Hyperhidrosis is a condition that causes abnormally excessive sweating that hasn’t necessarily been triggered by physical activity or a rise in temperature.
The most common form of hyperhidrosis is called primary focal hyperhidrosis, and affects the water-producing ‘eccrine’ sweat glands. With this type, the nerves responsible for signalling your sweat glands become overactive, thus resulting in heavy sweating, commonly affecting the armpits, hands, feet and scalp.

Besides disrupting normal daily activities, controlling symptoms can be a constant challenge. This type of heavy sweating can cause social anxiety and embarrassment, and cause people to avoid certain work or social situations, as well as avoiding wearing certain coloured clothing or fabrics.

Secondary hyperhidrosis is excessive sweating that happens due to another medical condition such as diabetes, menopause, thyroid disorders, and certain medications.
