The main causes of hyperhidrosis

Hyperhidrosis is an extremely unpleasant disease, but it can be cured. Learn how to do this.

What it is?

Hyperhidrosis is an increased activity of the sweat glands, which leads to increased production of sweat.

Hyperhidrosis can be localized, in which increased sweating is observed only in certain areas of the body, or generalized, in which sweat is allocated literally throughout the body. Also, the primary form and the secondary one are identified. The first develops independently of any diseases and conditions, the second, as a rule, is the result of some health problems.

What causes hyperhidrosis?

In general, a person needs sweat, since it allows for thermoregulation. For example, a person sweats in the heat, with increased physical exertion, and so on. Evaporating moisture cools the body and allows it to maintain a normal temperature.

The sympathetic nervous system is responsible for the work of the sweat glands, which at the right moments sends signals and activates the glands.But if the work of this system for some reason has been disrupted, then sweat can be released at any time, regardless of the ambient temperature and the state of the person.

What are the causes of hyperhidrosis? They can be very different:

  • diseases of the thyroid gland, in particular hyperteriosis;
  • improper diet (excessive sweating or hot food can lead to excessive sweating);
  • some malignant neoplasms, for example, Hodgkin's lymphoma;
  • infectious diseases such as tuberculosis, malaria, syphilis, brucellosis, and some others;
  • wearing very narrow clothes made of thick, synthetic and breathable fabrics;
  • diabetes;
  • overweight or obesity;
  • menopause in women;
  • parkinsonism;
  • some diseases of the cardiovascular system, such as tachycardia;
  • cystic fibrosis;
  • frequent stress, increased nervous tension, overexcitement;
  • taking certain medications;
  • the consequences of a stroke (such a disease can lead to damage to the hypothalamus, as well as to impaired functioning of the thermoregulation center located in the brain).

Also, hyperhidrosis can develop independently, and in this case, the factor of influence in most cases is heredity.


Symptoms of hyperhidrosis can not be overlooked, because with this disease there is a significant and unreasonable increase in sweating. Sweat stands out regardless of what a person does, what is the temperature of the air. Sweating can be observed even in a calm state, including in the cold. The skin becomes very moist as well as cold. This causes severe discomfort.

As for the zone of occurrence of manifestations, hyperhidrosis of the feet and armpits is most common, since it is in these areas that the largest number of sweat glands are located. But other parts of the body can also sweat, such as the crotch, palms, groin folds, chin, the area above the upper lip, and so on.

Who to contact?

What doctor treats hyperhidrosis? Everything will depend on the reasons that provoked such a disease. In case of primary hyperhidrosis, which develops on its own and is not accompanied by other symptoms, it is necessary to consult a dermatologist.If there are other warning signs, then it is better to go to the therapist. He will schedule an examination, find out the cause of sweating, and refer you to the right specialist.


Diagnostics may include the following measures:

  • Evapometry. A special device is used that allows you to set the rate of evaporation of sweat from the surface of the body.
  • Gravimetry is a study in which a piece of filter paper with a specific mass is applied to dry skin. She remains on the body for some time, after which her weight is measured in order to determine the amount of sweat released.
  • General urine and blood tests.
  • Electrocardiogram.
  • Ultrasound examination of the thyroid gland.
  • Blood tests for infections.
  • Analyzes to determine the level of thyroid hormones.

How to treat?

Treatment of hyperhidrosis should be comprehensive and aimed primarily at eliminating the causes of the disease.

Therapy may include the following areas:

  1. Be sure to respect the rules of personal hygiene. Regularly shower and change clothes and underwear.You also need to use a deodorant, and if the perspiration is strong, and the sweat has an unpleasant smell, then the doctor may advise an antiperspirant who will reduce the sweat glands.
  2. Iontophoresis. This procedure involves the impact on the body of a constant galvanic current. Additionally, some medications or therapeutic compositions can be used.
  3. Botox (botulinum toxin) injections. In this way, armpit hyperhidrosis is treated. The fact is that Botox can block nerve impulses to sweat glands. And if they do not receive signals, then perspiration will noticeably decrease.
  4. Radiotherapy is also used. This method involves exposure to the body of radio waves.
  5. It is important and proper nutrition. It is necessary to exclude from the diet any foods that can lead to an acceleration of blood circulation. These include alcoholic beverages, spicy dishes, hot food, coffee, some spices.
  6. What to do if the above methods were ineffective? The only way out is surgical treatment. It can be carried out in several ways. The first is sympathectomy.Such intervention involves the removal of sympathetic ganglia, sending impulses to the glands. The second method is the removal of sweat glands. In the armpits, curettage is often performed, in which adipose tissue is scraped along with the glands. The third method is the most radical, since it involves the removal of areas of skin with the largest accumulations of sweat glands. The effect is 100%, but after the operation there will be unattractive scars.
  7. You can try to treat hyperhidrosis at home with folk remedies. So, some advise rubbing boric acid powder into the feet and armpits. Effective decoction of oak bark. In addition, you can use oak bark in a dry form, pouring it into socks and putting them on overnight. You can also make a decoction of sage. Try to wipe the sweating zones with a not too concentrated vinegar solution. In addition, you can make baths or compresses with a weak solution of potassium permanganate.

It remains only to wish to get rid of such a delicate problem as soon as possible.
