Symptoms

Most people sweat when they exercise or exert themselves, are in a hot environment, or are anxious or under stress. The excessive sweating experienced with hyperhidrosis far exceeds such normal sweating.

The type of hyperhidrosis that usually affects the hands, feet, underarms or face causes at least one episode a week, during waking hours. And the sweating usually occurs on both sides of the body.

When to see a doctor

Sometimes excessive sweating is a sign of a serious condition.

Seek immediate medical attention if your heavy sweating is accompanied by lightheadedness, chest pain or nausea.

See your doctor if:

• Sweating disrupts your daily routine
• Sweating causes emotional distress or social withdrawal
• You suddenly begin to sweat more than usual
• You experience night sweats for no apparent reason
