Excessive sweating is an important problem for many people in terms of personal comfort and hygiene. First of all, let’s take a look at what excessive sweating is, how it happens, what are the causes.


Causes and Types of Sweating

Sweating is a physiological, that is, a normal phenomenon necessary for the control of body temperature and fluid-electrolyte balance. Sweating at a rate of 1ml/m2/min is considered normal. In case of excessive sweating, this figure can increase 30 times. For example, when the body temperature rises, sweat glands are activated through the sympathetic nervous system. In this way, the temperature in the skin with sweating decreases due to evaporation on the skin surface. However, some people may experience excessive sweating beyond physiological sweating.


Excessive sweating can occur not only in the armpits, face, scalp or hands and feet, but also in the whole body. Regional excessive sweating, which is related to the armpits, face, scalp, hands and feet, is a life-long condition that starts in adolescence and decreases relatively in advanced ages. Although its incidence in the community is around 4%, familial transmission is common. Although it can be continuous regardless of the season or activity, a significant increase in the amount of sweating is observed in the summer months or with physical activity. The main reason is that the sympathetic nervous system does not work properly.

The causes of non-regional, whole-body excessive sweating are slightly different. The most common causes are physical activity, high air temperature, stress, febrile diseases, menopause, obesity, some drugs, diabetes, various hormonal diseases (such as thyroid, adrenal gland, etc.) and some types of cancer.

Excessive Sweating and Social Problems

One of the most common problems faced by people who sweat excessively is the choice of clothes and sweat odor problems. Especially gray-toned clothes are very difficult to choose because they show sweating very much. In addition, social problems may occur due to the smell of sweat. People with excessive hand sweating feel the need to dry their hands before shaking hands with other people. These and similar social problems cause a vicious circle by increasing excessive sweating in the person with the effect of stress.

Over-sweating treatment

In order to treat excessive sweating, the underlying cause must first be investigated. Excessive sweating in the whole body can have one or more reasons as we have mentioned above. If these causes are treated, excessive sweating will also improve. In the treatment of regional excessive sweating caused by the sympathetic nervous system not working properly, there are various methods, including surgical and non-surgical methods. Botulinum toxin applications are the most preferred non-surgical methods. Excessive sweating treatment with Botox (botox) can be done successfully for armpits, hands and feet, and even the scalp. Botox acts by preventing the sympathetic nerves from stimulating the sweat glands. The duration of effect is around 4-6 months.

Sweating treatment with Botox is also suitable for people who do not have excessive sweating but are bothered by local sweating, such as a small amount of underarm sweating. Reducing or stopping the activity of sweat glands in this area does not have a negative effect on the general health of the person. On the contrary, it has positive social and psychological effects. The only application to be made in the spring will allow the person to spend the whole summer comfortably until the autumn.

Underarm sweating treatment with Botox is a very comfortable and short procedure. In patients whose sweating map is not clear, excessive sweating areas are marked with the iodine-starch test. Afterwards, numbing cream is applied to the relevant area and waited. In the follow-up, botox application is made with a 10-minute procedure, which will bring you 4-6 months of comfort. After the procedure, it is enough to stay away from hot water for 2 weeks and take a bath with warm water. Since the hand and foot areas are very sensitive, blocks with local anesthesia are preferred, not creams, for numbing these areas.

Apart from Botox, regional sweating can also be treated with surgery. By cutting the related sympathetic nerves, excessive sweating is prevented permanently. However, due to the high risks that may occur while cutting these nerves, this technique is not preferred much today. Instead, permanent treatment with subcutaneous laser application with surgical intervention to the sweat glands is more preferred.
