How long does microwave sweat gland treatment take to work for hyperhidrosis?

Hyperhidrosis means sweating beyond what the body needs for cooling. When it is concentrated in the underarms, microwave energy can heat and target sweat glands in that area. Moisture may reduce before the final response is clear, while tenderness, swelling, numbness, or tingling can temporarily distract from the change. Results vary with the severity and pattern of sweating, treatment settings, and individual healing.

Underarm treatment does not explain or treat sweating that begins suddenly, occurs during sleep, or affects the whole body. Those patterns deserve a medical review for an underlying cause.

Follow written instructions for cooling, washing, and pain relief. Avoid friction, shaving, deodorant, heavy exercise, and high heat until the treated area is comfortable and the clinic permits them. Keep a simple record of dampness during usual activities rather than judging the result during a hot day alone. Attend the planned review before considering another treatment or changing prescribed medicines.

Call the clinic if discomfort, redness, swelling, altered sensation, or skin colour change is worsening or not following the expected recovery pattern. Prompt assessment is appropriate for fever, pus, spreading warmth, severe pain, blistering, or arm weakness. Seek medical review for new widespread sweating, night sweats, faintness, palpitations, or unexplained weight change.

Ask which area will be treated, how improvement will be assessed, and when you should return for review. Tell the clinician when sweating began, where it occurs, whether it happens during sleep, and which treatments or medicines you have already tried.
