Excessive sweating

Excessive sweating

Definition

Excessive sweating is when you sweat more than you might expect based on the surrounding temperature or your activity level or stress. Excessive sweating can disrupt daily activities and cause social anxiety or embarrassment.

Excessive sweating, or hyperhidrosis (hi-pur-hi-DROE-sis), can affect your entire body or just certain areas, such as your palms, sole

Hyperhidrosis (hi-pur-hi-DROE-sis) is excessive sweating that's not always related to heat or exercise. You may sweat so much that it soaks through your clothes or drips off your hands. Heavy sweating can disrupt your day and cause social anxiety and embarrassment.

Hyperhidrosis treatment usually helps. It often begins with antiperspirants. If these don't help, you may need to try different medications and therapies. In severe cases, your health care provider may suggest surgery to remove the sweat glands or to disconnect the nerves related to producing too much sweat.

Sometimes an underlying condition may be found and treated.

Symptoms

The main symptom of hyperhidrosis is heavy sweating. This goes beyond the sweating from being in a hot environment, exercising, or feeling anxious or stressed. The type of hyperhidrosis that usually affects the hands, feet, underarms or face causes at least one episode a week when you're awake. And the sweating usually happens on both sides of the body.s, underarms or face. The type that typically affects the hands and feet causes at least one episode a week, during waking hours.

Causes

Sweating is the body's mechanism to cool itself. The nervous system automatically triggers sweat glands when your body temperature rises. Sweating also occurs, especially on your palms, when you're nervous.

Primary hyperhidrosis is caused by faulty nerve signals that trigger eccrine sweat glands to become overactive. It usually affects the palms, soles, underarms and sometimes the face.

There is no medical cause for this type of hyperhidrosis. It can run in families.

Secondary hyperhidrosis is caused by an underlying medical condition or by taking certain medications, such as pain relievers, antidepressants, and some diabetes and hormonal medications. This type of hyperhidrosis may cause sweating all over the body. Conditions that might cause it include:

Diabetes

Menopause hot flashes

Thyroid problems

Some types of cancer

Nervous system disorders

Infections

Risk factors

Risk factors for hyperhidrosis include:

Having a blood relative, such as a parent, sibling or grandparent, who sweats heavily

Taking medicines or supplements that cause sweating

Having a medical condition that causes sweating

Complications

Complications of hyperhidrosis include:

Infections. People who sweat a lot are more prone to skin infections.

Social and emotional effects. Having clammy or dripping hands and sweat-soaked clothes can be embarrassing. Your condition may affect your pursuit of work and educational goals.

Diagnosis

Diagnosing hyperhidrosis may start with your health care provider asking about your medical history and symptoms. You may also need a physical exam or tests to further evaluate the cause of your symptoms.

Lab tests

Your health care provider may recommend blood, urine or other lab tests to see if your sweating is caused by another medical condition, such as an overactive thyroid (hyperthyroidism) or low blood sugar (hypoglycemia).

Sweat tests

Or you may need a test that pinpoints the areas of sweating and evaluates how severe your condition is. Two such tests are an iodine-starch test and a sweat test.

Treatment

Treating hyperhidrosis may start with treating the condition causing it. If a cause isn't found, treatment focuses on controlling heavy sweating. If new self-care habits don't improve your symptoms, your health care provider may suggest one or more of the following treatments. Even if your sweating improves after treatment, it may recur.

Medications

Drugs used to treat hyperhidrosis include:

Prescription antiperspirant. Your health care provider may prescribe an antiperspirant with aluminum chloride (Drysol, Xerac AC). Apply it to dry skin before going to bed. Then wash the product off when you get up, taking care to not get any in your eyes. Once you start seeing results from using it daily for a few days, you can scale back to once or twice a week to maintain the effect.

This product can cause skin and eye irritation. Talk with your health care provider about ways to reduce side effects.

Prescription creams and wipes. Prescription creams that contain glycopyrrolate may help hyperhidrosis that affects the face and head. Wipes soaked in glycopyrronium tosylate (Qbrexza) may ease symptoms of the hands, feet and underarms. Possible side effects of these products include mild skin irritation and dry mouth.

Nerve-blocking medications. Some pills (oral medications) block the nerves that trigger sweat glands. This can reduce sweating in some people. Possible side effects include dry mouth, blurred vision and bladder problems.

Antidepressants. Some medications used for depression can also decrease sweating. They may also help decrease anxiety.

Botulinum toxin injections. Treatment with botulinum toxin (Botox) blocks the nerves that trigger the sweat glands. Most people don't feel much pain during the procedure. But you may want your skin numbed beforehand. Your health care provider might offer one or more of the methods used to numb skin. These include topical anesthesia, ice and massage (vibration anesthesia).

Each affected area of your body will need several injections. It may take a few days to notice results. To retain the effect, you'll likely need repeat treatments about every six months. A possible side effect is short-term muscle weakness in the treated area.

Surgical and other procedures

Your health care provider might suggest other treatments:

Iontophoresis. With this home treatment, you soak your hands or feet in a pan of water while a device passes mild electric current through the water. The current blocks the nerves that trigger sweating. You can buy the device if you have a prescription from your health care provider.

You'll need to soak the affected areas for 20 to 40 minutes. Repeat the treatment 2 to 3 times a week until your symptoms improve. After you get results, you can reduce treatments to once a week or once a month to maintain the effect. Talk with your health care provider if you experience side effects.

Microwave therapy. With this therapy, a handheld device (miraDry) delivers microwave energy to destroy sweat glands in the armpits. Treatments involve two 20- to 30-minute sessions, three months apart. Possible side effects are a change in skin sensation and some discomfort. Long-term side effects are unknown.

Sweat gland removal. If you sweat heavily only in your armpits, your health care provider may suggest removing those sweat glands. This may be done through scraping them away (curettage), suctioning them out (liposuction) or using a combination of the two (suction curettage).

Nerve surgery (sympathectomy). During this procedure, the surgeon removes a small section of the spinal nerves that control sweating in your hands. A possible side effect is permanent heavy sweating in other areas of your body (compensatory sweating). Surgery is generally not an option for isolated head and neck sweating. A variation on this procedure treats the palms. It interrupts the nerve signals without removing the sympathetic nerve (sympathotomy), which reduces the risk of compensatory sweating.

Because nerve surgery has a risk of side effects and complications, it is usually only considered for people who have tried many other treatments without good results.

Each of these procedures may be done with general anesthesia or with local anesthesia and sedation.
