When is microwave sweat gland treatment recommended for bromhidrosis?

Bromhidrosis is noticeable body odour produced when skin secretions are broken down by microorganisms. Sweat glands in the underarm can contribute moisture and secretions that support this process. Microwave energy is directed at sweat-gland tissue, with the aim of reducing gland activity in the treated area. It does not replace assessment for infection, skin inflammation, medication effects or another cause of a new odour.

A clinician may consider the pattern of odour, sweating, skin changes and previous treatment before suggesting this option. The treatment area, expected response, possible tenderness, swelling or altered sensation, and aftercare should be discussed individually.

Arrange a dermatology assessment if odour continues after regular cleansing, thorough drying, breathable clothing and an appropriate antiperspirant or topical product. Bring a list of products used and explain whether sweating, rash or irritation accompanies the odour. Your clinician may first address a treatable skin condition or adjust topical care. If microwave treatment is suitable, ask how the area will be marked, how discomfort will be managed and when normal activities can resume.

Seek prompt medical advice for sudden or strongly changed body odour, painful lumps, spreading redness, warmth, drainage, fever or a rapidly developing rash. These features can point to infection or another condition needing examination rather than an elective sweat-gland procedure. Contact the treating clinic if marked swelling, worsening pain, blistering or unexpected skin colour change develops after treatment.

Ask whether the odour is confirmed as bromhidrosis, what other causes should be excluded, which treatments you have already tried, and whether microwave treatment fits your skin and medical history. Also ask about expected improvement, side effects, aftercare and alternatives if the response is limited.
