Does sweaty palms cause excessive sweating?

Sweaty palms, also called palmar hyperhidrosis, means the palms produce more sweat than needed for cooling. Most people with Sweaty Palms notice excessive sweating, often on both hands and during conversations, work, stress, heat, or exercise. The moisture may make writing, using touchscreens, shaking hands, or holding objects difficult.

Hand sweating can begin early in life and may occur without an underlying illness, but a new or widespread change deserves assessment. Medicines, thyroid problems, infections, low blood sugar, and other conditions can also increase sweating. The distribution, timing, sleep symptoms, and accompanying signs help a clinician distinguish patterns.

Record when sweating occurs, whether both palms are involved, and whether the hands are dry during sleep. Mention new medicines, caffeine, heat exposure, anxiety symptoms, weight change, tremor, or night sweats at an appointment. A clinician may recommend a topical antiperspirant, other prescription treatment, or a procedure depending on severity and response.

Keep the hands dry with absorbent materials and protect irritated skin with a gentle moisturiser. Avoid applying strong products to cracked skin unless a clinician advises it, because irritation can worsen discomfort.

Arrange medical review for sweating that begins suddenly, occurs throughout the body, soaks clothing at night, or comes with fever, unexplained weight change, tremor, dizziness, chest symptoms, or a racing heartbeat. Seek emergency help for chest pain, severe breathlessness, fainting, confusion, or signs of serious illness.

Ask whether your pattern fits palmar hyperhidrosis, whether a medicine or medical condition could be contributing, and which treatment is appropriate for your skin. Discuss how to protect against irritation, when improvement should be reviewed, and what symptoms should prompt urgent help.
