, or emotional stress. The sweating is often persistent, unpredictable, and disproportionate to the body’s normal need for temperature regulation. For many people, axillary hyperhidrosis can significantly interfere with daily life, leading to visible sweat marks on clothing, frequent need for clothing changes, and concern about body odour. These challenges can result in embarrassment, reduced confidence, and avoidance of social, professional, or physical activities. Although axillary hyperhidrosis is not dangerous, its impact on quality of life can be substantial. Fortunately, a range of effective medical treatments are available, and assessment by a dermatologist can help determine the most appropriate management approach based on symptom severity and individual needs.
The Science Behind It
Hyperhidrosis occurs when the body’s sweat-regulating system becomes overactive, causing the sweat glands to produce more sweat than is needed for temperature control. Sweating is regulated by the autonomic (sympathetic) nervous system, which sends signals to the sweat glands in response to heat, physical activity, or emotional stimuli.
In people with hyperhidrosis, these nerve signals are exaggerated, leading to excessive sweating even in cool conditions or at rest. Triggers such as heat, stress, or anxiety may worsen symptoms, but the sweating itself is not dangerous. Identifying the underlying type of hyperhidrosis helps guide appropriate treatment, which can significantly improve symptoms and quality of life.
