How to control excessive sweating

Sweating may affect the underarms, palms, feet, face, or several areas. It can be primary hyperhidrosis, which often follows a longstanding pattern, or secondary sweating linked with heat, medicines, hormones, low blood sugar, thyroid disease, sleep problems, or another illness.

Record where and when you sweat, whether it happens during sleep, and whether it began suddenly. This helps separate a persistent local pattern from a new whole-body symptom.

Wear breathable clothing, change damp socks, use absorbent layers, and keep affected skin dry. An antiperspirant applied to completely dry skin at the advised time may help; deodorant mainly controls odour. Protect irritated skin from rubbing and seek advice before applying strong products to broken skin.

A clinician may discuss iontophoresis, botulinum toxin injections, or microwave sweat-gland treatment. The choice depends on the body area, health history, medicines, and how sweating affects daily life.

Arrange medical review for sudden or unexplained sweating, night sweats, sweating with weight change, tremor, palpitations, thirst, or repeated dizziness. Seek urgent help for confusion, fainting, chest pain, severe weakness, or signs of heat exhaustion such as headache, nausea, and marked light-headedness.

Ask whether your pattern suggests primary or secondary sweating, whether medicines or thyroid or glucose problems should be checked, and which treatment fits the affected areas. Discuss skin irritation, treatment frequency, and what improvement would be meaningful for your routine.
