What should you know about extreme underarm sweating?

Sweating limited mainly to the underarms can begin without heat, exercise or obvious stress. It may affect both sides and can soak shirts, cause skin irritation, or make work and social situations uncomfortable. Some people have a family pattern; others develop increased sweating after a medicine, hormonal change, illness, or another condition. Excessive sweating is a useful overview of the symptom and its possible patterns.

A clinician may ask when the sweating started, whether it happens during sleep, which areas are affected, and whether you have palpitations, fever, weight change or new medicines. The answers help distinguish localised hyperhidrosis from sweating that needs a broader medical review.

Apply a clinician-recommended antiperspirant to completely dry skin, often in the evening, and wash it off as directed. Avoid applying it immediately after shaving if it stings. Breathable clothing, absorbent underarm pads and changing damp garments can reduce friction and irritation.

If daily measures are not enough, treatment may include prescription antiperspirant, injections that temporarily reduce nerve signals to sweat glands, or microwave treatment that targets sweat glands. Discuss expected duration, skin sensitivity and whether the option fits your health history before treatment.

Arrange a medical assessment if sweating is new, rapidly worsening, occurs across the body, happens during sleep, or disrupts work, sleep or confidence. Seek urgent care for heavy sweating with chest pain, fainting, severe breathlessness, confusion or a racing heartbeat.

Ask what pattern of sweating you have, whether a medicine or medical condition could be contributing, how to use an antiperspirant safely, and which treatment is suitable for your underarms. Mention rashes, pain, night sweating and every medicine or supplement you take.
