The scorching heat wave was also swept away. The morning and evening winds already herald autumn. The time has come to say goodbye to summer. There are people who have been looking forward to the coming summer. People who complain of discomfort due to excessive sweating, hyperhidrosis patients.

Our body starts to sweat when the skin feels hot and the body temperature rises above 37℃. Hyperhidrosis (多汗症) is a disease that literally causes excessive sweating. It is often localized, such as hands, feet, armpits, and face, rather than the whole body. It is known that 0.6-4.6% of the total population suffers from hyperhidrosis. It occurs mainly in the 10s and 20s.


Jeong Jin-yong, professor of thoracic surgery at Catholic University of Korea Incheon St. Mary’s Hospital, said, “Sweat is a natural physiological phenomenon that regulates body temperature by maintaining a constant skin condition and dissipating heat. Not only that, but in severe cases, it can lead to depression,” he warned.

If you sweat 2-5 liters a day, you suspect hyperhidrosis.

When the weather gets warmer or the body temperature rises due to exercise, the hypothalamus, which regulates the body temperature, sends out a heat loss signal. The signaled sympathetic nerves release neurotransmitters and sweat is secreted from the sweat glands stimulated by them. However, if you sweat excessively for no specific reason, you may suspect hyperhidrosis.


In general, an adult sweats 600-800 ml per day. Usually about 3 to 4 cups. In summer, 1 to 1.5 liters of sweat is sweated. On the other hand, hyperhidrosis patients excrete about 2 to 5 liters of sweat per day. Usually, 1 liter of sap that can be found in hospitals is equivalent to sweating 2 to 5 saps per day.

Some people sweat excessively when eating spicy or hot food, and this is also to lower the heat generated in the process of eating and digesting food. In addition, when the autonomic nervous system is stimulated by the sense of taste, you may sweat. The more stimulant the food, the better the response. Sweating when eating spicy food is a normal body reaction. different from hyperhidrosis. The same goes for sweat when you are nervous or anxious.

Hyperhidrosis, if it interferes with daily life, treatment is required

Hyperhidrosis is divided into localized hyperhidrosis and systemic hyperhidrosis according to the area of ​​sweating. According to the cause, it is divided into primary and secondary hyperhidrosis. Primary (primary) hyperhidrosis is caused by changes in the sympathetic nervous system or a temperature higher than 34°C in room temperature or emotional changes such as tension. Secondary hyperhidrosis is caused by endocrine diseases (hyperthyroidism, diabetes, hyperpituitarism, menopause), nervous system diseases (Parkinson’s disease, cerebrovascular disease, spinal cord injury), cancer (leukemia, lymphoma, kidney cancer), tuberculosis, family history, obesity, etc. is known as


Primary hyperhidrosis is characterized by ▲where sweating includes one localized area such as hands, feet, armpits, or face ▲Family history ▲Young age (under 25 years old) ▲Bilateral (symmetrical) ▲Once a week Abnormal excessive sweating ▲ When sleeping at night, 2 or more of the 6 symptoms, such as normal, persist for more than 6 months.

Jeong Jin-yong, a professor of thoracic surgery at Incheon St. Mary’s Hospital, said, “If hyperhidrosis interferes with daily life or makes social life difficult, treatment and management are necessary. Because hyperhidrosis has various causes and different symptoms, it is best to approach it according to the cause and condition to be effective.

Concerns about compensatory hyperhidrosis… Decide whether to have surgery or not

For the treatment of hyperhidrosis, topical medicines, oral medicines, iontophoresis therapy, and Botox (injection) procedures are applied first. Topical drugs are effective for local hyperhidrosis, safe and easy to apply. However, the effect is temporary and may irritate the skin. Oral medications are effective for systemic hyperhidrosis. However, there may be side effects such as dry mouth, dry eyes, and constipation. It should not be taken together with glaucoma or prostatic hyperplasia medications.

Iontophoresis is a method of treating hyperhidrosis of hands or feet by passing electricity through tap water. Usually, it takes 7 or more treatments to be effective. There are almost no side effects. Botox treatment is effective for underarm hyperhidrosis, and has a short treatment time and quick recovery. However, it is necessary to repeat the treatment every 6 months.

If there is no improvement in symptoms or if the symptoms are severe, consider surgical treatment (sympathectomy). Sympathectomy is a thoracoscopic surgical procedure that reduces sweat secretion by removing a part of the sympathetic nerve that transmits heat loss signals to the hypothalamus. The location of the sympathetic nerve to be excised is different depending on the site of hyperhidrosis. Sympathectomy can be particularly effective in patients with hyperhidrosis of the hand. However, as a side effect, ‘anhanjeung’, in which there is almost no sweat, may occur. There is a possibility of recurrence.

However, the most common side effect is compensatory hyperhidrosis. Compensatory hyperhidrosis refers to sweating in other parts of the body instead of sweating in the hands or feet. The most common areas are the back, chest, stomach, and buttocks. Compensatory hyperhidrosis is mild in 70-80% of patients after surgery.

Compensatory hyperhidrosis, which may occur after sympathectomy, may be experienced temporarily. The compensatory hyperhidrosis prediction procedure is a method of temporarily paralyzing the nerves that cause hyperhidrosis by injecting drugs through a thoracoscopy under local anesthesia. It has almost the same effect as the surgery and lasts for 1 to 7 days. During this period, you can experience whether or not compensatory hyperhidrosis develops in advance, the site, and the degree, and decide whether to have surgery.

Professor Jinyong Jeong said, “The treatment of compensatory hyperhidrosis is very difficult and it is not easy to return to the pre-operative state, so it is necessary to make a careful decision in consultation with the medical staff. It is important to find a way so that it can be controlled with a specialist,” he emphasized.
