What should you know about hands that are sweating too much?

Primary hyperhidrosis often affects both palms and may occur while you are otherwise well, including during tasks that need a dry grip. Sweating that begins suddenly, occurs during sleep, or affects the whole body can have another trigger. Heat exhaustion may come with heavy sweating, weakness, dizziness, headache, nausea, or cool clammy skin. Tremor, racing heartbeat, weight change, thirst, or episodes linked to missed meals also deserve review.

Keep a short record of timing, triggers, body areas, sleep symptoms, medicines, and associated sensations. Use breathable materials, dry hands carefully, and ask a clinician before using a strong antiperspirant on irritated skin. Treatment options can include iontophoresis, injections such as Botox for sweating, or other specialist approaches; choice depends on the cause, severity, and areas affected.

Move to a cool place and seek urgent care for heavy sweating with confusion, fainting, severe weakness, chest discomfort, trouble breathing, or inability to drink. Arrange a medical review for new or worsening sweating, night sweats, palpitations, unexplained weight change, or symptoms that occur with fasting or illness.

Ask whether the pattern fits hyperhidrosis, whether medicines or thyroid or glucose problems need checking, and which treatment is suitable for your palms and daily activities.
