Palmar Hyperhidrosis: Causes and Treatment

Palmar Hyperhidrosis

Palmar hyperhidrosis is a pathological condition caused by a malfunction of the eccrine sweat glands located in the skin of the palmar surfaces of the hands and accompanied by increased secretion of sweat.


The functioning of sweat glands depends on the influence of various external and internal factors. Determining the etiology of increased sweating of the hands allows you to choose the most optimal treatment and avoid relapse. When the causes of hand excessive sweating are determined incorrectly, symptomatic therapy can be carried out for life without a marked improvement in the condition.

The main triggers of the disease are:

  • hereditary predisposition, which can cause both a secondary (due to a predisposition to a local form of the disease under the influence of predisposing factors) and a primary disorder caused by an excess of eccrine glands in certain areas of the body, increased sensitivity of sweat glands to nerve stimulation;
  • dysfunction of nerve centers due to a change in the activity of thermoregulatory centers, which are responsible for skin temperature and the rate of sweat secretion;
  • hormonal imbalance also quite often causes increased sweating and is found in adolescents and women during menopause;
  • dermatological disorders such as vitiligo, psoriasis, blue nevus can also cause changes in the intensity of perspiration.

Symptoms of palmar hyperhidrosis may intensify under the influence of stress when eating spices, onions, garlic, and other irritating substances. This disturbance can also be caused by high ambient temperatures.


In such patients, most often the hands are cold and wet. The amount of sweat that has come out can vary widely. The skin of the palms is noticeably pink, the lines and furrows are deep and clear. Sweating occurs during wakefulness and completely disappears during sleep. The patient is forced to constantly wipe off excess moisture with a napkin. In such patients, mittens and gloves very quickly become wet. When touched by hand, wet spots remain on paper, textiles, and other surrounding objects. The first thing that patients with this problem note is communication difficulties. Difficulties arise when you need to lend a hand for a handshake, with loved ones who want close physical contact. Slow dancing, intimate interaction and sex become stressful for both partners, regardless of their degree of trust.


With excessive sweating of the palms, a dermatologist prescribes a list of laboratory and instrumental studies to the patient. The purpose of the extended diagnosis is to confirm that the patient has a local increase in sweating, as well as to identify disorders that may cause the development of palmar hyperhidrosis.

To confirm the diagnosis, a gravimetric test can be prescribed to the patient, allowing you to determine the amount of fluid released per unit time.

Treatment of plantar hyperhidrosis

The choice of an effective treatment method depends on the diseases that provoked hyperhidrosis. To reduce sweating of the palms, My Canadian Pharmacy recommended using antiperspirants, botulinum toxin injections, iontophoresis, neurosurgical sympathectomy. Surgical treatment is used only as a last resort with the low efficiency of conservative methods.

There are 2 approaches to cope with excessive foot sweating: non-surgical (antiperspirants, powders, ointments, pastes), Botox injections, iontophoresis) and surgical (curettage, sympathectomy).


Botox refers to injection techniques. Treatment of hyperhidrosis occurs due to the introduction of the drug with a thin needle into the problem area. Thus, nerve impulses to the sweat glands are blocked. Due to this, the transportation of acetylcholine to the nerve endings is stopped. The effect of the procedure lasts from 6 months to 1 year.


Ionophoresis is a cosmetic procedure, which damages the ion channels of the sweat glands under the influence of electric current. It is the best possible way to get rid of excessive sweating of the arms and legs. The patient puts his hands or feet in a special cell with water through which current flows. Typically, treatment includes 10 daily sessions (each lasting about 15 minutes). The effect allows you to get rid of high sweating for several months.


  • convenience;
  • painlessness;
  • security.


It provides for the elimination of the incorrect effect of autonomic nerve endings on the sweat glands, as a result of which they cease to produce sweat. It is mainly used for the axillary zone.


It can be carried out with sweating hands. Moreover, under general anesthesia, the corresponding nerves are removed through small incisions. A week later, the stitches are removed. However, full performance is restored only after a few days. However, the operation is very effective, it helps in 99%.


At the moment, no effective methods of prevention have been developed that would prevent the development of palm hyperhidrosis.
