Is My Sweating Normal? When It's Hyperhidrosis - and What Can Be Done

Everyone sweats through a workout, a heat wave, or a job interview. But if you're soaking through shirts at your desk, avoiding handshakes, keeping a spare outfit at work, or planning your wardrobe around sweat marks - that's not a personality quirk or a hygiene failure. It has a name, and it's treatable.

What Counts as Hyperhidrosis

Hyperhidrosis means sweating well beyond what your body needs for temperature control. The classic pattern - primary focal hyperhidrosis - affects specific zones: underarms, palms, soles, forehead, or scalp, usually on both sides, often starting in the teens or twenties, and typically sparing sleep. It affects roughly 2–3% of people, most of whom never mention it to a doctor because they assume nothing can be done.

Quick Self-Check

• Does sweating interfere with work, social situations, or what you choose to wear?
• Do you sweat noticeably even when cool and calm?
• Do specific areas soak while the rest of you is dry?
• Has it been going on for six months or more?

Two or more yeses is worth a conversation.

When Sweating Deserves a Medical Look First

Sweating that is new in adulthood, all-over rather than focal, night-dominant, or accompanied by weight loss, fever, or palpitations should be assessed to rule out an underlying cause before treating the sweating itself. This is part of why seeing a physician - rather than heading straight to a med spa - matters.

Treatment, From Simple to Definitive

• Clinical-strength antiperspirants (aluminum chloride, applied at night to dry skin) - the right first step, and better than most people expect. See the low-allergenic options handout if your skin is sensitive
• Prescription options - topical and oral medications that dial down sweat gland activation
• Botox injections - Health Canada approved, quick, and remarkably effective: a localized treatment that switches off overactive sweat glands for months at a time, often covered by private insurance

For patients with dysautonomia - common alongside hypermobility and EDS - temperature regulation can be erratic, and treatment is planned with that context in mind.

If sweating is running your wardrobe or your confidence, it's a medical problem with medical solutions. Start here.
