Why Are My Palms Always Sweaty?

A pattern that is persistent, difficult to control, or disruptive to writing, gripping objects, work, or social contact deserves assessment. The timing, triggers, other body areas involved, and associated symptoms help narrow the explanation.

Primary focal hyperhidrosis often affects both palms and may also involve the soles or underarms. It can begin without heat or exercise and may intensify with stress. Sweating that starts suddenly, occurs during sleep, affects the whole body, or accompanies a new medicine is more suggestive of another trigger.

Hyperthyroidism can present with increased sweating alongside heat intolerance, tremor, a racing heartbeat, or weight change. Hypoglycaemia can include sweating with shakiness, hunger, confusion, or weakness. These symptom combinations guide assessment; sweaty palms by themselves do not establish either diagnosis.

Note when sweating occurs, whether it wakes you, which areas are involved, and any links with meals, caffeine, heat, anxiety, exercise, or medicines. Keep hands dry when practical and follow label directions if using an antiperspirant formulated for the hands; stop if the skin becomes sore or cracked.

If self-care is insufficient, a clinician may discuss iontophoresis, which passes a mild electrical current through water around the hands, or botulinum toxin injections that temporarily reduce nerve signals to sweat glands. Choice depends on skin condition, medical history, treatment burden, expected benefit, and possible adverse effects.

Book an assessment for a new or worsening pattern, drenching night sweats, whole-body sweating, unexplained weight change, persistent palpitations, or symptoms beginning after a medication change. Seek urgent help when heavy sweating occurs with confusion, fainting, chest pain, severe breathlessness, or signs of heat illness such as marked weakness, headache, nausea, and dizziness after heat exposure.

Ask whether your pattern fits primary focal hyperhidrosis, whether your medicines or accompanying symptoms suggest another cause, and whether any examination or testing is appropriate. Discuss how each treatment would affect hand function, how irritation or temporary weakness would be managed, and what would signal that the plan should change.
