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

Bromhidrosis is unpleasant body odour that can arise when sweat interacts with skin bacteria. Microwave energy targets underarm sweat glands, so odour may improve when moisture is reduced, but it is not the only factor. Bacteria, hair, clothing, skin folds, deodorant products, and an underlying skin condition can all influence smell. Temporary swelling, tenderness, numbness, or irritation can also make the underarm feel different while it heals.

Persistent odour after treatment does not by itself show that the procedure failed. The clinician may need to check sweating, skin inflammation, infection, and product triggers before interpreting the result.

Follow the clinic’s washing and cooling instructions, and avoid scrubbing, picking, shaving, or applying irritating products until the skin barrier has recovered. Wear clean, breathable clothing and change damp garments promptly. Do not add strong antibacterial or fragranced products without advice, because irritation can worsen odour and delay healing. Record changes in moisture, smell, tenderness, and rash for the follow-up visit.

Contact the treating clinic if odour is accompanied by increasing pain, spreading redness, pus, marked swelling, blistering, or a new rash. Fever or rapidly worsening tenderness needs prompt assessment. If the smell persists despite less sweating, or appears in another body area, ask for a skin examination because bromhidrosis can have causes that this procedure does not address.

Ask whether your odour is mainly related to underarm sweating, whether infection or dermatitis should be ruled out, and when improvement should be reviewed. Discuss aftercare products, hair removal, clothing, medicines, and what options remain if odour continues.
