Search for help with excessive sweating and you will be sold an outcome before anyone has understood your cause. The adverts promise dryness, confidence, a fresh start — as though hyperhidrosis were a styling problem rather than a recognised medical condition. That framing is not just distasteful; it is clinically backwards. It skips the only step that matters: working out what is actually driving the sweat, and whether a treatment is appropriate for you at all.
Here is the honest version. Hyperhidrosis is sweating that goes beyond what your body needs to control its temperature. For some people it is primary — the nervous system signalling the sweat glands to overwork for no underlying reason — and it usually shows up symmetrically, in the underarms, palms, soles, or face. For others it is secondary to something else: a thyroid issue, a medication, an anxiety state, a hormonal shift, sometimes an infection. The two are managed completely differently, and the difference is the whole point of seeing a clinician rather than buying a treatment off a price list.
This page explains how excessive sweating is properly assessed, what genuinely helps, what it costs, and why the person holding the needle should understand the anatomy underneath it.

First question
Stepwise approach
Four signals to choose a clinic
All treatments assessed and prescribed by Dr Vishal Patel, BDS, MSc Aesthetic & Restorative Dentistry (Manchester), GDC 103127.
| Assessment — Primary vs Secondary (Consultation £65, redeemable against treatment) | Before treatment, we assess whether hyperhidrosis is primary or secondary. This step is crucial to avoid treating the wrong condition. Primary focal hyperhidrosis starts in adolescence, affects symmetrical areas, and eases during sleep. Secondary hyperhidrosis comes on later, affects the whole body, and may indicate an underlying health issue. We will not treat until secondary causes are ruled out. |
| Step 1 — Clinical-strength Antiperspirants (Low cost) | First-line intervention: aluminium-chloride antiperspirant applied to dry skin at night. Suitable for mild to moderate underarm sweating. It is not glamorous but is often sufficient. We always recommend this before proceeding to injections. |
| Step 2 — Prescription Injectable Treatment (Effect ~6-9 months) | Botulinum toxin type A injections block nerve signals to sweat glands. Effect develops over 7-14 days, lasts several months. Administered after clinical assessment. The treatment is prescribed by Dr Vishal Patel. Underarm treatment is most effective; palmar and plantar treatment is available but more uncomfortable. |
| Step 3 — Further Options and Specialist Referral | For severe or treatment-resistant cases, particularly hand hyperhidrosis, we refer to specialists. We know the edge of our remit and do not overreach. An honest clinic refers when needed. |

Questions
people ask
If your question isn't answered here, call reception on 020 8127 4567 or email reception.
Will it stop sweating completely?
Substantial reduction (typically 80%+ in treated area for underarm cases) but not complete elimination. Some baseline sweating is preserved which is appropriate — complete elimination isn't desirable for thermoregulation.
What if my sweating is caused by something else?
If your assessment suggests a secondary cause — a thyroid issue, a medication, a hormonal shift — the right step is investigation with your GP, not an injectable. We will say so directly.
How long does injectable treatment for sweating last?
For underarm hyperhidrosis the effect typically lasts several months before gradually fading, at which point the treatment can be repeated. The exact duration varies between individuals.
Will it make me sweat more elsewhere?
Compensatory sweating (increased sweating in untreated areas) occurs in a minority of patients. Usually mild. Discussed at consultation. For patients where compensatory sweating would be problematic we'd assess case-by-case.
Will treating my underarms make me sweat more elsewhere?
A small number of people notice slightly increased sweating in untreated areas (compensatory sweating). It is usually minor, and it is part of the honest conversation we have before you decide.
Can you treat sweaty hands and feet as well as underarms?
Underarm treatment is the most straightforward. Hands and feet can be treated but are more uncomfortable and sometimes better suited to specialist referral; we give an honest view at assessment.
Does hyperhidrosis treatment hurt?
The injections are very fine and most people tolerate underarm treatment comfortably; sensitive areas such as the palms can be more uncomfortable, and we discuss comfort measures beforehand.
Is hyperhidrosis a medical condition or a cosmetic one?
It is a recognised medical condition. Excessive sweating beyond the body's thermoregulatory need can significantly affect work, clothing, and social life, and it is assessed and managed clinically.
