It is quite normal for a healthy human to sweat. It only becomes an issue when you sweat excessively even without any form of physical engagement . Sweating helps to maintain the body temperature. It also, expel toxins, which supports proper immune function and helps prevent diseases related to toxic overload.
Some people tend to sweat more than others. Usually, people sweat when engaged in some form of activities like walking, dancing, eating etc. It is also normal for people to sweat when they’re nervous because emotions can affect the sweat glands.
Excess sweat may be abnormal. Certain things might be the reasons and may also require medical attention. If heavy sweating has no underlying medical cause, it’s called primary hyperhidrosis. This type occurs when the nerves responsible for triggering your sweat glands become overactive and call for more perspiration even when it’s not needed
Hyperhidrosis, also known as polyhidrosis or sudorrhea, is a condition characterized by excessive sweating. The sweating can affect just one specific area or the whole body.
The excessive sweating associated with hyperhidrosis is normally most active in the hands, feet, armpits, and the groin because of their relatively high concentration of sweat glands.
- Focal hyperhidrosis: When the excessive sweating is localized. For example, palmoplantar hyperhidrosis is excessive sweating of the palms and soles.
- Generalized hyperhidrosis: Excessive sweating affects the entire body.
Hyperhidrosis may be present from birth or might develop later in life. However, most cases of excessive sweating tend to start during a person’s teenage years.
The condition can be due to an underlying health condition, or have no known cause:
- Primary idiopathic hyperhidrosis: “Idiopathic” means “of unknown cause.” In the majority of cases, the hyperhidrosis is localized.
- Secondary hyperhidrosis: The person sweats too much because of an underlying health condition, such as obesity, gout, menopause, a tumor, mercury poisoning, diabetes mellitus, or hyperthyroidism (overactive thyroid gland).
Excess sweating may not be linked to an underlying medical condition, however, it can make one uncomfortable and cause embarrassment especially, when it comes with body odour.
Signs and symptoms of hyperhidrosis may include:
- Clammy or wet palms of the hands
- Clammy or wet soles of the feet
- Frequent sweating
- Noticeable sweating that soaks through clothing
People with hyperhidrosis might experience the following:
- Irritating and painful skin problems, such as fungal or bacterial infections
- Worrying about having stained clothing
- Reluctant to make physical contact
- Socially withdrawn, sometimes leading to depression.
