When should you worry about excessive sweating if you have sweaty palms?

Palmar hyperhidrosis involves sweating from the hands beyond what is needed for cooling. It may make writing, using a phone, handling tools, shaking hands, or gripping objects difficult. Both hands are often involved, and episodes may be triggered by heat, emotion, or activity. A new or whole-body pattern can point to medicine effects or another health issue and merits review.

Keep hands clean and dry, use absorbent materials when handling objects, and protect cracked skin with a fragrance-free moisturiser. Note triggers, timing, affected areas, and how the sweating changes your activities. A clinician can discuss treatments suited to your pattern and check for contributing conditions.

Seek urgent help for sweating with chest pain, fainting, severe breathlessness, marked weakness, or confusion. Arrange a prompt appointment if the problem starts abruptly, occurs during sleep, follows a medicine change, causes skin infection, or significantly limits work or social contact.

Ask whether the pattern is consistent with palmar hyperhidrosis, which treatments fit your skin, and whether tests or a medicine review are appropriate.
