When is microwave sweat gland treatment recommended for hyperhidrosis?

Hyperhidrosis means sweating is greater than the body needs for cooling. Microwave treatment targets sweat-gland tissue in the underarm, where energy is delivered through the skin to reduce local gland activity. It is a local treatment, so it is not intended to control sweating from every body region.

A dermatology clinician may review when sweating occurs, whether it affects sleep, work or clothing, which areas are involved, and whether medicines or another health problem could be contributing. Treatment may be discussed after topical care or other appropriate options have been considered. Possible tenderness, swelling, altered sensation and temporary activity restrictions should be covered during consultation.

Keep a brief record of the areas that sweat, triggers, impact on routine and products or treatments already tried. Tell the clinician about skin sensitivity, implanted devices, medicines and any history of unusual sweating. Ask whether the underarm is the right target and what improvement is realistic for you. You can review [Microwave Sweat Gland Treatment](/treatments/laser-and-energy/microwave-sweat-gland-treatment/) before your appointment.

Arrange medical assessment for sweating that starts suddenly, occurs mainly during sleep, affects the whole body or comes with weight change, fever, chest discomfort, faintness or shortness of breath. These features can require evaluation for an underlying cause. After treatment, contact the clinic for increasing pain, spreading redness, drainage, blistering or significant changes in sensation.

Ask what type of hyperhidrosis you may have, whether a medicine or condition could be contributing, why microwave treatment is being considered, and which alternatives remain available. Clarify the treated area, preparation, discomfort control, aftercare, expected timeline and signs that need review.
