Surgery for Underarm Sweating

You can move through a long day without worrying about damp patches under your arms or a body odour that makes you hesitant to stand close to anyone.

Is this right for you?

Excessive underarm sweating (known medically as focal axillary hyperhidrosis, where you produce more sweat than your body needs to cool itself) is a real concern that can affect your work, your social life and your clothes. Surgery is usually considered when gentler approaches have not done enough for you.

This may be a good fit if

  • You have heavy, long-standing underarm sweating that soaks your shirts or causes odour, even when you keep the area clean.
  • You have already tried less invasive options (strong aluminium-based antiperspirants, medication, or botulinum injections) and the results were not enough or did not last.
  • Your general health is stable and you can set aside time to let the incision heal.
  • You want a clear reduction in sweating, and you understand the goal is to reduce it rather than to make the area completely dry.

This may not be right if

  • Your sweating affects your whole body or came on suddenly, since this can point to an underlying condition that should be investigated first.
  • You currently have an infection, a skin inflammation, or an open wound in the underarm area.
  • You are pregnant, breastfeeding, or have a bleeding disorder that is not yet under control.
  • You expect your underarm to stop sweating entirely, which is not something this surgery can deliver.

How it works

It all starts with an examination and a conversation. Your doctor will ask how much you sweat, what you have already tried, your medical history and the medicines you take. They may do a simple test to map where you sweat the most, while also ruling out whole-body causes. This is also the moment to share what you are hoping for and to ask any question you have.

Underarm surgery is usually done under local anaesthetic, sometimes with sedation to help you feel more comfortable; the exact form of anaesthesia depends on the technique and on your health. The broad aim of the surgery is to remove or reduce the activity of the sweat and odour glands that sit just beneath the skin of the underarm.

Depending on your case, your doctor may choose to suction away the gland layer under the skin through a small incision, or to directly remove the patch of skin that carries the most glands; the technique preferred at the clinic will be discussed with you in detail. Once the work is done, your doctor closes the incision and usually applies a pressure dressing to limit fluid build-up.

The procedure usually takes somewhere between one and two hours, depending on the technique and how much area is treated. Most cases can go home the same day, though the final decision rests with your doctor and your condition.

Realistic expectations

The realistic goal of surgery is to meaningfully reduce the amount of sweat and odour in your underarm, so that daily life feels more comfortable. This is an improvement in degree, not a complete removal.

What this will not do

  • Surgery does not stop your underarm from sweating altogether, because your body still needs to sweat to regulate its temperature.
  • Surgery does not address sweating in other areas such as the palms, the soles of the feet, or the whole body.
  • Surgery does not treat a whole-body cause if your sweating comes from an underlying condition.
  • Your doctor will not commit to a fixed number for how much sweat will be reduced, because results vary from person to person.

Recovery

Recovery after underarm surgery is usually gentle, but you will need to limit strong arm movements in the first few days so the incision can settle. The milestones below are rough estimates; your doctor will adjust them to your technique and your body.

The first few days
You may feel mild pain, tightness, bruising or swelling around the underarm. You are usually kept in a pressure dressing and asked to avoid raising your arms high.
Around 1 to 2 weeks
The incision gradually dries and settles. Your doctor will often arrange a follow-up visit to check it and remove stitches if needed. Many people return to office work during this period, depending on what their work involves.
Around 3 to 6 weeks
You gradually return to vigorous activity and to exercising the shoulder and arm, following your doctor's guidance. A feeling of tightness or mild numbness can still linger.
A few months
The scar continues to fade and the tissue becomes softer. How much your sweating has eased can be judged more clearly once the underarm has fully healed.

Risks & safety

Every surgery carries risk, and you deserve to understand it clearly before you decide. Your doctor will talk through the risks that apply specifically to your case.

  • Bleeding, a blood collection (haematoma) or a fluid collection under the skin of the underarm, sometimes needing further treatment.
  • Infection of the incision, which may call for antibiotics or longer care.
  • Scarring, including raised or contracted scars, especially in people prone to poor scarring.
  • Numbness, reduced sensation or unusual feelings in the underarm and the inner arm, which may be temporary or lasting.
  • Slow wound healing or breakdown at the skin edge, particularly with some of the skin-removal techniques.
  • Sweat reduction that falls short of what you hoped for, or that returns over time, which may need additional treatment.
  • A temporary limit in how far you can move your arm during the early part of recovery.

How we do it

At The Gioi Dep, our doctors begin by understanding why you are sweating and ruling out whole-body causes, rather than assuming surgery is the first step. When surgery is the right choice, your doctor will explain each possible technique, why one approach is chosen over another, and what you can honestly expect.

We carry out the procedure in a sterile setting, monitor you during and after it, and give you clear guidance on caring for the incision at home along with your follow-up schedule. If you need further attention or have questions during recovery, our team is here to stay alongside you.

Frequently asked questions

Will the surgery hurt a lot?

During the procedure, the underarm is numbed, so you do not feel pain. Afterwards you may have mild pain and tightness for a few days, which is usually managed with pain relief prescribed by your doctor.

How long do I need off work?

Many people return to light work after about one to two weeks. Jobs that need a lot of arm strength or vigorous movement usually call for more time off; your doctor will advise based on your situation.

Will the scar be obvious?

The incision is usually placed in the natural crease of the underarm so it shows less. The scar fades over time, but how much depends on your skin, and some people scar more readily than others.

Will I still sweat after the surgery?

The underarm usually sweats noticeably less, but it does not become completely dry. Your body still needs to sweat to regulate its temperature, so the goal is to reduce it to a level that feels comfortable for you.

Can the sweating come back later?

For some people, the effect can ease over time. If that happens, you can talk with your doctor about additional treatment options.

Am I too old for this?

Age on its own is not the deciding factor. What matters more is your general health and the underarm being free of infection or skin problems, all of which is assessed at your examination.

Do I need to try other approaches before surgery?

Usually yes. Doctors often consider less invasive options first, such as specialised antiperspirants, medication or botulinum injections, and view surgery as the choice when those have not done enough for you.

Will the surgery affect how I move my arm?

In the early stage, you should avoid raising your arms high and doing vigorous movement so the incision can settle. Your range of motion usually returns to normal after a few weeks, following your doctor's guidance.

When will I see clear results?

You may notice a change early on, but the clearest judgement comes once the underarm has fully healed, usually after a few weeks to a few months.
