Why do we sweat ?

Sweat is the body's mechanism for dissipating heat. Thus, people sweat more when the weather is hot, after exercise, or after stressful events that cause fear or anger.

What is hyperhidrosis ?

It is a health problem that causes more sweat than necessary to cool the body. Those affected by this condition seem to have overactive glands, especially in the groin, armpits, hands, feet and face.

What are the impacts of hyperhidrosis on those affected by it ?

This condition can affect self-confidence, can be distracting and affect work efficiency, can decrease patients' social comfort, emotional well-being and clothing choices.

Too few patients affected by this condition talk to their healthcare professional. This is often because patients do not know that excessive sweating is a treatable condition.

What are the causes ?

There are two types of hyperhidrosis, the primary one and the secondary one.

Primary or focal hyperhidrosis is of an unknown cause. However, the way in which it affects patients appears to be related to the overactive central nervous system, which leads to over-stimulation of the sweat glands. In this type of hyperhidrosis, at least one of these places should be affected: Armpits, hands, feet or face.

Secondary or generalized hyperhidrosis is caused by an underlying problem, such as obesity, hormonal disorders, nerve damage, etc.) To treat this type, one must treat the underlying problem.

What are the treatment options ?

Topical treatments:

- Antiperspirants: Substance put on the skin that will block the channels through which the sweat comes out (sweat ducts). For this condition, antiperspirants may contain 10 to 15% aluminum hydrochloride. Products containing higher percentages are also available by prescription. However, these products do have some unwanted effects, such as irritation of the skin and damaged clothing.

- Medicines: Some medicines are available under prescription, but since they tend to cause certain side effects, such as dry mouth, urinary problems and dizziness, this is not the first choice of treatment.

Iontophoresis:

It is a procedure that temporarily inactivates the sweat glands. A gentle electric current passes through tap water (conductive), to reach the electrodes (conductive), which bathe in the water that touches the skin. The current blocks the connection between the nerves and the sweat glands, which in the vast majority of cases reduces sweat. It is more for hyperhidrosis of the hands and feet.

Iontophoresis is generally considered a first or second line of treatment and is often prescribed when antiperspirants do not work.

This treatment does not include a needle or medication.

Thanks to the DermaDry device, it is now possible to do this treatment directly at home. This treatment can even be used for more severe cases of hyperhidrosis.

Bolutic toxin injection:

When local products are not effective enough, we can switch to injecting botox into the armpits. The injected toxin temporarily blocks the nerves that stimulate sweating. The full effect can be seen after a few days, but it lasts for a few months.

Surgery:

Consists of preventing the nerve signal commanding the sweat glands to produce perspiration. Otherwise, it involves extracting some of the sweat glands.

Non-pharmacological means to reduce sweating

1. Avoid triggers for sweating, such as coffee, alcohol, and spicy meals.

2. Loose clothing, especially under the armpits. Possibility of adding single-use pads to absorb sweat under the armpits.

3. On the feet, do not wear the same pair of shoes two days in a row to give them time to dry well. Carry a change of socks during the day.
