Why is my face sweating so much?

Some people sweat heavily from the face even when the surroundings are cool or activity is light. This may be focal hyperhidrosis, where sweat glands respond too strongly without an obvious trigger. Sweating with heat exposure can occur during heat exhaustion. Tremor, racing heartbeat, weight change, or heat intolerance may accompany Hyperthyroidism. Sweating with shakiness, weakness, or confusion can occur with Hypoglycaemia. Night sweating, loud snoring, and breathing pauses can point toward Obstructive Sleep Apnoea. Timing, triggers, medicines, and other symptoms help guide evaluation.

Keep a record of when facial sweating occurs, what you were doing, and whether it affects sleep or daily tasks. Stay hydrated in hot conditions, use breathable clothing, and review medicines with a clinician rather than stopping them yourself. A dermatologist may discuss options such as Botox For Sweating, Iontophoresis, or Microwave Sweat Gland Treatment when appropriate. Treatment depends on the area involved and the underlying cause.

Arrange an assessment when sweating is new, severe, occurs at night, or begins after a medicine change. Seek urgent care for heavy sweating with chest pain, fainting, severe breathlessness, confusion, very high body temperature, or signs of heat exhaustion. Shaking and confusion with sweating can also require immediate help.

Could this be focal hyperhidrosis or a secondary cause? Should my thyroid, glucose, sleep, or medicines be reviewed? Which treatment is suitable for facial skin and what side effects should I expect?
