However, there are a number of conditions in which sweat begins to be released too intensely, which indicates certain dysfunctions and brings significant physical and psychological discomfort to a person. According to statistics, about 3% of people of both sexes complain of hyperhidrosis.
Sweating is controlled by the autonomic nervous system, of which the parasympathetic nervous system is a part - a failure in its work can be either a consequence of other diseases or an independent violation.

- Primary hyperhidrosis is when excessive sweating is not associated with other diseases. Usually manifests itself in childhood or adolescence.
- Secondary hyperhidrosis - occurs against the background of other diseases.
Possible Causes of Hyperhidrosis
Primary hyperhidrosis is one of the most common causes of excessive sweating. It is based on the individual physiological characteristics of the organism.
On the one hand, people with primary hyperhidrosis have more sweat glands, on the other hand, sweat glands are more sensitive to various stimulating factors that cause sweating.
Usually, this type of hyperhidrosis manifests in childhood and intensifies in adolescence. This pathology is hereditary and is often transmitted from one of the parents. The severity can vary from moderate to very strong.
Secondary generalized hyperhidrosis is observed in infectious diseases in response to an increase in body temperature.
Purulent processes in the body, such as abscesses, phlegmon, and destructive pneumonia, can lead to sharp temperature fluctuations during the day.
These are serious conditions that require hospitalization, and often surgical treatment.
Excessive sweating can be the result of chronic infections - tuberculosis, malaria, brucellosis, etc.
Generalized hyperhidrosis is observed with endocrine pathologies - for example, with an increase in the level of thyroid hormones. In addition, there is a loss of body weight with normal appetite, heart palpitations, and emotional arousal. Patients with diabetes often complain of increased sweating - special attention should be paid to the appearance of cold, sticky sweat, which may indicate a sharp drop in blood sugar levels. Hormonal changes during pregnancy, with menopause, are often accompanied by hyperhidrosis.
People with oncological diseases of the hematopoietic system are characterized by increased sweating, especially at night. In addition, patients have no appetite, they lose weight, there is severe fatigue, body temperature can fluctuate between 37–38 ° C, and one or more groups of lymph nodes may increase.
Neurosis and panic attacks are often accompanied by increased sweating.
