Microwave Sweat Gland Treatment for Underarm Sweating

Microwave sweat gland treatment delivers controlled energy to the underarm area to reduce the activity of sweat glands. The treatment is designed for the axillae, the medical term for underarms, rather than general body sweating. It may be considered for people whose underarm sweating or odour remains troublesome despite practical measures and first-line care. A clinician should first confirm the pattern and exclude an underlying cause when indicated.

Local anaesthetic is commonly used so the area is numb during the energy delivery. You may notice pressure, pulling, or warmth rather than sharp pain. Tenderness and swelling can occur after the appointment, and the clinic can advise on cooling measures and appropriate pain relief based on your health history.

Safety depends on correct patient selection, a trained provider, and appropriate use of the device. The consultation should cover skin conditions in the underarms, implants or medical devices, medicines, allergies, pregnancy, previous procedures, and any nerve symptoms. The provider should explain expected local effects and the uncommon complications that would need follow-up.

The aim is to reduce activity in treated underarm sweat glands. Response and the number of treatment sessions are individual, so a clinician will assess whether more than one session is suitable. This procedure does not treat sweating on the hands, feet, face, or other areas, and it does not replace evaluation of sudden or whole-body sweating.

This treatment targets underarm sweating and may also help when odour is linked to sweat and underarm bacteria. It is different from treatments that temporarily reduce nerve signalling to sweat glands. Wear loose clothing for the visit and follow any instructions about shaving, deodorant, and antiperspirant so the skin can be assessed and treated safely.

People with persistent underarm sweating that soaks clothing, disrupts work, or causes distress may wish to discuss this option. Underarm sweating can be a presentation of axillary hyperhidrosis; hyperhidrosis may also affect other body areas and need a wider plan. The consultation considers symptom distribution, onset, triggers, skin health, and treatments already tried.

The clinician marks the underarm treatment area, cleanses the skin, and applies local anaesthetic. The handpiece is placed against the skin in a planned pattern while controlled microwave energy is delivered. Both underarms are treated during the visit when appropriate. Before you leave, the team checks comfort and provides written guidance for swelling, activity, and warning signs.

Swelling, tenderness, bruising, numbness, and a feeling of firmness in the underarm tissue may appear afterwards. These effects usually ease as the area settles, but recovery differs between people. Avoid friction and strenuous upper-body activity until your provider says it is comfortable. Seek prompt advice for worsening pain, blistering, skin colour change, drainage, fever, or weakness in the arm or hand.

Local reactions can include swelling, bruising, altered sensation, tenderness, and temporary lumps or firmness. Less commonly, skin injury, infection, prolonged numbness, or nerve-related symptoms can occur. Contact the treating clinic if symptoms are escalating rather than settling. An experienced provider can explain how your anatomy and health history affect the plan.

Strong antiperspirants, lifestyle adjustments, and prescription treatments may be appropriate first. Botulinum toxin for sweating can reduce sweat-gland signalling for a period and may suit someone seeking a non-energy approach. If sweating is widespread or began suddenly, assessment for a medical cause is more important than focusing solely on the underarms.

Choose a clinician who regularly assesses hyperhidrosis and can distinguish underarm symptoms from generalised sweating. Ask how they evaluate suitability, manage numbness or swelling, and arrange follow-up. Bring a record of the areas involved, triggers, medicines, and previous treatments so the consultation can focus on the pattern that affects you.
